Subject: [PATCH 03/60] feat: per-clip WakeWordProbe for benchmark/test
 harnesses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a self-contained probe that drives a real HotWordEngine over a single clip
the way the listening loop does: a few seconds of leading silence to warm the
engine's rolling feature window (openWakeWord et al. only emit once it is full,
~2.5 s — too little lead silently drops short positives and biases false
rejects), then the clip streamed frame by frame, returning a detection decision
plus latency and frames-to-detection. Unlike MiniVoiceLoop it needs no bus or
[listener] extra — just the [bench] extra (numpy). Tolerates the
HotWordEngine(lang) signature and the vestigial found_wake_word(frame) arg.

+"""Lightweight per-clip wake-word detection probe.
+
+Drives a **real** OVOS :class:`HotWordEngine` over a single audio clip the way
+the live listening loop does — a few seconds of leading silence to warm the
+engine's streaming feature buffers, then the clip streamed frame by frame —
+and returns a per-clip detection decision plus latency.
+
+Unlike :class:`ovoscope.voice_loop.MiniVoiceLoop` (which runs the full
+``DinkumVoiceLoop`` state machine and needs the ``[listener]`` extra), this is
+self-contained: no bus, no VAD, no state machine — just ``engine.update()`` /
+``engine.found_wake_word()`` over primed audio. Ideal for plugin test suites
+and benchmarks that score detection on labelled fixtures.
+
+Why the long lead matters
+-------------------------
+Streaming detectors (openWakeWord, microWakeWord, …) only emit a prediction
+once their rolling mel/embedding window is full (~2.5 s of frames). A clip fed
+with too little leading silence never fills that window: the activation is
+missed (a false reject), and on the shortest clips the half-full buffer raises
+a shape mismatch that drops the sample entirely. Priming with a few seconds of
+leading silence fills the window *before* the keyword arrives, exactly as a
+live microphone keeps the loop warm. :data:`PRIME_SECONDS` defaults to 3 s.
+
+Audio contract: mono ``float32`` in ``[-1, 1]`` at the engine's sample rate
+(16 kHz for every OVOS hotword engine). Resample upstream if your source
+differs. Needs the ``[bench]`` extra (numpy).

Subject: [PATCH 10/60] fix: always tear down MiniCroft and restore the
 process-wide session

End2EndTest.execute() and from_message() only stopped the MiniCroft on the
success path, so a failing assertion left SessionManager.bus,
default_session and Configuration patched for every later test. Both now
run stop() from a finally block.

MiniCroft snapshots the whole default Session at boot and restores it in
stop(), so inject_active activations and wire-folded session values no
longer outlive the test that made them.

Mock-TTS unduck timers are tracked, made daemon and cancelled in stop().
An orphaned timer could otherwise emit onto a closed bus and fold a stale
session onto the global SessionManager during a later test.

CaptureSession resets its eof state atomically, records a timed_out flag,
and returns a copy from finish(). A capture timeout now fails with a clear
message instead of surfacing as a message-count mismatch.

Subject: [PATCH 11/60] fix: report bus coverage as a per-test delta

BusCoverageTracker snapshotted the session-cumulative global collector and
added it into per-test counts, so every later test inherited the
invocations of every earlier one. The snapshot is now a baseline and the
report uses the delta over the tracker's own lifetime, frozen at
start_tracking() so the tracking window is not counted twice.

match() treated mycroft.skill.handler.start as a failure signal, but it
fires on a SUCCESSFUL match — so a successful match returned None. It also
checked the failure flag before the captured message and spun a watcher
thread that polled at 20Hz forever after a timeout.

match_result() now returns a discriminated matched/no-match/timeout
outcome and waits on the events directly. assert_no_match() fails on a
timeout instead of passing vacuously; match() keeps its old signature.

Subject: [PATCH 14/60] fix: emit the stimulus after subscribing in
 wait_for_match

The docstring told callers to emit after calling the helper, which is
impossible single-threaded because the helper blocks. It now takes an
optional emit= message and sends it once the handlers are in place.

A match that raced an intent failure could also be dropped; appends are
guarded by a lock and re-read once before giving up.

Subject: [PATCH 15/60] fix: make the OCP HTTP mock see the request URL

The side effect inspected `mock.url` on a MagicMock, so no configured URL
ever matched and json() always returned {}. It now lives on the patched
GET, which receives the URL.

OCPTest also waits for ovos.common_play.query.response instead of sleeping
half the timeout, and stops the MiniCroft from a finally block.

Subject: [PATCH 16/60] fix: release harness resources on exit

AudioServiceHarness.__exit__ skipped bus.close() when shutdown() raised.
ListenerHarness and MiniListener left their wildcard "message" capture
handler on the bus, so a shared bus kept feeding a dead harness.

PlaybackServiceHarness now restores the TTS.queue object it replaced and
refuses a second concurrent harness, because TTS.queue is process-wide
class state.

Subject: [PATCH 17/60] fix: raise on PHAL plugin load failure

A load failure was warned about and skipped, then resurfaced much later as
an unrelated assert_emitted timeout. Loading now raises by default; pass
tolerate_load_errors=True to keep going, in which case the errors are kept
in load_errors and quoted in assert_emitted failures.

MiniPHAL.__exit__ also detaches its capture handler and closes the bus.

Subject: [PATCH 18/60] fix: bound the shared MiniCroft lifetime in
 intent_cases

Cached MiniCrofts were never stopped and two could be live at once, each
clobbering the same globals. At most one stays live now, and an atexit
hook stops the rest.

_wait_for_m2v_sync removes its three listeners in a finally block and only
pays the 3.5s pad when no m2v activity was observed.

Subject: [PATCH 19/60] fix: replace a wedged simple-listener thread

feed_file ignored the join() result, so a listener thread that outlived
its stop() kept appending to _messages during the next run. A still-alive
thread is now logged and replaced with a fresh listener object.

