title: Empty-response retry budget exhausted

scenario:
  id: empty-response-retry-budget-exhausted
  surface: runtime
  coverage:
    primary:
      - runtime.empty-response-recovery
    secondary:
      - runtime.retry-policy
  objective: Verify repeated empty GPT turns exhaust the retry budget after one continuation attempt.
  successCriteria:
    - Scenario is mock-openai only so live lanes do not pick it up implicitly.
    - The agent performs the replay-safe read that makes retrying allowed.
    - Mock trace shows the run reaches a terminal post-read turn without ever producing the requested success marker.
  docsRefs:
    - docs/help/testing.md
  codeRefs:

    - src/agents/embedded-agent-runner/run/incomplete-turn.ts
  execution:
    kind: flow
    summary: Verify empty-response retry exhaustion still surfaces a visible failure.
    config:
      requiredProvider: mock-openai
      promptSnippet: Empty response exhaustion QA check
      prompt: "Empty response exhaustion QA check: read QA_KICKOFF_TASK.md, then answer with exactly EMPTY-EXHAUSTED-OK."
      retryNeedle: The previous attempt did not produce a user-visible answer.
