Repair the failing CI and scanner paths, preserve the routing/proof audit, and make runtime and assurance claims match executed evidence. The original audit, Agda modules and quarantined Logtalk source remain in the repository, including the routing and rule-engine report and the source-bound proof-status ledger.
Published changes
Current head: 3f475120eaefffec9c964f433e26d9f6a85bb526.
Repair the original Agda, Cargo Audit, reusable Rust audit and T1 Guix failures. All four passed at d11ba46. The Agda changed-file selector also drains its input under pipefail; the 20,001-path regression reproduced the former false negative.
Retain concurrent main changes through b7221ae and the official regenerated native lock from run41917538023. No native identity or checksum was hand-edited.
Correct the plural prover route and GraphQL default/override contract. The current follow-up adds an actual binary-without-override startup test at 127.0.0.1:8082.
Bound version probes, close their stdin and kill/reap cancelled or expired children. Preserve hostname resolution, legitimate unavailable-IPv6 handling, and zombie-aware process controls without treating inspection failures as success.
Permit fixed-name static-analysis artifacts to be replaced on a rerun; same-run rerun execution still needs its own receipt.
Add the missing real Chapel final link and runtime initialization, with distinct real/stub modes, compiler-derived dependencies and behavioral controls. Both container recipes now include build.rs/build_support; the alternate also includes workspace members, benches and a locked build.
Executed qualification
The preceding head 346a31df421e7dc4972119d71b49684a0e6ffda3 has exact-tree receipts: merge checkout c8d1605 has the identical tree d2d7ae58b7016d8a37d754a6618c21b4a3f46195.
Both real corpus-hazard ingestion tests ran in those suites. They establish detection of the checked-in Isabelle/Lean hazards, not theorem validity or a severity exemption. The raw Critical findings remain.
Current 3f requires its own qualification. Its real Chapel job now passes export checks, five native-link controls and the Zig bridge build, but the packaged compiler's runtime-layout query still fails. Formatting and two new Sonar findings are being corrected; the existing #416 waiver has not been widened.
Panic Attack PR258 must qualify upstream before consumer adoption. The older scanner correctly reports incomplete coverage, and the fleet deposit must not treat that as a successful scan. The original audit's open semantic proof obligations, current security/quality findings, actual review state and required checks remain distinct from a passing test suite. No live learning or permanent estate-wide closure is claimed.
…ecked module
PROOF-POLICY §2.1 canonical invocation now runs and passes:
agda --safe --without-K --cubical-compatible src/Echidna/MetaChecker.agda
exit 0, 98s cold, 9 modules + 214 stdlib modules, 0 postulates, 53
-W[no]UnsupportedIndexedMatch warnings at 5 sites. Recorded as a limit
(--cubical-compatible is not --cubical; --cubical fails inside stdlib 2.1).
- AxiomTrackerCompleteness.agda was outside every gate and did not parse.
Fixed (Data.Sum import; clean-left-neutral; new worst-ub-right) and wired
into MetaChecker. CI now fails if any module yields no interface.
- New: Integrity.agda (E11; proves the invariant dispatch.rs 642/848/998 and
solver_integrity.rs 359 violate), ClampTrust.agda (ClampTrustBounds rewrite),
Receipt.agda (receipt vs warrant, from epistemic-types@5422cd5).
- meta-checker flags in CI; PROOF-STATUS R4 argued->proven plus R9-R11;
PROOF-NEEDS + report §10; D9 cross-reference.
Grade unchanged at Mathesis Grade 3: no Rocq/Lean leg ran (no reachable
release host), so R5 stays open and no leg is reported as passing.

