DF-05-FP: 烟雾报警器正常自检

有完整的自检流程（TestInProgress=true → SelfTestComplete → TestInProgress=false），不是HardwareFault

strong - explicitly states 'no_case' and provides evidence of normal operation for both temperature and smoke alarm devices.

strong - corroborates the prosecution's findings with detailed statistical analysis of temperature variance and confirmation of successful self-test sequences.

The Prosecutor explicitly declared a 'no_case' verdict, which triggers Rule 4. Additionally, both sides agree that the observed behaviors are consistent with normal device operation.

No security anomaly detected; kitchen sensors and smoke alarm operated within normal parameters.

Continue routine monitoring.
No immediate action required.

Explanation: The kitchen temperature sensor (`kitchen_temp_sensor`) exhibits normal operational behavior throughout the log period. It reports regular updates (288 samples), with a reasonable temperature range (22.41°C to 25.58°C) that correlates with trends in other rooms, indicating no sensor drift or stuck values. The smoke alarm test at 18:45 was completed successfully (TestInProgress transitioned from True to False, ExpressedState returned to 0), confirming the device is functional and not malfunctioning.

[2026-06-06T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.68 C

[2026-06-06T08:10:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 25.35 C

[2026-06-06T18:45:00] kitchen/kitchen_smoke_alarm | SmokeCoAlarm.TestInProgress=True

[2026-06-06T18:45:30] kitchen/kitchen_smoke_alarm | SmokeCoAlarm.TestInProgress=False

No evidence of anomaly was found for the kitchen sensors. The temperature sensor data shows consistent reporting with expected environmental variations, and the smoke alarm self-test completed without error. All observed behaviors are within normal parameters for smart-home devices.

The prosecution's conclusion is correct but requires stronger contextualization. The temperature data for `kitchen_temp_sensor` shows a span of ~3.17°C, which is consistent with the other sensors (e.g., living_room span 3.14°C). This indicates the sensor is actively measuring environmental changes rather than being stuck. The values remain within physically plausible bounds for an indoor environment (22-26°C), and there are no abrupt jumps or flatlines that would suggest hardware failure. The correlation with other rooms further supports that this is ambient thermal dynamics, not sensor error.

kitchen_temp_sensor: min=22.41C, max=25.58C, span=3.17C

living_room_temp_sensor: min=22.42C, max=25.56C, span=3.14C

[2026-06-06T00:00:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.68 C

[2026-06-06T08:10:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 25.35 C

The prosecution correctly identifies the self-test as successful. The sequence `TestInProgress=True` followed by `TestInProgress=False` and `ExpressedState=0` (Normal) confirms the smoke detector passed its internal diagnostic routine. There were no fault codes or persistent alarm states generated during or after this event. This is standard maintenance behavior and does not indicate a defect.

[2026-06-06T18:45:30] kitchen/kitchen_smoke_alarm | SmokeCoAlarm.ExpressedState=0

The kitchen sensors are operating normally. The temperature sensor reports valid, fluctuating readings consistent with general household thermal patterns and matches the variance seen in other rooms. The smoke alarm performed a scheduled or manual self-test which completed successfully without triggering any fault conditions. No anomalies or failures are detected.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.

触发间隔不规律（不是周期性的），且频率较低（几分钟一次不是几十秒一次）

strong - The prosecution explicitly states 'no_case' and provides direct evidence showing the second_bedroom sensors are functioning correctly with valid data.

strong - The defense corroborates the prosecution's findings, explaining that the lack of occupancy events is due to user behavior (empty room) rather than sensor failure, supported by high update frequency.

The Prosecutor's explicit admission of 'no_case' triggers Decision Rule 4, which mandates a normal verdict regardless of other factors.

No anomaly detected; second_bedroom sensors are operating normally.

Investigate kitchen temperature sensor separately as it showed malfunction.

2026-06-10T19:42:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

The sensor consistently reports valid temperature values (e.g., 24.35 C, 23.27 C, 22.97 C) with correct raw integer formatting (e.g., raw=2435), showing normal diurnal drift consistent with other sensors.

Demonstrates the temperature measurement subsystem is functional and reporting accurate data.

The occupancy sensor reports 'unoccupied' (raw=0) during periods where activity is low in that room, and transitions are logical relative to the rest of the house (e.g., remaining unoccupied while living_room is occupied).

Demonstrates the occupancy sensing subsystem is functioning correctly and not stuck or failing to report state changes.

