Prepare, structure, and validate a component/service specification pack so it is ready for architecture/technical design and epic decomposition. Use when you need to (1) create or improve component/service docs, (2) migrate existing scattered docs into a recommended structure (either move-only or content refactor), (3) track readiness against a checklist (critical/needed/desirable), (4) maintain open questions and an "inbox" for unstructured notes, and (5) keep docs change-by-change in Git with a detailed changelog entry per important commit.
