fix(linguist-check): exclude test corpora from the Python ban - #31

Conversation
The gate asked "does this repo contain .py" when the doctrine it enforces means "is this repo written in Python". Those are different questions, and the difference fails exactly the repos that are doing their job properly: a static analyser, linter or parser needs Python source as test input, and that input is data, not implementation. pons-asinorum is the concrete case. Every one of its 18 .py files sits under fixtures/ as the positive/negative corpus for the Python analyser its own ADR-0002 mandates. The gate redded it for shipping the test data its design requires. Test-corpus directories are now excluded by name (fixtures, corpus, corpora, testdata, test-data, test-corpus, samples, vendor, node_modules). Anything outside them is still implementation and is still banned. The gate now also names the offending files instead of only asserting that some exist. Verified by mutant, not by inspection: - pons as-is -> rc=0, "18 Python file(s) ... allowed" - .py planted at repo root -> rc=1, names ./scratch_impl.py - .py planted in crates/ -> rc=1, names ./crates/.../helper.py Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WRvDivYwLSeVCJUrfjic3f

Do not prune hidden directories outside EXCLUDED_DIRS.
find prunes ./.github because it matches -path "*/.*". It therefore skips .github/tool.py, although .github is not an exempt directory. The detector can pass with a prohibited Python file.

…e, live CI (#25) ## What this is Phase 0 of the v0.1.0 gate. The premise "pons doesn't work" turned out to be false in an interesting way: on `main` the engine, the 8 T0 rules, the 5 tree-sitter grammars, the 86-file fixture corpus and the falsifier gate all genuinely work — a real scan of `google-flatbuffers-bounty` yields 35 findings across Python and TypeScript in 8.1s, spot-verified accurate. What did not work was everything *around* the engine. This PR fixes that layer. ## The CLI had no `--version` clap's `#[command(...)]` block omitted `version`, so `pons --version` was an *unexpected argument* and exited 2. It now prints `pons 0.1.0` and exits 0. ## Five rules printed their own id as the message `RawFinding::new`'s 4th positional argument is the human message, and five T0 rules passed their rule id into it. Output read: ``` [WARN] self-assignment: self-assignment ``` Fixed in `empty-effect-loop`, `self-assignment`, `string-concat-in-loop`, `unreachable-after-jump`, `while-true-no-break`. The other three already had prose. This is the kind of defect a test suite that never runs the binary cannot see — which brings us to the main item. ## `tests/e2e.sh` was a vacuous gate The old suite was 254 lines that **never once executed the binary**. It asserted that documents existed, announced a "planning phase" that ended when PR #19 merged, referenced `GOVERNANCE.md` / `CODE_OF_CONDUCT.md` (this repo ships `.adoc`), asserted a `0-AI-MANIFEST.a2ml`, and ran a template instantiation test. It scored 16 pass / 3 fail while the binary could not print its own version. Rewritten into two explicit halves — repository shape, and binary behaviour — now **35 pass / 0 fail / 0 skip, with 16 assertions that execute the binary**: - `--version` and `--help` exit 0 and say the right things - the known-answer positive corpus fires its rule, with a location and an evidence note - the message is asserted **not** to be a repeat of the rule id, so the defect above cannot come back silently - the falsification invariant across all 8 negative corpora. The predicate is *"the corpus does not fire its own rule id"*, not *"the scan is silent"* — `while-true-no-break/negative` legitimately fires `constant-condition`, and a silence-based assertion would have been wrong about that - the full ADR-0005 exit-code matrix: 0 with findings, 1 under `--fail-on warn`, 0 under `--fail-on error`, 2 for a nonexistent path Three deliberate properties: - **It fails rather than skips when no binary is found.** A skip is not a pass. - **Exit codes compare numerically** (`-eq`), because `grep -q "1"` also matches rc=12. - **Non-vacuity is itself gated.