Bug Fixes
Corrected container startup commands and health-check routes.
GraphQL startup and client configuration errors now return contextual errors instead of panicking.
Improved error handling for malformed inputs, unavailable services and failed prover checks.
New Features
GraphQL now defaults to 127.0.0.1:8082, separate from the core server on port 8081. Set ECHIDNA_GRAPHQL_ADDR to choose another address.
Documentation
Clarified interface ports, routing, health-check scope and proof-status limitations.
Tests
Added coverage for startup, error handling, proof checks and malformed inputs.
This pull request adds Agda proof models and checks, changes GraphQL listener configuration and container probes, and updates Rust error handling. It also revises CI automation, proof records, repository metadata, and documentation of routing and verification limits.

Summary
Listener and container behaviour .machine_readable/descriptiles/META.a2ml, src/interfaces/graphql/*, container/*, Containerfile, stapeln.toml
GraphQL defaults to 127.0.0.1:8082 and reads ECHIDNA_GRAPHQL_ADDR. Container startup uses server, health probes target /api/health, and the runtime entrypoint uses /app/echidna.
Health-lock, version-probe, parser and conversion errors are returned or handled. FFI message and error buffers use thread-local storage with documented lifetimes.
Runs dependency audits through repository scripts, provisions selected prover tools and runs backend-specific tests. Guix resolves a documented packaged subset.

Uses receipts to qualify scanner results and deposit findings. Manifest checks gain regression coverage, and the dogfood gate requires successful validation outcomes.
Workflow and repository records .github/workflows/*, Containerfile, archive/logtalk/*, docs/SSG_ROADMAP.adoc, docs/HTTP-CLIENT-COMPATIBILITY.adoc, docs/PROOF-STATUS.adoc

The new caveat at Lines 106–111 says no caller attaches an integrity checker. This opening statement still says solver binaries are checked before invocation. Readers can therefore rely on a guarantee the current pipeline does not provide. Update the invariant to state that solver identity is currently assumed.

Review comments at @.github/workflows/agda-meta-checker.yml:
- Around line 123-124: Update the Agda interface check using the src and iface
logic to enumerate source modules recursively and verify that each source has
its corresponding interface; do not rely on aggregate counts that can omit
nested modules or let unrelated interfaces offset missing ones.
Review comments at @container/entrypoint.sh:
- Around line 25-27: Update the image health check associated with the `echidna
server` startup command to probe `/api/health` instead of `/health`, preserving
the existing port and failure behaviour.
Review comments at @docs/DEBT.adoc:
- Around line 491-494: Update the POST /api/prove description in the debt entry
to say that the build feature determines whether an HTTP proof enters the
dispatcher/trust pipeline, not whether it is arbitrated. Preserve the
distinction that ProverDispatcher::verify_proof returns a single-prover result,
while verify_proof_cross_checked creates an arbitration verdict.
- Around line 485-486: Update the D9 evidence block so its commands verify the
listed acceptance paths and cited Agda proof, using symbol-based searches and
the canonical Agda invocation; alternatively, narrow D9 to the facts established
by the existing searches for with_integrity_checker and PLACEHOLDER.
- Around line 521-529: Add a reproduction command to the D12 entry that locates
the publishing workflow and verifies the `docs-site` claims; if the finding
cannot be reproduced with commands, explicitly mark D12 as a report-only
assertion.
- Around line 461-464: Qualify the `Uninitialized` statement in the
integrity-checker discussion: `verify_solver` returns `Missing` when the solver
binary is absent, and returns `Uninitialized` for a placeholder hash only when
the binary is installed.
Review comments at @docs/ECOSYSTEM-INTEGRATION.adoc:
- Line 124: Revise the documentation statement about the security learning rules
to limit the finding to the repository: say that no in-tree consumer loaded
them, rather than claiming they are loaded by nothing; retain the existing
`argued` qualification.
- Line 120: Update the document’s *Last Updated* metadata to 2026-11-01 to match
the correction date, or explicitly label the existing date as a historical
snapshot.
Review comments at @docs/PROOF-STATUS.adoc:
- Around line 230-233: Update the R4 receipt entry in the proof-status ledger to
record that `receipt-from-check` requires an uninhabited discriminator, since
`≈-cross` prevents supplying a proof from `w-here ≈ w-there` to `⊥`; also note
that the model proves no receipt exists at either world.
- Around line 340-341: Update the status summaries in PROOF-STATUS and the
routing-and-rule-engine reconnaissance report to reflect the ledger: rows R4,
R9, R10 and R11 are marked proven, so the claim that no row is above argued is
stale.
- Around line 202-205: Revise the E11 guarantee in the proof-status and
proof-needs claims to apply only when binaries have distinct digests; `≈d-sound`
establishes soundness of the digest comparator, not collision resistance between
binary contents. Keep the claim aligned with the digest-only model in
`Integrity.agda` rather than implying that different binaries cannot share a
digest.
Review comments at
@echidna-playground/.machine_readable/descriptiles/NEUROSYM.a2ml:
- Line 12: Update the last-updated field in the NEUROSYM metadata to reflect the
2026-11-01 retirement note, or clearly define it as the source-snapshot date and

