feat(assail): route languages through a tested table; retire the vacuous PA1 - #282
analyzer.rs: the dispatch in analyze_inner now matches on route(file_lang). So the table is the code that runs, not a model of it. Only the match arm heads changed, and so did the cross-language guard.
src/types.rs: adds Language::ALL (52 variants). An exhaustive ordinal test keeps it complete.
Claims and how they are tested (status TESTED)
Each test was seen to fail on a planted fault.
Claim
Test
Planted fault it caught
(a) Every language analyzer is reached
every_language_analyzer_is_reached
an unrouted analyze_chapel
(b) No language falls back to the generic analyzer while a dedicated one exists
(c) Cross-language checks run exactly on non-configuration content
cross_language_checks_run_exactly_off_configuration (a Justfile plus main.lua, end to end)
runs_cross_language forced to true
(d) The README's language counts match the table
readme_language_counts_match_the_table
the README's stale 49
Routing is not coverage. Language::Unknown goes to InputAdapter, and a file there with no adapter is marked unsupported and skipped. PROOF-NEEDS.adoc says so.
Retired
PatternCompleteness.idr, for three reasons:
It was vacuous: GenericAnalyzer inhabited its witness for every language.
It was stale: it covered 50 of 52 languages.
It was partly false: it said cross-language checks always run.
The ipkg now lists 4 modules.
The pa1 entry in 0-AI-MANIFEST.a2ml is deleted. This is a deletion only.
The README count: 49 → 51 supported languages, in the badge, the capabilities list and the summary.
Found, not fixed here (recorded in PROOF-NEEDS open obligations)
Unquoted http:// URLs are missed by the cross-language check.analyze_cross_language strips // comments from every file. That also cuts curl http://host in shell and Justfile recipes. The fix is a follow-up stacked PR.
Prove PA1 (a)–(c) with Creusot/Pearlite and Verus.
Verification
cargo fmt --check.
cargo clippy -D warnings, with all features and with default features.
cargo test: 789 passed.
The self-scan is clean.
idris2 --typecheck src/abi/panic-attack-abi.ipkg (Idris2 0.7.0): exit 0, no Error: line.
…ous PA1
PA1 was an Idris2 model of the analyzer dispatch whose theorem could not
fail: `GenericAnalyzer : HasAnalyzer lang` inhabited its witness for every
language. It was also stale (50 of 52 languages) and partly false (it said
cross-language checks always run; they are skipped for configuration).
The routing is now real code with claims that can fail:
- src/assail/routing.rs: `route(Language) -> Route`,
`Route::analyzer()`, and `runs_cross_language(is_configuration)`.
`analyze_inner` matches on `route(file_lang)` and calls
`runs_cross_language`. Only the arm heads changed; every arm body is
byte-identical. `route` and the dispatch are exhaustive with no
wildcard (Chapel, the one language without a dedicated analyzer, is
routed to Generic explicitly).
- src/types.rs: `Language::ALL` (52 variants), kept complete by an
exhaustive `ordinal` match test, following WeakPointCategory::ALL.
- Tests, exhaustive over Language::ALL:
(a) every language analyzer in analyzer.rs is reached;
(b) no language falls back to analyze_generic while a dedicated
analyzer for it exists;
(c) cross-language checks run exactly off configuration, and on
scripts embedded in it (Justfile + Lua scan, end to end);
(d) README's language counts equal the supported count.
Each was seen to fail on a planted fault.
- README: 49 -> 51 languages (badge, capabilities, summary); (d) caught
the drift. C and Php were added after the count was written.
- PatternCompleteness.idr removed from src/abi and the ipkg; PROOF-NEEDS,
EXPLAINME, PROOF-PROGRAMME and the 0-AI-MANIFEST entry updated. PA1's
status is TESTED; the Creusot/Pearlite and Verus proof is OPEN.
Found while testing (c), recorded as an open obligation, not fixed here:
the cross-language check strips `//` comments before matching, which
also cuts unquoted `http://` URLs (shell, Justfile recipes).
Checked: cargo fmt; clippy -D warnings with all and default features;
cargo test --all-features (789 passed, 0 failed); the Idris2 package
type-checks (4 modules); panic-attack's self-scan reports nothing new.

