description	DRAFT — pick up and deliver one delivery/tasks/ work contract under the six-sigma protocol (deterministic selection, TDD, allowlist discipline, author≠verifier). Use when asked to "take the next task", "work the board", or deliver a specific task id. Full mechanization lands with W1 (work next) and W2 (sandbox provisioning).

Phase runner (draft — manual protocol until W1/W2 land)

1. Read the protocol once: delivery/README.md. It is binding; this skill is its checklist.
2. Select: open delivery/board/BOARD.md, take the TOPMOST item in READY. Never choose.
3. Claim: move its line to CLAIMED (· <agent> · <ISO date>), append a claimed line to delivery/board/LOG.md, commit chore(delivery): claim <ID> BEFORE working.
4. Sandbox: git worktree add .worktrees/<ID> -b feat/<ID> main (contract sandbox: worktree). Work only inside it. Never restart services a live run depends on.
5. Read ONLY your contract (delivery/tasks/<ID>.md). Insufficient contract = log blocked: contract insufficient — <missing> and stop. Never improvise scope.
6. TDD, in order: failing test (run it, observe red, commit) → implement → green → refactor. Name tests after the contract's Scenario: lines. Respect the allowlist and budget.
7. Verify: run the contract's verify command until exit 0 from a clean tree. Lint/format touched files. Validate contracts changed: node scripts/gates/w0.mjs.
8. Hand off: move the board line to VERIFY + append ready-for-verify to LOG (honest deviations included), commit on main. You may NOT move your own task to DONE — a fresh clean-checkout session with a distinct identity re-runs the gate (README rule 7).
9. Blocked twice = stop. Append blocked with the exact error and what you tried.

Log format: <ISO-ts> | <task-id> | <event> | <agent> | <note> — append-only, never edit history.
