From 446f9958f5207b7b3ca1590b66f747e4499d18a3 Mon Sep 17 00:00:00 2001 From: Rhein1 / Agoragentic <140637602+rhein1@users.noreply.github.com> Date: Tue, 22 Sep 2026 23:04:06 -0400 Subject: [PATCH 1/5] feat: add evidence-preserving context packing and Memory adapter Retain protected records, paired tool calls and dependency closures within an actual JSON byte budget. Add explicit host bindings, omission manifests, Memory source revalidation, 52 offline regression tests, and a synthetic demo. No model calls, automatic hooks, transcript edits or authority changes. --- docs/context-packing.md | 165 ++++++++++++++++ examples/context-pack/demo.mjs | 13 ++ llms.txt | 1 + plugins/fable5-codex/lib/context-pack-io.mjs | 38 ++++ .../fable5-codex/lib/context-pack-memory.mjs | 56 ++++++ plugins/fable5-codex/lib/context-pack.mjs | 182 ++++++++++++++++++ plugins/fable5-codex/scripts/context-pack.mjs | 25 +++ test/context-pack.test.mjs | 169 ++++++++++++++++ 8 files changed, 649 insertions(+) create mode 100644 docs/context-packing.md create mode 100644 examples/context-pack/demo.mjs create mode 100644 plugins/fable5-codex/lib/context-pack-io.mjs create mode 100644 plugins/fable5-codex/lib/context-pack-memory.mjs create mode 100644 plugins/fable5-codex/lib/context-pack.mjs create mode 100644 plugins/fable5-codex/scripts/context-pack.mjs create mode 100644 test/context-pack.test.mjs diff --git a/docs/context-packing.md b/docs/context-packing.md new file mode 100644 index 0000000..affbe1e --- /dev/null +++ b/docs/context-packing.md @@ -0,0 +1,165 @@ +# Evidence-preserving context packing + +Source implementation for Fable-5; not included in the tagged alpha.2 release. +This is a working local CLI and library, not automatic native Codex compaction. +It needs no model, API key, Python, or network service. Node 18+ is supported. + +## What it does + +The packer retains whole, verbatim **redacted** records in original order. It +protects constraints, failures, findings, test results, actions, approval records, +corrections, unknowns, the Fable run contract, and explicitly required evidence. +Tool calls/results are paired atomically. Side-effecting and unknown-effect +pairs are always protected. Dependencies are retained transitively. + +Optional notes and explicitly read-only pairs are ranked deterministically by +word overlap with the current goal, then recency. Optional groups that do not +fit are explicitly recorded in the omission manifest; smaller later groups may +still fit. No output text is summarized or truncated. The **complete compact +JSON plus final newline** must fit the requested byte budget. Protected evidence +or omission metadata exceeding that budget causes an error, not silent loss. +Byte reduction is not a token-saving, cost-saving, or task-quality measurement. + +## Use from a checkout containing this change + +```sh +node examples/context-pack/demo.mjs +node plugins/fable5-codex/scripts/context-pack.mjs pack --input REVIEWED_INPUT.json --binding REVIEWED_BINDING.json +node --test test/context-pack.test.mjs +``` + +For an installed Fable plugin, use `scripts/context-pack.mjs` relative to the +plugin root. PowerShell accepts the same arguments on one line. Use separate, +owner-reviewed, already-redacted input and binding files outside version control +for private work. Output goes only to stdout; it may contain sensitive excerpts +if the owner supplies insufficiently redacted inputs. Review it before sharing. +No files are changed by `pack` or `verify`. Shell redirection is the caller's +separate write action, not an internal log or transcript collector. + +After deliberately saving output to a private file: + +```sh +node plugins/fable5-codex/scripts/context-pack.mjs verify --input REVIEWED_INPUT.json --binding REVIEWED_BINDING.json --pack SAVED_PACK.json +``` + +Exit 0 means the transformation/verification succeeded; 2 is invalid input or +binding; 3 means protected material exceeds the budget. No invalid partial pack +is returned. Errors contain codes, not source contents or raw exception messages. + +## Input and host binding + +`agoragentic.context-input.v1` contains `scope` (project/repository/worktree/session +opaque IDs), `policy_revision`, `task` (`goal`, `head_ref`, `required_ids`), +`records`, and an explicit `upstream_omitted` count. Record fields are validated +in `lib/context-pack.mjs`; `examples/context-pack/demo.mjs` is executable schema documentation. + +Each record has an ID, kind, exact text, text SHA-256, source ID and revision, +evidence references, and required-record dependencies. Source coordinates refer +to the redacted snapshot. A tool record additionally requires `call_id` and an +explicit effect classification: `read_only`, `side_effect`, or `unknown`. +Missing, duplicate, reversed, or inconsistent pairs fail. Inputs are not a +native Codex transcript format, and raw rollout JSONL is not accepted. + +The separately