Lean and Isabelle scans now report each matching sorry occurrence separately, with line-specific findings. Inline suppression markers are also recognised in ML-family files.
Added an experimental report-publishing capability; it is not yet connected to a command.
Bug Fixes
KYAML output checks write access before proceeding, helping prevent partial changes when an output cannot be written.
Documentation
Updated supported-language information and added documentation on report publishing and verification results.
The pull request adds exhaustive analyzer routing and line-anchored proof findings, updates Idris2 ABI proofs and their CI checks, introduces an experimental generation-based publisher with model checks and stress tooling, and adds pre-write access checks for KYAML outputs.
The new route table maps languages to analyzers, and analyze_inner dispatches through routes. Tests check route coverage, cross-language conditions, and README language counts. Proof-status material replaces the previous PA1 completeness claims with routing claims.
Line-anchored proof findings and suppression src/assail/analyzer.rs, src/assail/mod.rs, src/comment_marker.rs
Lean and Isabelle sorry occurrences now produce individual line-anchored findings. Comment and prose stripping preserves newlines, and suppression markers support start-of-line (* ... *) forms.
The stripping proof moves to src/abi/Stripping.idr. It proves clean-input preservation, clean output, and idempotence, and includes closed-term sanity checks.
ABI module checks and CI gate .github/workflows/proven-tests.yml, scripts/ci/check-idris-abi.sh, src/abi/panic-attack-abi.ipkg, CHANGELOG.adoc, PROOF-NEEDS.adoc, PROOF-PROGRAMME.adoc
The workflow replaces the former package-based job with an idris-abi job. The checker validates Idris2 version, module paths, totality declarations, and listed escape hatches before type-checking modules.
Generation-based publishing
Layer / File(s)
Summary
Generation storage and publication src/publish.rs, src/lib.rs
The experimental module writes report sets into generation directories, publishes a CURRENT manifest, supports digest-verified consistent reads, updates optional mirrors, and collects old generations.
Protocol state models tests/publish_model.rs, verification/proofs/tlaplus/GenerationPublish.tla
The explicit-state and TLA+ models represent writer interleavings, reader retries, crashes, mirrors, collection, and protocol mutants.
Model-check runs and recorded results verification/proofs/tlaplus/*.cfg, verification/proofs/tlaplus/check.sh, .github/workflows/verify.yml, docs/design/GENERATION-PUBLISH.adoc, PROOF-NEEDS.adoc
The TLC configurations check expected outcomes. The workflow runs them, and the design and proof-status documents record model bounds, results, limitations, and open obligations.
Publication stress and benchmark harness examples/publish_stress.rs
The harness compares in-place, per-file, and generation publication in race and crash trials, and reports timing percentiles and maxima.
KYAML output preflight

Summary
Pre-write access checks and tests src/main.rs, tests/coverage_php_tests.rs, CHANGELOG.adoc
KYAML output paths are checked for write access before output starts. Tests cover unwritable copies and directories, including whether existing reports remain unchanged.

RUSTSEC-2026-0441 marks `pin-utils` unmaintained; its upstream
repository was archived on 2026-10-01. On `main`, `cargo audit` reports
it through `futures-util` 0.3.31.
`futures-util` 0.3.32 and later no longer depend on `pin-utils`. This
runs `cargo update -p futures-util`, which:
- moves `futures-core`, `futures-macro`, `futures-task` and
`futures-util` from 0.3.31 to 0.3.34;
- removes `pin-utils` from the lockfile.
Only `Cargo.lock` changes.
## Path in
`futures-util` reaches the build two ways:
- through the GUI's accessibility chain: `eframe` → `egui-winit` →
`accesskit_winit` → `accesskit_unix`;
- through `js-sys`.
## Verification
- `cargo audit` exits 0. Its warnings drop from 5 to 4. The remaining
four are the upstream-blocked unmaintained advisories, W1 and W2 in
`docs/UPSTREAM-DEPENDENCY-WATCH.adoc` in hyperpolymath/standards.
- `cargo clippy --all-features --all-targets -- -D warnings` passes.
- `cargo test --all-features` passes, including the 531-test main suite.
- `futures-util` 0.3.34 declares `rust-version` 1.71, below this crate's
1.90.

…ing the report (#274)
## Problem
Codex raised this on #264 after it merged. The
`--output-format kyaml` preflight looks each output up, but lookup does
not show that a path can be written. The run then replaces `report.json`
and only afterwards fails on the copy, leaving the new report beside
stale companions. Two inputs trigger this:
- a read-only `report.kyaml` or `report.attestation.json`;
- a directory the caller cannot create files in.
The preflight is meant to be all-or-nothing, and this breaks it.
## Change
- `kyaml_copy_path` now opens each output for writing during the
preflight, without truncating it. An absent output is created and then
removed again.
- The kernel makes the decision, so ACLs and ownership count, not only
mode bits.
- The CHANGELOG `[Unreleased]` entry for the KYAML copy notes this.
## Validation
Two new tests in `tests/coverage_php_tests.rs`: a read-only copy, and an
attested run into an unwritable directory. Each checks that the run
fails with "nothing was written" and that the old report is still there.
- Run as `nobody`, both **fail without the fix** and pass with it. All
13 `kyaml_output_format` tests pass.
- Root ignores permission bits, so as root the two tests detect that and
skip. GitHub runners run unprivileged, so CI exercises them.
- `cargo fmt --check` and `cargo clippy --all-targets -- -D warnings`
are clean, and `cargo test` passes all 24 suites.
Not covered here: the same problem in plain JSON mode with `--attest`
(report plus sidecar), which has never had a preflight. That is on the
follow-up list, and the planned generation-directory publish would close
it for every mode.

