Server-side shape enumeration per bound repo — one archive download via the forge adapter, definitions extracted with a Python mirror of the write-path hook's awk rules (shared test vectors pin the two together) — compared against recorded snippet locations by path+symbol. Summary is cached in the settings KV with a freshness stamp; recomputed on webhook push (spawned off the delivery path) or explicit refresh, never in a request path. Surfaces: GET/POST /api/projects/<id>/coverage[/refresh], a project-page card (estimate-labeled, largest-gaps chips), and a one-line evidence-carrying entry in enter_project read from cache only.
