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
    • Automated checks now report detected repository drift instead of modifying files or opening pull requests.
    • Drift findings cause the workflow to fail with a clear error annotation and summary.
    • Verification-bypass patterns are reported as warnings without failing the workflow.
    • Workflow permissions have been reduced to read-only access.

Walkthrough

The workflow now acts as a report-only compliance canary. It detects drift, reports findings in the job summary, and fails when drift exists. It no longer modifies files or creates pull requests.

Changes

Rhodibot compliance canary

Layer / File(s) Summary
Workflow boundary and permissions
.github/workflows/rhodibot.yml
The workflow is renamed, adds concurrency control, narrows permissions to contents: read, and updates the checkout action.
Drift detection checks
.github/workflows/rhodibot.yml
The scan reports banned files, stale snapshots, naming conflicts, missing files, licence-header drift, and verification-bypass patterns without modifying files.
Drift result reporting
.github/workflows/rhodibot.yml
The workflow appends results to $GITHUB_STEP_SUMMARY, fails when drift is found, and removes fix outputs and pull-request creation.

A harmless mention of AGPL-3.0 in a checked dotfile can make the compliance canary fail. Restricting the check to the SPDX identifier avoids false compliance failures.

Match the SPDX identifier field.

The current grep matches any dotfile content that contains AGPL-3.0. A non-header mention can therefore increment DRIFT and fail the canary. Match SPDX-License-Identifier: with the exact legacy identifier instead.