…t stripping (#281)
## Problem
`PROOF-NEEDS.adoc` marks panic-attack's Idris2 ABI proofs ✅, but no CI
job ever type-checked `src/abi/`. With Idris2 0.7.0, **none of the five
modules checked as committed**:
| Module | On main |
|---|---|
| all five | module name `PanicAttack.ABI.*` does not match the flat
path `src/abi/*.idr` |
| `Types.idr` | parse error at line 46; `Ord Severity` without `Eq
Severity` |
| `Stripping.idr` | stray `\|\|\|` block at line 222;
**`stripLineCommentsIdempotent` does not type-check** (unsolved
constraint in the `//` case; `decEq` not imported) |
| `PatternCompleteness`, `ClassificationSoundness`,
`AttestationUnforgeability` | check once staged at the right module path
|
## Change
- **`scripts/ci/check-idris-abi.sh`**:
- stages a module-path view of the unchanged files as symlinks, so the
bytes checked are the committed bytes;
- runs `idris2 --check` on each module;
- fails on any type error, a missing `%default total`, or `believe_me`,
`assert_total`, `assert_smaller`, `postulate` or `idris_crash` in code.
- **`proven-tests.yml`, new `idris-abi` job (blocking, every PR)**:
- builds Idris2 from the `v0.7.0` tag, checking commit `27780073…`;
- caches the build and runs the script;
- records a PROOF-POLICY §6 deviation, because the Guix manifest and
container lack Idris2.
The workflow header explains why this departs from its "no Idris2
bootstrap on PRs" rule: a claim needs a receipt on every change, and the
cache keeps it fast.
- **`Stripping.idr`, re-proved:**
- `stripIsIdOnClean`: stripping is the identity on text with no `//`.
- `stripIsClean` / `bodyIsClean`: the strippers' output has no `//`, by
mutual induction.
- `stripLineCommentsIdempotent` and `bodyIsFixedPoint` follow.
- The strippers are restated with explicit `Bool` steps, which can be
reasoned about.
- **`Types.idr`:** adds the missing `Eq Severity` and fixes the `LangId`
declaration syntax.
- **`PROOF-NEEDS.adoc`, `EXPLAINME.adoc`, `CHANGELOG.adoc`:** state that
the earlier ✅ claims had no receipt, and name the new one.
## Validation (Idris2 0.7.0, built here from the same tag)
- `scripts/ci/check-idris-abi.sh` passes all 5 modules.
- The gate fails both ways:
- on main's files: `Stripping` and `Types` FAIL;
- on a planted `believe_me`: FAIL.
- Stripping mutant (blank with `/` instead of a space): rejected at
`bodyStepIsClean` and the sanity tests.
- Differential run of the restated strippers against the original
definitions: every string of length ≤ 9 over `{/, x, \n}` (29,524
inputs), **0 mismatches** and 0 non-idempotent outputs.
- Nine closed sanity theorems check by evaluation.
- `actionlint` 1.7.7 is clean, and `asciidoctor --failure-level=WARN` is
clean on the edited `.adoc` files.
## Departure from the agreed plan
The agreed option was "CI job + ipkg". I did not add an `.ipkg`, because
one needs the files moved to `src/abi/PanicAttack/ABI/`. Their paths are
cited in about 13 places, including legacy A2ML metadata that agents may
not edit. The staging script gives the same check with no moves. Moving
the files plus an `.ipkg` is the cleaner long-term layout and is a
natural follow-up.

