| Comment: | 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. |

pack: trust profitable at-rest deltas; no-op an unchanged log
Re-beating every existing delta paid best-of-N delta.create plus a zlib trial per artifact and never converged -- each run re-encoded ~100k frames again for ~16 bytes each (#122). A delta whose declared raw length clears pickBase's own 75% bar is copied verbatim; one that fails it (a peer's poor base) still re-encodes. A .zit-cache/packed generation key makes a repeat pack over an unchanged log a no-op. tk: 121.6s -> 76.7s first pack, 0.2s repeat. check-in: 27c4f30036 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 | |
