"""Auto-generated tests for Phase 1 exit criteria that require live API keys.

Per the VERIFY stage directive ("For unverifiable items: auto-generate test
scripts that WOULD verify them when keys are present"), these tests exercise the
two Phase 1 exit criteria that are pending voice-service key provisioning:

  - Exit criterion #1 (live audio session): a real WebRTC voice turn completes.
  - Exit criterion #2 (live latency measurement): R1-R4 probes produce real
    numbers and the TTS decision is finalized.

At v0.1 VERIFY time, only GITEA_TOKEN (operational) is guaranteed; the three
voice-service keys (DEEPGRAM_API_KEY, CARTESIA_API_KEY, OLLAMA_API_KEY) are NOT
provisioned in this environment. These tests are therefore SKIPPED when the keys
are absent, and will run automatically once the keys are provided via `.env` /
`.ciagent/.env.secrets` / the environment.

Run:
    pytest tests/test_pending_keys.py -rs          # shows skip reasons
    DEEPGRAM_API_KEY=... pytest tests/test_pending_keys.py   # runs the live tests

These tests are intentionally network-bound and are NOT part of the default
fast suite. They are gated behind the key presence checks so CI without keys
stays green.
