Each revision kept writes, before it is kept, the digest of the object of every entry that has a fingerprint under that fingerprint's key; the verb entry (the tools bundle) reads the key and then the object; indexer_entries reads a key and whether its object is kept. The named set (a want or a running build keeping an entry) is not built: the event wanted carries no form for a removed want. Builds: design 47 G §675 (By fingerprint, Its tools in part), §443 Claude-Session: https://claude.ai/code/session_01JG73KEq4zoDfM9WtYpcQgZ
