GitHistoryProvider is the second HistoryProviding implementation:
its stack IS HEAD's first-parent ancestry, reseeded on load (redo
empty), re-synced to HEAD before every crossing so agents'
self-commits become the top and ⌘Z steps back exactly one commit;
any arriving commit clears redo (a heal-only window deliberately
does not). Restores are forward commits through the ordinary
signature path — GitRestoreOperation materializes only the
current-vs-target diff as working-tree writes and resolves no
reset/checkout symbol at all; heal commits are transparent
in-session (pointer passes over, restores exclude heal-owned paths,
identity carried on landed windows via PlannedCommit.kind →
GitLandedCommit). Subjects "Undo:/Redo: <crossed subject>"; menu
labels never nest in-session; the root commit is not a step
(crossing it would restore the empty tree).
Provider binding flips: makeHistoryProvider(store, tier, git) —
free binds native everywhere, Pro binds the git provider on git
boards and NOTHING on mode-none/repo-nested (the pair disables
through existing validation); add-git mid-session live-binds via
HistoryStore.didAddGit → bindHistoryProvider (the flip only ever
adds).
SessionSettleGate is the reusable Save All / Discard / Cancel step:
restores whose diff touches an open Edit session or raw-source
buffer gate on it (Save All applies with validation — a refused
buffer cancels the whole restore focused on the offender; Discard
reverts via CardBodyEditSession.discardBuffer and reconciles against
the working tree, deliberately skipping the second flush); untouched
sessions ride through undisturbed. Built for the branch-switch card
to reuse. BoardStore gains the async performWholesale sibling.
CardHistorySection fills the m6 EmptyView slot: read-only, newest
first, follows the card across lane moves by folder-component match
(the UUID is the identity — no rename detection), absent off git
mode and off Pro.
2332 tests / 403 suites green; InertGitTests untouched.

The chooser completes its three tiers: bundled by template order, then
keyed user templates, then keyless boards by display name — and a
malformed user template still lists, by folder name with the loader's
own sentence on the row, never failing its neighbours. The store is
re-scanned on every presentation and on app activation, the Reveal
round trip made honest without watching a folder 09 deliberately
leaves unwatched; Reveal lives in the chooser's header and mints the
store on first press. Save as Template repeats Duplicate's sequence —
progress row with Cancel, flush, detached cancellable copy — through
the engine: mint the store, read the next user order before the copy
can count itself, Finder-ladder the name, copy excluding .git and
.trash/, then stamp the whole template: mapping on the landed copy
through updateIndex, with no bracket because the copy lives outside
every watched board. Folder attributes deliberately don't carry — the
one lock the command stays live under is the read-only-DMG one, and
carrying its mode bits would mint a read-only template in the user's
own store; the command gates instead on the real hazard, unsaved card
content. A signpost names the template only when the ladder renamed
it. One name ladder now serves Duplicate and the store.

The welcome window becomes the real thing: Xcode-style, hidden title
bar with background drag, branding and actions left, recents right —
rows carrying the board symbol, name, location, and the registry's
cached lane/card counts (stamped at close, never a scan at welcome
time), sorted by last opened. Launch failures surface row-level per
02: a failure joins its recents row as a warning caption, an
unresolvable bookmark renders unavailable with Forget its one
affordance, and only a failure with no row to carry it falls back to
a compact list; a board opening again heals its row. New Board
(Opt-Cmd-N) opens the Pages-style template chooser — shipped with
the single Basic template and the m9 seams marked — flowing through
the save panel into createBoard/createLane and straight into a board
window. Open Recent gains its submenu with Clear Menu (byte-identical
to forgetting every row, pinned by test), and File > Duplicate forks
the frontmost board to a Finder-style copy sibling: pending work
flushes first through the close flush's step two alone (sessions stay
open — 09's stated exception), every GUID and tombstone carries (the
whole-board carve-out from copies-remint), and the copy opens in its
own window while the original stays put. 36 new tests.

Four scenes (welcome, restore bootstrap, board group, card group) with
system restoration disabled in favor of the registry's open-now flags:
set when a window actually opens, cleared only on user close, so quit —
and crash — leave exactly the restoration set behind. AppModel joins
windows to sessions (shared store, registry record, card refs, held
security scope); CloseFlushCoordinator pins 02's strict close order as
a seam-injected machine (card sessions end, windows drain, store
flushes, record stamps, teardown) with named slots where m6/m7 flushes
land. HostedWindowController proxies — never replaces — SwiftUI's
window delegate to intercept windowShouldClose for the flush, report
frames, and place saved frames onto live screens. Card windows are
(board path, case-folded card id) values: reopen focuses, and a
snapshot-pure fate function dismisses on delete, tombstone, tombstoned
lane, or cross-board move.
