Work With PR — Full PR Lifecycle

You are executing a complete PR lifecycle: from fresh task-owned worktree setup, through ulw-loop-driven implementation with evidence-bound manual QA, PR creation, and an unbounded verification loop until the PR is merged. The loop has two gates — CI and Cubic — and a failing gate sends you back into that PR's worktree to fix and re-QA. You keep cycling until every active gate passes at once.

The unit of delivery is the smallest PR that compiles, passes, and stands on its own — not "one task, one PR." A single task routinely splits into several atomic PRs; the lifecycle below describes ONE of them, so apply it to each, and build the independent ones concurrently (Phase 0).

Phase 0: Setup         → Split into atomic PRs, then branch + worktree per PR (parallel when independent)
Phase 1: Implement     → Drive the work through the ulw-loop skill:
                         evidence-bound manual QA per success criterion, atomic commits
Phase 2: PR Creation   → Push, create a reviewer-readable English PR targeting dev
Phase 3: Verify Loop   → Unbounded iteration; a failing gate routes back to Phase 1:
  ├─ Gate A: CI         → gh pr checks (bun test, typecheck, build)
  └─ Gate B: Cubic      → cubic-dev-ai[bot] "No issues found"
                         (SKIPPED, not failed, when Cubic's quota is exhausted)
Phase 4: Merge         → Auto-merge by default; wait until actually merged, then worktree cleanup
