fix(k9): validate K9 with the canonical validator; bring every K9 record to contract v1.0.0 - #464
Before this PR, all 14 tracked K9 files failed the canonical validator. The local hook did its own grep checks, which made it a second, looser validator. After this PR, the 10 files that are components all pass layers L0–L2. The other 4 are templates, renamed to .in.
Changes
dogfood-gate.yml, K9 job:
It runs metadatastician/standards1-formats/k9/tools/k9-validate.sh at the template's pin e064539, using Nickel 1.18.0 pinned by sha256.
It goes through the hardened template hook.
If the validator or nickel is missing, the job fails instead of passing at a lower layer.
The validation output that the summary job reads is kept.
.github/hooks/validate-k9.sh: replaced with the template's wrapper.
The six contractiles (must, trust, bust, intend, adjust, dust):
Each now has the v1.0.0 pedigree: schema_version, component_type, semantics and side_effects.
Each is a 'Yard declaration, as in the template: the paired runner does the execution, so this record spawns nothing.
The import of ../k9/template-hunt.k9.ncl is gone. That path never resolved.
variance_schema is marked not_exported, as in the template.
Echidna's own prose and invariants are unchanged.
Templates renamed to .in:svc/k9/template-{kennel,yard,hunt}.k9.ncl and examples/setup-repo.k9.ncl. A template is not a component. The two filled examples now use the template's current text with echidna's values.
container/deploy.k9.ncl: now a v1.0.0 Hunt component.
It declares capabilities, side effects and a signature block. The signature block is checked for presence only; the validator reports it as present but unverified (K9-C001) until the owner signs the file.
The PLACEHOLDER-SIGNATURE-REQUIRED-FOR-HUNT string and the sha256:placeholder checksum are removed.
Image, port, health check and scripts are unchanged.
setup-prover-env.k9.ncl: rewritten. It had never been valid Nickel (top-level bindings with no enclosing record). It now provisions provers only through manifests/live-provers.scm (Guix, the primary path) and the Wave-3 sealed containers. This drops:
an unpinned curl … elan-init.sh | sh from master;
sudo installs through apt and dnf;
installs through cabal and opam;
a fixed prover count that duplicated docs/PROVER_COUNT.adoc.
k9iser retired:k9iser.toml is deleted. No workflow ran it, so docs/ENV-VARS.adoc's statement that VERISIMDB_URL is "enforced by k9iser.toml:47" was untrue and has been corrected.
READMEs:contractiles/README.adoc and svc/k9/README.adoc are updated to match.
No action was added or removed, so actions.lock is unchanged.

Testing
With Nickel 1.18.0, STANDARDS_DIR=<standards@e0645391> bash .github/hooks/validate-k9.sh checked 10 files, and none failed. The same run against standards 8e48b1ca also passes.
Nothing else in the repository reads the changed K9 files. The contractile runners (<verb>.ncl) import only _base.ncl.
…ord to contract v1.0.0
WO-10 K9 lane for echidna (metadatastician/standards#1058), matching
rsr-template-repo (WO-9) and the merged panic-attack#253,
echidnabot#193 and proof-burrower#124.
- dogfood-gate k9-validate runs metadatastician/standards
1-formats/k9/tools/k9-validate.sh at the template's pin (e0645391),
with sha256-pinned Nickel 1.18.0, through the hardened template hook.
A missing validator or nickel now fails the job.
- The six contractiles carry the v1.0.0 pedigree and are 'Yard
declarations (the runner is the execution surface), as in the
template. The import of ../k9/template-hunt.k9.ncl, which never
resolved, is gone.
- svc/k9 templates and the setup-repo example are *.k9.ncl.in: a
template is not a component. The two filled examples follow the
template's current text.
- container/deploy.k9.ncl is a v1.0.0 Hunt component with capabilities,
side effects and a signature block (presence only). The
"PLACEHOLDER-SIGNATURE" string and "sha256:placeholder" checksum go.
- setup-prover-env.k9.ncl was never valid Nickel. It is rewritten to
provision provers only through manifests/live-provers.scm (Guix) and
the Wave-3 sealed containers, dropping an unpinned curl|sh install,
sudo apt/dnf installs and a stale fixed prover count.
Before: 14 of 14 tracked K9 files failed the canonical validator.
After: 10 of 10 (the four .in templates excluded) pass L0-L2 at both
standards 8e48b1ca and e0645391.

k9iser is retired estate-wide (WO-10). No workflow runs it, so
k9iser.toml enforced nothing, and docs/ENV-VARS.adoc's claim that
VERISIMDB_URL is "enforced by k9iser.toml:47" was untrue. K9 is now
checked by the canonical validator in dogfood-gate.