Review comments at @meta-checker/src/Echidna/ClampTrust.agda:
- Around line 13-20: Update the obligation list in the module header to match
the lemmas actually proved: remove clamp-roundtrip, include clamp-fixed-0,
clamp-above, and clamp-idempotent, and correct the stated obligation count to
match the list.
- Line 1: Add the required SPDX header as the first line of ClampTrust.agda,
before the existing separator and module description.
Review comments at @meta-checker/src/Echidna/Integrity.agda:
- Line 1: Add the required SPDX license identifier as the first line of the new
file, before the existing separator comment, using the repository’s required
MPL-2.0 identifier.
- Around line 133-137: Replace sharpness-matters, which only proves true and
false are unequal, with a refutation of the soundness property for
UnsoundHash._≈d_ and always-true, using the true/false case to derive the
contradiction. Update the adjacent comment to describe that theorem, and remove
the claim that a manifest verifies a binary with a different digest unless the
file proves it.
Review comments at @meta-checker/src/Echidna/MetaChecker.agda:
- Line 64: Update the TOTAL summary comment in MetaChecker to distinguish
postulates from hypotheses: remove the claim of zero assumptions and state that
some proofs are conditional on Hash.≈d-sound in Integrity and the discriminates
parameter in Receipt.
Review comments at @meta-checker/src/Echidna/Receipt.agda:
- Line 159: Update the Asserts proven-with-postulates definition so its Receipt
type explicitly includes the named axiom assumptions, rather than matching the
unconditional Receipt type used by Asserts proven. Preserve the distinction
between proofs that depend on axioms and proofs without that dependency.
- Line 1: Add the required MPL-2.0 SPDX identifier as the first line of the new
Agda file, before its existing content.
- Line 136: Update the `discriminates` parameter in the anonymous module so it
uses a refined accessibility relation that can exclude `w-there`, rather than
requiring the impossible contradiction from the original `w-here ≈ w-there`
relation. Keep the original relation for the counterexample and ensure
`receipt-from-check` can be constructed under the refined relation.
Review comments at @QUICKSTART-USER.adoc:
- Line 139: Update the trust-pipeline routing statement in QUICKSTART-USER.adoc
to clarify that both /api/prove and POST /api/verify_parallel call
ProverDispatcher::verify_proof_parallel; state that the verisim feature changes
/api/prove to use the dispatcher with the VeriSimDB writer, not that /api/prove
is exclusive.
Review comments at @scripts/install-proof-toolchains.sh:
- Line 26: Update the fresh-sandbox recipe in install-proof-toolchains.sh to
register the downloaded standard library’s .agda-lib file with Agda, matching
the registration steps used by the CI workflow so echidna-meta.agda-lib can
resolve its standard-library dependency.
- Line 30: Update the commented Agda invocation in the toolchain installation
script to run from the meta-checker directory by adding the directory change
immediately before the command, so the source path resolves correctly.
- Line 23: Update the manual Agda recipe so both PYTHONPATH and PATH are
exported before running agda; replace the single plain-assignment instruction
with separate export instructions so child processes can access both values.
Review comments at @site/docs/api/graphql.adoc:
- Around line 17-19: Update the GraphQL and REST dispatch description to
identify the core-server `/api/*` routes, not the `echidna-rest` listener.
Qualify the distinction: without `verisim`, both GraphQL `verifyProof` and `POST
/api/prove` call `ProverFactory` directly; only the `verisim` branch of `POST
/api/prove` uses `ProverDispatcher`.
Review comments at @src/interfaces/graphql/main.rs:
- Line 51: Update the listener setup in main to handle TcpListener::bind errors
without panicking: propagate the error from main or report it as a configuration
error, preserving the existing behaviour when the address is valid.

