implement

Implement the work described by the user in the spec or tickets.

Use /tdd where possible, at pre-agreed seams.

Run typechecking regularly, single test files regularly, and the full test suite once at the end.

Once done, use /review-axes to review the work. Since nothing here is committed, give it the unstaged working tree as its fixed point: a ref-based diff would come back empty. Do not mark acceptance-criteria checkboxes (- [ ] / - [x]) in the spec or tickets yourself, /review-axes syncs those after the Spec review based on what the code actually did.

Never make a commit. Generate a Conventional Commits message ≤300 chars for the user: type(scope): imperative summary + blank line + short why-body.
