implement

Implement the work described by the user in the spec or tickets. Claim the tickets you are working on.

Use $ponytail ultra as a strict guideline. Use $tdd where possible, at pre-agreed seams. If doing user-facing changes always verify the entire flow end-to-end with a browser, iOS simulator or Android emulator.

Run the full check suite (typechecking, linting, tests) once at the end as per repository guidelines.

Once done, run $implementation-review on the work.

Commit your work to a new branch from the current base.
