The RSR workflow in this repository is the mutating variant of rhodibot: it runs on a
weekly cron with contents: write + pull-requests: write, deletes files by glob, and
bulk-rewrites SPDX headers — which the standing licence policy forbids. It also interpolates
${{ steps.fix.outputs.FIXES }} into a run: block (repo-derived filenames, so
attacker-influenceable) and hardcodes a personal e-mail address.

This replaces it with the report-only canary that the estate template already ships — the
already-approved design, not a new one. Same weekly schedule, same drift signal, no mutation:
it reports what an auto-fixer would have changed and fails the run when it finds drift,
rather than editing anything. Licence/SPDX drift is reported for manual, owner-only
correction; rhodibot must never edit a licence header.

Part of the standards#759 migration (canary propagation, option (a)). The workflow's uses:
pins are unchanged, so actions.lock is unaffected.

The RSR workflow here is the mutating variant: weekly cron, write permissions,
glob deletes, a bulk SPDX `sed` sweep the licence policy forbids, a
`${{ steps.fix.outputs.FIXES }}` injection sink, and a hardcoded personal
e-mail. Replaced with the canary the template ships: same schedule, same drift
signal, reports instead of mutating.

Refs hyperpolymath/standards#759 (option (a), canary propagation).

📝 Summary

Summary by CodeRabbit

  • Changes
    • RSR compliance checks now operate in report-only mode and no longer modify repository files or open pull requests automatically.
    • Compliance drift is recorded in the workflow summary and causes the check to fail with a clear error notification.
    • Potentially unsafe verification-bypass patterns are reported as warnings without blocking the check.
    • The workflow now has a shorter execution limit and prevents overlapping runs from continuing unnecessarily.

Walkthrough

The RSR workflow is now a read-only compliance canary. It detects potential repository drift, reports warnings and summaries, and fails when drift exists. It no longer edits files or creates pull requests.

Changes

RSR compliance canary

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow uses read-only contents permission, a canary job name, concurrency cancellation, a 15-minute timeout, and no workflow_run trigger.
Drift detection and reporting
.github/workflows/rhodibot.yml
Mutation commands are replaced with read-only checks. Advisory warnings report unfixable gaps and dangerous patterns. The workflow writes a step summary and fails with an error annotation when DRIFT is greater than zero.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to b0bf7

The compliance canary can report a repository as clean when either required AI artifact is missing, undermining the workflow’s drift-detection purpose. Correct the checks before merging.

Explanation

The description clearly explains the purpose and key changes, but it does not follow the required template. It omits the RSR Quality Checklist, Testing, and Screenshots sections, and it does not record test or validation results.

Resolution

Restructure the description using the required Summary, Changes, RSR Quality Checklist, Testing, and Screenshots sections. Mark each applicable checklist item accurately and document the validation performed, including any tests that were not run and why.

Check the two A2ML artefacts independently.

docs/RSR_OUTLINE.adoc defines 0-AI-MANIFEST.a2ml and AI.a2ml as separate artefacts. The current OR check allows either file to be absent, and the rename warning treats AI.a2ml as an alias for the manifest.

Proposed correction
