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 weekly or on demand in read-only mode.
    • Reports identify potential file changes, missing or duplicate files, and selected licence-header issues without modifying files or creating pull requests.
    • Runs fail when actionable drift or mutation findings are detected.
    • Potential verification-bypass patterns are reported as advisory warnings without failing the run.
    • Clean runs confirm that no drift or proposed changes were detected.

Walkthrough

The Rhodibot workflow is now a read-only compliance canary. It detects drift and would-mutate conditions, reports findings, treats dangerous patterns as advisory, and fails only when DRIFT is positive.

Changes

Rhodibot compliance canary

Layer / File(s) Summary
Canary declaration and execution controls
.github/workflows/rhodibot.yml
The workflow now runs on a schedule or manual dispatch, uses read-only contents access, cancels obsolete runs, and does not respond to Hypatia runs or create pull requests.
Drift detection and result reporting
.github/workflows/rhodibot.yml
Checks report would-delete, would-rename, would-create, missing-file, duplicate-file, misnamed-file, and selected SPDX drift conditions. These findings increment DRIFT. Dangerous-pattern findings warn without incrementing DRIFT. The workflow writes a summary and exits with status 1 when DRIFT is positive.

Merge Risk: 🔵 Low · up to 803a1

This change safely converts an auto-fixing bot into a read-only compliance check that only reports and fails on detected drift; the one identified gap is that an unrelated line containing "AGPL-3.0" text in a scanned dotfile could trigger a false licence-drift failure, which is a minor, low-cost fix recommended before merge but does not block safe operation.

Explanation

The description explains the purpose and main workflow changes, but it does not follow the repository template. It omits the required Changes section, RSR Quality Checklist, Testing section, and Screenshots section.

Resolution

Update the description to use the required template. Add a Changes list, complete the RSR Quality Checklist, describe the tests that were run and their results, and add screenshots or terminal output if applicable. Retain the existing rationale and link to standards#759 as appropriate.

Match the SPDX header instead of all AGPL-3.0 text.

An unrelated line containing AGPL-3.0 would increment DRIFT and fail the canary. Match the complete SPDX header to prevent false licence-drift reports.

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 "$dotfile" ] && grep -Eq '^[[:space:]]*(#|;)[[:space:]]*SPDX-License-Identifier:[[:space:]]*AGPL-3\.0[[:space:]]*$' "$dotfile"; then
