Struct ChannelLiveness 

pub struct ChannelLiveness {
    pub last_send_at_ms: Option<i64>,
    pub last_send_ok: Option<bool>,
    pub last_error: Option<String>,
}

A point-in-time snapshot of one channel’s outbound-send health, recorded by the send path (U3) and read by messaging.status (U2). All fields are Option/bool so a never-sent channel reports cleanly (no send recorded).

Fields

last_send_at_ms: Option<i64>

Unix-epoch milliseconds of the most recent send ATTEMPT that produced a recorded outcome (success or failure). None until the first send.

last_send_ok: Option<bool>

Whether the most recent recorded send succeeded. None until the first send; Some(false) for BOTH a hard error and a soft sent:false.

last_error: Option<String>

Human-readable reason for the most recent FAILURE (hard error string or the soft sent:false reason). None when the last send succeeded or no send has happened. NOT cleared to None on success — instead a success sets last_send_ok:true and clears it; see Self::record_success.
