| Comment: | feat(horizon): a check-in graph a held set extends over
An origin computes K for every horizon request by reading every plink edge and held check-in from the store. draft-fossil-horizon-00 §6.2 asks it to read those references once into a graph keyed to the store prefix and extend that graph by the artifacts appended since. Graph is that graph: loaded once, extended copy-on-write by the rids that changed, and HeldSet over it equals HeldSet over the store. |

feat(content): an origin classification memo extended by appends
An origin re-reads its store for every horizon request: the reference facts behind the path classification and the trees of the whole held set. draft-fossil-horizon-00 §6.2 asks it to keep the classification keyed by cone digest and store prefix, extend it by the artifacts appended since, and recompute in full only when an arrival carries a name a held P, B or S card cited while it was absent. Memo keeps the store's cone-independent references (the reference facts, the check-in graph and the dangling P/B/S names) at a prefix, and per cone digest and per horizon the classification over them. A view extends each by the appended and filled rids: the loader's decisions for those rids alone, classification of the facts' new tails, and the tree walk of the check-ins K gained. Anything other than an append or an uncited fill (a cited arrival, a deleted or phantomized row, a first tree) reads the store in full. Views are copy-on-write and reach the memo only when published, so a rolled-back request leaves nothing behind. check-in: e5bdac3d33 user: [email protected] tags: feat/horizon-cones, trunk | |
