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
    • Updated repository checks to report detected compliance and file drift without automatically modifying or committing changes.
    • Reduced automation permissions to read-only for improved safety.
    • Added concurrency controls to prevent overlapping checks.
    • Checks now clearly flag issues for manual correction and fail when drift is detected.

Walkthrough

The Rhodibot workflow now runs as a read-only compliance canary. It detects file, licence, manifest, and documentation drift, reports findings in workflow output, and fails when drift exists. It no longer edits files, commits changes, or creates pull requests.

Changes

Rhodibot compliance canary

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow uses the canary job, read-only contents permission, concurrency cancellation, and no workflow_run trigger.
Drift detection and reporting
.github/workflows/rhodibot.yml
The script reports would-mutate conditions and licence drift without changing files. Verification-bypass matches are advisory. The workflow writes a summary and exits with status 1 when drift exists. It no longer creates branches or pull requests.

Priority: ⬇️ Low

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

Change: Bug fix

Merge Risk: 🟡 Moderate · up to ab527

The compliance canary can report a clean result while dotfiles retain a non-compliant AGPL-3.0-or-later header. Correct the detection before merging so required licence drift remains visible.

Detect AGPL-3.0-or-later as licence drift.

The second grep removes AGPL-3.0-or-later matches. The dotfile policy requires MPL-2.0, so this variant must also trip the canary.

Proposed fix
-            if [ -f "$dotfile" ] && grep "AGPL-3.0" "$dotfile" 2>/dev/null | grep -v "AGPL-3.0-or-later" | grep -q .; then
+            if [ -f "$dotfile" ] && grep -Eq 'SPDX-License-Identifier:.*AGPL-3\.0' "$dotfile" 2>/dev/null; then
