 The suite now has 42 passing offline tests. Compilation with the temporary cache
 and `git diff --check` pass. The API basis is HA's

+## Follow-up: HA Core harness and CI
+
+Added a separate `tests/ha` pytest suite using the real Home Assistant 2025.12.0
+package and matching fixtures, pinned for Python 3.13. All 14 tests pass locally,
+alongside the existing 42 offline tests. The full `scripts/check.sh` checks and
+`pip check` passed. The suite exercises the actual config manager, config/options
+schemas, registry, scheduler and Store API, with mocked disk I/O and simulated
+sensor/reference entities. A service-call guard covers every test. No actuator
+calls were observed. Tests include cold setup with stored data/manual off, but not
+a full HA process restart or HAOS hardware validation.
+
+Added a Forgejo/Gitea Actions workflow and lightweight package/translation checks.
+Remote runner execution, a modern-HA version matrix, dedicated lint/type checks,
+full process restart, partial platform failure and real disk-failure testing remain
+open. The test harness needed a pycares 4.11.0 pin for compatibility with HA's DNS
+dependency. Integration runtime dependencies and behavior are unchanged.
