The ceiling when there is no deadline to narrow to is the longest execution any plan permits (90 minutes); E2B rejects a create above the session length its plan allows, which is 1 hour on Hobby and 24 hours on Professional. `PI_SANDBOX_LIFETIME_MS` may lower that ceiling but has a **31-minute minimum**; lower values are raised to the minimum. A run that outlives the sandbox loses its work before the push, and an orphaned sandbox — one whose Sim process died mid-run — bills until the lifetime expires, which is why that lifetime tracks the deadline.
