- Move TransactionLedger + types from @excalidraw/element into
  packages/excalidraw/transaction.ts (no external consumers)
- Move commitSyntheticIncrement from App passthrough to Store directly,
  fix didAppStateChange to use Delta.isRightDifferent instead of
  presence-check, and replace isolated increments queue with direct
  scheduleMicroAction + flushMicroActions
- Remove commitSyntheticHistoryEntry from App, expose store and
  createTransaction on AppClassProperties instead
- Replace O(N) deep-copy snapshot in updateScene with shallow map copy
  (element refs are safe — ledger ignores index, the only in-place
  mutated prop, and deep-copies only recorded elements)
- Merge ledger + manager tests into single transaction.test.tsx
- Update dev-docs to reflect new file structure

+# Transactions
+
+Transactions let many live scene updates render immediately while still committing a single durable history entry.
+
+Typical use case:
+
+- AI streaming emits many `NEVER` updates for real-time feedback.
+- Those updates advance the live scene and store snapshot, but do not create undo history.
+- A transaction records the intended logical delta separately, then commits one synthetic durable increment at the end.
+
+## Key Files
+
+### `packages/excalidraw/transaction/`
+
+- `transaction.ts`
+  - `Transaction` is the per-tx instance.
+  - `updateScene()` applies live updates with `captureUpdate: NEVER`.
+  - `updateElements()` is a typed partial-patch helper over `updateScene()`.
+  - `commit()` builds synthetic snapshots and commits one durable entry.
+  - `cancel()` ends the tx without committing history.
+- `ledger.ts`
+  - `TransactionLedger` keeps per-element baseline, target, and touched props across tx steps.
+  - `buildSyntheticSnapshots()` reconciles tx intent with the live scene using `live-wins-per-prop`.
+- `undoOverridePlanner.ts`
+  - Tracks tx intermediate values.
+  - Produces undo override candidates for regular user history entries that were recorded while a tx was active.
+- `manager.ts`
+  - Owns tx lifecycle state and active-tx priority.
+  - Injects tx undo markers into durable deltas at record time.
+  - Resolves effective history deltas at undo/redo time.
+- `diff.ts` / `types.ts`
+  - Shared diff helpers and transaction-specific types.
+
+### `packages/element/src/store.ts`
+
+- `store.commitSyntheticIncrement()`
+  - Builds `StoreSnapshot -> StoreChange -> StoreDelta` from logical before/after snapshots.
+  - Commits the synthetic durable increment immediately through an isolated path.
+  - Does not flush unrelated pending micro actions.
+- `StoreDelta.markers`
+  - Carries extra history markers such as `txUndoOverrides`.
+
+### `packages/excalidraw/history.ts`
+
+- `onBeforeRecord()`
+  - Lets the transaction manager attach markers before a durable delta becomes a history entry.
+- `setEffectiveDeltaResolver()`
+  - Lets the transaction manager rewrite a history delta at undo/redo time before it is applied.
+
+## Flow
+
+1. Caller creates a transaction.
+2. `tx.updateScene()` applies live updates with `NEVER`.
+3. The ledger records net element changes; appState intent is accumulated separately.
+4. Regular user durable edits that happen while the tx is active may receive tx undo markers.
+5. `tx.commit()` asks the ledger for logical before/after snapshots and calls `store.commitSyntheticIncrement()`.
+6. Undo/redo later uses the manager's effective-delta resolver to decide whether ended tx markers should patch the baseline of a regular history entry.
+
+Result:
+
+- live rendering stays immediate;
+- one tx still produces one durable history entry;
+- interleaved regular edits can undo back to the correct pre-tx baseline.
+
+## Undo Examples
+
+### Interleaved Regular Edit
+
+1. Baseline: `rect = (x: 0, stroke: black)`
+2. Tx updates it live to `(x: 200, stroke: red)` with `NEVER`
+3. User makes a regular durable edit: `(x: 200, stroke: purple)`
+4. Tx commits; live stays purple
+
+The user history entry was recorded while the tx was active, so its local baseline is `red`.
+If undo later runs after the tx has ended, restoring `red` is wrong: the correct pre-tx baseline is `black`.
+
+To fix this:
+
+- record-time attaches a tx undo marker to the user history entry
+- perform-time checks whether the tx has already ended
+- if ended, the effective delta is patched so undo restores `black` instead of `red`
+
+### Active Tx vs Ended Tx
+
+Using the same example:
+
+- if the user undoes while the tx is still active, the marker stays inactive and undo restores the tx intermediate value (`red`)
+- if the user undoes after the tx has ended, the marker becomes active and undo restores the pre-tx baseline (`black`)
+
+So markers are recorded early, but applied conditionally.
+
+## AppState
+
+Elements use ledger snapshots. AppState does not.
+
+The transaction instead keeps:
+
+- `initialAppState`: observed appState at tx start
+- `accumulatedAppState`: merged caller intent from `tx.updateScene({ appState })`
+
+At commit, the transaction computes the final appState patch and passes it into `store.commitSyntheticIncrement()`.
+
+## Example
+
+```ts
+const tx = app.transactionManager.create();
+
+tx.updateScene({ elements: updatedElementsA });
+tx.updateScene({ elements: updatedElementsB });
+tx.updateElements({
+  elements: [
+    { id: "rect-1", type: "rectangle", updates: { strokeColor: "#f00" } },
+    { id: "rect-2", type: "rectangle", updates: { x: 120 } },
+  ],
+});
+
+tx.commit();
+```
+
+## Notes
+
+- `commit()` and `cancel()` are idempotent.
+- `updateScene()` and `updateElements()` throw after the tx has ended.
+- Conflict handling inside synthetic snapshots is fixed to `live-wins-per-prop`.
+- Multi-tx interleaving is supported through manager-owned lifecycle tracking and active-tx priority.