** `just e2e-mutant` runs the whole suite against `PONS_BIN=/bin/true` and fails if it passes. `rust-ci` runs the same check. Measured: the mutant dies with 7 failures, rc=7. The suite cannot quietly become vacuous again without a red square. `tests/e2e/template_instantiation_test.sh` is removed along with its caller. ## Both red workflows on `main` **CodeQL** was pinned to `29b1f65c`, which resolves to nothing at all — the commits API returns 422 — so every run died. Worse, the matrix listed `language: actions` only, meaning CodeQL **had never once opened `crates/`**. Repointed to `1c5b6756`, the commit that `v4.38.1` dereferences to (verified via the commits API before committing — a tag sha is not a commit sha, and pinning the former is how this broke), and `rust` added to the matrix. **`main-estate-audit`** called `hyperpolymath/cicd-suite/.github/workflows/main-estate-audit.yml@feat/cicd-workflow-call`, a branch that 404s. That is not a failing job — it is startup death with `jobs=0`, which is why it never showed as red in a useful way. Repointed at the pinned reusable `3b4afafa`. > **Flagged for your override.** The decision was "land the composites *and > wire them up*". Measurement then showed this repo's `main-estate-audit.yml` > already wires all 26 composites via cicd-suite's reusable — it was simply > calling a dead ref. Vendoring 26 local copies *and* wiring them would either > double-run every gate or need a duplicate invoking workflow, from an already > stale snapshot (cicd-suite has since replaced `zig-hexadeca-check` with > `zig-unified-api-adapter-check`). **Repointing is the elegant-and-correct > long-term arm** and is strictly no worse than the status quo, which is a dead > 404. It is also trivially reversible. Say the word and I will vendor instead. ## The docs were lying `README.adoc`, `ARCHITECTURE.adoc` and `EXPLAINME.adoc` all claimed planning was complete and implementation not started — months after M0–M2 merged in PR #19. `ARCHITECTURE.adoc` additionally listed 4 ADRs when 5 exist, and labelled `tests/` and `benches/` as "planning phase" when both are real and `tests/` runs in CI. `wiki/` is converted from AsciiDoc to **metadatastician/berrywiki** Markdown — nine pages carrying the berrywiki metadata comment block (`id` / `parent` / `position` / `kind` / `tags` / `archived`), with `_Sidebar` and `_Footer` deliberately carrying none, per the live berrywiki course template rather than per the ADR. Stale status claims in `Home` and `Roadmap` corrected, and `hyperpolymath/pons` → `hyperpolymath/pons-asinorum` fixed in the sidebar. `docs/wiki.adoc` documents the format, why the metadata is an HTML comment rather than YAML frontmatter (GitHub Wiki renders frontmatter visibly), and why wiki content is the estate's documented `.md` exception to the AsciiDoc default. ## Governance `dependabot.yml`'s `open-pull-requests-limit` and the two ruleset JSONs are taken from the `49774e8` spike **keeping every SHA pin**; that commit's `actions/checkout@v7 → @v5` de-pin, which would have undone merged PR #24, is discarded rather than merged. Verified the dependabot change touches the github-actions ecosystem only, leaving cargo's `limit: 0` and its documented security-PR rationale intact. Both spikes are preserved on the remote as `spike/estate-governance-sync-2026-09-15` and `spike/rookie-scanner`. ## Dependency Needs hyperpolymath/cicd-suite#31, which excludes test corpora from `linguist-check` — pons ships 18 Python files as scanner fixtures and the gate banned Python by extension anywhere in the tree. **Merged as `6ff6057`**, so the estate-audit run on this PR should pick it up (the reusable references its composites at `@main`). ## Verification | Gate | Result | |---|---| | `cargo fmt --all --check` | clean | | `cargo clippy --workspace --all-targets -D warnings` | clean | | `cargo test --workspace` | 75 passed, 0 failed | | `just falsify` | green | | `just e2e` | **35 pass / 0 fail / 0 skip** | | `just e2e-mutant` | mutant dies (rc=7) | | 26 estate gates, locally | all pass | ## Note for M8 `Immutable-Tags` (22960816) is `active` with **zero bypass actors** and rule types `creation`, `deletion`, `non_fast_forward`, `update`, `required_signatures` over `~ALL`. Signing is configured, so the signature requirement is satisfied — but `creation` with no bypass actor means **nobody can create the `v0.1.0` tag**, including you. Rulesets have no implicit admin bypass. That needs settling before M8, not at M8. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01WRvDivYwLSeVCJUrfjic3f --------- Signed-off-by: Jonathan D.A.

