Struct PersistedSession 

pub struct PersistedSession {
    pub agent_id: String,
    pub name: String,
    pub messages: usize,
    pub created_at: Option<u64>,
    pub updated_at: Option<u64>,
}

A conversation mentra has on disk, as basis reports it.

basis’s own shape rather than a re-export of mentra’s PersistedAgentSummary, for the same reason Event is basis’s own type: what basis publishes should not move because a runtime internal did.

Fields

agent_id: String

The persisted agent id, which is also the ACP session id (ADR-0007).

name: String

The name the session was opened under.

messages: usize

How many messages the conversation holds. Zero means it was opened and never used.

created_at: Option<u64>

When the conversation was first written, in seconds since the epoch.

Optional because mentra’s summary is: a store that keeps nothing across process lifetimes has no record and therefore no answer, and basis carries that rather than inventing a number to fill the gap. Nothing reached through list_in is one of those — listing opens a file store of its own, whatever the workspace was running on — so in practice both of these arrive set. list_in’s ordering still handles None, because a rule that only works for the values it happens to see is not a rule.

updated_at: Option<u64>

When it was last written, on the same clock and absent in the same case.

This is last persisted, not last spoken: mentra rewrites an agent’s row on every turn and on every set_model, set_effort or set_name, so it moves for a rename as readily as for an exchange. Close enough to “last activity” to sort a list by, and not close enough to bill by.
