Build the semantic commit-message engine
CommitMessageEngine replaces the interim composer as the wired default: a pure total function from two snapshots + changed paths to a message. Full vocabulary — Add / Delete / Move / Rename / Edit / Restyle / Resize / Reorder over cards, lanes, board; Attach / Remove; Repair for the duplicate remint (detected as a heal-classed rename-paired arrival whose id the previous snapshot never held — the loader withholds duplicates, so the shape is a bare arrival); the trash triple by diff shape alone (into .trash = Delete, out = Restore, leaving the tree = Permanently delete); Relabel / Assign / Set due date plus the named generic for custom keys. Plural folding with shared destinations, implied events as body bullets never subjects, ~40-char subject truncation, "(untitled)". Bookkeeping (sequence-preserving renumbers, stamps, backfilled kind) composes nothing. Non-snapshot paths compose path-shaped events — CLAUDE.md reads "Update agent guide (vN)" via the marker line (the m10 card's deferred bullet lands here), everything else "Update '<path>'". The comment verb family per 01's ruling (comments shipped, so 06 gains the verbs): Comment on / Edit comment on / Delete comment on / Draft comment on / Permanently delete comment on '<card>', grouped one event per comment folder, classified ahead of the model-silence rules, card title resolved from either snapshot. GIT_DELTA_ADDED is surfaced as GitChangedPath.isArrival — post vs edit is unanswerable from snapshots that exclude comments by ruling. A card moving with its thread swallows the comment events (implied-events one level down). The previous snapshot is HEAD's tree, materialized per flush into a temp dir (index.md blobs in full, other blobs zero-byte — the model reads attachment names, never bytes) and re-parsed through the one BoardLoader; never a value carried forward. changedPaths is a hard filter per split commit, which also earns the stage-around and kills phantom events. Launch catch-up and foreign windows compose through the same engine. 48 new tests (35 pure + comment family + engine-level); 2293 tests / 394 suites green; InertGitTests untouched.
