on branch trunk
— Merge storage: at-rest re-deltification closes most of the content-bytes gap
fossil-style best-of-N delta base selection (pickBase, plan §5) plus a `zit pack` re-deltification pass with a monotonic-shrink guard (§6.1) and same-path candidates (§6.2). At-rest only: all four RFCs conformant, wire interop preserved, every repacked frame hash-verified against the log.
Measured (whole-file, index-inclusive): sqlite: 207.3 MB -> 174.4 MB (1.40x -> 1.18x vs fossil 147.7 MB) fossil-scm: 117.5 MB -> 108.1 MB (1.63x -> 1.50x vs fossil 72.2 MB)
The monotonic-shrink guard (keep the smaller of {existing frame, re-encoding}) is what turned re-deltifying a clone of fossil-quality wire deltas into a net win instead of a +33% regression. (user: dmestas, size: 102057) [annotate] [blame] [check-ins using]

on branch cli
— Merge trunk into cli: integrate the storage pack work with the verb slice
Brings trunk bab930 (the storage branch's at-rest re-deltification / zit pack generational rewrite, plus src/pack.zig and its bench baselines) into the cli-verbs-2 slice. One conflict, in src/root.zig — both branches added a module export at the same spot; resolved by keeping both (pub const bisect and pub const pack). logstore.zig and main.zig auto-merged. Integrated tree green: 1678 unit + 376 e2e; the seven new verbs and the pack pass together. (user: dmestas, size: 102057) [annotate] [blame] [check-ins using]
