Look up, trace, and create spec requirements, and bootstrap a new SPEC.md.

Graduate the winning candidate from the spec-driven `implementations/<version>/<n>-<name>/` tree to the sole implementation at the repo root — a one-way move, only once one candidate has clearly won.

Scaffold a new candidate implementation in the spec-driven `implementations/<version>/<n>-<name>/` tree, to stress-test the spec against a fresh stack.

Refresh STATUS.md to match current spec coverage — the lightweight, hook-safe ledger writer in the spec-sync family.

Reconcile SPEC.md and the source — full-domain coverage + drift analysis, applied as one-way syncs.
