The coalesced scene delta fed into the live agent context ("What the agent sees").
Replace-current-state semantics: each entry is the item's CURRENT state, not an edit log.
When reset is true the items array replaces the agent's entire view of the board
(emitted after undo/redo/load, or when the journal no longer reaches the caller's token).