…th experiments and a model check (#275)
**Prototype, kept as a draft until the maintainer decides the open
design questions.** Nothing calls it yet.
## Why
On #264 the maintainer chose to replace
per-file output writes with a **generation-directory publish**. This
prototype tests that design on evidence first.
The publish is meant to close three gaps that exist in every output mode
today:
- **Check-then-write race:** a symbolic link swapped in between the
preflight check and the write.
- **Partial files after a crash.**
- **Interleaving between concurrent runs.**
## What is here
### `src/publish.rs`
For a report `D/S.json`, the layout is:
- `D/S.gen/<id>/`: one complete generation per directory.
- `D/S.gen/CURRENT`: a JCS manifest naming the current generation and
the SHA-256 of each of its files.
- Mirrors at `D/S.json` and the other output names: hard links into the
current generation, with copies where linking fails.
A publish runs in this order:
1. Write the generation into `<id>.partial/`, syncing each file.
2. Rename it to `<id>`.
3. Under a `File::lock`:
- refuse if `CURRENT` names a newer generation (ids sort by run start);
- otherwise replace `CURRENT` by temp file and rename;
- refresh the mirrors;
- collect old generations (default: keep 1 older).
Readers take no lock. When the generation `CURRENT` named has been
collected, they retry from `CURRENT`.
### `examples/publish_stress.rs`
Compares three strategies: `inplace` (`fs::write`, as on main),
`perfile` (rename each file) and `genset` (this prototype). It runs a
multi-process race, kill -9 crash trials and a latency bench.
### `tests/publish_model.rs`
An exhaustive explicit-state check of the protocol, reported as
**TESTED** with these bounds:
- up to 3 writers and 1 reader, 2 files;
- a crash at every writer step;
- garbage collection of crashed **and live** writers' partial
generations;
- 13,427 states at most.
Results:
- **P1–P3 hold:** `CURRENT` names only complete generations, it never
moves backwards, and manifest readers never fail or return a partial
set.
- **P4 fails, as expected:** after a crash the mirrors can be torn.
- **Three deliberate mutants are each caught**, showing that the
invariants are not trivially true.
## Measured on Linux 6.18, ext4, 4 cores
| | inplace | perfile | genset (mirrors) | genset (manifest) |
|---|---|---|---|---|
| race, 3 writers × 150 + readers: partial reads | 7931 / 8424 | 0 /
3209 | 0 / 6058 | **0 / 2500** |
| race: torn sets | 182 | 3008 | 67 | **0** |
| kill -9, 300 trials: partial / torn left behind | 176 / 13 | 0 / 155 |
0 / 3 | **0 / 0** |
| 100 races: torn final state | 0 | 7 | 0 | **0** |
| p50 latency, 1 KiB / 256 KiB / 4 MiB | 0.27 / 1.0 / 12.5 ms | 1.2 /
3.2 / 23.8 ms | 2.7 / 4.6 / 33.7 ms | |
Defects the experiments found, each fixed here with a test that fails
without the fix:
- GC raced a writer renaming its own `.partial` directory, so a writer
crashed with NotFound in 1 of 40 races.
- A reader could lose a generation to GC: 1 in 2,500 reads. It now
retries, and was 0 in about 11,200 reads afterwards.
## Open before this can be wired
- **Mirrors torn after a crash** (P4). The options are to document it,
to use one `current` symlink pointer (crash-consistent on Unix), or to
drop the mirrors.
- **Proof legs** under `PROOF-POLICY` §1.2 and §4:
- a TLA+ spec checked by TLC (the policy's worked exception), which was
not runnable in this session;
- Creusot/Pearlite and Verus for the pure selection logic, still OPEN.
- **Other questions:**
- the generation id format (UUIDv7 or v8 per the estate ID policy);
- Windows behaviour (no Windows run yet);
- power-loss durability (fsync ordering is not tested; kill -9 tests
process crashes only);
- what a replacement keeps: ACLs, xattrs, labels and ownership.

…ers apply (#278)
## Why
Lean and Isabelle `sorry` produced one ProofDrift finding per file, with
a count and `line: None`. The inline `panic-attack: accepted` pass only
runs on findings that carry a line. So the only way to record an audited
`sorry` was the A2ML classification registry, which is retired
estate-wide and matches a whole file and category.
That left hyperpolymath/echidna's static analysis gate red with no
supported way out. Its corpus adapters keep deliberate detector
fixtures: a `sorry` they must flag. hyperpolymath/echidna#478 bumps
echidna to the scanner commit that can complete coverage, and these two
fixtures are then its only Critical findings.
## What
- **One finding per occurrence.** Each Lean or Isabelle `sorry` is its
own Critical ProofDrift finding with its `line`. `stats.unsafe_blocks`
counts the same as before. A severity gate's pass/fail is unchanged,
though a file with N `sorry` now contributes N findings.
- **Position-preserving strippers.** `strip_proof_comments` and
`strip_isabelle_prose` now keep every newline of a removed comment or
prose span, and the line-comment pass splits on `'\n'` instead of
`lines()`. Line numbers taken from the stripped text are therefore line
numbers in the file (cf. #114). The new `occurrence_lines` maps matches
to 1-indexed lines.
- **`(*` marker leader**, recognised at the start of a line only, for
Isabelle, Coq/Rocq, OCaml, SML and F*. A trailing `*)` is dropped from
the reason. Mid-line `(*` is excluded because it is also a C dereference
or a Python splat.
- **Fix: markers when the scan root is not the working directory.**
Locations are relative to the scan root, but the marker pass read them
relative to the process working directory. So `assail <dir>` run from
anywhere else silently ignored every inline marker, in all languages. It
now resolves against the scan root first and falls back to the working
directory.
## Evidence
- `cargo test --features http`: **791 passed, 0 failed**. `cargo clippy
--features http --all-targets`: **0 warnings**. `cargo fmt` is clean.
- New tests:
- a `proptest` that both strippers preserve every newline, over
generated inputs built from comment, prose and cartouche tokens
(including unterminated blocks and `\r\n`);
- unit tests for `occurrence_lines`, for a `sorry` after multi-line
comments and prose, and for the new leader (start-of-line only,
previous-line suppression);
- an end-to-end `analyze()` over a temp dir: one marked and one unmarked
`sorry` per language, behind multi-line comments and prose. It runs from
the crate root, so it also covers the root resolution.
- Mutants, each **killed** by the new tests:
| Mutant | Result |
|---|---|
| markers-read-cwd-only | killed |
| block-drops-newlines | killed |
| prose-drops-newlines | killed |
| no-ml-leader | killed |
| unterminated-drops-lines | killed |
- **Against echidna `main`**, with its two fixtures annotated (`(*
panic-attack: accepted (…) *)` above the Isabelle `sorry`, `--
panic-attack: accepted (…)` above the Lean one), scanned from `/tmp`:
- both findings are suppressed at `Smoke.thy:21` and `algebra.lean:11`;
- echidna's own `static-analysis-evidence.sh scan` + `gate` passes:
`status: ran`, exit 0, `critical: 0`, total 109, which is 111 minus the
two fixtures.
## Not in this PR
- Other proof escape hatches (Isabelle `oops`, Coq `Admitted`, Agda
`postulate`, Idris `believe_me`, and so on) are still per-file and
unanchored. The same `occurrence_lines` pattern applies, but each needs
its own position check, so they are left to a follow-up rather than
widening this PR.
- A deed-format successor to the A2ML classification registry.