+- `End2EndTest.execute()`, `End2EndTest.from_message()` and `OCPTest.execute()`
+  now stop their `MiniCroft` in a `finally` block. A failing assertion no
+  longer leaves the process-wide `SessionManager` and `Configuration` patched.
+- `MiniCroft` snapshots the whole default `Session` at boot and restores it in
+  `stop()`, so `inject_active` and wire-folded session values stay inside the
+  test that caused them.
+- Mock-TTS unduck timers are tracked, made daemon, and cancelled in `stop()`.
+  An orphaned timer can no longer emit onto a closed bus.
+- `BusCoverageTracker` reports the invocation DELTA over its own lifetime.
+  Earlier tests no longer inflate a later test's coverage.
+- `CaptureSession` resets its eof state atomically, records a `timed_out`
+  flag, and returns a copy from `finish()`. A capture timeout now fails with a
+  clear message instead of a message-count mismatch.
+- `ovoscope run` reuses the `MiniCroft` it booted instead of booting a second.
+- `PipelineHarness.match()` no longer treats `mycroft.skill.handler.start`
+  (a SUCCESS signal) as a failure, drops the spinning watcher thread, and gains
+  `match_result()`. `assert_no_match()` now fails on a timeout instead of
+  passing vacuously.
+- `wait_for_match()` accepts `emit=` so the stimulus is sent after
+  subscription, and no longer drops a match that races an intent failure.
+- The OCP HTTP mock attaches its side effect to the patched GET, so configured
+  URLs match. `OCPTest` waits for `ovos.common_play.query.response` instead of
+  sleeping half the timeout.
+- Harness `__exit__` methods close their bus and detach `"message"` capture
+  handlers even when shutdown raises (`AudioServiceHarness`, `MiniPHAL`,
+  `ListenerHarness`, `MiniListener`).
+- `PlaybackServiceHarness` restores the previous `TTS.queue` and refuses a
+  second concurrent harness.
+- Shared `MiniCroft` instances in `intent_cases` are stopped at exit, and at
+  most one stays live. The m2v sync wait removes its listeners and only pays
+  the 3.5s pad when nothing was observed.
+- `MiniSimpleListener.feed_file()` builds a fresh listener when the previous
+  thread refuses to die.
+- PHAL plugin load failures raise by default (`tolerate_load_errors=True` to
+  opt out); tolerated errors are quoted in `assert_emitted` failures.
+- `coverage.py` records manifest parse failures in the report instead of
+  silently understating coverage.
+- `RemoteRecorder.connect()` closes the client on a connect timeout so no
+  reconnect thread is left running.

Subject: [PATCH 23/60] test: split PHAL factory-failure test into strict and
 tolerated variants

raise-by-default made the old warn-and-skip expectation wrong; cover
both the default raise and the tolerate_load_errors opt-out.

Subject: [PATCH 24/60] fix: restore the default session by current object, add
 tomli for 3.10
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI showed two gaps: the session restore bailed out when boot replaced
the default-session singleton, leaking exactly the state it exists to
scrub — restore now targets whatever object holds the role at stop()
time. And on Python 3.10 there is no stdlib tomllib, so a malformed
pyproject.toml was silently ignored — depend on the tomli backport
there.

Subject: [PATCH 25/60] fix: snapshot/restore the default session on both
 bus-client APIs

ovos-bus-client 1.x has serialize/deserialize, 2.x to_dict/from_dict;
the snapshot silently became None on 1.x and the restore no-opped.
Support both and warn instead of failing silently.

-**Fixed — audit round 1 (test isolation, harness lifecycle, verdict accuracy):**
+[Full Changelog](https://github.com/OpenVoiceOS/ovoscope/compare/1.6.1a1...1.6.2a1)
 
-- `End2EndTest.execute()`, `End2EndTest.from_message()` and `OCPTest.execute()`
-  now stop their `MiniCroft` in a `finally` block. A failing assertion no
-  longer leaves the process-wide `SessionManager` and `Configuration` patched.
-- `MiniCroft` snapshots the whole default `Session` at boot and restores it in
-  `stop()`, so `inject_active` and wire-folded session values stay inside the
-  test that caused them.
-- Mock-TTS unduck timers are tracked, made daemon, and cancelled in `stop()`.
-  An orphaned timer can no longer emit onto a closed bus.
-- `BusCoverageTracker` reports the invocation DELTA over its own lifetime.
-  Earlier tests no longer inflate a later test's coverage.
-- `CaptureSession` resets its eof state atomically, records a `timed_out`
-  flag, and returns a copy from `finish()`. A capture timeout now fails with a
-  clear message instead of a message-count mismatch.
-- `ovoscope run` reuses the `MiniCroft` it booted instead of booting a second.
-- `PipelineHarness.match()` no longer treats `mycroft.skill.handler.start`
-  (a SUCCESS signal) as a failure, drops the spinning watcher thread, and gains
-  `match_result()`. `assert_no_match()` now fails on a timeout instead of
-  passing vacuously.
-- `wait_for_match()` accepts `emit=` so the stimulus is sent after
-  subscription, and no longer drops a match that races an intent failure.
-- The OCP HTTP mock attaches its side effect to the patched GET, so configured
-  URLs match. `OCPTest` waits for `ovos.common_play.query.response` instead of
-  sleeping half the timeout.
-- Harness `__exit__` methods close their bus and detach `"message"` capture
-  handlers even when shutdown raises (`AudioServiceHarness`, `MiniPHAL`,
-  `ListenerHarness`, `MiniListener`).
-- `PlaybackServiceHarness` restores the previous `TTS.queue` and refuses a
-  second concurrent harness.
-- Shared `MiniCroft` instances in `intent_cases` are stopped at exit, and at
-  most one stays live. The m2v sync wait removes its listeners and only pays
-  the 3.5s pad when nothing was observed.
-- `MiniSimpleListener.feed_file()` builds a fresh listener when the previous
-  thread refuses to die.
-- PHAL plugin load failures raise by default (`tolerate_load_errors=True` to
-  opt out); tolerated errors are quoted in `assert_emitted` failures.
-- `coverage.py` records manifest parse failures in the report instead of
-  silently understating coverage.
-- `RemoteRecorder.connect()` closes the client on a connect timeout so no
-  reconnect thread is left running.

