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.
    • Detected compliance drift is summarised in the workflow results and causes the check to fail for review.
    • Verification-bypass pattern matches are reported as advisory notes and do not independently fail the check.
    • Workflow runs now use concurrency controls to avoid overlapping checks.

Walkthrough

The Rhodibot workflow is now a report-only compliance canary. It detects drift without changing repository files, writes findings to the job summary, and fails when actionable drift exists. Advisory verification-bypass findings do not increment the drift counter.

Changes

Compliance Canary workflow

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow removes the completion trigger, adds concurrency control, narrows permissions, sets a timeout, and updates the checkout action.
Non-mutating drift detection
.github/workflows/rhodibot.yml
The checks now report would-mutate conditions instead of deleting, renaming, creating, or rewriting files. Licence drift is reported for manual correction. Verification-bypass patterns produce advisory notes.
Canary result reporting
.github/workflows/rhodibot.yml
The script writes a green or red result to $GITHUB_STEP_SUMMARY and exits with status 1 when DRIFT is greater than zero.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 10a64

The compliance canary can report success when a checked dotfile has an unapproved AGPL-3.0-or-later header. Correct the detection before merge so licence drift remains visible for owner review.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

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

The grep -v "AGPL-3.0-or-later" filter removes this non-MPL SPDX value from the result. A dotfile with SPDX-License-Identifier: AGPL-3.0-or-later therefore leaves DRIFT unchanged and can report a clean canary, although Line 69 requires MPL-2.0. Remove the exclusion so all AGPL-3.0 variants 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 "$dotfile" ] && grep -q "AGPL-3.0" "$dotfile" 2>/dev/null; then