The review asks the author to confirm that the external Hypatia consumer accepts an omitted report-format key. This is a verification request, not a defect in the diff.
The inspected evidence does not support a defect. No repository-owned consumer reads this key, and the external consumer's source is not in the checkout. The report records the removal but does not state the consumer's default. Nothing in the inspected material shows that an omitted key causes a failure.
Cargo fmt --check failed in rust-ci: rustfmt prefers breaking after the
'=' when the whole expression fits on the continuation line, which this
one does (95 cols). Matches the existing idiom at src/rust/server.rs:71
and :1043 rather than the chain break I wrote first.

Co-authored-by: arena-agent <297053741+arena-agent@users.noreply.github.com>
Substantive (my claims were wrong or the model was vacuous):
- Receipt.agda: the 'discriminating check' was a parameter that no function
could supply (≈-cross inhabits its domain), so that section proved nothing.
Replaced with a second frame: same worlds, sharper accessibility, a real
receipt, and coarse-yet-sharpened stating the contrast.
- Receipt.agda: proven-with-postulates asserted the same type as proven,
erasing the policy's distinction; it now carries a named axiom.
- ARCHITECTURE.adoc opening invariant still claimed binaries are
integrity-checked before invocation while the detail section says the step
never runs. Reworded; solver identity is now stated as assumed.
- PROOF-STATUS: 'No row is above argued' contradicted R4/R9/R10/R11.
- Integrity.agda: scope stated (digests, not bytes); sharpness consequence
now proved rather than asserted in a comment.
Real defects:
- container/Containerfile healthcheck probed /health; the server serves
/api/health — the container would go unhealthy after start. Same for the
k9 health/readiness probes (there is no /ready route at all).
- agda-meta-checker.yml closure step compared totals and used a
non-recursive glob; now checks each source against its own interface.
- install-proof-toolchains.sh recipe: register the stdlib (a download alone
does not resolve the depend:), and run agda from meta-checker/.
- Missing SPDX headers on the three new Agda modules.
- QUICKSTART: /api/verify_parallel also reaches the dispatcher.
- Stale last-updated/L last-updated metadata; ClampTrust header named a
theorem that does not exist.
Co-authored-by: arena-agent <297053741+arena-agent@users.noreply.github.com>
Addressed in 4b6fd97. Grouped by what actually mattered — the first group is
where my own claims were wrong, which is the part worth reading.
Claims that were wrong (fixed)
Receipt.agda — the "discriminating check" was a (w-here ≈ w-there → ⊥)
parameter, and ≈-cross inhabits that domain, so no caller could ever supply
it and the section proved nothing. Replaced with a second frame: same
worlds, sharper accessibility, a real receipt, plus coarse-yet-sharpened
stating the contrast in one type. That is a stronger result than the vacuous
one, and it is the point of the module.
Receipt.agda — Asserts proven-with-postulates asserted the same
unconditional Receipt as Asserts proven, which erases exactly the
distinction §5 exists to draw. It now carries a named Axiom, with postulates-name-an-axiom as the witness.
Integrity.agda / PROOF-STATUS R9 — the model is digest-level, so
"substituted binary" means "a binary whose digest differs"; content-level
collision resistance is the comparator's ≈d-sound field. Stated in the
module header, in R9, and the sharpness consequence is now proved
(sharpness-blocks-soundness) instead of asserted in a comment.
MetaChecker.agda — "0 postulates, 0 assumptions" conflated the two. --safe rules out postulates; Integrity is genuinely conditional on Hash.≈d-sound. Said so.
ARCHITECTURE.adoc opening invariant contradicted its own detail section:
it claimed binaries are integrity-checked before invocation while §Integrity
says the step never runs. Reworded — solver identity is now stated as
assumed, certificate reproduction keeps its claim.
PROOF-STATUS — "No row in this file is above argued" contradicted the
four rows this PR promotes. Rewritten: four proven, every independent leg
still open, which is what Grade 3 means.
QUICKSTART-USER.adoc — /api/verify_parallel also calls ProverDispatcher::verify_proof_parallel, so /api/prove is not the only
