Owner

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
    • RSR compliance checks now run in report-only mode and identify potential file changes without applying them or opening pull requests.
    • Checks now fail when compliance drift is detected, with clearer warnings for deletions, renames, creations, unfixable gaps and licence headers requiring manual attention.
    • Verification-bypass patterns are reported as advisory notes.
    • Workflow permissions are read-only, with improved concurrency protection and a 15-minute timeout.

Walkthrough

The workflow now runs as a read-only RSR compliance canary. It reports potential mutations, records findings in the job summary, and fails when drift is detected. It no longer edits files or opens pull requests.

Layer / File(s) Summary
Workflow execution controls
.github/workflows/rhodibot.yml
The workflow uses scheduled and manual triggers, read-only contents access, concurrency cancellation, and a 15-minute timeout.
Report-only drift detection
.github/workflows/rhodibot.yml
The scan reports potential deletions, renames, creations, SPDX corrections, missing files, and advisory verification-bypass patterns without modifying files.
Canary outcome reporting
.github/workflows/rhodibot.yml
The workflow writes clean or tripped summaries and exits with status 1 when drift exists.

Owners may need to search logs to determine required manual corrections, and harmless source text can produce an advisory warning. These are localized canary-reporting issues that should be corrected before relying on its results.

Write each would-mutate finding to the job summary.

warn() emits an annotation and increments DRIFT, but it does not write the finding to $GITHUB_STEP_SUMMARY. The summary contains only the heading and the final count, so owners cannot identify the required correction from the job summary.

Proposed fix
-          warn() { echo "::warning title=Rhodibot canary::$*"; DRIFT=$((DRIFT+1)); }
+          warn() {
+            echo "::warning title=Rhodibot canary::$*"
+            printf '%s\n' "- $*" >> "$GITHUB_STEP_SUMMARY"
+            DRIFT=$((DRIFT+1))
+          }

Match advisory patterns literally.

grep interprets Obj.magic as a regular expression. A file containing ObjXmagic can therefore produce an advisory finding even though it does not contain the Obj.magic construct. Use fixed-string matching for these listed patterns.
