Timeline

Use raw cone references while independently verifying held bytes. Preserve leaves and nonterminal paths so missing descendants keep their range proofs. Exercise missing S nodes, stale derived indexes, and cancellation after an observed demotion. check-in: 55b3ca7155 user: [email protected] tags: feat/submanifest-reader, main, trunk

zit check-in 68a3f76cb7 renames the artifact-format, repo-state and sync-protocol drafts from -01 to -00 in their headers, cross-references and reference entries, and retitles each Changes appendix "Changes in This Revision". No normative text changed and no section number moved.

The pinned copies take zit's file names, the requirement tables pin the new hashes, and the comments, tests and docs that cited the -01 drafts cite the -00 ones. The refresh script copies every draft under its own name. The sparse-cone copy is re-pinned to d497c2432f, whose text is unchanged. Coverage counts are identical before and after. check-in: 245a0ed306 user: [email protected] tags: feat/submanifest-reader, main, trunk

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

zit clones go-libfossil's flat history through a cone, and both sides must report the same number of elided phantoms over the same cone. Each side then commits over its sparse store and pushes to a dense store of the other. The commit carries no R card, and the receiver holds the whole check-in. check-in: 0a63c3b22f user: [email protected] tags: feat/submanifest-reader, main, trunk

Cases elide out-of-cone blobs from a dense clone, as a cone-scoped clone would leave the store. They check the three absence classes, the client and server sync filters, recomputation on a cone change, loss of the cone (unreadable, or dropped by fossil rebuild, after which fossil's pull heals the store), verify and rebuild counts, R-card omission and skipping, a commit over elided subtrees pushed to a dense peer, widening, hybrid histories, and delta bases.

Holding out-of-cone sub-manifest nodes is recorded as a deviation from §5.1. zit holds them too, because a tree that cannot be enumerated never links.

A checkout's record names the phantom for a file that neither cone covers, so a checkout opens over a sparse store. check-in: b907b41650 user: [email protected] tags: feat/submanifest-reader, main, trunk

The client's phantom load and the server's request_phantoms skip elided phantoms (draft-fossil-sparse-cone-00 §5.2). A dense store classifies nothing and behaves as before. Repo.StoreCone and Repo.SetStoreCone expose the store cone. check-in: 37f15485b4 user: [email protected] tags: feat/submanifest-reader, main, trunk

A commit over a store with a store cone leaves out the R card (draft-fossil-sparse-cone-00 §4.3). It refers to out-of-cone files the store lacks by hash alone (§5.3). VerifyRCard skips over a sparse store, and skips a manifest that has no R card, since an absent R card is not damage.

verify.Report gains Phantoms (transit) and Elided. Neither is an Issue, so a store complete within its cone verifies OK (§5.2). Rebuild keeps the store cone and reports the same counts. check-in: cd98ba38cb 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
