Why

The checks that stop a risky change to the organisation's live GitHub settings (an unreleased change, or a deletion nobody acknowledged) run from each pull request's own copy of CI. A pull request can therefore edit those checks out of its own path and still merge with everything green.

What

An organisation rule now requires the same checks from this repository's reviewed main, which a pull request cannot change. They read the pull request only as data. This follows the pattern the monorepo's CI check already uses, with no bypass. A test pins the rule and makes sure the checks never run the pull request's own scripts.

Operational note: the rule reaches GitHub only with the next release of this repository. If main ever stops rendering, recovery needs an organisation owner for a short break-glass step, described in AGENTS.md.

Fixes #183

🤖 Generated with Claude Code

A pull request could edit or remove the release-contract and deletion
validators from its own ci.yaml and still pass CI - Required Checks. An
organization ruleset now requires .github/workflows/deploy-guards.yaml from
this repository's main; it checks the validators out at github.workflow_sha
and reads the candidate only as data. tests/deploy-guards-ruleset.sh pins
the ruleset and the trusted-checkout wiring.

Fixes #183

📝 Walkthrough

Walkthrough

The pull request adds a trusted deploy-guards.yaml workflow for pull requests and merge queues. It checks out validators at github.workflow_sha, validates release contracts and deploy deletions, and handles render failures as unknown results. A new organization ruleset requires this workflow from refs/heads/main. Tests validate the rendered ruleset and workflow structure. Documentation and ruleset inventory counts now include the fourth managed ruleset.

Priority: ⬆️ High

Severity of issue fixed: High

Merge Risk: 🟠 High · up to fc853

Merge-queue candidates can pass the required workflow without either deploy guard running, defeating the protection this PR introduces. Fix this before merge.

- Line 40: Update .github/workflows/deploy-guards.yaml at lines 40-40 so
release-contract validation runs for merge_group, or fails closed when
merge-group metadata cannot be resolved; update lines 52-52 so deploy-deletion
validation compares the merge-queue base and candidate; update
tests/deploy-guards-ruleset.sh lines 63-64 to assert both validator steps
execute for merge_group, not merely that the trigger is declared.

In `@tests/world-at-ruin-regression-ruleset.sh`:
- Around line 60-61: Update the ruleset inventory assertions in the test around
the existing README grep to validate the complete breakdown: 10 imported, 4
managed, and 10 UI-managed rulesets, not only the total of 24. Keep the existing
failure behavior and align each assertion with the inventory claim in the
failure message.

A merge-group event carries no pull-request title, commits or body, so a
merge_group run of deploy-guards.yaml skipped both validators and passed.
Drop the trigger so a merge queue waits on the required check instead, and
assert that. The ruleset inventory test now checks the imported and managed
counts its failure message claims, not only the total.

  • Programmatically tested. tests/deploy-guards-ruleset.sh failed before the change (no ruleset rendered) and passes after. Four ablations of the workflow each fail it for the named reason: a validator run from the candidate checkout, the trusted checkout at github.sha instead of github.workflow_sha, persisted checkout credentials, and a re-added merge_group trigger. The inventory test now checks each count its message names, and two ablations fail it (a missing README row, a missing rendered managed ruleset). All eleven existing suite commands, actionlint, zizmor, shellcheck and shfmt pass locally, and all CI checks pass at this head.
  • Reviewed. CodeRabbit's round-1 review at fc853d8e raised two valid findings, both fixed in this head with threads resolved. For this head, CodeRabbit was requested first and refused on its rate limit. Codex then reviewed this head (comment 5657025046, Reviewed commit: be9d6474b8) and found no issues, with no finding comments or inline threads.
  • Tried as a user. In real CI, 🛡️ Deploy guards / Enforce deploy/ guards from reviewed main ran and passed. That was the pull request's own copy, so the ruleset-selected copy is observed only after release. Locally I ran the workflow's two guard steps on a throwaway clone with the validators in trusted/ and a candidate that removes one managed labels resource. Without an acknowledgement the deletion guard exits 1 and names the exact line to add. With that line it exits 0. A chore: subject on a deploy/ change is refused by the release-contract guard, and a feat: subject passes. The ruleset itself (applied on the next release) is proven by reading it back and by a negative control, tracked on security(.github): enforce the deploy/ guards from a trusted ref or protected review, not from the pull request's own workflow #183.