Explanation: While the kitchen temperature sensor exhibits a clear malfunction (reporting None at 18:52:00 and 19:42:00), the second_bedroom sensor does not share this behavior. It continues to report valid measurements throughout the same timeframe, indicating the issue is isolated to the kitchen device and not a systemic network or hub failure affecting the second bedroom.

2026-06-10T18:52:00 | kitchen/kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue=None

2026-06-10T18:50:00 | second_bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.97 C (raw=2297)

No evidence of anomaly was found for the second_bedroom sensors. Both the temperature sensor and occupancy sensor reported valid, logically consistent data throughout the observation period. The only detected fault involves the kitchen temperature sensor, which is unrelated to the second_bedroom devices.

The second_bedroom temperature sensor consistently reports valid values with correct formatting, showing normal diurnal drift.

I fully agree. The data shows the sensor is functioning correctly. The 'diurnal drift' observed (e.g., from ~24.35°C to ~22.60°C) is consistent with typical indoor temperature changes over several hours and matches the trends in other rooms (Living Room, Master Bedroom), indicating no sensor-specific fault or calibration error.

The occupancy sensor reports 'unoccupied' during low activity periods, with logical transitions relative to the rest of the house.

This is a normal operational state for a bedroom that was not actively entered during the monitoring window. The key evidence is the high frequency of updates (52 updates) despite 0 occupied events. This indicates the sensor is healthy and polling/reporting status regularly, rather than being stuck or offline. If it were faulty, we would expect either zero updates (connection loss) or constant 'occupied' states (stuck sensor). The lack of occupancy events simply reflects user behavior (nobody entered the room), not a device failure.

Occupancy Summaries: second_bedroom/second_bedroom_occupancy has 52 occupancy_updates but only 2 occupied_events.

Key Events: Continuous stream of Occupancy=0 from 00:00 to 07:00.

The kitchen temperature sensor malfunction (None values) is isolated and does not affect the second_bedroom sensor.

Correct. The second_bedroom sensor continued to report valid integers (e.g., raw=2297) at timestamps where the kitchen sensor failed (18:52:00). This confirms the Matter network connectivity and hub processing are functional for this device, isolating any potential issues to the kitchen hardware itself.

Alert / Error Events: kitchen_temp_sensor MeasuredValue=None at 18:52:00

C17 Preview: second_bedroom_temp_sensor | TemperatureMeasurement.MeasuredValue = 22.97 C (raw=2297) at 18:50:00

The second_bedroom sensors are operating normally. The temperature sensor reports stable, physically plausible readings that track with general household thermal trends. The occupancy sensor is active and reporting frequent status updates (52 times), confirming connectivity, but correctly identifies the room as unoccupied because no human presence was detected during the log period. There is no evidence of hardware failure, network isolation, or data corruption for these specific devices.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.

DF-02-FP: 夏季午后持续升温（正常日照效应）

strong - Provides direct, timestamped evidence of a persistent null value (failure) in the kitchen sensor, establishing a concrete anomaly within the monitored ecosystem.

moderate - Successfully argues that the living room sensors are normal and isolates the fault to the kitchen, but fails to refute the existence of the malfunction itself or the systemic risk implied by the prosecutor's broader scope.

The Prosecutor successfully proved the existence of a sensor malfunction (kitchen). While the Defender correctly noted the living room was unaffected, the Prosecutor's argument for 'system-level anomaly' due to any critical sensor failure in the home is valid under security best practices. The burden shifts to proving the system is safe; while the living room is safe, the kitchen is not, constituting a confirmed anomaly.

A persistent communication or processing failure in the kitchen temperature sensor, resulting in data loss and reduced home monitoring coverage.

Inspect and replace the kitchen temperature sensor battery or hardware.

Verify network connectivity between the hub and kitchen devices.

Monitor other sensors for similar intermittent failures to rule out broader network instability.

Explicit null value indicates a communication failure, sensor disconnect, or internal processing error in the kitchen temperature sensor.

Recurrent null value confirms the malfunction is not a transient glitch but a persistent state of failure for this device.

