ws-implementlisted

Implement the work described by the user in the spec or tickets. Use /ws-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 /ws-code-review to review the work. Commit your work to the current branch. ## Graph node - **Tier:** user-invoked (entry) - **Reads:** the spec or ticket being built (tracker issue or `.scratch/` file), the pre-agreed test seams, `CONTEXT.md`, ADRs - **Emits:** the working implementation committed to the current branch; typecheck and full test suite green; review findings addressed before the commit - **Edges:** - then → ws-tdd at the pre-agreed seams (worker: one red-green vertical slice at a time) - then → ws-code-review before committing (worker: two-axis Standards + Spec review of the diff) - **Edge rule:** entry → worker only, never entry → entry — a continuation that lands on another entry node is a user-mediated handoff (recommend it; never auto-invoke it). - **Handoff protocol:** the work lands as commits on the current branch; close out on the driving ticket and reference it by id (DONE|{branch@commit}).