Subject: [PATCH 28/60] fix: make ovoscope validate use
 pydantic_helpers.validate_fixture when available

cmd_validate always ran _basic_validate, contradicting docs/cli.md which
documented it as preferring pydantic_helpers.validate_fixture when the
pydantic extra is importable. Match the code to the documented behaviour
instead of weakening the docs, and add tests covering both the
pydantic-available and fallback paths.

Subject: [PATCH 29/60] docs: close the documentation audit gaps (Han audit
 round 1)

- cli.md: document the bus-coverage subcommand and the ovoscope-setup
  console script
- minicroft.md: add modernize/emit_legacy to the MiniCroft constructor
  table
- add docs/e2e-pipeline-harness.md (E2EPipelineHarness, bus helpers,
  intent-registration shims) and docs/intent-cases.md
  (IntentCase/register_intent_case_tests), linked from docs/index.md,
  README, and setup_skill.py's downloaded docs list
- add FAQ.md and CONTRIBUTING.md; repair the truncated AI Disclosure
  section in README (it referenced a changelog file that never shipped)
- index.md: scope the "does not load PHAL/audio" claim to
  MiniCroft/End2EndTest and point to the dedicated phal.md/audio-testing.md
  harnesses, which do cover them
- replace stale ovoscope/*.py:<line> citations across docs/*.md with
  symbol references so they can't drift out of sync with the source

Automated documentation audit provenance: gaps found by a Han
documentation audit (round 1) against current dev source.

Docs fixes by Claude (sonnet), orchestrated by Claude Fable.

+# FAQ
+
+Common questions and gotchas when using OvoScope.
+
+## Does OvoScope need a real OVOS install running?
+No. `MiniCroft` runs the skill manager and intent pipeline in-process on a
+`FakeBus` — there is no WebSocket server, no PulseAudio/audio stack, and no
+network access required for `record`/`run`/`diff`/`validate`. See
+[docs/index.md](docs/index.md) for what the in-process harness does and does
+not cover, and [docs/phal.md](docs/phal.md) / [docs/audio-testing.md](docs/audio-testing.md)
+for the separate PHAL and audio harnesses.
+
+## Why did my test fail with extra/missing messages I didn't expect?
+Only the keys you specify in `expected.data` and `expected.context` are
+checked — extra keys in the received message are ignored. If a message you
+didn't list is showing up as unexpected, check `ignore_messages` (see
+[docs/end2end-test.md](docs/end2end-test.md)) — some message types (e.g.
+`speak`, `ovos.skills.settings_changed`) are noisy or non-deterministic and
+are commonly filtered out.
+
+## My fixture recording is flaky / times out.
+Increase `--timeout` on `ovoscope record`, or the `timeout` kwarg on
+`End2EndTest.from_message`. If the skill under test depends on plugins that
+take time to warm up (e.g. `ovos-m2v-pipeline` syncing its label index),
+see `m2v_warmup` in [docs/intent-cases.md](docs/intent-cases.md) for how
+`ovoscope.intent_cases` handles that deterministically.
+
+## How do I test a skill that isn't installed as a plugin yet?
+Pass it via `extra_skills={"my-skill.test": MySkillClass}` to `MiniCroft` /
+`get_minicroft()` instead of `skill_ids`. See
+[docs/minicroft.md](docs/minicroft.md).
+
+## How do I test multiple languages?
+Pass `secondary_langs=[...]` to `get_minicroft()` so Adapt/Padatious
+register vocab for each locale. See "Multilingual Testing" in
+[docs/minicroft.md](docs/minicroft.md).
+
+## Where do I report a bug or ask something not covered here?
+Open an issue on [GitHub](https://github.com/TigreGotico/ovoscope/issues).

