Work With PR — Full PR Lifecycle

You are executing a complete PR lifecycle: from isolated worktree setup through implementation, PR creation, and an unbounded verification loop until the PR is merged. The loop has three gates — CI, review-work, and Cubic — and you keep fixing and pushing until all three pass simultaneously.

Phase 0: Setup         → Branch + worktree in sibling directory
Phase 1: Implement     → Do the work, atomic commits
Phase 2: PR Creation   → Push, create PR targeting dev
Phase 3: Verify Loop   → Unbounded iteration until ALL gates pass:
  ├─ Gate A: CI         → gh pr checks (bun test, typecheck, build)
  ├─ Gate B: review-work → 5-agent parallel review
  └─ Gate C: Cubic      → cubic-dev-ai[bot] "No issues found"
Phase 4: Merge         → Squash merge, worktree cleanup
