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, detecting repository drift without automatically modifying files or opening pull requests.
    • Workflow failures now clearly identify compliance issues through warnings and run summaries.
    • Checks cover file naming, required compliance files, licensing headers, stale snapshots, duplicate files, and verification-bypass patterns.
    • Workflow execution now uses read-only repository access, a 15-minute timeout, and concurrency controls.

Walkthrough

The workflow now runs as a read-only canary. It detects compliance drift, records warnings in the step summary, and fails when drift is found. It no longer changes files or creates pull requests.

Changes

Rhodibot canary workflow

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow adds concurrency control, uses read-only contents permission, upgrades checkout to v7.0.1, adds a 15-minute timeout, and renames the job to canary.
Drift detection
.github/workflows/rhodibot.yml
The workflow checks banned files, stale snapshots, legacy names, duplicate community files, SPDX headers, required files, compliance files, and dangerous verification-bypass patterns. The checks only report findings.
Finding reporting
.github/workflows/rhodibot.yml
The workflow writes an error and summary when drift exists, then exits with status 1. It removes mutation, pull-request, report, and related output steps.

Priority: ⬇️ Low

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

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 86ad3

The workflow can overlook licence drift and uses a mutable action reference. Fix these compliance and supply-chain issues before merging.

Detect non-MPL SPDX headers in the dotfiles.

The exclusion allows AGPL-3.0-or-later to pass without a warning. The dotfile policy rejects AGPL-3.0 references, including this variant. Read the SPDX header and warn when it is not exactly MPL-2.0.

Proposed fix
           for dotfile in .gitignore .gitattributes .editorconfig; do
-            if [ -f "$dotfile" ] && grep "AGPL-3.0" "$dotfile" 2>/dev/null | grep -v "AGPL-3.0-or-later" | grep -q .; then
-              warn "$dotfile carries an AGPL-3.0 SPDX header; estate policy is MPL-2.0 — fix MANUALLY (owner-only, never auto-edited)"
+            spdx=$(grep -m1 -E 'SPDX-License-Identifier:' "$dotfile" 2>/dev/null || true)
+            if [ -n "$spdx" ] && ! grep -Eq 'SPDX-License-Identifier:[[:space:]]*MPL-2\.0[[:space:]]*$' <<< "$spdx"; then
