HistoryStore.compose(boardRoot📒) returns non-optional and runs for
every session — the nil the gate produced was the only nil it ever had.
makeHistoryProvider is a one-axis decision: git-mode boards bind the git
provider, everything else native, in every tier; Session.tier stays
recorded, dormant. BoardGitSection shrinks to the four mode postures
(.absent and .proPointer die, BoardGitNote and the .git probe with them);
every board carries all three popover tabs (BoardInfoTab.available
retired); the titlebar branch shows on any git-mode board; the settings
sheet and card History section stop reading tier. InertGitTests is
repurposed as UntouchedGitTests — the file layer still never opens .git,
now load-bearing for mode-none boards. The accessibility audit reaches the
settings sheet at last: the fixture board hosts it in every tier, so the
free-fixture disabled-row test becomes an open-and-audit test.

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.
