"""End-to-end tests for ALL 58 SDK sample demos.

Tests every sample in six modes:
1. TestAllSamplesWithMockedSDK -- mocked Stratix client (all 58)
2. TestAllSamplesLiveAPI -- real API via subprocess (all 58, @pytest.mark.live)
3. TestOpenClawOfflineMode -- --no-sdk flag (11 OpenClaw demos)
4. TestWithoutAPIKey -- graceful failure without credentials (all 58)
5. TestMissingDependencies -- optional-dep fallback (integration, openclaw, copilotkit)
6. TestSampleCompleteness -- verify test lists match disk

        are ``.gitignore``d). CI provides the key as a real env var.

        Asserts that the LLM, given the documented system prompt and a
        ``confirm_judge`` frontend tool declared on the AG-UI input,
        calls (in order): ``list_recent_traces`` -> ``list_judges`` ->
        ``confirm_judge``, then halts at ``confirm_judge`` waiting for a
        resolve. Run lifecycle is clean (one RUN_STARTED, one
        RUN_FINISHED with matching runId, no RUN_ERROR).

        This is the test that proves the architectural rewrite (#2 in
        the rollout plan) actually works against a real LLM, not just
        against mocks.
