Struct JournalEntry 

pub struct JournalEntry {
    pub sequence: u64,
    pub timestamp: DateTime<Utc>,
    pub agent_id: AgentId,
    pub iteration: u32,
    pub event: LoopEvent,
}

A journal entry for durable execution.

In Phase 2, entries are emitted via the JournalWriter trait. The default implementation is BufferedJournal which retains entries in a bounded in-memory ring buffer for observability. Phase 5 adds DurableJournal backed by SQLite/Postgres.

Fields

sequence: u64

Monotonically increasing sequence number.

timestamp: DateTime<Utc>

When this entry was created.

agent_id: AgentId

The agent this entry belongs to.

iteration: u32

The iteration this entry was created in.

event: LoopEvent

The event recorded.
