Function open_episodes 

pub fn open_episodes(root: &Path) -> Vec<Episode>

The open episodes of one checkout, as the store holds them.

Read from .ai/local/state/sessions-open/, which is a file per provider session rather than a singleton: an episode used to be one session-current.yaml per checkout, and a second provider session opening one was folded into the first. Measured in this repository on 2026-09-09: seven concurrent sessions, one record between them.

last_sign_of_life is the later of the episode’s started_at and the newest ledger line it stamped, which is what makes “nobody has been here for a day” a measurement rather than an inference from the open record’s own age.