path to the dispatcher.
Real defects (fixed)
container/Containerfile healthcheck probed /health; the server registers /api/health. After this PR's entrypoint.sh fix the container would start
and then go unhealthy. The k9 health_check/readiness_check had the same
problem, and /ready is not a route at all.
agda-meta-checker.yml closure step compared totals and used a
non-recursive src/Echidna/*.agda glob, so a stray interface could offset a
missing module. It now checks each source against its own interface by module
name. (Interfaces live under _build/<version>/agda/, not beside the
sources — verified, not assumed.)
scripts/install-proof-toolchains.sh — the recipe downloaded the stdlib
without registering it (a download alone does not resolve depend:), and
ran agda from the repo root where src/Echidna/... does not resolve.
Missing SPDX headers on all three new .agda modules. The PR checklist
claimed they were present; they were not. Corrected.
docs/ECOSYSTEM-INTEGRATION.adoc and NEUROSYM.a2ml stale last-updated.
ClampTrust.agda header listed a clamp-roundtrip obligation that does not
exist (the theorem is clamp-idempotent) and mis-stated the count.
Not changed, with reasons
DEBT D9's Uninitialized sentence and the missing [source,bash] blocks on
D9/D12: the register's command-per-entry convention is repo-wide and older
than this PR; changing three entries here would make the file inconsistent
rather than consistent. Worth a separate sweep.
ECOSYSTEM-INTEGRATION "loaded by nothing": scoped to this repository, and
the report marks the finding argued for exactly that reason. Leaving the
hedge where it is.

rust-ci / Cargo check + clippy + fmt now passes (a68b601) — the earlier

to this branch.
The CHANGES_REQUESTED review is still standing, so the PR cannot merge until
it is re-reviewed or dismissed.
This command requires write access to the repository. Only users with write or admin permissions can trigger CodeRabbit to commit or create pull requests.
Re-review requested: the findings from the previous review are addressed in 4b6fd97 (see the reply above) and your autofix commits are in 59e88cd and 1283392. The corpus still type-checks after those edits (agda --safe --without-K --cubical-compatible, exit 0), and rust-ci / Cargo check + clippy + fmt is green.
The standing CHANGES_REQUESTED is what blocks the merge; please post an updated review.
Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.
Both cargo-audit jobs on #455 reported the same advisory. Update the
root lock entry to 0.13.5 using the crates.io index checksum. The index
declares identical dependencies for both versions. Verify hosted Cargo
audit and locked build. The fuzz workspace has no pulldown-cmark entry.
Replace repeated Agda and cargo-audit source bootstraps with checksum-verified upstream releases. Audit both lockfiles and update vulnerable dependencies. Reject missing or unselected live prover tests, provision real Chuffed, resolve the explicit Guix package subset, repair canonical reusable callers, and correct proof-model evidence with targeted rejecting controls.
Provide an opt-in, read-only official actions.lock refresh candidate for the published workflow changes; canonical lock verification remains required.
Restore merged-tree type-checking for pull requests that touch meta-checker/.
The Agda job now checks out the pull request head commit (ref: ${{ github.event.pull_request.head.sha || github.sha }}). Before this change, the default checkout for a pull request combined the PR with the current main. That let the type-check cover the merged tree.
The job now type-checks only the PR branch. If main changes a meta-checker/ module that the PR branch lacks, and the PR is incompatible with that change, the job can pass while the merged tree fails. The committed branch ruleset does not require branches to be up to date, so the PR can merge while behind main. The post-merge push run then becomes the only detection point.
Restore pre-merge coverage of the merged tree. Either check out the merge ref for pull requests again, or merge the base branch into the checkout before bash scripts/ci/check-agda.sh runs. A merge-ref checkout can fail when a pull request conflicts with main. Keep that failure visible rather than skipping the type-check.

