| 06:13 | Speed up repo-state derivation on open: replace the O(N-squared) crosslink scans with parent/child/tag adjacency indexes, verify each frame's whole-frame CRC once at scan instead of twice per verb, and cache delta bases during the derivation sweep — cutting the algorithmic crosslink term over 100x with byte-identical derived state. check-in: baa7053ee1 user: dmestas tags: trunk | |
| 06:11 | Assert a read-only-verified store is never appended to: the append frame path skips the redundant whole-frame CRC only because openReadOnly proved it at scan, so appending to such a store would leave a frame unchecked. closed check-in: 7c3d36865e user: dmestas tags: scale | |
| 06:00 | Accelerate repo-state derivation on open: replace the quadratic crosslink scans with per-parent/child/rid adjacency indexes, verify each frame's CRC once at open instead of again on every read, and memoize delta bases across the derivation sweep, so the query verbs stay fast on large repositories without changing any derived answer. check-in: 76b0f8f1d0 user: dmestas tags: scale | |
