Three checks fail on main (2ab7574), so every open PR is red on them. This PR fixes all three. It replaces #467 and #468, which carried the same commits and are now closed.
Check
Cause
Fix (commit)
Dependency audit, rust-ci / Cargo audit
rmcp 3.5.0 (crates/echidna-mcp) has RUSTSEC-2026-0457, -0461 and -0462, published after main last passed
Cargo.lock only: rmcp and rmcp-macros move to 3.9.0, inside the existing "3" requirement (20dc691)
rust-ci / Cargo check + clippy + fmt
cargo fmt --check drift in src/rust/proof_search.rs
cargo fmt, formatting only (17ebbb1)
governance / Validate Hypatia Baseline
Hypatia code_safety/zig_ptr_cast and zig_align_cast are high on the nine @ptrCast(@alignCast(raw)) lines in src/zig_ffi/
A reasoned inline hypatia: allow per rule on each line, with no baseline entry (f48fe0a)
Every one of those casts gets a callback's own *@This() back from the type-erased *anyopaque it was registered with: runtime_owner.Work.context, or a std.mem.Allocator vtable's ptr. So each cast restores the pointer's original type and alignment. Order of preference: fix > inline directive > .hypatia-ignore > baseline.
Changes
Cargo.lock: rmcp and rmcp-macros 3.5.0 → 3.9.0.
src/rust/proof_search.rs: rustfmt only.
src/zig_ffi/chapel_bridge.zig and src/zig_ffi/runtime_owner.zig: comments only.
RSR Quality Checklist
Required
Code is formatted: cargo fmt --all -- --check passes.
cargo check -p echidna-mcp --locked: passes. The crate has no tests.
Hypatia: the scanner could not be built here because hex.pm is unreachable. I simulated its suppression logic instead: directive_re and ScannerSuppression.inline_allowed?/4 at hypatia 82396d81, the CI pin. That reports 18 unsuppressed findings on main (9 casts × 2 rules) and 0 on this branch.
Zig isn't available here. The Zig change is comments only, so it can't affect the build.
Checks still red, and not caused by this PR
Deposit findings for gitbot-fleet, Isabelle/HOL, scan / scan: also red on main.
What failed:provers::chuffed::tests::version_requires_a_successful_help_response_and_closed_stdin exited with Text file busy (os error 26).
Root cause:ETXTBSY. A test writes its fake prover script and then executes it. If another test thread forks in between, the child inherits the still-open write descriptor, and the kernel refuses to execute the file while it is open for writing. The same pattern exists in the fixtures in chuffed.rs, gpuverify.rs, faial.rs, version_probe.rs and proof_search.rs.
What I did: re-ran the job once to confirm the failure is intermittent.
Proposed fix (separate PR): a shared test helper that retries the spawn on io::ErrorKind::ExecutableFileBusy.
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.

Full details: Title check
Explanation
The title names the fix and the three CI failures it addresses (rmcp RustSec advisories, rustfmt, Hypatia Zig casts). The PR changes match each part: Cargo.lock bumps rmcp to 3.9.0, proof_search.rs is reformatted, and the Zig files gain suppression comments. The title is specific and concise, though it lists three items rather than one main change. This is a PASS.
Full details: Description check
Explanation
The description follows the repository template in substance. It has a Summary section, a Changes section listing each modified file, a RSR Quality Checklist with the required items marked, and a Testing section with detailed commands and results. It also explains the Hypatia scanner limitation and lists CI checks still failing on main. Some template items are not addressed, including the SPDX header check, the ABI/FFI check, and the CHANGELOG item. The Screenshots section is absent, which is acceptable because it is marked as applicable only when relevant. The Required checklist omits the banned-language, unsafe-block, banned-function, SPDX and secrets items, and the Testing and Summary sections do not link related issues with 'Closes #N'. These gaps are non-critical, so the check passes.
Full details: Docstring Coverage
Explanation
Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 1 files. (2 skipped: 2 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

`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.

Claude-Session: https://claude.ai/code/session_019a95kk88TZ1iegsBK3kox3
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).

Port of the rmcp lockfile change from #465 so this docs PR's dependency
audit is not red for a reason unrelated to it. Regenerated with
`cargo update -p rmcp --precise 3.9.0`; the windows-sys lines are
resolver output, identical to #465. No-op once #465 lands.
Verified locally: scripts/ci/audit-dependencies.sh passes for both
lockfiles; `cargo check -p echidna-mcp` builds.