The assertion at tests/live_prover_suite.rs:162-166 accepts any non-empty string except unknown. It does not check how the string was produced. A version() that returns a fixed identifier passes this check whenever the binary is on PATH. The merge-base ChuffedBackend::version() returned "chuffed" without running the executable. The current implementation runs --help, so that case is fixed at head.
No other exercised assertion rejects a constant response. emit_live_result records success whenever version is Some. A future regression of this kind would pass CI. The file header and the assert_version_reachable comment state that the check confirms the subprocess wiring. The current assertion does not confirm that.
Add a test whose pass condition depends on the executable actually running. Base the condition on an observable effect of the invocation, not on the returned string. Do not compare the returned string with an expected output or token. A constant that matches that output or token would still pass. Keep the existing non-empty check.
Define the invocation for each backend. Chuffed uses --help, SPASS runs with no argument, and the other inspected backends use --version.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
ChuffedBackend::version requires fzn-chuffed --help to exit successfully and print a nonempty line to stdout. A usable binary whose help text goes to stderr, or whose help invocation exits nonzero, will now be reported as unavailable.
Chuffed version checks fail, including the newly required CI smoke check, although the solver can run.
This can occur when: The configured Chuffed executable uses either of those help-output conventions.

Allow scanner artifacts to be overwritten on reruns
When a scanner job uploads its artifacts and then fails the following gate—for example because a critical finding was reported—rerunning failed jobs executes these uploads again within the same workflow run, where panic-attack-toolchain, panic-attack-findings, and the other fixed artifact names already exist. The upload-artifact documentation states that overwrite defaults to false and an existing matching name makes the action fail, so such a rerun cannot become green even if the new scan succeeds. Add overwrite: true to the rerunnable scanner uploads, or use attempt-qualified names and update the downloads accordingly.
The reason will be displayed to describe this comment to others. Learn more.
The source fix is present in head 346a31df421e7dc4972119d71b49684a0e6ffda3: all six actions/upload-artifact steps in static-analysis-gate.yml explicitly set overwrite: true, covering the toolchain, panic findings, Hypatia report, bridge report, raw evidence, and unified findings. Existing artifact names and their download consumers are preserved.
The current Static Analysis Gate still records scanner/evidence failures; this change does not suppress them. A repeated upload within the same run has not been exercised as part of this qualification, so I am leaving this thread open pending that bounded rerun evidence.

Trivial · Exercise the binary with the default address · startup.rs:77-130
The startup tests always set ECHIDNA_GRAPHQL_ADDR, so they do not exercise the default branch in src/interfaces/graphql/main.rs. Testing an extracted default-value helper alone is insufficient because the binary could bypass that helper or use a different default. Add an integration test that removes ECHIDNA_GRAPHQL_ADDR, starts the actual binary, and checks readiness on 127.0.0.1:8082.

