A want that names a node in kept-on, for an artifact its parts name, is fetched through kept-artifact of that node's build seat and read as an object on the bus, checked against the digest; with no kept-on it is fetched from the store, and the builder's builds are read no more (the apply hook, the fetch and the object read from bc8fbc7, its node and fingerprint from the want). Builds: design 47 G §271, §526, §421 (A-50) Claude-Session: https://claude.ai/code/session_01NcbgfGKaxw984XyAPfLm4h