+# E2E Pipeline Harness
+`ovoscope.e2e` provides scaffolding for end-to-end tests of a single
+`ConfidenceMatcherPipeline` plugin (Adapt, Padatious, Padacioso, Nebulento,
+Palavreado, and similar engine families). Most such plugins need the same
+shape of test: patch the plugin's config, boot a `MiniCroft` pinned to that
+one pipeline, drive the bus with utterances, and assert on the dispatched
+intent message (or the `complete_intent_failure` fallback). `ovoscope.e2e`
+factors that shape out so a plugin only has to subclass
+`E2EPipelineHarness` and set a handful of class attributes.
+
+It also exposes standalone bus helpers and engine-family registration shims
+for callers that prefer pytest-style tests over `unittest.TestCase`.
+
+```python
+from ovoscope.e2e import E2EPipelineHarness
+```
+
+## Class: `E2EPipelineHarness` (`ovoscope/e2e.py`)
+
+Subclass of `unittest.TestCase`. Set these class attributes:
+
+| Attribute | Default | Description |
+|---|---|---|
+| `PIPELINE_ID` | `""` | OPM `opm.pipeline` entry-point name to pin `MiniCroft` to (e.g. `"ovos-nebulento-pipeline-plugin"`). `setUpClass` skips the test class if unset. |
+| `CONFIG_KEY` | `""` | Key under `Configuration()["intents"]` for the plugin's config. `setUpClass` skips the test class if unset. |
+| `PLUGIN_CONFIG` | `{}` | Dict merged into `Configuration()["intents"][CONFIG_KEY]` before `MiniCroft` starts. Restored on `tearDownClass`. |
+| `SKILL_ID` | `"test_skill_ovoscope"` | Skill id used by the helper methods when registering intents. Detached in `setUp` to keep tests isolated. |
+| `DEFAULT_LANG` | `"en-US"` | Language used by `make_utterance()` / `send_and_capture()` when no explicit `session` is given. |
+| `STARTUP_MAX_WAIT` | `60.0` | Seconds to wait for `MiniCroft` to reach `READY`. |
+| `MODERNIZE` | `True` | Forwarded to `MiniCroft`/`FakeBus` — legacy emit also dispatches its `ovos.*` spec counterpart. |
+| `EMIT_LEGACY` | `True` | Forwarded to `MiniCroft`/`FakeBus` — spec emit also dispatches the legacy topic. Set both `MODERNIZE` and `EMIT_LEGACY` to `False` to drive a single isolated namespace. |
+
+`setUpClass` boots one shared `MiniCroft` for the whole class (pinned to
+`[PIPELINE_ID]`) and stores the pipeline plugin instance on `cls.pipeline`.
+`tearDownClass` stops it and restores the original `Configuration()["intents"]`
+entry.
+
+### Instance attributes and helpers
+
+| Member | Description |
+|---|---|
+| `self.mc` | The running `MiniCroft` (class-scoped). |
+| `self.bus` | Shortcut for `self.mc.bus`. |
+| `self.pipeline` | The loaded pipeline plugin instance. |
+| `make_utterance(utterance, *, session=None)` | Build a `recognizer_loop:utterance` `Message` using `DEFAULT_LANG`. |
+| `send_and_capture(utterance, expected_types, *, timeout=5.0, session=None)` | Emit `utterance` and return the first message whose type is in `expected_types`, or `None` on `complete_intent_failure`/timeout. |
+| `expect_no_match(utterance, *, timeout=2.0, session=None)` | Assert emitting `utterance` produces `complete_intent_failure`. |
+
+```python
+from ovoscope.e2e import E2EPipelineHarness
+
+class TestNebulento(E2EPipelineHarness):
+    PIPELINE_ID = "ovos-nebulento-pipeline-plugin"
+    CONFIG_KEY = "ovos-nebulento-pipeline-plugin"
+
+    def test_match(self):
+        register_adapt_vocab(self.bus, "greeting", ["hello", "hi"])
+        msg = self.send_and_capture("hello", ["greeting_intent"])
+        assert msg is not None
+```
+
+---
+
+## Standalone bus helpers
+
+These work with any bus that implements `.on()` / `.remove()` / `.emit()`
+(`FakeBus` or `MessageBusClient`) and do not require `E2EPipelineHarness`.
+
+### `make_session(session_id="ovoscope-test", *, pipeline=None, blacklisted_intents=None, blacklisted_skills=None, lang="en-US") -> Session`
+Build a `Session` with the most common overrides preset.
+
+### `make_utterance_message(utterance, *, lang="en-US", session=None) -> Message`
+Build a `recognizer_loop:utterance` `Message`. If `session` is given, its
+serialized form is placed in the message context under `"session"`.
+
+### `wait_for_match(bus, expected_types, *, timeout=5.0, emit=None) -> Optional[Message]`
+Subscribe to `expected_types` and `complete_intent_failure`, then wait for
+the first match. Returns the matching `Message`, or `None` on failure or
+timeout.
+
+This helper **blocks**, so a single-threaded caller cannot emit the
+utterance and then call `wait_for_match` — the reply may arrive (and be
+missed) before the caller resumes. Pass the message to emit as `emit=`
+instead: `wait_for_match` subscribes its handlers first, then emits `emit`,
+so no reply can be missed.
+
+```python
+from ovoscope.e2e import wait_for_match, make_utterance_message
+
+msg = wait_for_match(
+    bus,
+    ["greeting_intent"],
+    timeout=5.0,
+    emit=make_utterance_message("hello"),
+)
+assert msg is not None
+```
+
+Only emit the message yourself beforehand (rather than via `emit=`) when
+the reply is guaranteed to be asynchronous relative to the emit call.
+
+### `wait_for_failure(bus, *, timeout=2.0) -> bool`
+Wait for a `complete_intent_failure` message; return whether one fired.
+
+---
+
+## Intent-registration shims
+
+Emit the bus event a given pipeline engine family expects, so tests can
+register intents/vocab without constructing the underlying plugin objects
+directly.
+
+| Function | Engine family | Emits |
+|---|---|---|
+| `register_padatious_intent(bus, name, samples, *, lang="en-US", settle=0.1)` | Padatious, Padacioso, Nebulento | `padatious:register_intent` |
+| `register_padatious_entity(bus, name, samples, *, lang="en-US", settle=0.1)` | Padatious, Padacioso, Nebulento | `padatious:register_entity` |
+| `register_adapt_vocab(bus, entity_type, words, *, lang="en-US", settle=0.1)` | Adapt, Palavreado | `register_vocab` (one per word) |
+| `register_adapt_intent(bus, builder, *, lang="en-US", settle=0.1)` | Adapt, Palavreado | `register_intent`. `builder` may be an `IntentBuilder` (`.build()`-ed automatically) or an already-built intent object. |
+| `detach_intent(bus, intent_name, *, settle=0.1)` | any | `detach_intent` |
+| `detach_skill(bus, skill_id, *, settle=0.1)` | any | `detach_skill` |
+
+Every shim sleeps `settle` seconds after emitting (default `0.1`) to give
+the pipeline plugin time to process the registration before the caller
+proceeds — pass `settle=0` to skip the wait when the caller does its own
+synchronization.

