v0.30.0

Added

• Quality Scale: Platinum. The three Platinum rules are now done — async-dependency, inject-websession, and strict-typing. pyproject.toml ships strict = true and CI's typing job blocks merges on any new mypy error. The cleanup pass took 392 → 0 strict errors (134 type-arg, 68 no-untyped-def, 59 no-any-return, 34 attr-defined, 32 no-untyped-call). All # type: ignore[no-any-return] are at REST/SQS JSON-payload boundaries — none in business logic.
• Native translations for the 5 Repairs issues added in v0.29.0 (onvif_init_failed, onvif_no_cameras, onvif_partial_cameras, sse_init_failed, sqs_init_failed): de / es / nl / sv / uk now match the FR quality. Placeholders ({error}, {connected}, {total}) preserved.
• Test suite: 146 → 313 tests (+114%). New entity tests use the object.__new__(EntityClass) pattern to exercise descriptor wiring and state mapping without a full HA fixture: alarm_control_panel SecurityState → AlarmControlPanelState routing for all 8 known states, binary_sensor / sensor / switch / valve / lock / select / number / device_tracker / button / event is_on / native_value / available / fire contracts. New module tests for api.py (URL routing per auth mode, devices cache TTL, rate-limit backoff), sse_manager (_find_device matching strategies, is_state_protected window, _handle_door_event mutations), _coordinator_arm (HA-action 10-second protection window, per-space lock identity), _coordinator_events (every SecurityState → bus event mapping). diagnostics.py coverage 42 → 87%.
• Performance invariants pinned (tests/test_perf_invariants.py): no f-string in _LOGGER.X(...) calls, every entity class declares __slots__, main update interval stays ≥ 30 s, debouncer cooldown stays in [0.1 s, 2 s]. Verified cold-start setup blocking at 1.5 s (< Platinum 2 s target).
• mypy CI job (.github/workflows/ci.yml) — runs on every push, fails the job on any new type error.

Fixed

• ONVIF Repairs issue reported 2/3 cameras connected when the user had 2 cameras + 1 NVR. The denominator counted the NVR, which AjaxOnvifManager.async_start deliberately skips (its sourceAliases-based channel→camera mapping is unreliable). The new target_count property excludes NVRs from the count so a healthy 2-camera + 1-NVR setup reports 2/2 and the repair issue auto-deletes instead of staying up as a phantom warning. target_count == 0 (NVR-only setup) now emits an info log rather than the misleading no_cameras issue.

Changed

• pyproject.toml [tool.mypy] flips to strict = true with implicit_reexport = true only for the homeassistant.* namespace (the HA team does not always update __all__ when public symbols move).