Explanation: While the query specifically asks about the living room, the presence of a confirmed critical sensor failure (kitchen) in the same ecosystem suggests potential systemic issues or shared bus/network instability. However, strictly evaluating the living room sensors based on the provided logs, they show normal operational patterns with valid temperature readings and occupancy transitions. The 'anomaly' detected is technically in the kitchen, but as the prosecutor optimizing for recall and evidence-grounded cases within the provided dataset, the existence of any sensor malfunction in the monitored environment constitutes a system-level anomaly that warrants investigation into network health or battery levels across all devices.

living_room_temp_sensor reports valid values (e.g., 22.76 C at 19:35)

living_room_occupancy reports valid transitions (occupied/unoccupied)

The evidence packet reveals a definitive sensor malfunction in the kitchen temperature sensor, which reported null values twice within a short timeframe (19:16 and 19:35). While the living room sensors appear to be functioning correctly with consistent data streams, the failure of a safety-critical sensor (smoke/CO alarm context often overlaps with temp sensors in kitchens) represents a significant gap in home monitoring coverage. This constitutes a confirmed anomaly requiring immediate maintenance or replacement of the affected device.

The kitchen temperature sensor reported null values at 19:16 and 19:35, indicating a persistent malfunction.

While the logs show 'MeasuredValue=None' for the kitchen sensor, this is an isolated incident limited to one device in a different room. The query specifically asks about the **living_room** sensors. The living room temperature sensor (`living_room_temp_sensor`) shows continuous, valid data streams with no nulls or errors throughout the entire period (e.g., 22.76 C at 19:35). A fault in the kitchen does not constitute a fault in the living room.

Temperature Trends: living_room_temp_sensor has 293 samples with min/max within normal ranges.

The existence of any sensor malfunction constitutes a system-level anomaly requiring investigation into network health across all devices.

This is an over-interpretation. Smart home networks often have independent reporting intervals or local caching. A single transient communication drop or battery issue in the kitchen (which may be further from the hub or have different power conditions) does not prove systemic instability affecting the living room. The living room sensors are operating normally with high frequency and valid transitions.

occupancy_events: 224 total, with living_room_occupancy having 106 updates.

Attribute frequency: MeasuredValue reported 871 times, showing robust general telemetry.

The living room sensors appear to be functioning correctly, but the context of kitchen failure warrants caution.

I concede that the kitchen sensor had issues, but I reject the implication that this casts doubt on the living room's status without direct evidence. The living room temperature sensor shows stable readings (span ~3C) and the occupancy sensor shows logical transitions consistent with human activity (e.g., occupied during evening hours). There is no evidence of stuck values, impossible transitions, or missing data in the living room specific to the query scope.

Key Events: Living room occupancy transitions from 0 to 1 at 18:13:16 and remains active until late night, matching typical usage.

Chunk C11/C12: Living room temp sensor reports consistent values (22.76 -> 22.54) while kitchen fails.

The living room sensors (temperature and occupancy) are operating normally. The temperature sensor provides consistent, physically plausible readings with no data gaps. The occupancy sensor correctly tracks presence/absence patterns consistent with daily life. The only detected anomaly is in the kitchen temperature sensor, which experienced intermittent data loss; however, this is isolated to the kitchen and does not indicate a failure of the living room equipment.

The kitchen temperature sensor did report null values, indicating a likely local fault or connectivity issue for that specific device.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.

strong - The prosecution explicitly concluded 'no_case' and provided a coherent explanation for the log events (normal user behavior) and metrics (low activity due to room type).

strong - The defense agreed with the prosecution's verdict, providing additional context on usage patterns and clarifying that any potential logic issues were configuration-based rather than sensor faults.

The Prosecutor's explicit declaration of 'no_case' triggers Decision Rule 4, which mandates a normal ruling regardless of other factors.

No security anomaly detected; device logs indicate normal operational behavior consistent with standard user routines.

Explanation: The entrance area contains a contact sensor (`front_door_contact`) and a door lock (`front_door_lock`). The logs show normal operational behavior for both devices. Specifically, at 07:15:20-07:15:23, the contact sensor transitions from false to true (door open) immediately preceding an auto-lock event, which is consistent with a user exiting or entering and leaving the door ajar before locking. There are no stuck values, impossible state transitions, or repeated failures reported for the entrance sensors in the provided chunks. The `room_activity` count of 17 for the entrance is low but non-zero, indicating some activity occurred, likely the morning departure/arrival sequence seen in Key Events.

[2026-06-12T07:15:20] front_door_contact | BooleanState.StateValue = false (raw=False)

[2026-06-12T07:15:22] front_door_contact | BooleanState.StateValue = true (raw=True)

No evidence of malfunction was found for the entrance sensors. The contact sensor correctly reported state changes corresponding to door usage, and the lock operated as expected. The low activity count is consistent with the device being idle for most of the day, not a failure.

The logs show normal operational behavior for both devices. Specifically, at 07:15:20-07:15:23, the contact sensor transitions from false to true (door open) immediately preceding an auto-lock event.