…e policy (#277)
I re-checked panic-attack's Idris2 proofs with Idris2 0.7.0, the version
`proven-tests.yml` pins. No CI job type-checks `src/abi/`, so the ✅
marks in `PROOF-NEEDS.adoc` had no receipt behind them.
## What the check found on `main`
| Module | Result on `main` | Design |
|---|---|---|
| `ClassificationSoundness.idr` (PA2) | passes | Sound and non-trivial
for its model |
| `AttestationUnforgeability.idr` | passes | Sound relative to its
hypotheses. Two of them are symbolic-model idealisations, and the header
overstated them as EUF-CMA and collision resistance. |
| `PatternCompleteness.idr` (PA1) | passes | **Vacuous**:
`GenericAnalyzer : HasAnalyzer lang` inhabits every language. The model
is also stale (see below). |
| `Stripping.idr` | **does not compile** | The theorem is true, but the
proof had two type errors, hidden behind a parse error. |
| `Types.idr` | **does not compile** | No theorems, despite a header
claiming three |
PA1's staleness: its `Lang` has 50 languages against 52 in Rust, missing
`C` and `Php`. `crossLangAlwaysApplied` also says cross-language checks
run on every file, but the Rust code now skips them for configuration
files.
## Commits
1. **`3dc4728` fix(abi): make the Stripping and Types Idris2 modules
type-check**
- **`Stripping.idr`:** matching on a `Char` literal only reduces when
the character is a literal, so the proof stuck on a variable head. The
model now classifies each character once (`Slash`, `Newline`, `Other`)
and steps on the class, and each proof carries `cls c = k`.
- The theorem statements are unchanged.
- All seven sanity checks are unchanged and pass.
- The new model equals the old one on all 349,525 strings of length ≤ 9
over `/`, newline, `x` and space.
- **`Types.idr`:** syntax-only fixes. Its header now says it declares
types only, and notes its drift from `src/types.rs`.
2. **`b1b1419` docs(proofs): record proof status against the estate
proof policy**
- `PROOF-NEEDS.adoc` now uses the proof policy's §5 tokens and §1.2
verifier mapping, pinned to `metadatastician/standards` `9bdf864`.
- It records a receipt for the Idris2 check and an honest status per
obligation.
- The implementation obligations are listed as `OPEN` for
Creusot/Pearlite and Verus: stripping, Patch Bridge reachability and
taint analysis.
## Verification
- All five `src/abi` modules type-check. The pass criterion is exit 0
and no `Error:` line; `idris2 --check` can exit 0 while printing an
error.
- **Negative controls:** a planted false lemma and a planted
non-terminating definition are both rejected.
- **No escape hatches:** every module sets `%default total` and uses
none of `believe_me`, `assert_total`, `postulate` or holes. The one
`believe_me` match is in a doc comment that bans it.
- **Kani note:** `cargo clippy --lib --bins --tests --benches
--all-features -- -F unsafe_code` compiles. The only `unsafe` is in
`examples/vulnerable_program.rs`, a deliberately buggy scan target.
- `PROOF-NEEDS.adoc` renders with Asciidoctor at `--failure-level WARN`.
## Not in this PR
- **CI gate for `src/abi`:** the modules are named `PanicAttack.ABI.*`
but live in `src/abi/`, so a plain `idris2 --check src/abi/X.idr` fails
on the module name. The status file records the gate as `OPEN`, with the
invocation to use.
- **PA1's redesign or retirement:** recorded as `OPEN`.

The merge placed '||| Equality on severity' between 'public export' and
'Eq Severity where'. Idris2 then rejects 'public export' as a declaration
start (idris-abi on b332b5f). Doc comment first, as on main.

Rebuild #282 on the flat src/abi/ layout that main keeps after #281.
Move the ABI modules back to src/abi/, drop the ipkg, and retire
PatternCompleteness.idr at its flat path. Point PROOF-PROGRAMME,
PROOF-NEEDS and EXPLAINME at src/assail/routing.rs for PA1.

