repositorySetting opened the store with a bare openReadOnly -- a full frame-header scan to reach one config frame, 5.6s on a 1.17M-artifact store, and blind to the .zit-cache scan index because it had no directory in hand. It now takes Repository.logStore's own fast path: adopt the persisted index, resume over the tail, refresh on miss, with the cache directory resolved through the checkout's store pointer so a worktree never grows a stray sidecar. 5.6s to 0.12s. check-in: cf01ef34ba user: dmestas tags: trunk