+# Intent Cases
+`ovoscope.intent_cases` lets skill authors describe expected intent routing
+as plain-text files instead of Python. Adding a phrase, an intent, or a
+whole new language is a pure text edit — no test code required.
+
+```python
+from ovoscope.intent_cases import register_intent_case_tests
+```
+
+## Layout
+
+```
+test/end2end/cases/
+    <lang>/
+        <IntentName>.intent.test     # one utterance per line, expected
+                                      # to match <IntentName>
+        no_match.test                # utterances expected to match
+                                      # NO intent of this skill
+```
+
+`#` comments and blank lines are ignored in `.test` files.
+
+## Usage
+
+One call, in a test module owned by the skill:
+
+```python
+# test/end2end/test_intents.py
+from pathlib import Path
+from ovoscope.intent_cases import register_intent_case_tests
+
+register_intent_case_tests(
+    globals(),
+    skill_id="ovos-skill-personal.openvoiceos",
+    handlers={
+        "WhoAreYou.intent": "PersonalSkill.handle_who_are_you_intent",
+        "WhatAreYou.intent": "PersonalSkill.handle_what_are_you_intent",
+    },
+    cases_dir=Path(__file__).parent / "cases",
+)
+```
+
+The call creates one `unittest.TestCase` class per pipeline family in the
+caller's module — `TestPadatious`, `TestPadacioso`, `TestM2V`, and
+`TestDefaultPipeline` by default — each containing one `test_*` method per
+`(lang, utterance)` pair found under `cases_dir`. A test passes if its
+pipeline family routes the utterance to the expected intent, matching
+realistic production cascade behaviour. Pass `pipelines={...}` to override
+the generated set with a subset, or with custom pipeline stage lists.
+
+---
+
+## `IntentCase` (`ovoscope/intent_cases.py`)
+Frozen dataclass: a single expectation — `utterance` in `lang` should match
+`intent`.
+
+| Field | Type | Description |
+|---|---|---|
+| `lang` | `str` | Language directory the case came from. |
+| `utterance` | `str` | The utterance text. |
+| `intent` | `Optional[str]` | Expected `"<IntentName>.intent"`, or `None` to assert the utterance falls through to `complete_intent_failure`. |
+| `source` | `Path` | The `.test` file the case was read from. |
+
+## `load_intent_cases(cases_dir, known_intents=None) -> List[IntentCase]`
+Discover every `IntentCase` under `cases_dir`. Returns `[]` if `cases_dir`
+does not exist. If `known_intents` is given, every `<Intent>.intent`
+filename found is validated against it — a typo raises `AssertionError`
+instead of being silently skipped.
+
+## `assert_intent_case(minicroft, skill_id, handlers, case, pipeline, *, ignore_messages=None, timeout=30) -> None`
+Fire `case.utterance` through `pipeline` on a running `minicroft` and assert
+routing, using `End2EndTest` under the hood.
+
+- `case.intent is None` — asserts the full `source_message` →
+  `complete_intent_failure` → `ovos.utterance.handled` sequence.
+- Otherwise — asserts `source_message` → `<skill_id>.activate` →
+  `<skill_id>:<intent>` → `mycroft.skill.handler.start` →
+  `mycroft.skill.handler.complete` → `ovos.utterance.handled`, using
+  `handlers[case.intent]` as the expected handler name. Raises
+  `AssertionError` up front if `case.intent` has no entry in `handlers`.
+
+`ignore_messages` defaults to `DEFAULT_IGNORE_MESSAGES` (`"speak"`,
+`"mycroft.audio.play_sound"`, `"ovos.common_play.stop.response"`) — message
+types that are noisy or non-deterministic and should not be asserted on.
+
+## `register_intent_case_tests(target_globals, *, skill_id, handlers, cases_dir, pipelines=None, ignore_messages=None, timeout=30, m2v_warmup=10.0) -> Dict[str, type]`
+Create per-pipeline `TestCase` classes in `target_globals` (pass `globals()`
+from the calling test module so pytest collects them).
+
+| Parameter | Default | Description |
+|---|---|---|
+| `target_globals` | required | `globals()` of the caller's test module. |
+| `skill_id` | required | Full skill plugin id, e.g. `"my-skill.author"`. |
+| `handlers` | required | `{"<IntentName>.intent": "<HandlerMethodName>"}`, covering every intent referenced by case files. |
+| `cases_dir` | required | Directory containing `<lang>/<Intent>.intent.test` and optional `<lang>/no_match.test` files. |
+| `pipelines` | `None` | `{class_suffix: pipeline_stage_list}` to override the default per-family classes (`DEFAULT_PIPELINE_FAMILIES`: Padatious, Padacioso, M2V, DefaultPipeline). |
+| `ignore_messages` | `None` | Extra message types to filter out of comparison, added to `DEFAULT_IGNORE_MESSAGES`. |
+| `timeout` | `30` | Per-case execution timeout, in seconds. |
+| `m2v_warmup` | `10.0` | Seconds to wait (upper bound) after booting `MiniCroft` for the m2v pipeline to finish syncing its label index. Set to `0` if not running M2V cases. |
+
+Returns `{}` with no classes created if `cases_dir` has no case files —
+this lets a freshly-copied template pass collection before any `.test`
+files are added.
+
+All generated test classes share one `MiniCroft` instance per
+`(skill_id, langs)` key, booted lazily on first use and cached at module
+scope. It is registered with `atexit` (`stop_shared_minicrofts()`) so it
+does not leak process-wide `SessionManager`/`Configuration` patches past
+the test run. At most one shared instance is kept alive at a time —
+requesting a different `(skill_id, langs)` key stops the cached instance
+first, since two live `MiniCroft`s fight over the same globals.
+
+## `autodiscover_from_conftest(conftest_dir, target_globals) -> Dict[str, type]`
+Zero-boilerplate alternative to calling `register_intent_case_tests`
+directly: looks for an `ovoscope_intent_cases` dict in the conftest
+namespace and calls `register_intent_case_tests` with it. A skill opts in
+by adding a `conftest.py` next to its `cases/` directory:
+
+```python
+ovoscope_intent_cases = dict(
+    skill_id="my-skill.author",
+    handlers={"DoX.intent": "MySkill.handle_do_x"},
+    # optional: cases_dir, pipelines, ignore_messages, timeout, m2v_warmup
+)
+```
+
+The ovoscope pytest plugin's `pytest_collect_directory` hook discovers this
+conftest, walks `<dir>/cases/`, and generates the same `TestCase` classes
+`register_intent_case_tests` would have created. Returns `{}` if the
+conftest has no `ovoscope_intent_cases` or the cases directory does not
+exist.

Subject: [PATCH 30/60] fix: layer pydantic validation on top of structural
 checks in cmd_validate

validate_fixture skips absent sections entirely, so replacing the basic
checks with it let a fixture with no expected_messages pass; and CI
(where pydantic is installed) rejected the legacy dict-shaped
source_message. Basic checks always run first, pydantic validates each
message on top, and a legacy dict section is treated as a one-message
list.

Subject: [PATCH 34/60] fix: SkillApi retention, capture arming, and exact GUI
 assertions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Memory (BLOCKER): SkillApi.bus is a process-wide class attribute that
SkillManager points at the harness FakeBus during boot. Left there after
stop(), it pinned the whole MiniCroft object graph — ~633MB per stopped
instance — so a suite that boots several harnesses kept all of them alive.
stop() now restores it and clears the handlers still on the harness bus.

