Judge 1: TEST COVERAGE ANALYST

[HIGH] MQTT plugin state.py (1273 lines) is well tested with dedicated test_mqtt_state.py. However, no specific tests for memory leaks or high-throughput scenarios.
[HIGH] Critical dependency gap: pyproject.toml lists MQTT, automation, and alerting plugins in entry points but does not list paho-mqtt, aiomqtt, or other plugin dependencies. This will cause ImportError at runtime.
[MEDIUM] Automation plugin has dedicated test files with condition evaluation and action execution tests. No tests for concurrent rule evaluation or race conditions.
[MEDIUM] Alerting plugin tests cover all three channels including failure modes. No tests for cooldown/throttling logic under rapid triggers.
[LOW] SSE endpoint has maxsize=64 queue per client and drops oldest on backpressure. Tests exist but no stress tests for 20 concurrent clients.

[HIGH] MQTT graceful degradation gap: if aiomqtt import fails, connect() catches ImportError, but no test verifies the plugin remains dormant. The ImportError scenario is untested.
[HIGH] WebSocket command handler (_handle_ws_command) has no validation of incoming JSON structure. Malformed commands are silently dropped. Client receives no error feedback.
[MEDIUM] MQTT state.py colour parsing handles invalid JSON but returns None without error logging. Invalid colours increment error_count silently.
[MEDIUM] Concurrent config updates via MQTT: two simultaneous fan duty commands call config_manager.update() without locking. Race conditions possible.
[MEDIUM] Fan curve validation: state.py accepts custom curves without checking temperature ordering. Out-of-order curves could cause undefined fan behaviour.
[LOW] CLI _api_* helpers catch HTTPStatusError and ConnectError but don’t handle timeouts. 10-second timeout produces uncaught RequestError.

[HIGH] System monitor polling at 2.0 seconds spawns collection every cycle. At 20 SSE clients, this is 40 allocations/sec. No memory profiling evidence.
[MEDIUM] MQTT state caches (_last_fan_state, etc.) are never cleared or size-limited. Stable in practice but payload size is unbounded.
[MEDIUM] SSE EventBridge creates 13 async handlers calling json.dumps() per event. No batching. Queue buildup possible at high event rates.
[MEDIUM] WebSocket command handler has no rate limiting per connection. A client can flood with 1000 commands/sec.
[MEDIUM] MQTT topic handlers may fire concurrently on reconnect when broker sends retained messages. No mutex protection.
[LOW] Automation engine _resolve_field() recursively traverses nested dicts with no depth limit. Stack overflow unlikely but possible.

[HIGH] MQTT plugin fails gracefully when disabled. But if aiomqtt is not installed and MQTT is enabled, plugin.start() catches ImportError leaving self._mqtt = None. Subsequent route handlers will crash with AttributeError.
[HIGH] Web dashboard has nice graceful degradation for unavailable plugins: all _fetch_*_data() functions catch exceptions and return defaults.
[MEDIUM] Automation plugin: if config is invalid, plugin.start() succeeds silently. No event emitted, no API status change.
[MEDIUM] Alerting plugin initialises AlertDispatcher even if all channels are disabled. Alert actions succeed but send nowhere silently.
[LOW] System monitor catches exceptions on case temperature reads and continues. If all hardware fails, degraded flag is set correctly.
[LOW] EventBus listeners swallow exceptions without propagating. Good defensive programming.

Missing plugin dependencies in pyproject.toml – MQTT/automation/alerting deps not declared. RuntimeImportError for users.
WebSocket command validation missing – malformed commands silently dropped, no feedback.
MQTT graceful degradation incomplete – route handlers crash if aiomqtt missing but enabled.
Concurrent MQTT command race condition – no synchronisation on config updates.
Version mismatch: pyproject.toml still says 0.1.0.

Excellent graceful degradation in web dashboard – all fetch functions catch and return defaults
Robust MQTT error handling – colour/JSON parsing catches exceptions, error counters for visibility
Test coverage substantial – 1193 tests (up from 194), 54% to 68% coverage
Defensive event bus listeners – prevent cascading failures
SSE backpressure handling – drops oldest message rather than blocking
Automation rule engine well designed – condition evaluation with field path resolution, operator dispatch
