Extract now runs fossil's repo-cksum check after materializing: a present R card is compared with the aggregate over every file the manifest names, read from the store, so a sparse checkout over a dense store reaches the same verdict as a dense one, and a sparse store skips the check. Like fossil, a disagreement is a warning delivered through ExtractOpts.Warn and never fails the extract; repo-cksum off disables it. The conformance case builds its repository with fossil and checks fossil warns exactly where go-libfossil does. Clears the SC-4.3-4 scope note. check-in: 318f46de9e user: [email protected] tags: feat/submanifest-reader, main, trunk

A sparse store refuses a clone its cone does not cover unless the boolean partial-mirror repository setting is on, read as fossil reads a boolean setting. It reaches HandleSync, XferHandler, ServeHTTP and repo serve alike; libfossil.SettingPartialMirror names it. Closes SC-5.3-2. check-in: 6012d82bd6 user: [email protected] tags: feat/submanifest-reader, main, trunk

The public entry point refuses a dense store, as zit's pack --drop-elided does, and drops exactly the blobs that only out-of-cone F cards name. The test computes that set from the held artifacts, then verifies the store and recovers every dropped payload by widening through SetConeContext. check-in: 774f579bfa user: [email protected] tags: feat/submanifest-reader, main, trunk

A cone-excluded row is charged at its expanded size plus card overhead, so a round over a long excluded run stops where a dense batch would and the cursor resumes it, instead of walking the whole run in one round. SC-6.2-1 stays partial: ordinary keep-set discovery still reads the whole store. check-in: 1da7f0f002 user: [email protected] tags: feat/submanifest-reader, main, trunk

Many check-ins sharing one wide sub-manifest cross the 1<<20 visit bound at depth two; 1023 roots are served and 1024 are refused the way depth 17 is. Clears the SC-8-2 scope note. check-in: 8652936469 user: [email protected] tags: feat/submanifest-reader, main, trunk

Widening a sparse-store checkout with a peer fetches and materializes exactly the newly covered payloads; with no peer it refuses naming the elided class and changes nothing; a peer lacking the content is refused with the unavailable artifact named. Clears the SC-3.5-2 scope note. check-in: fcb7f90f2c user: [email protected] tags: feat/submanifest-reader, main, trunk

The sparse-store entry said nothing yet fills a store sparsely and the sparse-checkout entry said a merge touching an uncovered file is refused; both are no longer true on this branch. check-in: 7720f39cd0 user: [email protected] tags: feat/submanifest-reader, main, trunk

The checkout lane's review blockers are fixed and re-reviewed, so the two scope notes now name only what is unverified: durable crash recovery of the private marker, a conformance case for reverting a record-only change, and stash apply on a sparse checkout. check-in: 7163d16293 user: [email protected] tags: feat/submanifest-reader, main, trunk

Only managed revert steps reach it, each with a resolved path, so the fallback for an empty path was dead code standing in for a broken invariant. check-in: a3cc82b191 user: [email protected] tags: feat/submanifest-reader, main, trunk

Record-only merge steps return before the content switch, and a both-changed path outside the cone is refused, so storeMergePayload had no production caller. Its tests called it directly; they go with it, and the merge-failure test keeps its vmerge assertion. check-in: dac73e55c9 user: [email protected] tags: feat/submanifest-reader, main, trunk

A partial commit wrote every pending change outside the cone into the check-in. Such changes now behave as disk changes do: a full commit records them, a partial commit leaves them pending against the new version, and a partial commit is still refused while a merge is pending. Fossil-oracle tests cover the dense analog of each case. check-in: 802906e3b8 user: [email protected] tags: feat/submanifest-reader, main, trunk

After the observed generation changes, every request falls back to dense and the service never re-prepares. Say so where the type is documented, so a caller does not expect sparse serving to resume after a foreign commit. check-in: 322c8ef406 user: [email protected] tags: feat/submanifest-reader, main, trunk

Preparation counted newlines in every artifact against the 1M card budget, so a repository holding one large multi-line text file was refused far below its byte limits. Only an artifact with a verified Z card can parse as a deck, so only those are charged cards and parsed; the byte budgets still bound all content. check-in: 2f0f64f464 user: [email protected] tags: feat/submanifest-reader, main, trunk

The prepared index left private and shunned RIDs out, so a gimme for an in-cone private artifact failed keeps() and got no reply, where the dense handler sends the private igot. A client never told the artifact is private can keep requesting it. The index now answers cone membership only, as the dense keep-set does; the handler's live private and shun gates decide visibility, so no payload is exposed. check-in: 87f44dbf99 user: [email protected] tags: feat/submanifest-reader, main, trunk

Fossil's update leaves vmerge alone, so the next commit records the merge parent. The sparse update cleared vmerge, losing the parent and letting a partial commit through while the merge was still pending. check-in: 5a070508db user: [email protected] tags: feat/submanifest-reader, main, trunk

The fallback that explains a parent whose tree the store does not hold ran under context.Background, so a cancelled commit still paid for it. Commit passes its context; snapshot, which has no deadline, says so explicitly. check-in: c25e714b08 user: [email protected] tags: feat/submanifest-reader, main, trunk

The closure walk parsed a node before checking whether its frame had been visited, so a tree whose S cards name one sub-manifest many times parsed it once per reference: a 616 KB node took 0.46s at 50 references and 3.7s at 400. The visit and byte limits bound what is held, not that work, and a caller without a deadline could wait for days inside the budget.

The walk is its own function now, parsing through a callback it calls at most once per (artifact, baseline) pair, so a test can count parses. check-in: 6824f7701a user: [email protected] tags: feat/submanifest-reader, main, trunk

Propagate tags and apply scheduled leaf rechecks before each link transaction commits. Preserve sparse metadata repair, pretagged merge-parent rechecks, and rollback-safe retries. Tracked in #432. check-in: b38bf23f79 user: [email protected] tags: feat/submanifest-reader, main, trunk

Use same-branch and arrival-order evidence for leaf validation, validate parent overrides, and match Fossil parent tokenization. Preserve sparse readiness and delta-tree scans within one verification snapshot. Tracked in #433. check-in: 35672aadc7 user: [email protected] tags: feat/submanifest-reader, main, trunk

Keep Fossil's mandatory operation-less second round without accepting any cleanup payload or clearing the refusal. Exercise dense and sparse refusal alongside the existing client compatibility cases. check-in: a453db484d user: [email protected] tags: feat/submanifest-reader, main, trunk

Exercise mixed held and nested missing S siblings after clearing and rebuilding derived tables. Repeated compaction preserves holdings and elided identities; ordinary sync must not request the rebuilt elided artifacts. check-in: 29a11b0aa8 user: [email protected] tags: feat/submanifest-reader, main, trunk

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
