Struct Ack 

pub struct Ack {
    pub message_id: MessageId,
    pub reader: Address,
    pub acked_at_unix_ms: u64,
}

Per-reader acknowledgement. Dedup key is (message_id, reader), never the message alone – a room-addressed message has one ack per reader, not one total. Ported from HarnessMailAckV1.

Fields

message_id: MessageId

reader: Address

The exact address that acknowledged: a session’s own address if a session acked, the account’s if an account did – so two sessions of the same account track their own read state independently, the way Matrix scopes read markers to a (user_id, device_id) pair rather than to the account alone.

acked_at_unix_ms: u64