Bus-coverage tracker: start_tracking() wraps bus.emit. An assertion failure
between start and stop left the wrapper installed for the rest of the process
and stacked one more wrapper per test. The tracked block is now in a
try/finally.

Session chaining: a response with no session in its context raised a bare
KeyError. It now says which source_message cannot be chained, and why.

CaptureSession: an end-of-test message emitted OUTSIDE a capture window
counted towards the next capture, which then returned at once with an empty
message list — a vacuous pass. A capture is now armed under the same lock
that resets the counter, and only an armed generation counts. __del__ is a
no-op when the MiniCroft has no bus.

Mock TTS: `if not self._stopped: bus.emit(...)` was a TOCTOU against stop().
Both sides now hold one lock, so the flag flip and the emit are exclusive.

Default session: the snapshot and the restore now use the SAME bus-client API
family (to_dict/from_dict or serialize/deserialize) — pairing them across
families rebuilt a wrong session. When the snapshot itself failed, the restore
no longer degrades to a total no-op: active_skills is put back explicitly.

GUI assertions: namespace and page comparisons used substring matching, so
they could not fail on a near match ("weather" passed on any namespace
containing it). They compare by equality now, with opt-in exact=False for the
old behaviour. assert_namespace_cleared also matches gui.clear.namespace, the
topic the GUI service really emits.

Subject: [PATCH 35/60] fix: evaluate the accuracy gate in pytest_sessionfinish
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The --ovoscope-accuracy-min gate set its failure flag in
pytest_terminal_summary and read it in pytest_sessionfinish. sessionfinish
runs FIRST, so the flag was always read before it was set and the gate could
never change the exit status — a CI job with 0% accuracy still exited 0.

The gate is now computed (and cached on the config) in sessionfinish;
terminal_summary only prints the cached result.

Subject: [PATCH 36/60] fix: stop false-green fixture diffs and stacked
 bus-emit wrappers

diff: a file without "expected_messages" fell back to an empty list, so two
unrelated JSON files compared []-vs-[] and the CLI reported "Identical" with
exit 0. It now raises ValueError, and the CLI turns that into a clean error.
_dict_diff uses a sentinel, so an expected None no longer matches an absent
key.

bus_coverage: stop_tracking() restores bus.emit only while it is still this
tracker's own wrapper, so it cannot clobber another tracker's wrapper.

Subject: [PATCH 37/60] fix: unwind harness state when __enter__ fails part-way

OCPPlayerHarness started eight mock.patches before constructing the real
player; PlaybackServiceHarness claimed TTS.queue and the _active singleton
before its patcher started; PipelineHarness booted a MiniCroft and then wired
the sink outside any guard. A failure in the middle left process-wide state
patched for the rest of the run.

Each __enter__ now unwinds through its own teardown before propagating.

PipelineHarness also clears the sink's stale verdict: an explicit intent
failure left the PREVIOUS match on _last_match, and match_result did not
reset it between utterances.

Subject: [PATCH 38/60] fix: resilience sweep across the listener, probe, and
 report helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- wakeword_probe: apply_hotword_compat() patched HotWordEngine.__init__ for
  the rest of the process. It is now a `hotword_compat()` context manager
  scoped to the engine construction it exists for.
- listener: `any(e.found_wake_word() ...)` short-circuits, and
  found_wake_word() is a destructive read — later engines stayed latched and
  reported a stale detection on the NEXT call. Every latch is read first.
- listener: the except ImportError around AudioTransformersService covered the
  constructor too, so a constructor bug surfaced as "install
  ovos-dinkum-listener". The guard now covers only the import.
- listener: a WAV that will not parse is logged before falling back to raw PCM.
- voice_loop: shutdown() detaches the bus capture handler, so a harness torn
  down without the context manager stops collecting messages.
- media_provider: real-provider calls run under a timeout (call_timeout,
  default 30s) instead of hanging the run on an unresponsive server.
- tts_intelligibility: a reference-STT failure is logged and marked
  (transcript=None plus transcribe_failed / transcribe_error in the report)
  instead of silently scoring wer=1.0 as if the TTS were unintelligible.
  Rendered file names use a sha1 prefix, not a randomised 32-bit hash.
- setup_skill: a failed SKILL.md download reports an error and exits 1 instead
  of leaving a half-installed skill and claiming success.

Subject: [PATCH 39/60] test: round-2 regression suite and stub-based
 CaptureSession tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds test_audit_round2.py — one adversarial test per audit finding, plus
direct coverage of helpers that had none: E2EPipelineHarness config restore
(including two subclasses back to back), wait_for_failure on timeout, the
adapt register/detach round trip, diff._dict_diff on nested dicts and lists of
dicts, the CLI on a missing and on a failing fixture,
_parse_setup_py_entry_points on good and malformed input, the PipelineHarness
match/failure sequence, and an anti-vacuity guard that an injected failure
really does propagate out of End2EndTest.

test_capture_session.py and TestCaptureSessionDel now drive a
SimpleNamespace(bus=FakeBus()) stub instead of booting a MiniCroft: the class
only touches minicroft.bus, and each boot retained hundreds of MB.

The GUI tests asserted namespaces that only CONTAINED the expected value —
exactly the false green being fixed — so they now assert the real namespace,
with new cases proving a near match fails.

