| 09:40 | Add a persisted derivation cache so repo-state verbs skip re-deriving all of history: cache the crosslink inputs keyed on the append-only log's tail and replay them on a hit, cutting a warm 'zit leaves' on a 130k-artifact repo from ~103s to 0.21s with byte-identical output and a full rebuild on any log change or corruption. check-in: e1f401fa0d user: dmestas tags: trunk | |
| 09:38 | Document that a cache hit skips whole-log integrity, so interior bitrot preserving size and tail is served until a rebuild — deleting .zit-cache restores full detection. closed check-in: 31e140ddbc user: dmestas tags: cache | |
| 09:28 | Memoize the derived repo view in a disposable .zit-cache sidecar so read-only verbs answer sub-second at fossil scale instead of rescanning the whole log on every invocation. check-in: 08504d5f5d user: dmestas tags: cache | |
