| Comment: | fix(sync): label the parents of every held manifest at a structural horizon
A structural clone holds the manifests of the held set and everything they reach through B and S cards (draft-fossil-horizon-00 §5.1), so a delta manifest's baseline below C is held. Its parents were labelled by nobody: boundaryOf took the parents of K's check-ins only. The clone then classified such a parent as transit and requested it, and the origin, which withholds manifests below C, never sent it; the clone stalled with one phantom outstanding. zit's origin has the same gap (sparse.zig 758-783), and zit's author agreed the draft will define a boundary hash as an unheld parent of any manifest the clone holds. boundaryOf now labels the parents of K and of every check-in the reach holds. The regression is the HZ-3.1-4 case for a delta manifest in K whose baseline lies below C: the clone completes, the baseline is held but not a leaf, and K's check-ins derive the dense repository's tags. |

Merge branch 'wip/hz-memo' into feat/horizon-cones
The origin's classification memo (draft-fossil-horizon-00 §6.2): the reference graph and each cone's classification kept per store prefix and extended by appended artifacts, recomputed in full only when an arrival was already cited. A pull after a one-artifact push on fossil-scm.org's repository answers in about 0.25 s instead of 2.7 to 4.5 s. check-in: 7dec3e4fb3 user: [email protected] tags: feat/horizon-cones, trunk | |