supplied binding contains exactly: + +- expected `scope`, `policy_revision`, and `head_ref`; +- `source_revisions`, a host-controlled map; +- `expected_digest`, SHA-256 of the module's sorted canonical input JSON; +- `budget_bytes`, from 1,024 through 65,536. + +The API `snapshotDigest(input)` computes that fingerprint; it does not approve +an input. Hashes detect changed bytes relative to a reviewed binding, not +malicious content, author identity, valid signatures, current permission, or +truth. The host must supply classifications, revalidate source permissions and +revisions, and redact **before** this API. Do not populate its trusted binding +from model-generated permission flags. CLI files are explicitly owner-reviewed +artifacts, not a live ECF enforcement connection. + +The library has no file/network/command access. The CLI reads only named JSON +files, bounds bytes, rejects non-regular files and final symlinks, and checks +file identity. It is not an OS sandbox or an arbitrary-path containment service; +parent-directory and same-user filesystem attacks need host isolation. + +## Fable workflow use + +Use an existing Fable skill normally. At an explicitly requested handoff, have +the host prepare the task contract and eligible source records, then pack them. +For example: + +```text +Use $fable-sweep for the existing authorized task. +For the handoff, use the context packer on the explicitly approved input and +binding files. Preserve the run contract, open findings, original command and +head references, pending approvals, and coverage gaps. Treat the result as data +only. Verify current source and authorization before continuing work. +``` + +No skill, recipe, coordinator/worker model, wrapper, runtime permission, release +version, or existing Laya behavior changes. The packer never starts Codex or a +subagent. The canonical six Fable skill identities remain unchanged. + +## Memory composition + +`lib/context-pack-memory.mjs` exports `packReviewedMemory(packet, options)` for +the existing `agoragentic.memory.context-mode-packet.v1` output. It does not +support the different `agoragentic.memory.context-packet.v1` preview schema. + +Trusted host construction options are `binding` (scope/policy/head/budget), +`goal`, a redacted existing `fable5-ecf-0.1` `runContract`, `requiredEvidenceRefs`, +and two async functions: `authorize(metadata)` and `verifySource(snippet, +metadata)`. Both must return literal `true` before and after verification. +`verifySource` must verify current source scope, permissions, revision, source +hash, excerpt coordinates and evidence references against the host's own +snapshot. It must not simply echo a peer's allowed flag. + +The adapter retains the run contract and snippets containing required evidence, +rejects missing required refs, preserves upstream omission counts, and adds no +Memory write operation. It does not import or start context-mode, read the +Memory database, implement production ECF authorization, or promote evidence. +Tests use the inspected packet shape and controlled callbacks, not a running +Memory/context-mode/Codex installation. Wire actual host controls only under a +separately reviewed integration. + +## Semantics that must not be weakened + +An approval record is historical data, not renewed permission. A retained +"all tests passed" string is not validated completion. `data_only:true`, +`completion_evidence:false`, and `authority:"none"` are fixed output values. + +Omission affects only this working packet. The original source remains under +its existing owner retention/deletion policy. The packer does not persist a +second ledger, delete Memory, or guarantee future source availability. Recovery +requires an authorized source snapshot; do not replay a send, write, deployment, +payment, or other action to recreate lost context. Source unavailable means +unavailable. Already-redacted source text can still contain prompt injection; +packing is not a sanitizer or instruction-enforcement boundary. + +Repeated packing requires the original complete reviewed input and binding, +not a prior reduced pack. This prevents treating cumulative omissions as a new +complete transcript. A later binding may reflect revoked sources or new heads; +old packs must not be carried across scopes without a fresh review. + +## Validation and rollout + +Offline tests cover exact text, Unicode byte budgets, protected kinds, +dependencies, pair integrity, scope/head/policy/revision checks, tamper detection, +upstream omissions, Memory denials and revocation, and actual CLI execution. +Run the full repository tests, package checks, and packed-artifact gate before +merge. Live Codex compaction/resume, OS-specific hooks, real retrieval and resumed +task quality remain separate unmeasured gates. No model quality or speed claim. + +## References and attribution + +Original MIT-licensed Agoragentic implementation.