Claude-Session: https://claude.ai/code/session_0136P7ZnmBahbhfkFEP6ark4
The base needs a manual change. This PR still targets claude/abi-idris2-gate, the branch of the closed #279. The API refuses a base change ("the pull request is part of a stack"). Please change the base to main in the web UI.
The Idris2 gate will stay red on main until #285 lands, because #277 merged without its last fix.
#277 merged at b332b5f. The fix for its one failing check (7070cb8) was
pushed to the branch but did not land.
## Problem
On main, `src/abi/Types.idr` has the `|||` doc comment between `public
export` and `Eq Severity where`. Idris2 0.7.0 rejects it:
```
Error: Keyword 'public' is not a valid start to a declaration.
PanicAttack.ABI.Types:23:1--23:7
```
So the required job "Idris2 ABI proofs type-check" fails on main and on
every PR based on it ([failing
run](https://github.com/hyperpolymath/panic-attack/actions/runs/42856302372/job/129970151246)).
## Change
Move the doc line above `public export`. One line, no change to any
declaration.
## Verification
The same commit is on #277's branch. The other 4 modules passed in the
failing run; this is the only error.

Review comments at @CHANGELOG.adoc:
- Around line 7-9: Update the CHANGELOG.adoc entry to match the four modules
currently in src/abi/: say “four” or that idris-abi checks all modules there. If
“five” describes the earlier state, make that historical context explicit and
note that PA1 was retired.
Review comments at @docs/design/GENERATION-PUBLISH.adoc:
- Line 73: Update the P3 row in the table to qualify the claim that a manifest
reader never fails: state that it holds only while CURRENT moves fewer times

reader failure. Keep the qualification consistent with the model’s bounds and
the implementation’s retry behaviour.
Review comments at @PROOF-NEEDS.adoc:
- Around line 68-70: Update the result statement in PROOF-NEEDS.adoc to match

`PatternCompleteness.idr`.
Review comments at @PROOF-PROGRAMME.adoc:
- Around line 17-21: Update the PA1 references in the document introduction, the
passage about dispatch completeness, and the analyzer-dispatch passage to
describe PA1 as a Rust test rather than a completed Idris2 proof. Replace the
stale language count of 49 with 51, while preserving the existing technical
scope of each passage.
Review comments at @src/abi/Stripping.idr:
- Around line 11-13: Update the header and the description near the model’s
reference to strip_proof_comments to state that the model is an abstraction, not
a mirror: it blanks comment text with spaces rather than truncating at the first
`//`, does not handle block comments, and proves idempotence only for the model.
Explicitly state that the Rust function is not proved, and distinguish these
existing differences from the future slices already listed.
Review comments at @src/assail/analyzer.rs:
- Around line 5884-5888: Update occurrence_lines to count newline characters
incrementally between successive match positions instead of rescanning each
prefix from the start of code. Preserve the returned line number for every match
while making the pass linear in the input size.
Review comments at @src/assail/routing.rs:
- Around line 120-160: Link each route to the analyzer actually called by adding
a source-scan test for the dispatch arms in `analyze_inner`; for every
`Route::X` arm, verify its body calls the analyzer identified by
`Route::analyzer()`. Reuse the approach in `analyzer_methods_in_source` so a
swapped dispatch call fails the test.
Review comments at @src/comment_marker.rs:
- Around line 165-167: Update the `trimmed_start.strip_prefix("(*")` branch to
distinguish an ML comment leader from a pointer-dereference expression before
returning. For code such as `(*fp)(arg); // ...`, continue scanning so the
trailing `//` marker is preserved; do not treat identifier prefixes such as
`panic_fp` as a sufficient distinction or misread `//` inside an ML block
comment.
Review comments at @src/main.rs:
- Around line 1451-1470: Update the probe logic in the outputs loop to
distinguish file-creation failures from cleanup failures. Preserve the “nothing
was written” message when opening the probe fails; if removing a newly created
probe fails, report the removal error separately and indicate that an empty file
may remain.
Review comments at @src/publish.rs:
- Around line 194-199: Update the publish flow to retain the previous manifest
while checking whether this generation is superseded, then, when mirroring,
remove previous manifest file names absent from self.files after mirroring
current files. Treat a missing stale mirror as success and keep the directory
sync after cleanup.
- Around line 161-164: Update mode_of_current to prefer the mode of
base_dir/name and fall back to the current generation’s file when unavailable.
Add a test that starts with a pre-existing 0600 report and verifies its mode
remains private after publishing.
- Around line 274-283: Update mirror so the copy fallback removes tmp and
returns the original error if copying, opening, or syncing the temporary file
fails. Preserve the existing cleanup when fs::rename fails.
Review comments at @tests/coverage_php_tests.rs:
- Around line 557-559: In the test around assail_kyaml_attested, add a small
drop guard for the reports directory before setting its permissions to 0o555, so
the guard restores mode 0o755 on normal return or panic. Remove the reliance on

State the bound on P3 in the table.
The row says a manifest reader "never fails". This holds only inside the model bounds. The models allow at most 3 writers, so CURRENT moves at most 3 times. The retry bound MaxRetries = 3 can therefore never be reached.
The code differs. read_consistent in src/publish.rs makes at most 16 attempts. It then returns generation kept moving. A reader that races more than 16 publishes can fail. The stress harness counts such failures as missing.
Add the bound to the row. For example: holds while CURRENT moves fewer times than the reader's retry limit. Alternatively, state that the reader can fail under sustained publishing.

