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

  • Bug Fixes

    • Compliance checks are now read-only and report detected drift without automatically changing files or opening pull requests.
    • Checks now fail when compliance drift is detected, with clearer warnings for missing, stale, misnamed, or mismatched repository files.
    • Verification-bypass patterns are reported as advisory notes.
  • Security

    • Workflow permissions have been restricted to read-only access.

Walkthrough

The Rhodibot workflow now runs as a read-only compliance canary. It reports would-mutate drift, limits permissions, prevents overlapping runs, and fails when drift exists. It no longer edits files or creates pull requests.

Changes

Rhodibot compliance canary

Layer / File(s) Summary
Workflow controls
.github/workflows/rhodibot.yml
The workflow keeps scheduled and manual triggers, adds concurrency cancellation, uses contents: read, renames the job to canary, and upgrades checkout.
Read-only drift detection
.github/workflows/rhodibot.yml
The checks report compliance drift and dangerous patterns. They no longer delete, rename, rewrite, or create files.
Canary result reporting
.github/workflows/rhodibot.yml
The workflow writes the drift count to the step summary and exits with status 1 when the count is greater than zero.

The compliance report can show a misleading verification-bypass advisory for unrelated source text. Use fixed-string matching to keep the canary output accurate.

Match verification-bypass tokens literally.

grep treats Obj.magic as a regular expression, so a file containing ObjXmagic can match. The loop then emits an advisory warning through note; it does not increment DRIFT or fail the canary.

Proposed fix
-            count=$(grep -rl "$pattern" --include='*.idr' --include='*.v' --include='*.lean' --include='*.hs' --include='*.ml' --include='*.res' . 2>/dev/null | grep -v node_modules | wc -l || true)
+            count=$(grep -rlF --include='*.idr' --include='*.v' --include='*.lean' --include='*.hs' --include='*.ml' --include='*.res' -- "$pattern" . 2>/dev/null | grep -v node_modules | wc -l || true)
