+## Technical Debt & Issues
+### ~~[CRITICAL] No unit tests for ovoscope itself~~ ✅ FIXED
+62 unit tests across `test/unittests/test_capture_session.py`, `test/unittests/test_end2end.py`,
+`test/unittests/test_minicroft.py`, `test/unittests/test_pydantic_helpers.py`, and
+`test/unittests/test_audio_harness.py`.
+All pass (62 passed, 0 failed).
+---
+### ~~[MAJOR] Missing LICENSE file~~ ✅ FIXED
+LICENSE file (Apache-2.0) added to repo root. `pyproject.toml` correctly references it.
+---
+### ~~[MAJOR] `End2EndTest.execute()` returns `None`~~ ✅ FIXED
+`execute()` now returns `List[Message]`. Signature changed to
+`def execute(self, timeout: int = 30) -> List[Message]`. `assert_spoke()` builds on this.
+---
+### ~~[MAJOR] No type annotations on any public method~~ ✅ FIXED
+All public methods in `ovoscope/__init__.py` and new modules now have PEP 484 annotations.
+---
+### [MODERATE] `CaptureSession.capture()` returns `None` — captured messages inaccessible inline
+**Evidence**: `ovoscope/__init__.py` — `capture()` returns nothing. Captured
+messages are only accessible via `self.responses` after `finish()` is called. The pattern
+`capture.capture(msg); messages = capture.finish()` is functional but forces a two-step flow.
+**Impact**: Cannot chain captures or do inline assertions without accessing the attribute
+directly. Slightly awkward for advanced multi-turn test composition.
+**Recommended fix**: Return `List[Message]` (the current `self.responses` snapshot) from
+`capture()`, or add a `messages` property. No breaking change required.
+---
+### ~~[MODERATE] `get_minicroft()` busy-waits with no timeout~~ ✅ FIXED
+`get_minicroft()` now accepts `max_wait: float = 60` and raises `TimeoutError` if the deadline
+is exceeded. Signature: `def get_minicroft(skill_ids, *args, max_wait=60, **kwargs) -> MiniCroft`.
+---
+### ~~[MINOR] `setup.py` should migrate to `pyproject.toml`~~ ✅ FIXED
+`setup.py` removed. `pyproject.toml` uses `build-backend = "setuptools.build_meta"`,
+`dynamic = ["version"]`, and `[tool.setuptools.dynamic] version = {attr = "ovoscope.version.__version__"}`.
+`version.py` now exports `__version__`. Optional pydantic extras added:
+`pip install ovoscope[pydantic]`.
+---
+### [MINOR] CI action pins at `@master`
+**Evidence**: GitHub Actions workflows use `pypa/gh-action-pypi-publish@master` and
+`ad-m/github-push-action@master`. The `@master` ref is not pinned to a specific SHA, making
+builds non-reproducible if the upstream action changes.
+**Recommended fix**: Pin to `pypa/gh-action-pypi-publish@release/v1` and a specific SHA for
+`ad-m/github-push-action`.
+---
+## Next Steps (Priority Order)
+1. Address CaptureSession.capture() return value — usability
+2. Pin CI action refs — reproducibility

 # FAQ — `ovoscope`
+## How do I test AudioService or PlaybackService without real audio hardware?
+Use `AudioServiceHarness` or `PlaybackServiceHarness` from `ovoscope.audio`. Both run on a
+`FakeBus` with `MockAudioBackend`/`MockTTS` respectively — no real audio device, TTS engine,
+or network required. See [docs/audio-testing.md](docs/audio-testing.md) for the full API
+reference. Requires `pip install ovoscope[audio]` (or `ovos-audio` installed separately).
+
+## Why does AudioService.stop() silently ignore my stop() call in tests?
+`AudioService._stop()` — `ovos-audio/ovos_audio/audio.py` — has a 1-second stop guard:
+it does nothing if called within 1 second of `play()`. Tests must `time.sleep(1.1)` after
+`play()` before calling `stop()`.
+
+## Why doesn't FakeBus.wait_for_response() work in audio harness tests?
+`FakeBus.wait_for_response()` does not work for synchronous in-process handlers because the
+reply is emitted before the internal listener is registered. Use subscribe-emit-wait with a
+`threading.Event` instead. `AudioServiceHarness.get_track_info()` and `list_backends()`
+implement this pattern — `ovoscope/audio.py`.
+
 ## What is `ovoscope`?
 `ovoscope` is End-to-end test framework for OpenVoiceOS skills.
 ## How do I install it?
@@ -231,3 +248,22 @@ This was a bug where `async_messages` defaulted to `None` and was passed to `Cap
 Session context includes timestamps (e.g., `active_skills` activation time) that differ between recording and replay. Set `test_msg_context=False` on fixture tests. For skills with random dialog rendering (like quote pools), also set `test_msg_data=False`.
 ## Does `from_message()` filter GUI messages during recording?
 Yes — `from_message()` now accepts `ignore_gui=True` (default), which adds `GUI_IGNORED` messages to the capture filter. This prevents GUI namespace messages from appearing in recorded fixtures.
+## How do I override pipeline plugin config in a test (e.g. M2V model path)?
+Pass `pipeline_config` to `get_minicroft()`. It is a `dict` keyed by the plugin's config key under `Configuration()["intents"]`:
+```python
+croft = get_minicroft(
+    [SKILL_ID],
+    default_pipeline=M2V_PIPELINE,
+    pipeline_config={
+        "ovos_m2v_pipeline": {
+            "model": "Jarbas/ovos-model2vec-intents-distiluse-base-multilingual-cased-v2"
+        }
+    },
+)
+```
+The override is patched into `Configuration()["intents"]` before `super().__init__()`, so the pipeline plugin reads the test value in its `__init__`. It is restored in `stop()`. This is useful for forcing a specific model regardless of what `mycroft.conf` says locally.