…nsumer (#35) ## The cure was green here and inert everywhere else `fa71ac2` (#32) cured the composite `-e` kill. `0c1bc9f` (#34) restored the lockfile pins #28 dropped. Both merged green. **Neither reached a single consumer**, and nothing was red to say so. pons-asinorum was repointed at `0c1bc9f` (pons#26) and its estate audit *still* died at `Required Files Gate` — 82 ms, silent, exit 1, 25 downstream gates skipped. Identical to before the cure. ### Why The reusable invokes its gates by **branch** ref: ```yaml uses: hyperpolymath/cicd-suite/actions/required-files-check@main ``` A branch ref is *trusted from the lockfile*, and the runner executes **the commit the lockfile names** — not the branch tip. This lock pinned `cicd-suite@main` at `9adb3908`, four commits back: | commit | PR | carried | |---|---|---| | `0c1bc9f` | #34 | lock pins restored | | `fa71ac2` | #32 | the `-e` cure (3 + 1 guards) | | `6ff6057` | #31 | linguist-check | | `3b4afaf` | #28 | (the regression) | `9adb3908` has **0** of those guards. So no SHA a consumer picks for the *reusable* can reach a cured *composite*. The lock's `@main` entry is the real gate, and re-pinning it is the actual delivery step — the one #31, #32 and #34 all skipped. ## What this does 1. Bumps `dependencies['hyperpolymath/cicd-suite@main'].commit` to `0c1bc9f`. Ancestor-clean fast-forward (`9adb3908` is an ancestor of `0c1bc9f`); the transitive `uses:` list is unchanged, so `dependencies:` needs no other churn. 2. **Makes it impossible to forget again.** `tests/lock-transitive-closure.sh` gains a third assertion: for any self-referencing branch pin, the `actions/` tree at the locked commit must equal `HEAD`'s. On drift it names the files. 3. `shell-contract` gains `fetch-depth: 0` so the locked commit is present to compare against. The house pattern for this is a follow-up *"pin cicd-suite lock at `<sha>`"* commit — `f8c8f4a`, `4f9a7a4`, `373714a` all do exactly this. It has been carried by memory, and memory dropped it three times running. Now it is a test. ## Non-vacuity — twice **The assertion was written before the bump and caught the live defect**, naming all three drifted composites: ``` FAIL hyperpolymath/cicd-suite@main pins 9adb390..., whose actions/ tree differs from HEAD actions/linguist-check/action.yml actions/required-files-check/action.yml actions/spdx-license-check/action.yml ``` And its first draft printed its header while checking *nothing* — an ERE `sed` has no lazy quantifiers, so `.git` stayed on the repo name and no dependency key ever matched. A header is not a check, so the block now carries its own non-vacuity counter, separate from block 1's. ## Local ``` tests/lock-transitive-closure.sh PASS=9 FAIL=0 tests/composite-shell-contract.sh PASS=7 FAIL=0 (mutant dies silently) ``` ## Acceptance `Composite shell contract` green with the new assertion passing — and then pons#26's audit re-measured. Per the standing owner ruling, the gates that have been *skipped rather than passing* may now surface new findings; those become issues with acceptance criteria, not blockers on this PR. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01WRvDivYwLSeVCJUrfjic3f Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
