Artifact 341009e699c8e82d0616d59c36a987100cd2df2fa95d0e38dafd63dc1705ffae:
packLog takes a borrowed Filter; a dropped rid is not copied, PackStats.dropped counts it, and packVerifyShunned refuses to swap in a store still holding a digest the filter was told to remove. keep_all is the identity, so every other caller behaves as before.
The check runs BEFORE reconstruction and before the SS7.7 verify. A shunned artifact may be unlawful or simply broken, and verifying it would abort the very operation meant to remove it. Two tests pin the ordering: one frame whose content no longer hashes to its name, one that will not decode at all. The second closes a hole the first left in deriveCandidateHints.
putArtifactPacked's floor_span became optional. A delta whose base the filter dropped has no keepable frame, and 'I have no floor' is a different claim from 'my floor spans N bytes'; an in-band sentinel could not tell that from a miscomputed span.
pack_help no longer overclaims: damaged CONTENT does not block the reclaim, a damaged CHECKSUM still does, because the open-time pre-flight covers the whole store before any reclaim runs.
Merges S5's e2e block alongside this slice's. Fossil's suggested resolution would have dropped this one. by dmestas on 2026-07-30 00:39:18.
