Struct PooledAgent 

pub(crate) struct PooledAgent {
    pub handle: Arc<AgentHandle>,
    pub account: AccountKey,
    pub permission_mode: Option<PermissionMode>,
    pub registration: Option<Registration>,
    pub session_id: String,
}

Pool entry wrapping the live Arc<AgentHandle>, the account key the subprocess is bound to, the permission mode that spawn resolved for its project, and the session registration a respawn re-sends.

Fields

handle: Arc<AgentHandle>

account: AccountKey

The account the subprocess is bound to, resolved at spawn.

permission_mode: Option<PermissionMode>

The permission mode this session spawned with, from its project; None when the spawn resolved to no project and the launcher default applied. The dispatch path reads it to stamp the same mode onto /new and /resume re-spawns.

registration: Option<Registration>

The session’s registration, captured at spawn; a /new or /resume respawn re-registers it so the fresh child gets a fresh binding and env set.

session_id: String

The id the child currently runs under, as its spawn resolved it and as Connected refreshed it. The slot is the pool’s key; this is the occupant the CLI knows, and what a caller holding only the slot needs for a CLI argument or a transcript path.
