The unit suite validates production modules against hand-written stubs, so a
call site that no longer matches real Home Assistant stays green — that is how
D1, D2 and D3 reached master. This adds the check that would have caught them.
`tests/ha_api_drift.py` (stdlib-only, documented inline) parses every module of
custom_components/nvidia_shield and resolves each Home-Assistant dependency
against an INSTALLED homeassistant:
1. every `homeassistant.*` import — module present, attribute present (or a
submodule of that name exists, which is what `from package import submodule`
means) — catches D1/D2 and any future move;
2. every keyword argument passed to a known HA API (HA_CALL_OWNERS: the
ConfigFlow/ConfigEntries APIs we call) must exist in the real signature —
catches the `options_updates` class of bug;
3. every `self.<method>()` call in a class that inherits from an HA class is
compared with the real definition: a coroutine must be awaited and an
awaited call must be a coroutine — catches D3.
`tests/test_ha_api_drift.py` runs it against the production tree, asserts the
sweep is not vacuous (module/import/argument/await counters), and pins the red
proof with the four pre-fix forms, plus the green proof for the fixed forms. It
skips cleanly when homeassistant is absent, so the stdlib-only jobs are
unaffected.
`.gitea/workflows/test.yml` gains the `ha-api-drift` job — the one place Home
Assistant is installed — guarded by an explicit Python >= 3.13 check (Home
Assistant 2026.x requires it) and the same PEP 668 retry the test job uses.
Red proof against the real pre-fix revisions (svn-style checkout of
`git show HEAD:…` into a temp dir, and the pre-t35 config_flow.py for the kwarg):
media_player.py:965: broken-import: from homeassistant.components.media_player
import BrowseMediaSource: …BrowseMediaSource does not exist
diagnostics.py:93: broken-import: from homeassistant.util.diagnostic import
async_redact_data: module 'homeassistant.util.diagnostic' is not importable
config_flow.py:425: missing-await: self._async_handle_discovery_without_unique_id()
is a coroutine on homeassistant.config_entries.ConfigFlow
config_flow.py:700: unknown-kwarg: async_update_reload_and_abort() has no
'options_updates' parameter (exit 1 on that tree, exit 0 on this one)
Verified: variant 1 289 passed / 2 skipped; variant 2 (androidtvremote2) 290
passed / 1 skipped; ruff clean; `UV_PYTHON=3.13 uvx --with homeassistant --with
pytest-asyncio pytest tests/test_ha_api_drift.py -q` → 4 passed (the bare form of
that command needs the pin here only because this sandbox's default Python is
3.15 and pycares has no wheel for it / no CMake to build it; CI pins the
interpreter explicitly).
