Struct Thread 

pub struct Thread {
    pub thread_id: ThreadId,
    pub leaf_id: Option<String>,
    pub journal: Journal,
    pub model: String,
    pub reasoning_effort: Option<String>,
    pub workspace: PathBuf,
    pub ephemeral: bool,
}

Durable thread (the former Session). One per conversation, persisted in state.threads. The only new field vs the old Session is leaf_id — the journal cursor — plus the typed ThreadId. All other fields keep their persisted JSON shape unchanged.

Fields

thread_id: ThreadId

leaf_id: Option<String>

Active branch tip. None before the first journal header.

journal: Journal

Journal (append-only). In-memory projection of the persisted threads/turns/items/events layout is derived root→leaf.

model: String

reasoning_effort: Option<String>

workspace: PathBuf

ephemeral: bool
