Keep a bounded FIFO of drop payloads while the startup or recovery document is not validated. Flush each payload exactly once only after the generation-checked renderer Ready signal, retain immediate delivery for a ready renderer, and discard stale payloads when the main window is destroyed or replaced.
Wire renderer block, Ready, and window-close transitions through main and cover recovery, safe failure visibility, stale Ready signals, ordered multi-drop delivery, queue bounds, lifecycle cleanup, and duplicate prevention.
