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.
