Track real and synthetic focus with process-bound monitor receipts. Bind keyboard activation to the snapshot window and align targeted pointer and keyboard bursts with the reference event sequence. Wait for pasteboard data delivery before restoring the clipboard, and add focus/stream diagnostics with transition regression coverage. Validated with check:native and six covered NetEase focus cycles.