Other passages still describe PA1 as an Idris2 dispatch proof.
The table row now says that PA1 is a tested Rust table and that the Idris2 model is retired. Line 52 still says "PA1 proves dispatch completeness (every category has a detector)". Line 247 still says "49-language analyzer dispatch (PA1 already covers this)". Both lines are stale: the language count is 51, and PA1 is a test, not a proof.

Inherit the mode from the top-level report when no current generation holds the file.
mode_of_current reads the mode only from the current generation. Take a user who has a private S.json (0600) from the old fs::write path. The first publish finds no CURRENT, so the new file gets 0o666 filtered by the umask. The mirror rename then replaces the private report with a more permissive one.
The same applies when a mirror is a copy because the hard link failed. A chmod on that copy does not change the generation file.
a_private_report_stays_private covers only the second publish, with hard-link mirrors. Prefer the mode of base_dir/name. Fall back to the current generation. Add a test that starts with a pre-existing 0600 report.

Remove stale mirrors of files that the new generation does not contain.
publish() refreshes a mirror only for names in self.files. A later run can write fewer files than an earlier run, for example without the --attest sidecar. The earlier run's top-level mirror, such as S.attestation.json, then stays beside the new S.json. A reader of the plain paths sees a mixed set. Normal operation can cause this, with no crash.
The models do not catch this. They fix NFiles for every generation, so P4 cannot fail this way.
Read the previous manifest in the same closure. After the mirror loop, remove each previous file name that is not in self.files. Treat NotFound as success.

)
Refs #276 and #212. This pull request does not close#276 by itself: the
first acceptance criterion needs a hosted run from an external caller
(see "Not shown yet").
## Symptom
Every repository that calls `scan-and-report.yml` as a reusable workflow
fails at **Run scan** with exit 127: `./target/release/panic-attack`
does not exist. Observed on hyperpolymath/echidna `main`, Security Scan
run 42351376316.
## Cause
In a reusable workflow, `actions/checkout` with no `repository:` checks
out the **caller**. The step `cargo build --locked --release` therefore
built the caller's crate. It worked only when this repository ran the
workflow on itself.
## Change
The workflow now fetches the scanner source at the commit of this
workflow file and builds that.
- **Source:** `job.workflow_repository` at `job.workflow_sha`. GitHub
documents both as the repository and commit of the workflow file that
defines the job.
- A caller that pins `scan-and-report.yml@<sha>` gets the scanner at
that SHA. It is never `main` by name, which keeps the #212 property.
- A run of this workflow in its own repository still builds the commit
under test.
- **Location:** the runner's temp directory, outside the workspace. The
scan cannot report on the scanner's own files.
- **Refusals:** the fetch step exits 2 for a repository that is not
`owner/name` and for a commit that is not a full SHA. It also checks
that the fetched `HEAD` is that SHA.
- **Cache:** the cache step keys on the scanner's workspace, not the
caller's.
- **Scan step:** it takes the target path from the environment and
quotes it.
No `uses:` reference changes, so `actions.lock` is unchanged.
One difference from the proposal in #276: the proposal names
`hyperpolymath/panic-attack` as a literal. This change takes the
repository from `job.workflow_repository`, so a rename of this
repository cannot break the fetch.
## Acceptance criteria
| Criterion | State |
|---|---|
| An external caller reaches `Run scan`, and the binary exists | Local
run only. Needs a hosted run from an external caller. |
| This repository's own run still builds the commit under test | Hosted
`workflow_dispatch` run on this branch: see the comment below when it
completes. |
| The report contains no findings from the scanner source | Holds by
construction: the source is outside the workspace. The local report
names no scanner path. |
## Evidence (local)
I extracted the changed steps from the workflow file and ran them on
x86_64 Linux with cargo 1.97.0.
- **Fetch:** succeeds at `c7b1c44` (`main` at that time). It is refused
with exit 2 for `main`, a short SHA, a malformed repository and an empty
repository.
- **Build:** 3 min 14 s. The binary exists at the path that the scan
step uses.
- **Scan:** a checkout of hyperpolymath/echidna as the caller. Exit 0,
schema 2.6 report, 951 of 951 files analysed, 130 weak points. The
report names no scanner source path, and no scanner source is inside the
workspace.
## Not shown yet
That `job.workflow_sha` names this repository's commit inside a call
from another repository. The local run cannot show it. A caller must pin
a commit that contains this change; echidna's `security-scan.yml` still
pins `be6ac46`.

