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.

Every settled change on a git-mode board commits, debounced 2s past
drag/typing churn, staged whole-root with .gitignore respected.
GitCommitOperation reaches the vendored libgit2 directly (same 1.9.2
pin SwiftGitX resolves — importable, not duplicated) for
signature-capable commits; add-git's config materialization is gone,
identity resolves at commit time (repo-local config, else derived
default) per the 2026-07-31 ruling in 06. CommitAttribution
classifies per file off EchoLedger receipts: user identity on
app-mediated windows, Lanework External <[email protected]>
on foreign, the modified-by refinement (<slug>@agents.lanework
.invalid) when every foreign file agrees, heal-marked receipts split
into their own commit — window split foreign → heal → user.
Edit-session granularity: ~700ms saves stay uncommitted, staging
excludes open session folders (closure-resolved so mid-session moves
stage around the new location), session end nudges the debounce so
each session lands exactly one body commit. Flush-before-overwrite
gates on known-foreign windows and commits synchronously ahead of
the write; close/quit flush the pipeline via CloseFlushCoordinator's
committerFlush. index.lock backs off briefly then re-debounces
silently; clean tree no-ops; genuine failures ride the standing
history-suspension banner and retry next debounce. Abnormal repo
states (detached HEAD, merge/rebase/cherry-pick in progress) hold
the engine with a 15s re-check; unborn HEAD commits "Initial board
state" whole-tree; dirty tree at open catches up through the same
engine. Message seam (CommitMessageComposing) ships interim — the
semantic composer is the next card.
Discovery diffs HEAD against an in-memory index with rename
detection (git status alone never pairs a bare mv), and a failed
survey reads as "could not look", never "nothing changed".
46 new tests / 8 suites, all real repositories via bundled libgit2.
2240 tests / 383 suites green; InertGitTests untouched.
