Enforce FileAsync's registration and notification state guards, and TTY.mu ownership of controlling-terminal associations. Distinguish direct waiter-entry access under regMu from the waitable's own synchronization. Preserve registration lock ordering and signal delivery after releasing FileAsync.mu, while leaving TTY's signal-delivery lock scope unchanged. Assisted-by: Codex
