Two review nits.

Liveness. A pushed artifact pending on a basis P stayed withheld for good when a pull supplied P as a delta: - Only MarkPending re-rooted, and only for a pushed delta. - Filling a phantom with a delta runs no cascade, so nothing judged the waiting rows if the delta was readable, or moved them to P's own root if it was not. A later fill of that root never reached them.

The fix is one hook at the choke point every received delta passes, storeDeltaContent: seedcheck.DeltaStored. - If the stored delta is readable, the rows pending on it are judged. - If not, they move to its chain root, so whatever finally resolves the chain judges them. - It replaces MarkPending's push-only re-root.

Error surfacing. JudgeFilled still skips a row whose own bytes cannot be read (a delta that does not apply or fails its checksum, or bytes that are not the artifact named) and judges the rest of the batch. Any other failure is now returned, a broken chain to the filled root included: check-in and tag return it, and the cascade logs it, as it already did for JudgeFilled errors. The separate availability skip went with it.

Tests: - A pushed plain file and control artifact pending on a basis that a pull supplies as a delta, on a held basis or on one that arrives in the next round. Both become readable and stop being withheld, are announced on a push-on, and the control artifact is linked. - A row whose content does not decompress is reported. - A checksum-failing row is skipped like an invalid one. - Each hook branch and each error class fails a test when changed. check-in: 584c55d1fd user: [email protected] tags: main, trunk

Takes the client-side announcement fix. A seed refused at the link step without a pending row (one a pull or clone completes in a later round) leaves unclustered through refuse(). A push-on from that store never names it, and a test now pins this. check-in: 9f0b995575 user: [email protected] tags: feat/horizon-dfloor-receive, main, trunk
