— Merge feat/seed-receive-drop; re-pin horizon draft to zit caeef421ee
Re-pins draft-fossil-horizon-00 to zit trunk check-in caeef421ee (file artifact ab18fa7f89), which changes §5.2.2, §5.2.3 and §6.2.3 and adds two Appendix C bullets. This brings in the local feat/seed-receive-drop branch, which implements the receive rule, and resolves it against main (#477 chain-walk bounds, #478 seed binding).
§5.2.2, the seed's D (tracked in #479): - Mint dates a seed at max(tagxref.mtime) over every row in the repository, cancels and propagated rows included, as zit's latestTagEvent does. It was the latest of the rows the seed summarizes. - A cancel of the newest tag, or a reopened closed branch, therefore no longer mints a seed earlier than the one a clone holds, which the clone's D floor refused as a replay.
§5.2.3, the receive rule: - A pull, clone or sync drops a seed by this store's label or by a binding card when it can read it, and the link step refuses one completed later. - The draft also requires that a delta kept without its base, pushed or received, is not announced or served while it cannot be expanded. feat/seed-receive-drop only withheld pushed ones. The pending mark moves into storeDeltaContent, so a pull marks too, and a clone marks what is still unreadable when it ends (seedcheck.WithholdUnreadable). That avoids judging every dangling file delta of a clone a second time. - Since #478 minted seeds carry a binding card. The seed-shaped-ordinary cases therefore strip it, and a new test checks that a seed with the card is never linked.
Conformance rows: - HZ-5.2-2 takes the new D text. - HZ-5.2-4 loses the old ordinary-artifact sentence. - HZ-6.2-6 says the D is fixed by the repository's tag events. - New rows: HZ-5.2-14 (the receive-path drop; PARTIAL, since a seed completed in a later round is kept inert, and was counted when its delta arrived), HZ-5.2-15 (the dropped-hash record) and HZ-5.2-16 (withholding unexpandable deltas). - New cases: two D cases mirroring zit's "horizon seed date" regression, a cancel on C and a cancel at an ancestor below it, and five receive cases. - The deepen-floor case now replays an older seed, since an honest origin no longer mints one.
