ci: guard the same files on main that pull requests guard - #13789

Conversation
A workflow that filters both events writes its input list twice, and the two copies can disagree without either pull request seeing it. Two already have: ci-artifact-transport.yml guards nine paths on pull requests and not on push, and cmux-skill-contract.yml omits a test its own job runs. web-complexity.yml diverges on purpose -- a pull request must not be able to queue the job that runs its own edit -- so it is declared in EXEMPTIONS with a reason rather than left looking like a typo. An exemption whose workflow no longer diverges is an error, so it cannot go stale. The guard lives in testbox-broker-guard.yml, which deliberately carries no path filter of its own: a parity check over path filters cannot be gated by one.

ci-artifact-transport.yml listed 21 paths under pull_request and 12 under push, so nine files were checked on pull requests and unguarded on main. Four of the nine are test files the job itself executes, and tests/test_ci_selective_layer_wiring.py reads .github/workflows/ci-macos.yml and asserts on its contents -- so a push to main that broke the selective layer wiring ran nothing. The push list is the wrong one: it omits inputs the job demonstrably reads. cmux-skill-contract.yml had the same shape at one path: its job runs tests/test_cmux_settings_jsonc.py, which only the pull_request filter named. Both push lists now match their pull_request lists, and tests/test_ci_workflow_path_filter_parity.py fails if they drift apart again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…text (#13788) test_ci_executes_review_fabric_contracts grepped scripts/ci/detect_linux_guard_changes.py for each review-fabric path as a literal string. #13775 made the guard routes derived from PATH_OWNERS and from ci-guards.yml's run: lines, so those literals are no longer in the file and the test fails on a clean main -- taking preflight, Guard status, linux-preflight, tests and ci-status down with it on every pull request routing that lane. The routing is intact; only the check was stale. Assert the behaviour instead: the path must route linux_guard_tests, and groups_for_path must explicitly own it with preflight. That second assertion uses groups_for_path rather than classify_test_groups because classify_test_groups falls open to every group for an unknown path, and so would keep passing if ownership were dropped.

Three claims in the inventory were wrong, found while implementing the rows they describe. Row 2 listed `ci.yml` as a display-name dependency of merge-group-fail-fast.yml. It is not: that reference is `actions/workflows/ci.yml/runs`, a file path, which is already stable. Only the `workflow_run` trigger names a workflow by display name. The row also said deriving it was impossible; a test can pin the trigger against the producer's own `name:`, which #13793 does. Row 8 called `release_only_jobs` a set of job names. They are job ids: the surrounding code partitions on `\njobs:\n` and splits on the YAML keys, so a display name never participates. Row 4's deferral reason estimated that syncing the path lists would make "nearly every push to main" run the workflow. Measured against this checkout it is 11 of 67 merges, and the expensive half stays gated. #13789 implements the row. Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

ci-artifact-transport.ymllisted its inputs twice: 21 paths underpull_request, 12 underpush. Nine files were guarded on pull requests and unguarded on main.The
pushlist is the wrong one, and the job's own steps show it rather than the list's length:Test transport and fallbackruns seven test files, and four of them appear only underpull_request.tests/test_ci_selective_layer_wiring.pyreads.github/workflows/ci-macos.ymland asserts on its contents, so a push to main that broke the selective layer wiring ran nothing at all.cmux-skill-contract.ymlhad the same shape at one path: its job runspython3 tests/test_cmux_settings_jsonc.py, which only thepull_requestfilter named.Resulting behavior
Both
pushlists now match theirpull_requestlists, andtests/test_ci_workflow_path_filter_parity.pyfails if any workflow's two filters disagree again. Duplicating the correct list into both triggers is what was already there, so the list is no longer the thing being trusted — the guard is.The test lives in
testbox-broker-guard.yml, which deliberately carries no path filter of its own. A parity check over path filters cannot itself be gated by one.Deliberate divergence goes in
EXEMPTIONSwith a reason. One entry exists:web-complexity.ymlomits its own path frompull_requeston purpose, because that job runs contributor-controlled package install scripts and a pull request must not be able to queue the job that would run its own edit.tests/test_web_complexity_trusted_workflow.pyalready enforces that boundary from the other side; the parity guard caught the asymmetry and that test explained it. An exemption whose workflow no longer diverges is an error, so it cannot go stale.A YAML anchor would have been the smaller change, but GitHub Actions does not expand anchors in workflow triggers, so the equality test is the mechanism available.
On the cost of syncing
docs/ci/derived-not-declared.md(row 4) left this unimplemented because the nine missing paths includeci.yml, "so syncing the lists makes nearly every push to main run this workflow." Measured on the 67 merges to main in this checkout (all 2026-09-22): the currentpushlist matched 1, the synced list matches 11. That is 16%, not nearly every push.The added runs are also the cheap half of the job.

A push that touches onlyci.ymlruns checkout plus sevenpython3/bashtests and skipsnpm ciand wrangler entirely.Validation
tests/test_ci_workflow_path_filter_parity.pyfails at the first commit naming both drifted workflows and their exact paths, and passes at the second.

The guard covers
push/pull_requestpath filters only. The related duplications indocs/ci/derived-not-declared.md—ci-cache-receipts.yml's ten paths written twice and currently in sync (row 4's twin), andworkflow_guard_groups.PATH_OWNERS— are untouched here.ci-cache-receipts.ymlis now covered by this test, so it can no longer drift silently.Part of #13095.

Guards the same files on main that pull requests guard. The
pushpath filters ofci-artifact-transport.ymlandcmux-skill-contract.ymlnow match theirpull_requestfilters, so nine files that were checked on pull requests but unguarded on main now run on merge — including four of the seven test files the transport job runs andtests/test_ci_selective_layer_wiring.py, which reads.github/workflows/ci-macos.ymland asserts on its contents, so a push that broke the selective layer wiring previously ran nothing.Adds
tests/test_ci_workflow_path_filter_parity.py, which fails if any workflow's two filters disagree. The guard runs intestbox-broker-guard.yml, which deliberately carries no path filter of its own so the parity check cannot be gated by one. The check treatspathslists containing negated!patterns as order-sensitive, since a negated path can exclude and later re-include a match. Deliberate divergence goes inEXEMPTIONSwith a reason;web-complexity.ymlis exempt because a pull request must not self-queue the job that runs its own edit, and an exemption whose workflow no longer diverges is an error. Additionally,ci.yml'ssuite-coveragegate gets atimeout-minutes: 5bound so a hung coverage computation fails instead of running indefinitely.On the cost of syncing
docs/ci/derived-not-declared.mdleft this unimplemented because it estimated the synced list would run the workflow on nearly every push. Measured on 67 merges to main, the syncedpushlist matches 11 (16%) instead of 1, and those runs are the cheap half: a push touching onlyci.ymlskipsnpm ciand wrangler entirely.Written for commit c0905be.
