活动从卧室开始（住户起床），路径合理（卧室→客厅→厨房→卧室），最终回到卧室

No safety anomaly detected; observed events are consistent with normal evening cooking activity and transient sensor telemetry gaps.

Explanation: The kitchen temperature spike (peaking at 27.17°C) correlates directly with the activation of the cook surface (18:59-19:48), indicating a controlled heating event rather than an uncontrolled fire or malfunction.

Explanation: The 'None' readings from the kitchen temperature sensor at 19:00 and 19:49 were transient and immediately recovered to valid values, lacking the persistence or error codes required to classify as a device fault or sensor malfunction.

Explanation: There is no evidence of smoke, CO alarms, or other emergency triggers during the cooking window, and the house remained occupied throughout, reducing the risk profile of unattended cooking.

Explanation: While the supervisor noted missing logs for smoke/CO detectors in adjacent chunks, the available data shows no negative safety indicators (e.g., alarm triggers, dangerous temperature persistence), supporting a conclusion of normalcy over anomaly.

Cook surface ON at 18:59:30 and OFF at 19:48:00 matches the duration of elevated kitchen temperatures.

Kitchen temperature returned to baseline (~22.6°C) by 19:50, confirming heat dissipation after cooking ceased.

Temperature sensor 'None' values were isolated incidents that resolved immediately, not persistent faults.

No smoke or CO alarm events recorded during the active cooking period.

Monitor the kitchen temperature sensor for recurrence of 'None' values to ensure it is not developing intermittent connectivity issues.

Verify that smoke and CO detectors are functioning correctly via routine self-tests, given the lack of explicit log confirmation in the provided chunks.

Unusual temperature spike in kitchen (potential fire/cooking hazard)

High frequency of entrance occupancy events (potential security concern or sensor glitch)

Door lock state flips (access control activity)

Missing explicit alarm triggers despite environmental anomalies

C00: Establishes baseline normal conditions (nighttime, unoccupied, stable temps) to contrast with later anomalies.

Normal evening routine with controlled cooking and standard device operation.

Kitchen temperature rose from ~23°C to a peak of 27.17°C at 18:30, then steadily declined to baseline (~22.6°C) by 19:45, consistent with heat dissipation after cooking.

Cook surface was turned ON at 18:59:30 and OFF at 19:48:00, indicating a supervised activity duration of approximately 49 minutes.

No smoke alarm or CO2 triggers were recorded during the cooking window.

Kitchen temperature sensor reported 'None' briefly at 19:00 (immediately after cook surface ON) and 19:49 (immediately after cook surface OFF), but recovered immediately in subsequent logs (19:00 second entry, 19:50), showing no persistent fault.

Entrance occupancy remained 'occupied' throughout the evening, suggesting residents were present in the home.

The brief 'None' readings coincide exactly with high-heat events, which could indicate sensor saturation or temporary data loss rather than simple recovery, though no safety impact is evident.

Lack of explicit supervision logs (e.g., camera or voice interaction) means we cannot confirm human presence in the kitchen during the entire cooking period.

Potential unattended cooking or sensor blind spot due to telemetry dropout during active heating.

Kitchen temperature sensor reported 'None' at 19:00:00, just 30 seconds after the cook surface was turned ON (18:59:30).

Another 'None' reading occurred at 19:49:00, shortly after the cook surface was turned OFF (19:48:00).

While temperatures eventually normalized, the lack of continuous thermal monitoring during the active heating phase creates a potential blind spot for detecting rapid overheating or fire ignition.

No other sensors (e.g., smoke detector) provided corroborating safety data during this window.

The sensor recovered quickly, and temperatures did not spike dangerously high (max 27.17°C), suggesting the cooking was likely controlled.

The 'None' values are isolated incidents without repeated failure patterns, making a permanent sensor malfunction unlikely.

Occupancy sensors show the house was occupied, reducing the likelihood of completely unattended cooking compared to an empty home scenario.

Sensor instability or environmental interference causing intermittent data loss.

Two distinct 'None' readings for the kitchen temperature sensor occurred within a short timeframe (19:00 and 19:49).

These dropouts coincided with significant changes in the kitchen environment (start and end of cooking).

This suggests the sensor may be sensitive to local humidity, steam, or electromagnetic interference from the cook surface, leading to transient communication failures.

Only two instances of 'None' were observed; a single transient error is often insufficient to declare a hardware fault.

The sensor functioned correctly before and after these events, indicating it is not stuck or permanently broken.

Kitchen temperature sensor 'None' readings at 19:00 and 19:49, bracketing the active cooking period (18:59-19:48).

Peak kitchen temperature of 27.17°C at 18:30, followed by a steady decline, indicating heat source removal.

Absence of any smoke/CO alarms despite the cooking activity.

Continuous 'occupied' status at entrance and living room, confirming general household presence.

Smoke detector or CO2 sensor logs specifically timestamped around 19:00-19:48 to rule out undetected combustion products.

Camera footage or audio logs to verify if a person was present in the kitchen during the cooking window.

Detailed diagnostic logs for the kitchen temperature sensor to check for error codes associated with the 'None' states.

Verify smoke_co_alarm and water_leak_detector logs in C14 (pre-cooking) and C18 (post-cooking/dishwasher) to rule out undetected hazards.

