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
    • Compliance checks now run in report-only mode and no longer modify repository files or create pull requests automatically.
    • Runs provide warnings identifying detected compliance drift.
    • The workflow fails when drift is found and reports a clean result when no issues are detected.
    • Automatic checks triggered by related workflow runs and write access for pull requests have been removed.

Walkthrough

The workflow now operates as a report-only compliance canary. It detects conditions that previously triggered automatic fixes, reports warnings, and fails when drift exists. It no longer creates pull requests or modifies repository files.

Changes

Compliance Canary

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow uses scheduled and manual triggers, adds concurrency control, removes pull-request write permission, sets a timeout, and upgrades checkout to v7.0.1.
Report-only drift detection
.github/workflows/rhodibot.yml
The scan reports banned files, stale snapshots, naming issues, SPDX issues, missing files, and dangerous-pattern matches without changing repository contents.
Canary outcome
.github/workflows/rhodibot.yml
The workflow fails with an error annotation when drift exists. It reports a clean result when no drift exists. It no longer creates pull requests.

The canary can execute a changed upstream checkout action without a repository review. Pinning the known v7.0.1 commit removes this bounded supply-chain exposure.
