# Alpha paired validation

Run the complete Assistant suite with `PYTHONPATH=src:<Lab candidate root>`.
`tests/test_alpha_pair.py` exercises the real adapter, context, orchestration,
transcript selection and generation persistence with mocked audio preparation,
Whisper, diarization and model responses. It covers de/en, all performance
profiles, anonymous generation, mapped regeneration, glossary provenance and
immutable history. The test skips when Lab is unavailable; a release validation
must run it with Lab available and report no skips.

Run Lab's full `python -m unittest discover -s tests` at its candidate revision.
History tests inject write/publication failures and a process interruption.
UI tests use the real executor and reject worker access to session state.

These tests do not measure recognition quality or model language compliance.
Before tagging, perform the final local GUI/model smoke with the exact paired
revisions and configured model/runtime. Reuse copied historical transcripts
where possible; do not rewrite original regression evidence. Preserve the known
GTM-Hub human-reference whitespace. Record both candidate SHAs in release notes.

## Historical Lab fixture dependency

Four older experiment tests require six ignored files, absent from a fresh Git
worktree. Do not add them to the alpha source boundary or silently skip the tests:

- `artifacts/experiments/evidence_observations_v3/20260819_v3_single_run/h_resulting_action/parsed_observations.json`
- `artifacts/experiments/negative_act_form_v0/20260820_qwen35_9b_single_run/na-01/v3_style_input_observations.json`
- The same negative-act filename under `na-03`, `na-04`, `na-05`, and `na-06`.

For the alpha audit, these files were copied from the original Lab worktree to a
separate temporary test directory. That directory exposed the candidate's
`tests`, `prompts`, `samples`, `src`, and `scripts` as resource links. The full
suite ran there with the candidate Lab root on `PYTHONPATH` and the candidate's
absolute tests directory supplied to unittest discovery. All 413 tests passed.
The bare candidate worktree run instead reports four missing-fixture errors.
This is a historical test portability limitation, not a runtime dependency.

The paired Assistant suite passed all 107 tests with the candidate Lab backend;
no Whisper, diarization or Ollama inference was executed. These counts describe
the preparation validation and do not replace the final smoke-test record.