K9 validation now uses a standard validator, applying stricter checks when the required validation tool is available.
Setup options now support conditional Guix installation, sealed-container builds and a read-only health check.
Contract security settings now limit subprocess use and align evaluation with the Yard tier.
Documentation
Updated guidance clarifies how to complete and validate templates, and how component declarations relate to their paired runners.
Chores
Updated safety-tool annotations and code formatting without changing runtime behaviour.
The PR updates K9 contractiles, setup and deployment records, and validation. CI now installs pinned Nickel and checks tracked K9 files with the canonical validator. The PR also revises K9 guidance, removes the K9iser manifest, adds Hypatia suppressions to Zig casts, and reformats Rust test code.
Contractiles now use the base pedigree schema and Yard tier. They disable subprocess permission, mark variance schemas as not exported, and assign probe execution to paired runners.
The setup component replaces per-prover installation recipes with configurable Guix, container, prerequisite-check, and doctor recipes.
Deployment component record container/deploy.k9.ncl
The deployment configuration uses a top-level record with inline pedigree, scripts, and recipe records. The migration recipe uses separate build and up commands.
The hook validates tracked K9 files with the canonical validator. CI checks out pinned standards content, installs checksum-verified Nickel, and runs the hook.
K9 templates and repository guidance .machine_readable/contractiles/README.adoc, .machine_readable/svc/k9/README.adoc, .machine_readable/svc/k9/examples/*, k9iser.toml, docs/ENV-VARS.adoc
The READMEs describe contractiles and service templates. Example leash values use K9 literals. The K9iser manifest is removed, and the environment-variable entry no longer lists it as an enforcement source.
Source lint and formatting updates
Layer / File(s)
Summary
Cast suppressions and Rust formatting src/zig_ffi/chapel_bridge.zig, src/zig_ffi/runtime_owner.zig, src/rust/proof_search.rs
Zig casts gain Hypatia suppression comments without runtime changes. Rust test expressions are reformatted without behaviour changes.
hyperpolymath/echidna#476 — It makes overlapping formatting and Hypatia suppression changes in the same Rust and Zig files.
Merge Risk: Low · previous review 55bcf
The canonical validation update has bounded filename and local discovery problems, and the documented Nickel commands need envelope handling. These warrant fixes or explicit follow-up, but no broad deployment or runtime failure is established.

Explanation
The title names the two main changes: K9 validation through the canonical validator, and bringing K9 records to contract v1.0.0. The raw summary and objectives confirm both are central to the changeset (validate-k9.sh and dogfood-gate.yml, plus the contractile, container and setup records). It is a single line in conventional-commit form and is specific enough for a teammate scanning history.
Full details: Description check
Explanation
The description follows the template's main sections: Summary, Changes, Testing and a Required/As Applicable checklist. It explains the purpose, lists the changed files, and reports the validation run. Several template items are not addressed. The Required checklist omits 'Tests pass' and 'Code is formatted', and the Summary does not link an issue with 'Closes #N'. The Screenshots section is also absent, though it is optional. The 'As Applicable' list is incomplete, with no CHANGELOG or ROADMAP note. Most required information is present, so the check passes, but the author should confirm the omitted test and format items.

cargo audit fails on rmcp 3.5.0 (crates/echidna-mcp) with
RUSTSEC-2026-0457 (fixed >=3.7.0), RUSTSEC-2026-0461 (>=3.6.0) and
RUSTSEC-2026-0462 (>=3.9.0), published after main last passed the
Dependency audit check. `cargo update -p rmcp` moves rmcp and
rmcp-macros to 3.9.0, inside the existing "3" requirement; no other
entry changes.

Dependency audit failed on 243752e, but this PR's diff didn't cause it. cargo audit now flags rmcp 3.5.0, a dependency of crates/echidna-mcp, with RUSTSEC-2026-0457, -0461 and -0462. Those advisories were published after main last passed this check.
The fix is in #465: a lockfile-only bump of rmcp to 3.9.0, after which cargo audit is clean and cargo check -p echidna-mcp --locked passes. I've merged that commit into this branch (39b335e), so CI re-runs with it.
`cargo fmt --check` fails on main (2ab7574) in five places in
src/rust/proof_search.rs, so rust-ci 'Cargo check + clippy + fmt' is
red on every PR. Formatting only; no code change.

