Package buildsignal implements the build poll loop.

Package cancel implements the orchestrator-side cancel controller.

Package dlq contains controllers that consume messages from per-topic dead-letter queues and reconcile the affected request and batch entities into a terminal failed state.

Package merge implements the trigger stage for the asynchronous merge.

Package mergeconflictsignal consumes merge-conflict check results from runway's signal queue, correlates them to the request by the echoed id, and either advances the request to the batch stage (mergeable) or fails it (conflicted).

Package mergesignal consumes merge results from runway's merge-signal queue, correlates them to the batch by the echoed id, and transitions the batch to a terminal state — Succeeded when runway merged the batch, Failed when it could not — then fans the batch out to conclude (so member requests pick up the outcome) and speculate (so dependents can re-plan).
