Check-in [6681b95432]

zit applied every erratum in its draft text and retired docs/rfcs/erratum/ at check-in 62a7d1bb3f. Each draft records its corrections in its own Changes appendix, so the suite stops pinning and reading erratum files: the "# erratum" pin lines, the parser branch that accepted them and conformance/rfcs/erratum/ are removed, and comments that named an erratum file cite the draft section instead.

The artifact-format, repo-state, sync-protocol and delta-format drafts are byte-identical at 62a7d1bb3f. The sub-manifest draft is re-pinned; it differs only in its expiry date, reflow, and the dropped pointer to the erratum files. The sparse-cone draft is re-pinned to the 19 October 2026 revision on zit's horizon-rfc branch (0acb5e185c, its merge of 62a7d1bb3f): section 3.6 is removed and section 3.4 states the literal prefix rule once, so SC-3.6-1 becomes SC-3.4-3 (a metacharacter is a literal character, never expanded, and the member may be refused), covered by the same case, renamed sparsecone.3.4.metachar. The refresh script copies the -01 texts to their -01 names and takes the horizon-rfc drafts from a second checkout. check-in: 3e1f791160 user: [email protected] tags: feat/submanifest-reader, main, trunk

The store cone (draft-fossil-sparse-cone-00 §5) is kept in a storecone table that exists only while a cone is set. fossil rebuild drops tables it does not know, so losing the cone reads as dense and the store heals toward dense (§5.2). A cone that does not parse also reads as dense.

LoadAbsences sorts every phantom into transit, shunned or elided by zit's rules. A phantom is elided when F cards name it only outside the store cone and no held delta uses it as a base. check-in: 524c749185 user: [email protected] tags: feat/submanifest-reader, main, trunk

A zit older than check-in 0431958ff4 gates trees on the announced version, so against it the interop tests fail on the protocol change rather than on anything go-libfossil does. zitBinary now probes the binary for the pragma's name, which a zit that sends it carries; zit's version cannot tell, since 0.5.0 was tagged before the change. An older zit is skipped with its path, version and the check-in needed, or fails the run under REQUIRE_ZIT_BIN=1 as a missing one does.

Tracked in #452. check-in: b9c7364ff2 user: [email protected] tags: feat/submanifest-reader, main, trunk
