The builder's tools bundle serves reserved given a package's name: it follows the catalog half's packages view itself, finds the module from the name, answers the reserved version, or for a version no reservation holds asks the seat mesh-catalog's versions and answers released with the release's digests; a name no entry carries, two entries carry, or a version neither reserved nor released is answered error. builder_versions by name calls reserved through its invokes. The builder's process serves no call. Builds: design 47 G §572, §582 (A-70) Claude-Session: https://claude.ai/code/session_01NcbgfGKaxw984XyAPfLm4h
