Add the bisect command: DAG binary search for a defect-introducing check-in
zit bisect bad NAME | good NAME | next | status | reset. Marking bad/good moves the checkout to the next probe automatically (fossil parity); next re-announces it; reset restores. The candidate set (full-ancestry ancestors of bad minus the good ancestor-sets minus skipped), the lower-median probe by ascending event-mtime with hash tiebreak, and the culprit are ONE general-purpose repostate query RepoState.bisectSpan, composed from collectAncestors / mergeBaseOf / isAncestorOf / mtimeOf / hashOf per the RESOLVED bisect-midpoint rule (repo-state 2/3.2/3.3/8.3) — the CLI never walks ancestry. Bisection state is checkout-local in .zit-bisect on the undo.zig state-file tier (atomic write + fsync, magic/CRC frame, corrupt -> exit 1), in the never-tracked/extras set; probe/culprit/reset moves go through the journal-armed update.applyCheckin behind requireCleanTree. Refusals (inverted marks, unrelated histories) exit 1. 1661 unit + 339 e2e green; fmt clean. check-in: 343d41b2f3 user: dmestas tags: cli | |

Add the artifact command: the plumbing window over the one parser
zit artifact HASH [--raw] — zit's cat-file/whatis. No flag: a whatis summary (hash, structural type per artifact 5.1/5.3, size, one line per A..W card in stored order, and the 6.2 Z self-checksum verdict). A blob reports type file, size, and binary-or-not. --raw emits the verbatim stored bytes. Resolves a 4-64 hex prefix over the LogStore (ambiguous -> exit 1), reads via the existing 7.2 blob path. Everything shown comes from the ONE existing artifact parser — refactored into frameNoZ/frame/assemble with a Z-tolerant parseWindow — never a CLI-side re-parse. 1649 unit + 335 e2e (13 new B-artifact) green; fmt clean. check-in: f477c3bf19 user: dmestas tags: cli | |

Add the amend command: mint display-metadata tags, never rewrite history
zit amend NAME [--comment TEXT] [--user NAME] [--date ISO] [--branch NAME] mints ONE control artifact whose T cards change how the target check-in displays — comment, user, date, and the repo-state 6.2 branch-move set — retargeted at the check-in hash, never '*'. History stays append-only: the original manifest is untouched and a new control artifact is crosslinked in (artifact 4.7.16 T / 4.7.5 D / 4.7.17 U / 4.7.19 Z; repo-state 4/5 crosslink, 5 tag propagation). Display is honored through a new general RepoState.activeTagValue / Repository.override consumed by timeline and info. Also removes amend from the git-reflex rejection table: teaching against fossil-semantics amend with the immutability lesson conflated it with git's history-rewriting amend — amend is in fact the proof of zit's immutability, not a violation. 1643 unit + 322 e2e (15 new B-amend) green; fmt clean. check-in: 6c6d1babc2 user: dmestas tags: cli | |
