Implement

Treat the selected spec folder as the complete settled handoff. If approved task files exist under tasks/, implement them sequentially in dependency order. Otherwise implement spec.md directly.

After an actual interruption, reconstruct progress from the spec folder, Git, diff, and tests, then continue the remaining work. Confirm ownership before incorporating ambiguous dirty changes.

Complete each outcome and its acceptance criteria with focused verification. When task files exist, check their acceptance criteria, mark finished tasks completed, and record verification evidence. Where commits are expected, commit code, tests, and the task update together as a meaningful checkpoint.