The prosecution correctly identifies the sequence but interprets it as 'normal' without addressing the specific timing anomaly that suggests a potential configuration issue or user error rather than a device fault. The transition from Closed (False) to Open (True) at 07:15:20, followed by an Auto-Lock at 07:15:23, implies the door was left open for 3 seconds after the lock engaged or just before. However, looking at the Key Events, there is a Manual Unlock at 07:15:18. The sequence is: Manual Unlock -> Door Contact Opens (User exits/enters) -> Door Contact Closes? No, the log shows False->True. Wait, let's re-read carefully.

Key Event 07:15:18: LockState=2 (Unlocked).
Key Event 07:15:20: Contact=False (Closed).
Key Event 07:15:22: Contact=True (Open).
Key Event 07:15:23: LockOperation(Auto) -> LockState=1 (Locked).

This sequence is actually physically inconsistent if we assume standard Matter semantics where False=Closed and True=Open. If the door was closed at 07:15:20, why did it open at 07:15:22? And then auto-lock? This looks like a 'jitter' or a momentary glitch in the contact sensor reporting, or the user opened the door slightly while the system was trying to lock. However, the Prosecutor claims this is 'consistent with a user exiting... leaving the door ajar'. This is a plausible human explanation. Is it a fault? Not necessarily. It's a noisy signal or user behavior. The Prosecutor concludes 'no case' based on this. I agree with the verdict of 'normal', but I must challenge the robustness of the 'auto-lock' logic if it triggers while the door is detected as open (if the raw data implies the door was open during the lock attempt). Actually, the log shows Contact=True at 07:15:22, then Lock at 07:15:23. If the lock engages while the door is reported open, that's a safety/config issue, not necessarily a sensor *fault* (it reported what it saw), but it indicates a system logic flaw. However, the prompt asks if the *sensor* is working normally. The sensor reported a state change. That is functional.

Let's look for actual faults. The Prosecutor says 'No stuck values'. Correct. 'Impossible state transitions'. The sequence Unlocked -> Closed -> Open -> Locked is possible (user unlocks, closes door, opens it again, locks it). It's weird but not impossible.

Is there any other evidence? The `room_activity` for entrance is 17. This is low. The Prosecutor attributes this to idle time. This is correct.

Therefore, the Prosecutor's conclusion that the sensor is working normally is defensible. The sensor reported state changes. Whether those state changes corresponded to real physical events or noise is ambiguous, but without evidence of 'stuck' values or total silence, we cannot declare it faulty. The 'Auto-Lock' triggering while the door might be open (if True=Open) is a system policy issue, not a sensor hardware failure. The sensor did its job: it reported 'Open'.

I will concede the main point but refine the narrative around the 'Auto-Lock' interaction being a potential configuration quirk rather than a sensor defect.

The low activity count is consistent with the device being idle for most of the day, not a failure.

Agreed. The `room_activity` metric of 17 is significantly lower than living room (397) or bedroom (353), which aligns with the typical usage pattern of an entrance area in a studio apartment where occupants spend minimal time compared to living/sleeping areas. This statistical variance is expected and does not indicate a communication failure or offline status, especially since discrete events (lock operations, contact changes) were successfully transmitted.

{'room_activity': {'living_room': 397, 'bedroom': 353, 'kitchen': 298, 'bathroom': 52, 'entrance': 17}}

The entrance sensors are functioning within normal parameters. The observed activity cluster around 07:15 corresponds to a morning departure routine involving manual unlocking, brief door movement (possibly causing contact sensor jitter or a momentary opening), and subsequent automatic locking. The low overall activity count is consistent with the spatial function of an entrance hall versus high-traffic living areas. No evidence of hardware failure, stuck states, or communication loss was found.

The prosecution's assessment that the sensor reported valid state transitions is correct.

The low activity count is explained by normal usage patterns.

## Matter Notes
- These logs follow Matter-style smart-home event semantics.
- TemperatureMeasurement.MeasuredValue is represented in centi-degrees Celsius in this benchmark: 2466 means 24.66 C, not 2466 C.
- BooleanState and other protocol booleans should be interpreted using transitions and surrounding events, not naive natural-language assumptions from a single isolated value.
- OccupancySensing.Occupancy uses 0=unoccupied and 1=occupied.
- DoorLock.LockState is an enumerated state; formatted logs may show both the label and the raw code.
- A device-fault conclusion requires direct fault evidence such as stuck values, repeated non-recovery, explicit alarm/fault events, or impossible state transitions. Scaled temperature values alone are not enough.
