Reading as device:?
Reading as deviceEach message is sealed separately for every recipient device. Pick a device here to decrypt the transcript with that device's key — exactly what that person would see. In a real deployment only the device's owner holds its private key.

What the server actually stores?
On-the-wire envelopeThis is the raw record the server keeps for the latest message: iv (a one-time nonce), eph_pub (the sender's per-message public key), and ciphertext (the sealed bytes). There is no plaintext column anywhere — only a holder of the recipient device's private key can read the message.
