stat: buffered census walk, indexed config read
The census pread 10 bytes per frame -- an O(frames) syscall floor, ~150k calls on tk (#121). A 64KB read-ahead window keeps the walk a measured physical pass at ~1/40th the syscalls, and the config/roll read adopts the scan index like every other cached verb. tk stat: 0.234s -> 0.026s, now ahead of fossil info. Output byte-identical. check-in: c17e0233ca user: dmestas tags: trunk | |

diff/status: adopt the scan index for the baseline open
CheckinBaseline and the extras-family config read each paid a full frame-header scan per invocation (#120). A shared openLogAdoptingIndex adopts the .zit-cache sidecar (#112's pattern), refreshing on miss; extras' path is read-only per B-extras-16. tk single-file diff: 0.220s -> 0.020s. check-in: be281ab760 user: dmestas tags: trunk | |

sync client: log-backed holdings replace the whole-store snapshot
pull/push/sync loaded every artifact into memory before the first wire byte -- 3.7GB resident on a 148k-artifact store, OOM beyond it (#119). The client now sits on LogIndexStore as serve does: names, held/phantom, shun mask, and hash-policy off the frame index, content materialized per-rid on demand, received artifacts in the appendix. No-op pull on tk: 3.7GB -> 88MB, 64s -> 13s. check-in: 46d49702f7 user: dmestas tags: trunk | |