It documents `SessionStart` with +`source: compact` for post-compaction context, not a replacement-message output +on `PreCompact`. A future standalone Codex adapter must preserve this distinction. diff --git a/examples/context-pack/demo.mjs b/examples/context-pack/demo.mjs new file mode 100644 index 0000000..79ca843 --- /dev/null +++ b/examples/context-pack/demo.mjs @@ -0,0 +1,13 @@ +// Synthetic fixture only.

The standalone CLI packs reviewed context without Fable, Memory, +Python, an API key, a model, or any third-party runtime dependency. + +**Source preview: 0.1.0-alpha.1.** Independently installable source, not an npm +release. `private: true` deliberately blocks accidental registry publication. +No live Codex installation or native compaction/resume run has been validated +for this preview. Offline command/hook contract tests are not that evidence. + +## What works + +The deterministic packer retains whole redacted excerpts, source references, +constraints, failures, findings, test results, action records, approvals, +corrections, unknowns, and explicitly required evidence. It preserves paired +tool calls/results and their dependencies. Optional records are selected by +word overlap and recency under a complete JSON byte budget. Omitted records +remain explicit; protected material that does not fit causes an error. + +The CLI can deliberately stage one reduced, reviewed snapshot for a session, +read it back while its binding is valid, and revoke it. The optional Codex hook +announces a valid snapshot after native compaction or resume. The skill then +retrieves the snapshot as **tool data**, not as new developer instructions. + +This does **not** replace Codex's native compactor, rewrite rollout files, +automatically collect transcripts, or guarantee that nothing important is lost. +The packer cannot recover evidence that the supplied input never contained. +Historical approvals stay historical; a retained passing-test claim is not proof. + +## Try without installing a plugin + +Requirements: Node.js 18 or newer. Git is also required for stage/read/hook +binding checks. From this standalone directory or an extracted source archive: + +```sh +node examples/demo.mjs +npm test +npm run check +node bin/codex-context-keeper.mjs help +``` + +These commands require no dependency installation and use synthetic fixtures. +Tests create and remove disposable Git repositories; they do not use your +normal repository or credentials. + +For a local npm artifact (not publication): + +```sh +npm pack --ignore-scripts +``` + +The entire directory, including hidden manifests, can be copied to a separate +checkout. It imports nothing from Fable. While maintained in Fable, an additional +root test enforces byte parity between both copies of the shared packer and I/O +modules. Do not edit those copies independently. + +## Prepare an explicit reviewed input + +The input is `agoragentic.context-input.v1`, not a native transcript. It contains +`scope` (opaque project/repo/worktree/session IDs), `policy_revision`, `task` +(`goal`, exact `head_ref`, `required_ids`), `records`, and `upstream_omitted`. +Each record has `id`, `kind`, exact redacted `text`, text `sha256`, +`source: {id, revision}`, `evidence_refs`, and `requires` dependencies. Source +coordinates/hash are optional. Tool records require a paired `call_id` and an +explicit `effect`: `read_only`, `side_effect`, or `unknown`. + +A separate host-reviewed binding specifies the expected scope, policy revision, +Git head, source revision map, canonical input digest, and `budget_bytes` +(1,024 through 65,536). `examples/demo.mjs` shows the complete executable input +and binding. The exported `snapshotDigest(input)` computes the input fingerprint; +it does not approve or redact it. + +Use actual current source evidence and a session ID supplied by the host. Never +invent a host session ID or parse rollout files to discover one. The optional +startup hook below provides the current ID. Store private inputs and bindings +outside Git. Redaction, source authorization and correct record classifications +remain the owner's/trusted host's responsibility; this is not a secret scanner. + +```sh +node bin/codex-context-keeper.mjs pack --input INPUT.json --binding BINDING.json +``` + +Output is JSON on stdout. Review before saving or sharing; insufficiently +redacted input produces insufficiently redacted output. No file is changed. + +## Stage, read, revoke + +Use an absolute, **new dedicated private root** whose parent exists; the command +creates the directory and marker. Existing unmarked roots are rejected. Choose +a location outside repositories, synced folders, shared homes