ci(rhodibot): switch to the report-only canary (standards#759) - #76
Conversation
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).

WalkthroughThe Rhodibot workflow now runs as a read-only compliance canary. It detects repository drift, reports findings in the workflow summary, treats bypass patterns as advisory, and fails when would-mutate drift is present. ChangesRhodibot compliance canary

Restore the immutable checkout reference.
This changes actions/checkout from a full SHA to the movable v7.0.1 tag. GitHub documents that only a full commit SHA is immutable and that tags can be moved. A retargeted tag executes before the detector and can alter the workspace or canary result. Restore the SHA already used for v7.0.1. (docs.github.com)

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Injection
Reachability: Internal

CWE: CWE-74 — Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
Sanitise messages before emitting workflow commands.
Line 55 passes a checked-out filename to warn. Double quotes prevent shell injection, but they do not remove CR or LF characters. A matching filename with a newline can add a ::stop-commands:: command to stdout and suppress subsequent canary annotations. GitHub processes :: commands from stdout. Remove CR and LF before emitting the warning. (docs.github.com)

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, andbulk-rewrites SPDX headers — which the standing licence policy forbids. It also interpolates
${{ steps.fix.outputs.FIXES }}into arun:block (repo-derived filenames, soattacker-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#759migration (canary propagation, option (a)). The workflow'suses:pins are unchanged, so
actions.lockis unaffected.
