Handle an absent work-queue branch during dispatcher activation by Copilot · Pull Request #67104 · github/gh-aw

Copilot · 2026-10-09T04:21:06Z

The ESLint Factory Dispatcher failed during activation when the work-queue branch had not yet been created. Snapshot creation treated genuine branch absence as a missing-Policy error.

Activation: Allow an authenticated dispatcher to capture the absent queue as an empty, uninitialized snapshot. Existing policyless ledgers and worker snapshots remain errors.
Dispatcher behavior: Exit with noop when the branch is absent; do not submit or dispatch work without installed Policy.
Coverage: Add regressions for absent-branch reads, summaries, and rejection of invalid existing queues.

🟡 Changes recommended

The absent dispatcher still cannot emit the required noop because safe-output normalization rejects all unassigned-dispatcher messages.

What changed in this PR

Allows authenticated dispatchers to treat an absent work-queue branch as an uninitialized snapshot while preserving Policy validation.

Changes:

Supports absent-branch dispatcher snapshots and summaries.
Rejects existing policyless ledgers and worker snapshots.
Updates dispatcher guidance and regression coverage.

Security review found no permission or supply-chain weakening; compiler scanners were not run under review constraints.

Fixed in cb6cdb9: the safe-output append path now permits only noop for an absent dispatcher snapshot, with regressions rejecting queue-control messages, worker effects, ordinary dispatch, and existing policyless ledgers.

Updated the shared work-queue guidance in cb6cdb9 to distinguish a null-snapshot_sha absent branch from an existing policyless ledger; workers still require Policy.

Great work on the dispatcher fix for the absent work-queue branch — the regression tests are a nice touch. This looks ready for review.

@copilot address the following outstanding work in one pass:

Update this branch with the latest main using make merge-main, resolving any conflicts and preserving the intended changes.
Review (actions/setup/js/work_queue_claim_scope.cjs:142): The newly admitted absent-dispatcher scope still cannot produce the required noop. readClaimScopeContext() now returns { assignment: null, ... }, but the safe-output append path calls normalizeRuntimeMessage(), which rejects every message for an unassigned dispatcher; an absent dispatcher calling {type: "noop"} therefore throws instead of exiting successfully. Permit only noop for this absent-dispatcher state (while continuing to reject worker effects and ordinary dispatch), and cover the actual safe-output append path. - Handle an absent work-queue branch during dispatcher activation #67104 (comment)
Review (.github/workflows/eslint-factory-dispatcher.md:55): This new absent-branch behavior contradicts the shared work-queue authoring guidance at .github/aw/work-queue.md:90-92, which still says every uninitialized result is a deployment failure and not an empty backlog. Update that guidance to distinguish a null-SHA absent branch from an existing policyless ledger; otherwise future dispatcher workflows will continue implementing the old failure path. - Handle an absent work-queue branch during dispatcher activation #67104 (comment)
