What does this PR do?

Adds the narrow Home Assistant Core schema-converter compatibility bridge extracted from #2056.

Home Assistant 2026.8 provides voluptuous_openapi.convert_to_voluptuous, while 2026.9 replaces that dependency with probatio.from_openapi. The component now:

  • prefers the existing voluptuous_openapi converter, leaving current 2026.8 behavior unchanged;
  • falls back to probatio.from_openapi only when the top-level legacy module is absent;
  • resolves and caches the converter during the existing executor probe, so tool-schema conversion performs no imports on Home Assistant's event loop; and
  • preserves nested ModuleNotFoundError failures instead of misclassifying them as a version transition.

This also addresses Patch76's concern 3 on #2056. No localization changes are included.

📝 Walkthrough

Walkthrough

The LLM API now lazily selects the schema converter from voluptuous_openapi or probatio. SDK probing validates converter availability and caches the result. Tests cover fallback behavior, nested import errors, and threaded initialization.

Changes

Schema converter compatibility

Layer / File(s) Summary
Lazy schema converter resolution
custom_components/ha_mcp_tools/llm_api.py
The API adds a cached converter lookup that prefers voluptuous_openapi and falls back to probatio. Parameter conversion uses the typed wrapper.
Probe integration and compatibility tests
custom_components/ha_mcp_tools/llm_api.py, tests/src/unit/_embedded_stubs.py, tests/src/unit/test_llm_api.py
SDK probing validates schema converter availability. Test stubs include probatio. Tests cover converter selection, fallback behavior, nested import errors, caching, and off-event-loop probing.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 43944

This localized compatibility fix preserves the existing converter path and adds support for the newer dependency without changing public interfaces or deployment behavior. No actionable merge-blocking risk remains beyond normal checks and review.

288-303: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a test for preserved nested ModuleNotFoundError.

test_falls_back_to_probatio_on_newer_core only covers the case where err.name == "voluptuous_openapi". The PR objectives call out that nested ModuleNotFoundError failures (a different err.name, e.g. a missing dependency of voluptuous_openapi itself) must propagate instead of triggering the Probatio fallback. Add a case where importlib.import_module("voluptuous_openapi") raises ModuleNotFoundError with a different name, and assert that convert_to_voluptuous re-raises it rather than falling back to probatio.

✅ Proposed additional test
     def test_falls_back_to_probatio_on_newer_core(self, monkeypatch):
         schema = {"type": "object"}
         probatio = SimpleNamespace(from_openapi=lambda value: {"probatio": value})

         def _import_module(name):
             if name == "voluptuous_openapi":
                 raise ModuleNotFoundError(
                     "No module named 'voluptuous_openapi'",
                     name="voluptuous_openapi",
                 )
             assert name == "probatio"
             return probatio

         monkeypatch.setattr(llm_api.importlib, "import_module", _import_module)

Implementation Summary

  • Kept Home Assistant 2026.8 behavior unchanged by preferring voluptuous_openapi.convert_to_voluptuous, with probatio.from_openapi used only when the legacy top-level module is absent.
  • Addressed Patch76 concern 3 from feat: add Klingon localization #2056 by caching the resolved converter and warming it during the existing executor dependency probe, preventing repeated failed imports on the event loop.
  • Preserved nested ModuleNotFoundError failures and added regression coverage for legacy selection, Probatio fallback, nested import failures, and one-time off-loop initialization.
  • Kept the PR scoped to the Probatio compatibility shim; no localization changes from feat: add Klingon localization #2056 are included.
  • All CI checks pass on 43944c65, including Mypy, Ruff, unit tests, component E2E, and stable/beta HAOS embedded and in-addon lanes.
