Owner

The opt-in high/critical gate currently counts raw GitHub alert summaries as new findings. A PR that fixes an old alert can therefore be blocked by that alert until the PR reaches main. It also recounts findings already removed by the validated baseline.

Gate on Hypatia’s authoritative, baseline-filtered SARIF projection, matching the Security tab. Preserve raw findings for historical-debt review. Reject missing, malformed, truncated, or structurally incomplete SARIF; validate every present baseline with the existing validator even when the current scan is empty. Existing advisory callers retain their current behavior.

Validation: 23 actual-workflow success/failure controls pass, including planted high/critical findings, missing output, historical echoes and malformed baselines. The 9 SARIF baseline-filter tests and 8 apply-baseline tests also pass. This repairs the common blocker exposed by the language portfolio audit PRs.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Improved security scan blocking to evaluate findings after baseline filtering.
    • Blocking now validates committed baselines and filtered scan results, counting only error-level findings.
    • Reports now show current findings remaining after baseline filtering.
    • Added handling for incomplete, empty, or invalid scan result documents.
    • Improved baseline pattern matching and validation of invalid configuration.
  • Tests

    • Expanded coverage for baseline handling, severity mapping, missing results, unknown levels, multiple scan documents, and filtering outcomes.

Walkthrough

The workflow now validates baseline and SARIF inputs, filters historical findings, and counts only current SARIF error results. Baseline matching validates configuration and supports literal glob characters. Tests cover gate, filtering, and output contracts.

Changes

SARIF blocking gate

Layer / File(s) Summary
Baseline validation and matching
scripts/apply-baseline.sh, scripts/tests/apply-baseline-test.sh
The script validates mode and threshold values. It converts globs into anchored regular expressions. Tests cover literal glob characters, unrelated paths, malformed rules, and invalid configuration.
Blocking gate filtering and validation
.github/workflows/hypatia-scan-reusable.yml
The workflow pins the standards checkout, records baseline filtering, skips the separate baseline gate in blocking mode, and validates baseline and SARIF inputs before counting current errors.
SARIF projection and gate scenarios
scripts/tests/hypatia-blocking-gate-test.sh, scripts/tests/filter-sarif-by-baseline-test.sh
The tests generate SARIF severity mappings and check valid, malformed, incomplete, historical, unknown-level, baseline, and filtering-output scenarios.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 46960

The CI gate now evaluates validated, baseline-filtered SARIF errors rather than raw alert summaries, preventing approved historical findings from blocking pull requests while rejecting invalid filtering or SARIF inputs.

hyperpolymath dismissed coderabbitai[bot]’s stale review September 7, 2026 03:16

The change request targets 0a58b88. Commit 3bc7de6 implements the requested explicit filter-completion signal and refusal when filtering does not complete. The reviewer has resolved its only thread. All current checks pass, including 24 gate controls and 13 filter controls. Dismissing this obsolete automated review so the normal branch rules can evaluate the corrected revision.

…+ regen) (#947)

Fix-forward for the red `main` tip (`4f7f02ca`, #899's squash). Settles
every failing check by code repair where a repair exists, and by Hypatia
baseline triage where the failure is new-scanner-module findings or
accepted debt. Mirrors stay parked (unchanged by this PR).

**Attribution (verified per failure, not assumed):** #899's merge broke
the lock gate (stale deno orphan) and exposed the stale registry; the
reorg broke wave4/C7, three scorecard checks, the wave3 drift control
and `.gitleaksignore`; everything else (Hypatia baseline drift, shape
suite, debtfile contradiction, SonarCloud, the `$/` corruption) predates
#899 and is repaired here because red is red.

## Code repairs (`a5e5ea54`)

- **Lock:** drop two orphan entries — `denoland/setup-deno`
(Deno-retirement leftover; failed `gh` verification as `stale`) and
`asana/push-signed-commits` (leftover of the local signed-push
migration; failed Hypatia as `transitive_dependencies_missing`). `gh
actions-lock --verify-local` exits 0.
- **Governance shape suite (was 6/14, now 14/14):** restore the
`actions-lock-verify` job (2026-09-02 regularisation §6.2 step 2a) by
transplanting #899's lock gate + exemption ledger out of `workflow-lint`
into its own required context; fix two hardcoded `runs-on`.
- **Timeouts/permissions:** `timeout-minutes: 10` on 5 jobs;
workflow-level grants narrowed to job level in 5 workflows; 6
provably-dead grants removed (each verified by reading every step of the
affected jobs — see commit message).
- **Hypatia validator:** drop the incidental `length > 0` (#771 broke
the `empty findings are valid` control; #741/#742 treat empty as valid).
All 9 gate controls re-verified.
- **Debtfile:** #783 shipped two contradictory encodings; test +
spec-glossary now match the validator + MUST section (4-field), plus the
stable-id grammar check the spec requires. Suites 23/23 and 17/17.
- **Reorg fallout:** wave4 conformance path, 3 scorecard checks (agentic
`cd`, session-mgmt exclusion, gatekeeper M1 manifest count), wave3
drift-control dashboard path, `.gitleaksignore` historical paths
(verified: `gitleaks detect` → no leaks).
- **`signed-push-smoke`:** repair committed `$/` verifier-mutation
corruption → `./`.
- **SECURITY.md** added (scorecard SecurityPolicy +
`missing_requirement`).
- **SonarCloud:** S3923 collapse, curl `--proto '=https'`,
NOSONAR+justification on 5 operator-owned CLI paths and the
base-checkout fork gate.

## Baseline triage (`b0f1e95b`, 129 → 210 entries)

The floating scanner grew `content_patterns` (69) and
`research_extensions` (43) since the baseline was written; at
`BLOCKING_THRESHOLD: info` the job cannot pass without acknowledging
them. 81 file-level entries, each with note + `expires_at: 2026-12-22` +
tracking issue #936–#945 (filed by this change). Verified:
`apply-baseline.sh blocking` at threshold `info` over the 133 observed
findings keeps 0. Also: the baseline schema now accepts the scanner's
full severity vocabulary (`warn`, `informational` — `rank()` already
handled `warn`; without this, research findings could never be
acknowledged).

## Regen (`c7cd8c90`)

Registry + topology regenerated over the repaired tree; `--check` green.

## Owner actions (cannot be fixed in code)

1. **`HYPATIA_SCAN_PAT` expired** — Identify Repositories 401s on every
run. Refresh the secret.
2. **Watch for the phantom `security-gate-pr-target` push-run** — a
0-job instant-failure run exists on `4f7f02ca`; no caller, valid YAML,
PR-only triggers. If it recurs on the post-merge main, it needs
console-side diagnosis.
3. **Review the dropped permissions + NOSONARs** — each is documented
in-code; revert any single hunk if a runtime surprise appears.
4. **#936–#945** — the ten triage buckets (debt paydown vs
re-acknowledgement by 2026-12-22).

## Verification

Local: lock verify 0, gitleaks clean, deed self-test + fixtures OK,
debtfile 23/23 + 17/17, wave4 15/15, shape 14/14, registry/scorecard
`--check` OK, scorecard `--verify` clean except k9/M4 (needs cargo —
present in CI, which passed it on main; untouched by this PR).
Ruby-dependent suites can't run in this environment; the Hypatia gate
controls were re-verified by extracting the workflow steps and running
all 9 controls (9/9).
