Overview
Comment:feat(sync): never request a sparse store's elided phantoms

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.

test(conformance): cover the sparse store's step-3 requirements

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

feat(manifest,verify): commit over a sparse store, and count absences

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