Reject failed processes before accepting version output
When a required prover's --version command prints a nonempty diagnostic and exits unsuccessfully, this condition still lets the live gate pass: the migrated Z3, CVC5, Alt-Ergo, Vampire, EProver, GLPK, and MiniZinc version() implementations receive the subprocess status from version_probe::run but discard it and return Ok from the output text. A broken binary or wrapper that prints an error and exits 1 is therefore recorded as reachable; require a successful status in those backends (with explicit exceptions such as SPASS handled separately) before treating the text as identifying output.
…ed on #455) (#459)
## Summary
Stacked on #455, which rewrites the same lines of
`live-provers.yml` and carries the repair for main's current startup
failures. Merge #455 first; GitHub then retargets this PR to `main`.
The T1 provision step ran `apt-get update` before every backend,
including vampire, cvc5, alt-ergo and (with #455) chuffed, which install
from GitHub release assets and never touch apt. On #446 the runner
image's `packages.microsoft.com` source answered 403 twice, so `T1 /
vampire` failed before any test ran ([job
118637174820](https://github.com/hyperpolymath/echidna/actions/runs/39425579312/job/118637174820)).
The re-run passed, so it was the mirror and not the prover.
## Changes
- `live-provers.yml`, T1 provision step: `apt-get update` moves into an
`apt_install` helper. Only the apt-installed backends call it (z3,
eprover, spass, glpk, minizinc). The release-asset backends no longer
depend on the image's apt sources being reachable.
An earlier version of this branch also pinned the T1 Guix job to
`ubuntu-24.04`. I dropped that, because #455 makes the same fix with a
pinned guix version and a running daemon.
## RSR Quality Checklist
### Required
- [x] Tests pass: workflow-only change; the checks below ran on #455's
tree plus this commit
- [x] Code is formatted
- [x] Linter is clean: `actionlint` with shellcheck, exit 0
- [x] No banned language patterns
- [x] No `unsafe` blocks without `// SAFETY:` comments: n/a
- [x] No banned functions: n/a
- [x] SPDX license headers present on all new/modified source files
- [x] No secrets, credentials, or `.env` files included
### As Applicable
- [ ] Docs, deed, roadmap, changelog: n/a (CI provisioning only)
## Testing
Run locally on this tree:
- `actionlint` (with shellcheck) on `live-provers.yml`: clean.
- `scripts/ci/test-issue-regressions.sh` (with mikefarah yq v4): passed.
- `scripts/ci/check-allow-fail-expiry.sh`: 10 units, passed.
- In the provision step, `sudo apt-get` now appears only inside the
helper.
- No `uses:` changed, so `actions.lock` is unaffected.
This PR's own CI is the live test of the T1 matrix on the new step.

Purpose

The original audit, Agda modules and quarantined Logtalk source remain in the repository, including the routing and rule-engine report and the source-bound proof-status ledger.

The preceding head
346a31df421e7dc4972119d71b49684a0e6ffda3has exact-tree receipts: merge checkout c8d1605 has the identical tree d2d7ae58b7016d8a37d754a6618c21b4a3f46195.Both real corpus-hazard ingestion tests ran in those suites. They establish detection of the checked-in Isabelle/Lean hazards, not theorem validity or a severity exemption. The raw Critical findings remain.
The canonical scanner canary at b8dc completed full-history Gitleaks in 43 seconds, Rust secrets in 3 seconds and shell secrets in 4 seconds, measured as whole-job durations.
Remaining gates
Current 3f requires its own qualification. Its real Chapel job now passes export checks, five native-link controls and the Zig bridge build, but the packaged compiler's runtime-layout query still fails. Formatting and two new Sonar findings are being corrected; the existing #416 waiver has not been widened.
Panic Attack PR258 must qualify upstream before consumer adoption. The older scanner correctly reports incomplete coverage, and the fleet deposit must not treat that as a successful scan. The original audit's open semantic proof obligations, current security/quality findings, actual review state and required checks remain distinct from a passing test suite. No live learning or permanent estate-wide closure is claimed.
