History (and later sync) is a provider behind one protocol boundary, bound per board session at composition from the entitlement:
- **HistoryProviding** — the undo/redo substrate. **The provider follows the board** (re-ruled 2026-07-31): gitless boards bind the native undo stack (13-native-undo.md: NSUndoManager over inverse `WriteOperation`s) in every tier — an upgrade never removes undo — while Pro binds the git provider on git boards (06-history-undo.md: undo as forward restore commits over HEAD's first-parent ancestry); repo-nested boards bind none. Teams inherits Pro's. Add-git swaps native → git mid-session by the branch-switch discard-and-reseed precedent (13).
- **HistoryProviding** — the undo/redo substrate. **The provider follows the board** (re-ruled 2026-07-31): gitless boards bind the native undo stack (13-native-undo.md: NSUndoManager over inverse `WriteOperation`s) in every tier — an upgrade never removes undo — while Pro binds the git provider on git boards (06-history-undo.md: undo as forward restore commits over HEAD's first-parent ancestry); repo-nested boards bind native too (re-ruled 2026-07-31 — the stack touches no git, so what matters is the absence of *app-managed* git, and the upgrade story is exceptionless). Teams inherits Pro's. Add-git swaps native → git mid-session by the branch-switch discard-and-reseed precedent (13).
- **Sync/tracker providers** — deferred with Teams; the reserved schema keys and the one-way file flow (02-architecture.md) are the format-level seam already in place.
What is shared across providers (settled): **06's Undo routing is tier-independent** — focus decides text-undo vs board-undo; only the substrate behind board-undo differs. The command surface is identical (⌘Z/⇧⌘Z, dynamically retitled menu items — both providers use NSUndoManager's title rewriting); menu titles draw on the same semantic vocabulary (06 ▸ Commit messages). A user subscribing (or lapsing) relearns nothing.
