transaction Operations that actually committed after policy and bounds filtering.

transaction: Transactioninterface Transaction {
  patches: DocumentOp[];
  epoch?: number;
}interface Transaction {
  patches: DocumentOp[];
  epoch?: number;
}interface Transaction {
  patches: DocumentOp[];
  epoch?: number;
}Low-level Store transaction. epoch provides optional optimistic concurrency at the storage boundary. Calling Store.applyTransaction bypasses Grid read-only checks and Grid undo/redo history. Host-driven edits should use Grid.applyTransaction.API reference →;

changes Cell-level before/after effects; empty for commits that only change metadata.

changes: CellChangeinterface CellChange {
  addr: CellAddress;
  oldValue: CellValue;
  newValue: CellValue;
  oldStyle?: CellStyle;
  newStyle?: CellStyle;
}interface CellChange {
  addr: CellAddress;
  oldValue: CellValue;
  newValue: CellValue;
  oldStyle?: CellStyle;
  newStyle?: CellStyle;
}interface CellChange {
  addr: CellAddress;
  oldValue: CellValue;
  newValue: CellValue;
  oldStyle?: CellStyle;
  newStyle?: CellStyle;
}One committed cell edit, carrying enough to roll back.API reference →[];

commitReason What produced this commit — see CommitReason.

commitReason: CommitReason;

source Remote input is observable but never belongs in outgoing local persistence.

source: OperationSourcetype OperationSource = "local" | "remote";type OperationSource = "local" | "remote";type OperationSource =
  "local" | "remote";Whether a committed change originated locally or from remote host input.API reference →;

epoch Store epoch after the commit; emitted store and grid changes include it.

epoch?: number;
