Step 2 of 3 of the handler-lifecycle done-signal refactor: make ovos-workshop delegate its emission of the internal workshop->core done-signal trio to the new HandlerLifecycle util in ovos-bus-client (landed in OpenVoiceOS/ovos-bus-client#246).

What changed

In ovos_workshop/skills/ovos.py, the three event-wrapper callbacks emitted mycroft.skill.handler.{start,complete,error} by hand. The emission (only) is now delegated to ovos_bus_client.handler.HandlerLifecycle:

  • _on_event_start -> HandlerLifecycle(...).start()
  • _on_event_end -> HandlerLifecycle(...).complete()
  • _on_event_error -> HandlerLifecycle(...).error(error)

Zero behavior change

Byte-identical wire format, verified by a before/after equivalence check and by the new tests:

signal topic payload context
start mycroft.skill.handler.start {'name': <handler>} skill_id stamped, session preserved
complete mycroft.skill.handler.complete {'name': <handler>} same
error mycroft.skill.handler.error {'name': <handler>, 'exception': repr(error)} same

The util stamps context["skill_id"] on the forwarded copy (does not mutate the caller's message) and builds a fresh payload per emission (does not mutate the shared skill_data dict) — both strictly safer, with the emitted message unchanged.

Preserved (NOT part of the trio)

  • _on_event_end: still emits ovos.utterance.handled when is_intent, and still runs the settings.store() block.
  • _on_event_error: still speaks the skill.error dialog and logs the exception. The util deliberately does not speak; that UX stays in workshop.

Dep

Bumps the ovos-bus-client floor to >=2.6.0a1 (the published release that carries ovos_bus_client.handler; #246 landed after the 2.5.1a3 tag). Floor in pyproject, not CI.

Tests

Fills the previously-stubbed test_on_event_{start,end,error} in test/unittests/skills/test_base.py, asserting topic + payload + context["skill_id"]/session are unchanged, plus that empty handler_info disables emission and is_intent still emits ovos.utterance.handled. The existing test_decorators.py assertions on mycroft.skill.handler.start pass unchanged.

Note: full .[test] resolution currently hits an ecosystem conflict — published ovos-bus-client 2.6.0a1 requires ovos-spec-tools[langcodes]>=1.1.0a1, while ovos-core (a test dep) caps ovos-spec-tools<1.0.0. Tests were run with a spec-tools dependency override; ovos-core needs to lift its spec-tools cap for clean resolution. Not introduced by this PR.

…util

The three event-wrapper callbacks (_on_event_start/_on_event_end/
_on_event_error) emitted the internal workshop->core done-signal trio
(mycroft.skill.handler.{start,complete,error}) by hand. Delegate that
emission to the shared ovos_bus_client.handler.HandlerLifecycle util
(#246) so the wire format lives in one place.

Pure DRY: same topics, same payloads ({'name': <handler>} on
start/complete, + {'exception': repr(error)} on error), same
context['skill_id'] stamping and preserved session. The util stamps
skill_id on the forwarded copy rather than mutating the caller's
message, and builds a fresh payload per emission instead of mutating
the shared skill_data dict.

Preserved (NOT part of the trio): _on_event_end still emits
ovos.utterance.handled when is_intent and still runs settings.store();
_on_event_error still speaks the skill.error dialog and logs the
exception (the util deliberately does not speak).

Bumps the ovos-bus-client floor to >=2.6.0a1 (carries the util).
Fills the previously-stubbed test_on_event_{start,end,error} tests,
asserting the emitted topic/payload/context is unchanged.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

… guard

The rebase onto origin/dev reverted PR #440 (HandlerLifecycle util
delegation) and PR #442 (ovos.utterance.handled version guard) in
ovos.py, falling back to the pre-refactor manual emission that mutates
the caller's message.context. Restore both:

- _on_event_start/_end/_error delegate to HandlerLifecycle(...).{start,
  complete,error}() from ovos_bus_client.handler (PR #440). The util
  stamps skill_id on the forwarded copy rather than mutating the
  caller's message, so the original message.context is left untouched.
- _on_event_end guards the ovos.utterance.handled emission on
  _core_owns_utterance_handled() (PIPELINE-1 §9.5, PR #442): only emit
  for an older/absent ovos-core; with core >=2.3.0a1 the orchestrator
  owns it on the matched path.
- _on_event_error no longer mutates the shared skill_data dict; the
  util merges {exception: repr(error)} into the forwarded payload.

Tests:
- Restore the assertNotIn('skill_id', msg.context) assertion in
  test_on_event_start (valid again: the util does not mutate the
  original message context).
- Fix test_on_event_end_is_intent_still_emits_utterance_handled to
  patch _core_owns_utterance_handled=False so it is deterministic
  regardless of the installed ovos-core version (the test was failing
  on environments with ovos-core >=2.3.0a1 installed, including
  origin/dev).
- Add test_on_event_end_core_owns_suppresses_utterance_handled covering
  the >=2.3.0a1 branch (asserts the framework does NOT emit the
  end-marker when core owns it).

