Add the annotate command: per-line provenance over the version chain
zit annotate PATH — which check-in introduced each line of one tracked file at the current checkout, and when. One canonical spelling (no blame/praise). The engine walks the file's full-ancestry version chain (repostate.ancestorsOf, the same 3.3 walk merge-base/bisect use; per-version content via Repository.fileAt, the one 8 effective-set query), diffs adjacent versions with the one house line-diff core (merge3.matchLines), and pushes each line's origin back to the OLDEST version carrying it. Across a merge, a line in ANY parent side is charged to that parent (primary first, repo-state 3.2), never to the merge; the merge is charged only for lines in no parent version. Output: 10-char hash, ISO date from event mtime, the line verbatim; a binary file refuses exit 1. Reviewed adversarially (merge attribution hand-traced correct). 1673 unit + 352 e2e green. check-in: f774a1a2a7 user: dmestas tags: cli | |

Track src/bisect.zig — omitted from the bisect commit 343d41b2f3
The bisect check-in landed every edited file but not the new bisect.zig itself (committed without a prior add), so that check-in would not build from a clean checkout. Add the file; no code change. check-in: b937bca55b user: dmestas tags: cli | |

Deepen log with an optional PATH: fold finfo into one verb
zit log CHECKIN [PATH]. With no PATH, behavior is byte-identical to today. With PATH, the ancestry walk emits only the check-ins that CHANGE that path: a check-in K changes PATH iff PATH's effective content (via Repository.fileAt, the one artifact 8 effective-set query — no CLI-side F-card re-derivation) differs from PATH's content in K's PRIMARY parent (first-listed P card, repo-state 3.2). Presence flips count (root add, delete, rename departure/arrival as delete+add, no old-name following); equal hashes are no change; a phantom parent reads as absent. walkLog gained an optional filter; the null path preserves the shipped DFS verbatim. The finfo/log split was historical accident, not design — one deep log replaces a shallow sibling, no new verb. 1661 unit + 343 e2e green; fmt clean. check-in: 6a360f33ff user: dmestas tags: cli | |