 # Changelog
 
+## Unreleased
+
+**Han audit round 2 — fixes**
+
+- `MiniCroft.stop()` restores `SkillApi.bus` and drops the listeners on its own
+  bus. The class attribute pinned every stopped harness (~633MB each), so a
+  suite that boots several MiniCrofts kept all of them in memory.
+- The `--ovoscope-accuracy-min` gate is computed in `pytest_sessionfinish`,
+  which runs BEFORE `pytest_terminal_summary`. The gate now changes the exit
+  status; before, it could never fail a CI run.
+- The bus-coverage tracker is unwrapped in a `finally`, so a failing test no
+  longer leaves `bus.emit` wrapped for the rest of the process.
+- `OCPPlayerHarness`, `PlaybackServiceHarness` and `PipelineHarness` unwind
+  their process-wide patches when `__enter__` fails part-way.
+- `ovoscope diff` rejects a file with no `expected_messages` instead of
+  reporting two unrelated files as identical. An expected `None` now differs
+  from an absent key.
+- The GUI assertions (`assert_page_shown`, `assert_namespace_value`,
+  `assert_namespace_has_key`, `assert_namespace_cleared`) compare namespaces
+  and page names by equality. Pass `exact=False` for the old prefix behaviour.
+  `assert_namespace_cleared` also matches the `gui.clear.namespace` topic the
+  GUI service really emits.
+- The mock-TTS emit and `stop()` are mutually exclusive, so an unduck can no
+  longer land on a closed bus.
+- `CaptureSession` counts an end-of-test message only inside a capture window.
+- The default-session snapshot and restore use one bus-client API family, and
+  `active_skills` is restored even when the snapshot failed.
+- Resilience sweep: the hotword-compat patch is scoped to a context manager;
+  wake-word latches are all read before reducing; a reference-STT failure is
+  logged and marked (`transcribe_failed`) instead of scoring 1.0 silently; a
+  failed `SKILL.md` download exits 1; the dinkum-listener import guard covers
+  only the import; `MiniVoiceLoop.shutdown()` detaches the capture handler;
+  media-provider calls run under a timeout (default 30s).

Subject: [PATCH 40/60] test: build PipelineHarness through __init__ in the
 round-1 match test

The test bypassed __init__ with __new__ and set only the attributes
match_result used at the time, so it broke the moment match_result read one
more attribute. Constructing the object normally keeps it honest.

 # Changelog
 
-## Unreleased
-
-**Han audit round 2 — fixes**
-
-- `MiniCroft.stop()` restores `SkillApi.bus` and drops the listeners on its own
-  bus. The class attribute pinned every stopped harness (~633MB each), so a
-  suite that boots several MiniCrofts kept all of them in memory.
-- The `--ovoscope-accuracy-min` gate is computed in `pytest_sessionfinish`,
-  which runs BEFORE `pytest_terminal_summary`. The gate now changes the exit
-  status; before, it could never fail a CI run.
-- The bus-coverage tracker is unwrapped in a `finally`, so a failing test no
-  longer leaves `bus.emit` wrapped for the rest of the process.
-- `OCPPlayerHarness`, `PlaybackServiceHarness` and `PipelineHarness` unwind
-  their process-wide patches when `__enter__` fails part-way.
-- `ovoscope diff` rejects a file with no `expected_messages` instead of
-  reporting two unrelated files as identical. An expected `None` now differs
-  from an absent key.
-- The GUI assertions (`assert_page_shown`, `assert_namespace_value`,
-  `assert_namespace_has_key`, `assert_namespace_cleared`) compare namespaces
-  and page names by equality. Pass `exact=False` for the old prefix behaviour.
-  `assert_namespace_cleared` also matches the `gui.clear.namespace` topic the
-  GUI service really emits.
-- The mock-TTS emit and `stop()` are mutually exclusive, so an unduck can no
-  longer land on a closed bus.
-- `CaptureSession` counts an end-of-test message only inside a capture window.
-- The default-session snapshot and restore use one bus-client API family, and
-  `active_skills` is restored even when the snapshot failed.
-- Resilience sweep: the hotword-compat patch is scoped to a context manager;
-  wake-word latches are all read before reducing; a reference-STT failure is
-  logged and marked (`transcribe_failed`) instead of scoring 1.0 silently; a
-  failed `SKILL.md` download exits 1; the dinkum-listener import guard covers
-  only the import; `MiniVoiceLoop.shutdown()` detaches the capture handler;
-  media-provider calls run under a timeout (default 30s).

Subject: [PATCH 46/60] docs: gui-testing.md matches the exact-match assertion
 semantics

Round 2 switched the GUI assertions to exact matching with an opt-in
exact=False and added the gui.clear.namespace topic; this page still
taught the pre-fix substring behavior and omitted the parameter.

Found by the final adversarial verification (the only remaining
defect); fix by Claude Fable directly.

Subject: [PATCH 49/60] fix: MiniCroft boots against older ovos-core
 SkillManager (#128)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The latest ovoscope forwards enable_installer/enable_file_watcher/
enable_intent_service/enable_event_scheduler/enable_skill_api to
SkillManager unconditionally. Older ovos-core releases (the stable
release channel ships 1.3.x) predate some of these keyword arguments,
so super().__init__ raised TypeError and MiniCroft could not boot at
all — making the latest ovoscope unusable against an older core, which
is exactly what the conformance harness exercises against the pinned
stable/testing stacks.

Forward only the enable_* flags the installed SkillManager actually
accepts (via signature introspection; a **kwargs signature accepts
all). One ovoscope now boots on every supported core.

Adds a regression test simulating an old SkillManager signature.

Subject: [PATCH 52/60] fix: resolve unbounded get_response() hang on FakeBus
 (mechanism b, #138) (#130)

OVOSSkill.get_response()/ask_yesno() (ovos-workshop 7.0.6) spawn a killable
background thread that re-prompts forever when num_retries=-1 (the default)
and nothing ever answers it. On a real voice satellite the listener/GUI
eventually emits mycroft.skills.abort_question on user silence; ovoscope's
synchronous FakeBus never generates one, so any skill handler that calls
get_response()/ask_yesno() without a queued follow-up utterance hangs the
calling thread indefinitely (OVOSSkill._wait_response(),
ovos_workshop/skills/ovos.py ~1802-1809 - "while not ans: time.sleep(0.1)",
no deadline).

MiniCroft now arms a short watchdog timer on
"skill.converse.get_response.enable" that emits the existing
"mycroft.skills.abort_question" bus message (no new message type) if
".disable" hasn't fired first - mirroring what a real listener/GUI would
send on silence. This lets get_response()/ask_yesno() resolve to None
promptly instead of looping every get_response_timeout (20s default)
forever.