Dependency audit fails on every PR, this one included, because rmcp 3.5.0
(crates/echidna-mcp) has three advisories, the newest published 2026-11-05,
after main last passed. Ported from #465 so this PR does
not wait on it: `cargo update -p rmcp --precise 3.9.0` with the pinned 1.99.0
toolchain, inside the existing "3" requirement. The other lock lines are the
resolver re-unifying around rmcp 3.9.0's new sha2/libc dependencies. The
resulting Cargo.lock is byte-identical to #465's, so whichever merges first
leaves the other a no-op.
scripts/ci/audit-dependencies.sh with cargo-audit 0.22.2: Cargo.lock and
fuzz/Cargo.lock both PASSED. cargo check -p echidna-mcp --locked: passes.

Validate Hypatia Baseline fails on this PR. It reports four unannotated
zig_ptr_cast/zig_align_cast findings in src/zig_ffi/, which are also red
on main and unrelated to this docs PR. This ports #465's fix unchanged:
- inline `hypatia: allow` annotations with a justification on each cast
(comments only; the code is unchanged);
- its rustfmt reflow of src/rust/proof_search.rs.
Both become no-ops once #465 lands. `rustfmt --check` passes on

…ts (#487)
## Problem
`rust-ci / Cargo test` failed intermittently with:
```
provers::chuffed::tests::version_rejects_failed_empty_or_stderr_only_help
Failed to execute fzn-chuffed --help: Text file busy (os error 26)
```
It failed on #470, whose diff contains no Rust, and earlier in llvm-cov.
The cause is a real race, not a flake. Four fixtures (chuffed, faial,
gpuverify and version_probe) each write a shell script and execute it at
once. If another test thread forks while the write descriptor is still
open, the child keeps a copy of it until it reaches `exec` (Rust opens
files close-on-exec). While any writer exists, the kernel refuses to
execute the file with `ETXTBSY`.
## Fix
New test-only helper, `provers::test_fixture::write_executable`
(`cfg(all(test, unix))`). It:
1. creates the script with mode `0700` and closes it;
2. runs it with a sentinel argument until the kernel accepts the `exec`
(up to 2 s, then it panics).
After one successful `exec`, no writer remains and no later fork can
inherit one, so the test's own spawn cannot hit `ETXTBSY`. Every fixture
script exits 64 on an unexpected argument, so the probe never runs a
fixture body. The four fixtures now use the helper.
The PR also carries #465's rustfmt fix to `proof_search.rs`,
byte-identical to it, so `cargo fmt --check` is green here as well.
## Checks run locally
- `cargo test --lib -- provers::chuffed provers::faial
provers::gpuverify provers::version_probe`: 58 passed.
- `cargo clippy --lib --tests -- -D warnings`: clean.
- `cargo fmt --check`: clean.
Once this is open, I'll port it into the open PRs that hit the race
(starting with #470).

…pre-split goldens (#483)
## Summary
This is the W0 "split" lane. It is stacked on #475, which carries the
gate it is checked against. Three hotspot files are broken into modules
by area. Behaviour is held fixed by goldens captured on the pre-split
tree, and W0 exit check 5 compares them. Nothing is renamed or
redesigned.
## Changes
- **Goldens first** (535274c). `tests/golden/hotspot/` holds 27 files
captured before any move: every route, the router composition, and
`--help` for each CLI command and subcommand.
`scripts/gates/hotspot-goldens.sh` regenerates them and compares.
- **`src/rust/server.rs` →
`server/{mod,agent,prove,search,session,status,ui,verify}.rs`**
(a2fb862). Handlers move by route family. `mod.rs` keeps router
composition and shared state.
- **`src/rust/main.rs` →
`cli/{args,util,prove,verify,search,session,provers,lexicon,corpus,design}.rs`**
(ee2ed98). `main.rs` keeps only parsing, tracing set-up and dispatch;
`cli/mod.rs` re-exports the command functions.
- **`Justfile` → `just/*.just`** (9444837). There are 14 files, one per
area, pulled in by `import`. The contractile import stays last. Recipe
names and bodies are unchanged; `just --list` matches before and after.
- **Merged from #475's base:** the #465 fix for the red checks on `main`
(rmcp 3.9.0, rustfmt on `proof_search.rs`, and the Zig-cast
annotations).
## RSR Quality Checklist
### Required
- [x] Tests pass. W0 check 5 (hotspot goldens) passes, and so does
`cargo check --bins` after the merge. I have not run the full `just
test` on this branch: disk here is limited. This PR's CI runs it.
- [x] Code is formatted (`cargo fmt --all -- --check` is clean).
- [x] Linter is clean (`cargo clippy` was clean when the split landed).
- [x] No banned language patterns.
- [x] No new `unsafe`.
- [x] No banned functions.
- [x] SPDX headers on all new files.
- [x] No secrets.
### As Applicable
- [ ] Documentation: `CLAUDE.md`'s structure tree still lists
`server.rs` and `main.rs`. That reconcile is reserved for the rulings
lane (#58), so this PR does not edit `CLAUDE.md`.
## Testing
- `bash scripts/gates/hotspot-goldens.sh check` exits 0: routes, router
composition and CLI help are byte-identical to the pre-split capture.
- `cargo check --bins` and `cargo fmt --all -- --check` pass on the
merged head.
- Already broken on the pre-split tree, and not changed here: `echidna
corpus import-octads --help` panics (exit 101). It has its own
follow-up.

