Overview
Comment:repocache: a hit rewrites a stale or missing image (zit#180)

A cache whose image is absent or at an old layout replayed the record body on every fast_read open, since only a miss stored. The hit now serializes the image from the view it just built and stores it, so the fallback is paid once.

info: render Q cards from the state, not the manifest (zit#177)

The crosslink record, the state and the image now carry each check-in's Q cards (sign and target), so the cherrypick/backout line needs no manifest read. Record format 4, image layout 7. info NAME 16 ms to 6 ms on libspatialite, level with leaves; output unchanged. check-in: adb05cc14e user: dmestas tags: trunk

timeline: read the image, not a full derive (zit#181)

The image has carried adjacency since layout 2 and comment/login since layout 6, so every default row renders from the zero-parse path; only full/-v/-p still read manifests. 60 ms to 8 ms on a 22k check-in store, output byte-identical across formats. check-in: 18ffce5678 user: dmestas tags: trunk
