title: 100-turn runtime parity soak

scenario:
  id: runtime-soak-100-turn
  surface: runtime
  runtimeParityTier: soak
  coverage:
    primary:
      - runtime.long-run-stability
    secondary:
      - runtime.long-context
  objective: Provide an optional long-run soak that can be scheduled or run in Testbox without entering the maintainer default gate.
  successCriteria:
    - The same QA session accepts 100 sequential user turns.
    - Every turn receives the requested marker reply without losing session state.
    - Runtime parity captures token estimate or live token usage for the full soak cell.