…ource, playground template owner (#473)
## Summary
Since #458, echidna's workflows run again, which exposed small reds on
main and on every PR. This PR fixes them. Each was reproduced locally
first, then shown fixed with the same tool CI uses.
## Changes
- **`src/rust/proof_search.rs`: `cargo fmt`** with the repo's pinned
1.99.0 toolchain.
- Rust CI on main (run 42351375993) fails only at the fmt step.
- This is the only file the workspace-wide `cargo fmt --all` touches.
- **`Cargo.lock`: `rmcp` and `rmcp-macros` 3.5.0 → 3.9.0** for
RUSTSEC-2026-0457, -0461 and -0462. The newest was published 2026-11-05,
after main last passed `Dependency audit`.
- Ported from #465 so this PR doesn't wait on it: `cargo update -p rmcp
--precise 3.9.0`, inside the existing `"3"` requirement.
- The resulting `Cargo.lock` and `proof_search.rs` are byte-identical to
#465's, so whichever merges first leaves the other a no-op.
- **`.github/workflows/workflow-linter.yml`: rename `authority_sha` →
`standards_rev`.**
- gitleaks `generic-api-key` read the 40-hex commit id as a key only
because the variable name contains "auth".
- The fix is at the source, so no `.gitleaks.toml` entry is added. An
earlier commit on this branch added one, and `Exemption ratchet`
rejected the ledger growth (2 → 3). That entry is gone.
- **`echidna-playground/ci-templates/governance.yml`: the never-run
template now names `metadatastician/standards`.** It uses the same pin
as root's live `governance.yml` (`a797d30`) instead of the old owner at
`861b5e9`.
## RSR Quality Checklist
### Required
- [x] Tests pass:
- `cargo fmt --all -- --check` passes;
- `cargo check -p echidna-mcp --locked` passes against rmcp 3.9.0 (the
crate has no tests).
- [x] Code is formatted: `cargo fmt --all -- --check` passes.
- [x] Linter is clean: actionlint 1.7.7 reports 0 findings on both
workflow files.
- [x] No banned language patterns
- [x] No `unsafe` blocks: none added
- [x] No banned functions: none
- [x] SPDX license headers present: unchanged
- [x] No secrets, credentials, or `.env` files included
### As Applicable
Nothing in this list applies.
## Testing
**gitleaks.** CI-pinned gitleaks 8.18.4 (checksum-verified), with the
estate baseline staged at the root exactly as
`secret-scanner-reusable.yml` stages it:
| Tree | Findings |
|---|---|
| old name `authority_sha`, no `.gitleaks.toml` entry | 1:
`generic-api-key` at `workflow-linter.yml:80` |
| this branch (`standards_rev`, no entry) | 0 |
| this branch, plus a planted `api_token=ghp_…` beside it | 1: the
plant, so it is still detected |
**Dependency audit.** `scripts/ci/audit-dependencies.sh` with
cargo-audit 0.22.2:
- before: `Cargo.lock: FAILED`, with the three rmcp advisories;
- after: `Cargo.lock` and `fuzz/Cargo.lock` both `PASSED`.
**Rust CI.** I reproduced the fmt failure locally on main with toolchain
1.99.0; after this change `cargo fmt --all -- --check` passes.
## Checks red here, and not caused by this PR
- **`Static Analysis / panic-attack assail`** has been red on main since
#455. Two causes:
- The pinned scanner can't finish a scan of this tree, which
#478 fixes.
- After that, the gate blocks on two deliberate `sorry` detector
fixtures, which #480 handles together with
hyperpolymath/panic-attack#278.
## Observed, not changed here
- **`mirror.yml` is back on the pre-transfer pin `3c00687`.**
- #455's merge restored it, with its old comment.
- Main now pins standards at three SHAs: governance `a797d30`; hypatia,
scorecard and spark `d3e4b48`; mirror `3c00687`.
- The lock still closes, and lock-sync and coordinates pass. But
`relock-standards-pin.sh` refuses mixed pins, so the next estate repin
will stop here until mirror moves too.
- **Mirror failures on main are forge configuration, not code.** The
disroot, gitea and sourcehut jobs fail "Verify … SSH host" against the
repo variables `*_SSH_FINGERPRINT`, and the bitbucket push fails.

