"""MeshBay Node — chat storage and relay.

Encryption is the client's: the node holds an epoch key it delivers to members
and never a plaintext message once a group has the switch on. See
`docs/chat-sender-keys.md`. It is not the Sender Keys ratchet this module's
docstring used to name — `senderkeys.py` is unused by production and is kept for
a possible future 1:1 DM, alongside `ratchet.py`.
