  • Commit Message: feat(merge): implement closed-chain queueing and queue-head selection
  • Branch: feat/merge-chain-closed-queue

Background and Context

Closed merge-chains are queued in FIFO order awaiting validation against master. Only the queue head is validated at any given time. This serialization at the queue level is intentional: it ensures that only one batch is validated against the latest master at once, preventing race conditions while still allowing multiple PRs to be batched together.

Parent Epic: #9757

Expected Behavior

When this issue is complete, closed chains are enqueued in FIFO order, the queue head is selected deterministically, only one chain is validated at a time, and queue state is persisted.

Acceptance Criteria

  • Closed chains are queued in FIFO order
  • Queue head selection is deterministic (oldest closed chain is always head)
  • Only one chain is validated at a time (no concurrent validation)
  • Queue state is persisted across restarts
  • Unit tests cover FIFO ordering, head selection, and persistence

Subtasks

  • Design the closed chain queue data model
  • Implement FIFO enqueue logic for closed chains
  • Implement deterministic queue head selection
  • Implement mutual exclusion to prevent concurrent validation
  • Implement state persistence for the queue
  • Write unit tests for FIFO ordering, head selection, and concurrency guard
  • Commit implementation on branch feat/merge-chain-closed-queue

Definition of Done

This issue is closed when:

  • Closed chains are queued in FIFO order with deterministic head selection
  • Only one chain is validated at a time
  • Queue state persists across restarts
  • Unit tests pass with coverage >= 97%
  • A pull request is submitted, reviewed, and merged to master
  • All acceptance criteria above are independently verified