…eds two small kernels (#477)
## Summary
The 2026-11-09 proof audit found two defects in `compute_trust_level`.
Both were present identically in `src/rust/verification/confidence.rs`
and in its copy in `crates/echidna-core-creusot`, and no proof in any
prover caught either:
- **Level 4** fired on `certificate_verified` without `has_certificate`.
- **Level 5** checked only the producing prover's kernel class, never
the confirmers'. One small-kernel prover plus an SMT confirmer scored
Level 5.
The owner ruled: fix at source, keep one kernel, and add contracts. This
PR does that.
## Changes
**Fixed in the kernel crate (`echidna_core::trust`).**
- From Level 3 up, a certificate counts only when it was produced *and*
verified.
- Level 5 needs two or more small-kernel confirmations. These come from
a new `TrustFactors` input, `small_kernel_confirmations`: how many of
the confirming provers are small-kernel systems with a verified
certificate, the producing prover included.
- The value is read as at most `confirming_provers`.
- It is `#[serde(default)]` = 0, so a caller that cannot vouch for its
confirmers never reaches Level 5.
**One kernel, not two.** `confidence.rs` re-exports the kernel's
`TrustLevel` and delegates `compute_trust_level` to it. It keeps its
`ProverKind`-shaped `TrustFactors`.
**Contracts (TK-4, TK-5).** They are stated as Creusot `ensures` on the
kernel:
- TK-4: Level 4 and above imply a small kernel, `has_certificate` and
`certificate_verified`.
- TK-5: Level 5 implies `small_kernel_confirmations >= 2` and
`confirming_provers >= 2`.
They are checked on stable Rust over every input with counts 0..=4:
TK-4, TK-5, and TK-6, which says more evidence never lowers the level.
There are also regression tests for both defects.
**Retired.** `verification/proofs/idris2/TrustKernelMonotonicity.idr`.
It dropped `has_certificate` and proved the defective Level 5 rule as a
property. Under PROOF-POLICY §1, Rust behaviour is verified on the code,
not restated in Idris.
**Ledgers.**
- PROOF-STATUS R1 now records TK-4/TK-5 as `tested-only`, with Creusot
not yet discharged and Verus not yet applied, each with its scope. R1
stays `open`.
- PROOF-NEEDS marks the Idris row retired.
- CHANGELOG notes the behaviour change.
**A departure from the ruling's wording, reported rather than
absorbed.** The selector option said "Level 5 implies every confirming
prover is small-kernel". This PR instead requires at least two
small-kernel confirmations. Requiring *every* confirmer to be
small-kernel would let one extra SMT agreement lower a result from Level
5 to Level 4, so trust would no longer be monotone in evidence. The
count also matches the Level 5 definition already in the code:
"cross-checked by 2+ independent small-kernel systems".
**Shipped behaviour.** The three dispatch paths pass 0 for the new
input. They already reported no certificate, so their results do not
change.
## RSR Quality Checklist
### Required
- [x] **Tests pass:**
- `cargo test --lib verification`: 106 passed.

- `echidna-core`: 18 passed.
- The 8 integration suites that build `TrustFactors` (aspect,
concurrency, e2e_prover, neural_property, p2p_property,
panic_attack_props, property, security_aspect): 203 passed.
- [x] **Formatted:** the files changed here are `rustfmt`-clean.
`src/rust/proof_search.rs` drift is main's and is fixed by #465.
- [x] **Linter is clean:** `cargo clippy --locked --all-targets -p
echidna-core-creusot -p echidna -- -D warnings` passes.
- [x] No `unsafe`, no banned functions, no secrets.
### As Applicable
- [x] `CHANGELOG` updated.
- [x] Documentation updated: PROOF-STATUS R1 and PROOF-NEEDS.
## Testing
- **Mutation check:** with the old Level 4/5 logic put back into the
kernel, three of the new tests fail: `tk4`, `tk5` and the regression
test.
- **What the tests show:** the counts 0..=4 cover every case only
because the rule reads counts through `>= 2` and a minimum. That
coverage is argued, not mechanised, which is why the status is
`tested-only`.
- **Not run:** Creusot and Verus. Wiring Creusot (a current nightly,
`creusot-contracts`, Why3) is a separate item, and there wasn't disk
space for it in this sandbox.
- **Still divergent:** the Lean `ConfidenceLattice` model and the Agda
`Dispatch.compute-trust` model describe the old rule. Under the owner's
strict §1 ruling they are engineering models that move to Creusot/Verus.
That reclassification is the next PR.
