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

  • Chores
    • Compliance checks now run in report-only mode and no longer modify repository files or create pull requests.
    • Missing required documentation, manifests, licences, or SPDX headers now fail the check and are reported in the workflow summary.
    • Verification-bypass findings are reported as warnings.
    • Scheduled and manually triggered checks now cancel superseded runs and have a 15-minute timeout.

Walkthrough

The Rhodibot workflow is now report-only. It detects compliance drift, records findings in GITHUB_STEP_SUMMARY, treats dangerous patterns as advisory warnings, and fails when drift is present. It no longer changes files or creates pull requests.

Changes

Rhodibot compliance canary

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow keeps scheduled and manual triggers. It adds concurrency cancellation, a 15-minute timeout, read-only contents permission, and actions/checkout@v7.0.1.
Drift detection and reporting
.github/workflows/rhodibot.yml
The workflow detects forbidden files, stale snapshots, manifest and documentation drift, and SPDX header drift. It records findings in GITHUB_STEP_SUMMARY.
Advisories and canary outcome
.github/workflows/rhodibot.yml
Dangerous-pattern matches produce warnings only. Detected drift fails the run. The workflow no longer mutates files or creates pull requests.

Merge Risk: 🟡 Moderate · up to 4028f

The new compliance canary will be rejected before it can scan for drift. Add the required action lock and immutable checkout SHA before merging.

Explanation

The description explains the purpose, scope, security rationale, and related migration. However, it does not follow the repository template because it omits the Changes section, the RSR Quality Checklist, and the Testing section. It also does not state whether screenshots are not applicable.

Resolution

Add the required template sections. List the key changes under Changes, complete the RSR Quality Checklist, describe the tests or validation performed under Testing, and state that Screenshots are not applicable if no screenshots or terminal output are available.

Add the action lock and pin actions/checkout to an immutable commit SHA.

actions/checkout@v7.0.1 violates the repository action-lock policy. The lock file is absent, so the scheduled and manual canary is rejected before checkout runs. Regenerate .github/workflows/actions.lock with the full SHA. contents: read does not replace action pinning.
