8///
9/// - `Public` (v0.1): server stores plaintext. Anyone can read; any signed
10///   agent can write.
11/// - `Private` (v0.2+): MLS-encrypted. Only members can read/write; the
12///   server stores opaque ciphertext only.

30/// Message type discriminator.
31///
32/// - `Text` (v0.1): plain UTF-8 text in `content`.
33/// - `MlsApplication` (v0.2): base64url-no-pad MLS PrivateMessage in
34///   `content`. Server stores opaque; only members can decrypt.
35/// - `MlsCommit` (v0.2): base64url-no-pad MLS Commit in `content`.
36///   Group state change. Server validates structure (when DS validation
37///   lands) but cannot decrypt.