Hypatia's code_safety/zig_ptr_cast and zig_align_cast now flag the nine
`@ptrCast(@aligncast(raw))` lines in src/zig_ffi/chapel_bridge.zig and
src/zig_ffi/runtime_owner.zig as high, and the governance Hypatia
baseline gate is red on main (2ab7574) as a result.
Each of those lines recovers a callback's own `*@this()` from the
type-erased `*anyopaque` it was registered with (runtime_owner.Work
.context, or a std.mem.Allocator vtable's ptr), so the cast restores the
original type and alignment. Fixed at source with a reasoned inline
`hypatia: allow` per rule on each line, as the scanner documents,
rather than a baseline entry. No code change: comments only.
Checked by simulating ScannerSuppression.inline_allowed?/4 and
directive_re at hypatia 82396d81 (the CI pin): 18 unsuppressed
findings on main, 0 with this change. The scanner itself could not be
built here (hex.pm is unreachable).

governance / Validate Hypatia Baseline: four new high findings, code_safety/zig_ptr_cast and zig_align_cast, on the nine @ptrCast(@alignCast(raw)) context-recovery casts in src/zig_ffi/. Each cast is sound: it restores a callback's own *@This() from the pointer it was registered with. Fixed at the source by fix(ffi): annotate the audited Zig context-pointer casts for Hypatia #468, which adds a reasoned inline hypatia: allow directive per rule and no baseline entry.
rust-ci / Cargo audit has the same cause as Dependency audit, so #465 covers both. All three fixes are merged into this branch (head 21864aa).
State on 21864aa, which includes the fixes from #465: every K9, Agda and Idris2 gate passes. Two checks are still red, and neither is caused by this PR's diff:
This security review couldn’t start because the paying account has exhausted its Codex allowance and has insufficient available credits. The payer can check their balance and add credits in the Codex usage dashboard, then try again. If you do not manage the paying account, contact this repository's admins.
Review on #464 (Codex): install-all depended on install-guix even with
config.use_guix = false, never ran install-containers when
use_sealed_containers was true, and ran doctor even with run_doctor false.
check-prerequisites also said a missing guix would be skipped, when it would
not have been.
install-all's dependency list is now built from config, and
check-prerequisites fails loudly when an enabled path's tool is missing.
Disabled paths are neither checked nor run. Nickel evaluates the file, and
the canonical validator passes (10 files, 0 failing).

Read tracked paths as NUL-delimited records.
When a tracked K9 pathname contains non-ASCII characters or a quote, Git can emit a quoted pathname. The validator then rejects the file as missing, so the CI gate fails. Use git ls-files -z and read NUL-delimited records.

Gate the just prerequisite on enabled recipes
When install-all is configured for Guix only (use_guix = true, use_sealed_containers = false, and run_doctor = false), this unconditional check still requires just, although the remaining install-guix recipe invokes only guix. A Guix host without just therefore fails before provisioning; include this check only when the container or doctor path is enabled, as is already done for the other tools.

Synchronize the registry with the Yard tier changes
Changing this component—and the bust, intend, and must components—to Yard leaves the machine-readable discovery metadata contradictory: .machine_readable/contractiles/INDEX.a2ml lines 47, 79, 113, and 129 still classify them as Hunt or Hunt-read-only, and their coherence manifests retain the same Hunt claims. Because the README explicitly directs consumers to discover verbs through INDEX.a2ml, tier-based tooling can continue requiring Hunt signatures or granting the wrong capability classification; update the registry and manifests alongside these tier changes.

Summary
This is WO-10's K9 lane for echidna (metadatastician/standards#1058). It follows the pattern already merged in hyperpolymath/panic-attack#253, hyperpolymath/echidnabot#193 and hyperpolymath/proof-burrower#124, and matches rsr-template-repo after WO-9.
Before this PR, all 14 tracked K9 files failed the canonical validator. The local hook did its own grep checks, which made it a second, looser validator. After this PR, the 10 files that are components all pass layers L0–L2. The other 4 are templates, renamed to