…xfails

The hard CI failure on this branch was the stale
test_on_event_end_is_intent_still_emits_utterance_handled: #442's
_core_owns_utterance_handled() guard suppresses workshop's
ovos.utterance.handled emission when ovos-core >= 2.3.0a1 (the orchestrator
owns the PIPELINE-1 §9.5 end-marker on the matched path), which CI now
installs. The #440 assertion is therefore stale.

- test_base.py: replace the stale single test with two deterministic
  branches (both monkeypatch _core_owns_utterance_handled):
    * _defers_utterance_handled_to_core — modern core (>=2.3.0a1); workshop
      must NOT emit ovos.utterance.handled.
    * _emits_utterance_handled_legacy — absent/old core; workshop still emits
      (migration-window back-compat).
- pyproject.toml: bump floors to the alphas carrying the singleton-registry
  SessionManager + §9.5 orchestrator ownership:
    ovos_bus_client >= 2.6.2a2, ovos-spec-tools >= 1.2.3a1,
    ovos-core >= 2.4.0a1 (test), ovos-adapt-parser >= 1.4.2a1 (test).

The two intent-layers e2e xfails added by this PR stay: under the spec's
'every session folds' model (OVOS-CONTEXT-1 §4 / OVOS-SESSION-1), the legacy
add_context/in-place context mutation is wiped by the next fold — the
genuine fix is to migrate IntentLayers to session.intent_context via
ovos.session.sync (§5.3), tracked separately.

* test: xfail intent-layers e2e tests broken on dev, unrelated to this PR

test_layers_advance_in_sequence_and_gate_intents and
test_inactive_layer_intents_do_not_match fail identically on a clean
origin/dev checkout with none of this PR's changes applied: the layer
context token is never applied (ovos_workshop/decorators/layers.py), so
gated intents never match. xfail them here to unblock this PR's CI; the
underlying layers bug needs its own fix in a separate PR.

* fix: harden utterance.handled test (§9.5), bump pins; keep layer-e2e xfails

The hard CI failure on this branch was the stale
test_on_event_end_is_intent_still_emits_utterance_handled: #442's
_core_owns_utterance_handled() guard suppresses workshop's
ovos.utterance.handled emission when ovos-core >= 2.3.0a1 (the orchestrator
owns the PIPELINE-1 §9.5 end-marker on the matched path), which CI now
installs. The #440 assertion is therefore stale.

- test_base.py: replace the stale single test with two deterministic
  branches (both monkeypatch _core_owns_utterance_handled):
    * _defers_utterance_handled_to_core — modern core (>=2.3.0a1); workshop
      must NOT emit ovos.utterance.handled.
    * _emits_utterance_handled_legacy — absent/old core; workshop still emits
      (migration-window back-compat).

  SessionManager + §9.5 orchestrator ownership:
    ovos_bus_client >= 2.6.2a2, ovos-spec-tools >= 1.2.3a1,
    ovos-core >= 2.4.0a1 (test), ovos-adapt-parser >= 1.4.2a1 (test).

The two intent-layers e2e xfails added by this PR stay: under the spec's
'every session folds' model (OVOS-CONTEXT-1 §4 / OVOS-SESSION-1), the legacy
add_context/in-place context mutation is wiped by the next fold — the
genuine fix is to migrate IntentLayers to session.intent_context via
ovos.session.sync (§5.3), tracked separately.

* fix: un-xfail intent-layers e2e (depends on ovos-utils#396), bump ovos-utils floor

The two intent-layers e2e tests xfailed in this PR are fixed upstream by
OpenVoiceOS/ovos-utils#396: FakeBus.emit was folding the message session
AFTER the bus handlers ran, using a pre-mutation emit-time snapshot, which
wholesale-replaced the SessionManager singleton (Session.update_from is
last-writer-wins) and wiped every in-place / synced session mutation the
handlers made — notably handle_add_context injecting the layer token into
sess.context. The #396 fix reorders FakeBus.emit to fold BEFORE handlers
(matching MessageBusClient.on_message receive -> fold -> handle order) and
drops the post-handler self-broadcast-back fold, so the legacy add_context
-> sess.context frame mechanism survives under folding again. No workshop
change is needed; the IntentLayers code is unchanged.

- test_intent_layers_e2e.py: revert the xfail markers added in 2aee2bd;
  both tests pass once ovos-utils >= 0.13.3a2 lands.
- pyproject.toml: bump ovos-utils floor to >= 0.13.3a2 (pending #396 release).