+## Why do M2V tests skip when the multilingual model is not cached?
+`ovos-m2v-pipeline` classifies utterances using a pre-trained model whose `classes_` are fixed intent labels. A language-specific model (e.g. Portuguese-only) won't contain English intent names and will always return no match. The multilingual model (`Jarbas/ovos-model2vec-intents-distiluse-base-multilingual-cased-v2`) covers all OVOS skill intent names. Tests that use M2V should skip when this model is not cached locally (to avoid downloading a large model in CI). Download it once with:
+```bash
+python -c "from model2vec.inference import StaticModelPipeline; StaticModelPipeline.from_pretrained('Jarbas/ovos-model2vec-intents-distiluse-base-multilingual-cased-v2')"
+```

 # Maintenance Report — `ovoscope`
+## [2026-03-11] — Enhance Audio Testing Robustness and CI
+
+- **AI Model**: Claude Sonnet 4.6
+- **Actions Taken**:
+  - Added `LIGHT_TEST_PIPELINE` as a lightweight fallback when Adapt/Padatious are missing.
+  - Updated `MiniCroft` to auto-fallback to `LIGHT_TEST_PIPELINE` if stages are missing.
+  - Refactored `PlaybackServiceHarness` for better robustness (proper patch cleanup, timeout handling).
+  - Added skip guard to audio harness tests to prevent failures when `ovos-audio` is not installed.
+  - Fixed documentation path references and added prerequisites.
+  - Added missing `LICENSE` (Apache-2.0) file.
+  - Updated CI workflows to include `audio` extra for unit tests.
+- **Oversight**: All 147 unit tests pass locally.
+
+## [2026-03-10] — Add Audio Testing Harnesses
+
+- **AI Model**: Claude Sonnet 4.6
+- **Actions Taken**:
+  - Created `ovoscope/audio.py` — 5 new classes:
+    - `MockAudioBackend` (inherits `AudioBackend`) — no-op backend tracking state
+    - `AudioServiceHarness` — context manager wrapping `AudioService` with `MockAudioBackend`
+    - `MockTTS` (inherits `TTS`) — writes 44-byte silent WAV, records spoken utterances
+    - `PlaybackServiceHarness` — context manager wrapping `PlaybackService` with `MockTTS`
+    - `AudioCaptureSession` — records bus messages matching configurable prefix list
+  - Updated `ovoscope/__init__.py` — guarded import of audio harness classes
+  - Updated `pyproject.toml` — added `[audio]` optional dependency
+  - Created `test/unittests/test_audio_harness.py` — 38 unit tests (all passing)
+  - Created `ovos-audio/test/end2end/__init__.py` — empty marker
+  - Created `ovos-audio/test/end2end/test_audio_service_e2e.py` — 11 E2E tests (all passing)
+  - Created `ovos-audio/test/end2end/test_playback_service_e2e.py` — 7 E2E tests (all passing)
+  - Created `docs/audio-testing.md` — full API reference with source citations
+  - Updated `docs/index.md` — link to audio-testing.md
+  - Updated `FAQ.md` — 3 new Q&As for audio testing
+  - Updated `QUICK_FACTS.md` — new audio harness classes, updated test count
+- **Key design decisions**:
+  - `AudioServiceHarness` uses `autoload=False` then manually injects `MockAudioBackend`
+  - `PlaybackServiceHarness` patches `ovos_audio.playback.play_audio` to prevent real audio
+  - `TTS.queue` is class-level; harness drains it before each `PlaybackService` construction
+  - `stop()` MUST return `True` to trigger `mycroft.stop.handled` in `AudioService`
+  - `FakeBus.wait_for_response()` does not work in-process; subscribe-emit-wait pattern used
+- **Oversight**: All 38 ovoscope unit tests + 18 ovos-audio E2E tests pass
+
+## [2026-03-10] — Add `pipeline_config` parameter to `MiniCroft`
+- **AI Model**: Claude Sonnet 4.6
+- **Actions Taken**:
+  - Added `pipeline_config: Optional[Dict[str, Dict]] = None` parameter to `MiniCroft.__init__` — `ovoscope/__init__.py`
+  - Patches `Configuration()["intents"][plugin_key]` before `super().__init__()` so pipeline plugins read overridden config in their own `__init__`
+  - Restores all overrides in `MiniCroft.stop()` — `ovoscope/__init__.py`
+  - Updated `docs/minicroft.md`: added `pipeline_config` to constructor table and added "Pipeline Plugin Config Overrides" section with usage example
+  - Updated `FAQ.md`: added Q&A for `pipeline_config` and M2V multilingual model skip behaviour
+  - Added 5 unit tests in `test/unittests/test_minicroft.py::TestMiniCroftPipelineConfig`: patch active, restore after stop, existing key preserved, None is no-op, multiple keys
+- **Oversight**: 18/18 minicroft unit tests pass; confucius e2e suite: 20 passed, 2 skipped.
+- **Motivation**: Needed to force the M2V multilingual model in `TestConfuciusM2VEN` regardless of what `mycroft.conf` says locally. Language-specific models (e.g. Portuguese) don't contain English intent labels and always return no match.
+- **Oversight**: All ovoscope unit tests pass; confucius e2e suite: 20 passed, 2 skipped (M2V — multilingual model not cached locally).
