| Comment: | repostate: carry the C-card comment in the crosslink record
An unlimited timeline re-read and re-parsed every manifest just to print its comment first-line — 163k inflate+parse cycles on pkgsrc. The comment now rides the crosslink record into the derived state (commentOf; image backing falls back to the manifest read), so the render loop is a lookup per row: full timeline 12.3s -> 1.06s. Record-format consumers bumped so old bodies miss instead of misparsing (repocache v3, checkpoint v2 — one re-derive per repo, then warm). zit log's pinned B-log-1 walk untouched. |

checkpoint: one-pass build, incremental advance, opportunistic refresh
Build paid a bypass derive, a whole-prefix delta scan, and a capture re-derive; a view-free captureRecords (byte-identical to the deriving walk, pinned at every boundary) now does capture and delta detection in one pass, and an existing sidecar's body plus its delta-free attestation reduce a rebuild to the unscanned tail. pkgsrc: cold build 17:58 -> 4:21; rebuild or anchor advance -> 5.1s. Repository.open's healing paths keep an existing checkpoint fresh: witness shape forced (the automatic path can never mint an artifact, whatever §8.1 says — a tree pin advances by demotion and is re-pinned deliberately), gated on 4MB growth AND anchor progress so blob-only growth never churns the sidecar. No checkpoint, no auto-creation: building once is the opt-in. check-in: adae602908 user: dmestas tags: sub-manifest | |

repocache: persist the content log's scan index
The lazy content channel re-walked every frame header on each open — O(store) before the first byte of any comment, cat, or annotate. The scan's product (entries, hash index, shun rows, config cursor, tail key) now persists as .zit-cache/index, self-validating and LogKey-keyed: an exact tail adopts whole, a grown log resumes the walk over the tail alone, and anything else falls back to the authoritative scan (--no-cache never consults it). pkgsrc: info 1.7s -> 0.44s, timeline -n 5 4.3s -> 0.96s. check-in: f2bfd36e74 user: dmestas tags: sub-manifest | |