- * The inputs in this block intentionally VIOLATE the (soft) invariant that a
- * frame's children — and a group's members — are contiguous in the elements
- * array. Such states shouldn't occur in normal use, but they CAN arise from
- * bugs or broken input, because nothing re-defragments element order during
- * a reorder (`normalizeElementOrder` only runs on duplication). We keep these
- * tests so the reordering ops stay exercised against malformed order.
- *
- * HARD CONTRACT (a failure here is a real bug): a reorder must never throw,
- * duplicate, or drop elements. `assertReorderPreservesElements` checks this.
- *
- * SOFT SNAPSHOT (read before "fixing"): the exact resulting ORDER is NOT a
- * contract for invalid input — it's whatever the slice math happens to
- * produce. If a future change alters an `expected` order below, that is NOT
- * necessarily a functional regression. First confirm from the diff that the
- * hard contract still holds (nothing duplicated/lost), then update the
- * expected order to match, provided it's deemed an improvement over the
- * previous order, or it's an acceptable change given the underlying logic
- * change.

 ### Breaking changes
 
-- Theme changes initiated by the default UI are now delegated to `<Excalidraw onThemeChange={(theme) => ...} />` when supplied. If `onThemeChange` is not supplied, light/dark theme toggling still falls back to updating the internal editor state.
-
-  - `MainMenu.DefaultItems.ToggleTheme` no longer accepts the item-level `onSelect` callback. Host apps that need to control light/dark/system theme should pass `onThemeChange` to `<Excalidraw />` instead.
-  - `MainMenu.DefaultItems.ToggleTheme` with system theme support now uses `allowSystemTheme` together with `theme={Theme | "system"}` only to render the selected value. For the regular light/dark item, pass `allowSystemTheme={false}`.
-  - `CommandPalette.defaultItems.toggleTheme` was removed. The default theme command is now rendered by the command palette itself when `UIOptions.canvasActions.toggleTheme` enables the action (see below).
-  - `UIOptions.canvasActions.toggleTheme` still controls default theme UI availability. When it is `null`, it defaults to `true` if `props.theme` is omitted or `props.onThemeChange` is supplied, and otherwise defaults to disabled.
-
 - Renamed the `excalidrawAPI` prop to `onExcalidrawAPI`.
   - `onExcalidrawAPI` is now called on mount (instead of during constructor), and later on unmount (with `null` value). The API may be removed altogether in the future (you can use `onMount` & `onUmount` to manage the `ExcalidrawAPI` object (e.g. to cache it to a global state), already).