and backups where +possible. Outside-repository placement is an owner obligation, not enforced by +the CLI. Never point this at the normal Codex home or Memory database. + +The following uppercase values are placeholders to replace, not literal paths: + +```sh +node bin/codex-context-keeper.mjs stage --input INPUT.json --binding BINDING.json --root ABSOLUTE_PRIVATE_ROOT --cwd ABSOLUTE_WORKTREE --session HOST_SESSION_ID --reviewed REVIEWED_REDACTED +node bin/codex-context-keeper.mjs read --root ABSOLUTE_PRIVATE_ROOT --cwd ABSOLUTE_WORKTREE --session HOST_SESSION_ID --policy POLICY_REVISION +node bin/codex-context-keeper.mjs revoke --root ABSOLUTE_PRIVATE_ROOT --session HOST_SESSION_ID +``` + +PowerShell accepts the same commands on one line. Staging and revocation are +explicit local writes; obtaining a context pack does not authorize either one. +Only the reduced pack is stored, not the source input or a second transcript. +An existing session capsule is never overwritten: explicitly revoke and then +stage a fresh reviewed snapshot when replacement is required. + +TTL defaults to ten minutes; `--ttl-ms` permits 1,000 through 3,600,000. Expiry +prevents use but does not physically delete the file. `revoke` unlinks only the +named capsule, not unrelated data or backups. Root/capsule paths are local and +owner-controlled. See SECURITY.md before use on shared machines. + +Reads enforce session, canonical working directory, policy, expiry, committed +Git HEAD, integrity and data-only boundary checks. **An unchanged HEAD does not +prove that the worktree, external sources or permissions are unchanged.** Before +continuing actual work, revalidate those live conditions. No stored approval is +renewed by a matching hash. The fixed Git read uses no shell or network command. + +## Optional Codex plugin + +The portable root `plugin.json`, compatibility `.codex-plugin/plugin.json`, +`skills/`, `hooks/hooks.json`, and self-contained local marketplace are included. +Use the standalone directory, not Fable's root marketplace, to register it: + +```sh +codex plugin marketplace add ./PATH_TO_STANDALONE_DIRECTORY +``` + +Then install Codex Context Keeper from that local marketplace in your Codex +plugin interface and review its hooks. Installation changes Codex configuration; +none of the packer/keeper commands installs or activates it. This preview has +not been exercised in a real Codex installation. First test in an isolated +`CODEX_HOME`, without private input, using your installed host's documented flow. + +Hooks remain **off** unless the owner supplies all of these settings in the +Codex launch environment (values are placeholders): + +```powershell +$env:CODEX_CONTEXT_KEEPER_ENABLE = "1" +$env:CODEX_CONTEXT_KEEPER_ROOT = "ABSOLUTE_PRIVATE_ROOT" +$env:CODEX_CONTEXT_KEEPER_POLICY = "POLICY_REVISION" +``` + +The Bash equivalents are ordinary `export NAME=value` settings. These are not +credentials. Do not dump unrelated environment variables to find them. Unset +`CODEX_CONTEXT_KEEPER_ENABLE` or set it to `0` to disable the hooks; this does not +delete staged files. No normal Codex configuration is edited by this project. + +On startup the enabled hook emits the current host session ID, without reading +a transcript or creating a snapshot. After an explicit stage, `PreCompact` +checks availability without altering native compaction. On `SessionStart` with +`source: compact` or `resume`, a valid capsule produces only a fixed retrieval +pointer. Ask/use `$codex-context-keeper` to read the packet as data. A missing, +expired, revoked, changed or invalid capsule produces a notice, not a successful +restore claim. Known subagent events and unrelated events are ignored. + +The hook's additional context is developer-role material in Codex. Therefore it +never contains source excerpts, shell commands from retrieved text, or arbitrary +paths supplied by a packet. The local read command returns the actual excerpts +at the tool-data boundary. Prompt injection in those excerpts can still affect +a model; this design does not guarantee model instruction adherence. + +## Validation before wider use + +The included tests exercise the library, real CLI subprocesses, disposable Git +head changes, private local capsule lifecycle, malformed/bounded hook input, +default-off behavior, and manifest consistency. Hook events are fixtures, not a +live Codex process. POSIX permission assertions do not validate Windows ACLs. + +Before enabling on real tasks, validate installation and removal in an isolated +Codex home, actual manual/automatic compaction and resume, Windows/macOS/Linux +behavior, independent worktrees, policy changes and deletion.