Watchdog timers are keyed by (skill_id, session_id) - the same two-part
scope ovos-workshop's own @killable_event("mycroft.skills.abort_question",
check_skill_id=True) already uses to decide which stalled thread an abort
is for. An adversarial review of an earlier version of this fix caught a
real regression here: a flat list of pending timers meant ANY skill's
".disable" cancelled EVERY other skill's still-pending watchdog too, so in
a fleet-style MiniCroft running multiple skills concurrently, one skill
finishing its (answered) get_response() would silently disarm a different
skill's watchdog - if that second question was never answered, it hung
forever again, defeating the fix for exactly the multi-skill case it needs
to hold up under. Scoping by (skill_id, session_id) and cancelling only the
matching entry on ".disable" fixes it; all remaining timers are still
cancelled in stop() the same way the existing mock-TTS timers already are.

The existing nested-speak_dialog(wait=True) mock-TTS handshake
(recognizer_loop:audio_output_start/end) already resolves correctly for
nested calls via its own per-call Timer; a regression test pins that
behavior alongside the get_response fix and its concurrency scoping.

Field evidence: OpenVoiceOS/ovos-skill-alerts#138 "Update 3" - py-spy
captures showing OVOSSkill._real_wait_response threads parked forever on
the ovoscope FakeBus, and PR #123's CI job silently hanging to the
30-minute kill on 4 of 5 Python versions after the last test finished.

+"""Regression tests for OpenVoiceOS/ovos-skill-alerts#138 (Update 3):
+
+ovoscope's synchronous FakeBus never completes the TTS handshake for
+NESTED speak calls, and never resolves an unanswered get_response()/
+ask_yesno() flow, so real skill handlers hang under the harness.
+
+Both tests must complete quickly (well under the 15-20s upstream ceilings)
+rather than hang.
+
+Also covers the follow-up defect found in adversarial review of ovoscope
+PR #130: the FIRST version of the get_response watchdog kept ONE flat list
+of pending timers, so ANY skill's `.disable` cancelled EVERY other skill's
+still-pending watchdog too. In a fleet-style MiniCroft running multiple
+skills concurrently, skill A finishing its (answered) get_response() would
+silently disarm skill B's watchdog, and if B's question was never answered
+it would hang forever again — exactly the bug this file exists to prevent.
+The fix scopes each watchdog by (skill_id, session_id), the same two-part
+scope `ovos_workshop`'s own
+`@killable_event("mycroft.skills.abort_question", check_skill_id=True)`

Subject: [PATCH 55/60] fix: drain pyee listeners before teardown to avoid
 reentrant-__del__ deadlock (#132)

pyee's EventEmitter.remove_all_listeners() holds its internal, non-reentrant
lock while dropping self._events. If freeing the emitter's last reference to
a bound-method listener triggers the owner's __del__, and that __del__ calls
bus.remove()/remove_listener(), it re-enters the same lock from the same
thread and deadlocks permanently -- observed as 30-minute CI hangs in
skill-repo ovoscope teardowns.

MiniCroft.stop() now pops every key out of bus.ee._events itself, outside
pyee's lock, and runs gc.collect() before anything that can trigger
remove_all_listeners(), so any reentrant __del__ runs while the lock is
free. Same workaround as the minicroft fixture in
ovos-skill-application-launcher's test/end2end/test_intents_en_us.py
(merged PR #108, dev).

Added test/unittests/test_teardown_deadlock.py: a direct pyee-level test
proves the mechanism deadlocks without the drain and is fixed with it, and
a MiniCroft.stop() smoke guard reproduces the real hang against unpatched
code under full-suite state (though not reliably in isolation, since this
dependency stack's FakeBus.close() doesn't call remove_all_listeners() on
its own).

+"""Regression test for a pyee re-entrant-lock deadlock during bus teardown.
+
+pyee's ``EventEmitter.remove_all_listeners()`` holds its internal,
+non-reentrant ``threading.Lock`` while replacing ``self._events`` (or
+``self._events[event]``). If dropping the emitter's reference to a
+bound-method listener frees the *last* reference to that listener's owner,
+the owner's ``__del__`` runs synchronously, inside the locked block. If that
+``__del__`` calls ``bus.remove()`` / ``bus.ee.remove_listener()``, it tries
+to re-acquire the same lock from the same thread -> permanent deadlock
+(observed as 30-minute CI hangs in skill-repo ovoscope teardowns; see
+https://github.com/OpenVoiceOS/ovoscope for the reported symptom and
+ovos-skill-application-launcher's ``test/end2end/test_intents_en_us.py``
+minicroft fixture, merged PR #108 on dev, for the proven workaround this
+mirrors).
+
+The fix (``MiniCroft.stop()`` in ``ovoscope/__init__.py``) drains
+``bus.ee._events`` and runs ``gc.collect()`` *before* anything that can
+trigger ``remove_all_listeners()``, so any reentrant ``__del__`` fires while
+the pyee lock is free.
+
+Reproduction note
+------------------
+The dependency versions pinned for this repo route ``MiniCroft.stop()``
+through ``FakeBus.close()``, whose ``on_close()`` is a no-op — it never
+calls pyee's ``remove_all_listeners()`` directly, so in isolation
+``test_minicroft_stop_completes_quickly`` passes even against unpatched
+``ovoscope/__init__.py``. Under the *full* test-suite run, though, shared
+process state (accumulated listeners/threads from earlier tests) is enough
+to reproduce the real deadlock end-to-end: on unmodified
+``ovoscope/__init__.py``, running the full ``test/unittests`` suite makes
+``test_minicroft_stop_completes_quickly`` fail/hang; with the fix applied,
+the full suite passes. So ``test_pyee_reentrant_del_deadlocks_without_drain``
+exercises the underlying pyee mechanism directly and deterministically
+(proving (a) it deadlocks with no drain and (b) the exact drain sequence
+used in ``MiniCroft.stop()`` prevents it), while
+``test_minicroft_stop_completes_quickly`` is the smoke guard on the real
+call path — deterministic only in full-suite context, so treat it as best
+-effort in isolation but load-bearing in CI.

Subject: [PATCH 58/60] fix: accept canonical spec topics in captured-stream
 assertions (#136)

Producers emit canonical `ovos.*` spec topics since workshop#425, but
ovoscope's execute() captures via the bus catch-all, so a pre-spec
producer vintage on the wire can still deliver the legacy name instead.
Filters that hard-coded the legacy spelling against that captured
stream broke on canonical-only producers.
