The seams unbind — the provider is always native, and the git stack compiles dead

Step 4 of strategy/01-git-excision.md, the entangled one: AppModel's makeHistoryProvider collapses to the native provider (the seam stays injectable per the reversibility posture), the session's git state and its wiring go (wireGitUndo, wireBranchSwitching, the card-session staging threading), BoardStore sheds commitSeam and the identity-history ranker (the loader's nil-safe rung now tops out at birth date — today's no-git behavior), SessionSettleGate keeps the gate and inherits the path utility it borrowed, BoardRegistry drops the persisted operation stamp (decode-safe), and the git banner family leaves BannerCenter with its announcer and accessibility phrases. One missed harvest tie severed (the narrator's root subject is its own now). Nothing outside Kanban/Git/ references the stack — proven by sweep. 2,855 tests green.