Follow-up to #286. Refs #276.
## What failed
Run 42862049822 was the first run of `scan-and-report.yml` by
`workflow_dispatch`. It ran on the #286 branch before the merge.
- The new steps of #286 passed: the fetch of the scanner source and the
build (2 min 33 s).
- **Run scan** failed with exit 2: `a value is required for '<TARGET>'
but none was supplied`.
## Cause
`repo_path` and `fail_on_severity` are declared under `workflow_call`
only. A `workflow_dispatch` run has its own `inputs` context, so both
values were empty strings.
- The scan had no target.
- The severity gate would then reject the empty threshold
(`fail_on_severity must be one of ...`).
The step before #286 expanded the same empty input, so this path did not
work before #286 either. #286 did not cause it. The first manual run
showed it.
## Change
Declare both inputs under `workflow_dispatch`, with the same names and
the same defaults (`.` and `none`).
The expressions in the steps do not change. An explicit bad value from a
caller is still refused.
## Evidence
A hosted `workflow_dispatch` run on this branch is the proof. I add its
result in a comment when it completes.
This pull request does not show the external caller case of #276. That
still needs a caller that pins a commit with #286, for example echidna's
`security-scan.yml`.

Resolve PROOF-NEEDS.adoc in favour of this branch: main still carries
the PA1 rows from #277 (the vacuous PatternCompleteness model and the
"replace or retire PA1" open row), which this branch replaces with the
tested routing-table rows. cargo test --lib: 482 passed.

#288 replaces this PR. It uses the same branch, now merged with current main, and targets main. This PR stays on the closed #279's branch, because GitHub would not change its base ("part of a stack"). I am closing this one in favour of #288.
…ous PA1 (#288)
This replaces #282, which GitHub would not retarget from the closed#279's branch ("part of a stack"). The branch and its changes are the
same, now merged with current main.
## What
The Idris2 `PatternCompleteness.idr` (PA1) is replaced by the code that
actually does the routing, plus exhaustive tests.
- **New `src/assail/routing.rs`:**
- `route(Language) -> Route` is an exhaustive match with no wildcard.
- `Route::analyzer()` names the analyzer each route reaches.
- `runs_cross_language(is_configuration)` returns `!is_configuration`.
- **`analyzer.rs`:** the dispatch in `analyze_inner` now matches on
`route(file_lang)`. So the table is the code that runs, not a model of
it. Only the match arm heads changed, plus the cross-language guard.
- **`src/types.rs`:** adds `Language::ALL` (52 variants). An exhaustive
`ordinal` test keeps it complete.
## Claims and how they are tested (status `TESTED`)
Each test was seen to fail on a planted fault.
| Claim | Test | Planted fault it caught |
|---|---|---|
| (a) Every language analyzer is reached |
`every_language_analyzer_is_reached` | an unrouted `analyze_chapel` |
| (b) No language falls back to the generic analyzer while a dedicated
one exists | `no_language_falls_back_while_a_dedicated_analyzer_exists`
| Java sent to `Generic` |
| (c) Cross-language checks run exactly on non-configuration content |
`cross_language_checks_run_exactly_off_configuration` (a Justfile plus
`main.lua`, end to end) | `runs_cross_language` forced to `true` |
| (d) The README's language counts match the table |
`readme_language_counts_match_the_table` | the README's stale 49 |
Routing is not coverage. `Language::Unknown` goes to `InputAdapter`, and
a file there with no adapter is marked unsupported and skipped.
`PROOF-NEEDS.adoc` says so.
## Retired
- **`src/abi/PatternCompleteness.idr`**, for three reasons:
- It was vacuous: `GenericAnalyzer` inhabited its witness for every
language.
- It was stale: it covered 50 of 52 languages.
- It was partly false: it said cross-language checks always run.
- `PROOF-PROGRAMME`, `PROOF-NEEDS` and `EXPLAINME` now point PA1 at
`src/assail/routing.rs`.
- The pa1 entry in `0-AI-MANIFEST.a2ml` is deleted (a deletion only).
- The README now says 51 supported languages instead of 49, in the
badge, the capabilities list and the summary.
## Found, not fixed here (recorded as open obligations in PROOF-NEEDS)
- Unquoted `http://` URLs are missed by the cross-language check.
`analyze_cross_language` strips `//` comments from every file, which
also cuts `curl http://host` in shell and Justfile recipes.
- PA1 (a) to (c) still need a proof with Creusot/Pearlite and Verus.
## Not changed
`.machine_readable/6a2/{META,NEUROSYM,STATE}.a2ml` still name
`PatternCompleteness.idr`. They are legacy A2ML files, so they are left
for the owner or the deed conversion.
## Verification
- `cargo test --lib`: 482 passed, 0 failed, after merging current main.
- `cargo fmt --check` passes.
- Against main, the diff is only this PR's 10 files.