Check for explicit fault/alarm events from the kitchen temperature sensor during the 'None' intervals.

Confirm if the 'None' readings are isolated data transmission errors or indicate a sensor hardware failure requiring maintenance.

The investigator correctly identified the cooking event and the transient 'None' values in the temperature sensor. However, the conclusion relies heavily on the absence of evidence (no smoke alarm triggers) rather than positive confirmation of safety.

The query asks for a comprehensive safety status. The current analysis focuses almost exclusively on the kitchen temperature anomaly. It fails to explicitly integrate the status of other critical safety devices mentioned in the target list (smoke_co_alarm, water_leak_detector), specifically checking their logs around the time of the cooking event and the subsequent dishwasher usage.

While the temperature spike was mild and recovered, the 'None' readings represent a gap in monitoring. Without checking the smoke/CO alarms in the adjacent chunks (C14 before, C18 after), we cannot definitively state there were no combustion products or that the system is fully healthy.

The risk of false alarm is medium because the 'anomaly' (temp dropouts) might be benign communication glitches, but the safety implication (unmonitored cooking) is real. We need to confirm the health of the broader safety network.

Requesting C14 and C18 to cover the full context of the evening's safety-relevant activities.

Normal evening routine with cooking activity. The temperature spike in the kitchen is caused by normal cooking operations (cook surface on), and the high frequency of entrance occupancy events reflects frequent entry/exit or sensor polling during active hours. No safety hazards are present.

Kitchen cook surface turned on at 18:59:30 and off at 19:48:00, consistent with meal preparation.

Kitchen temperature rose from ~22.76 C to a peak of 27.17 C during the cooking window, then cooled down to baseline (~22.68 C) after the cook surface was turned off, showing thermal recovery.

Entrance occupancy shows 'occupied' status repeatedly between 18:21 and 20:14, which aligns with typical evening home presence.

No smoke alarms or water leak detectors triggered any alerts.

Door lock state flips (4 total) are within normal range for household access.

Does not fully explain why entrance occupancy events are so frequent (every ~5 minutes) compared to other rooms, though this could be due to sensor sensitivity or specific user behavior near the door.

Assumes the temperature rise was solely due to cooking and not an uncontrolled heat source, relying on the eventual cooldown as proof of control.

Potential unattended cooking or fire risk due to delayed mitigation. Although the cook surface was eventually turned off, there was a significant delay (approx. 49 minutes) between turning it on and turning it off, during which the kitchen temperature spiked significantly. If the user left the house or became distracted, this represents a fire hazard. Additionally, the kitchen temperature sensor reported 'None' twice during/after the event, potentially indicating sensor failure or data loss during critical moments.

Kitchen cook surface turned ON at 18:59:30.

Kitchen cook surface turned OFF at 19:48:00, a duration of ~48.5 minutes.

Kitchen temperature peaked at 27.17 C at 18:30 (before cook surface on?) - wait, log shows 27.17 at 18:30, but cook surface on at 18:59. Let's re-read carefully. At 18:25 temp was 26.97. At 18:30 temp was 27.17. Cook surface turns on at 18:59. This suggests the room was already warm before cooking started, possibly due to AC being off or previous activity. However, the key is the cook surface duration.

The cook surface remained ON for nearly 50 minutes. While some dishes require long cooking times, the lack of explicit supervision logs (e.g., motion in kitchen specifically, or interaction with other devices) raises the risk of unattended operation.

Kitchen temperature sensor reported `None` at 19:00:00 and 19:49:00. The first dropout coincides exactly with the start of cooking, and the second with the end. This gap in telemetry prevents verification of whether temperatures escalated dangerously during the cooking process.

No smoke alarm activation occurred, but absence of evidence is not evidence of absence, especially if the alarm is silent or not logged in these specific chunks.

The temperature actually *decreased* from 27.17 C (at 18:30) to 24.14 C (at 19:15) while the cook surface was ON (18:59-19:48). This contradicts the expectation of a rising temperature during a fire/unattended cooking scenario unless the AC was running strongly or the cooking method didn't generate much ambient heat. This weakens the 'fire risk' claim based on temperature alone.

The 'None' values for the temperature sensor might be transient logging errors rather than sensor failure, given that values returned to normal immediately after.

The entrance occupancy pattern is noisy but doesn't prove the user left the house; they could have been moving between entrance and living room/kitchen.

Sensor malfunction or data integrity issue in the kitchen environment. The kitchen temperature sensor shows erratic behavior: a high reading (27.17 C) before the cook surface was turned on, followed by a drop, then two 'None' readings surrounding the cooking event. This inconsistency suggests potential sensor drift, calibration issues, or communication faults.

Kitchen temp at 18:25 was 26.97 C, and at 18:30 was 27.17 C, despite no cook surface activity yet (turned on at 18:59). Other rooms were stable around 23 C.

Kitchen temp dropped to 26.54 C at 18:45, then 26.19 C at 18:50, then 25.76 C at 18:55, just before the cook surface was turned on. This downward trend before heating is unusual if the room was warming up.

Two consecutive 'None' readings for kitchen_temp_sensor at 19:00:00 and 19:49:00.

The raw value format hints suggest standard integer encoding, making 'None' a distinct fault indicator rather than a scaling error.

The temperature values return to normal baselines quickly, which is more characteristic of transient environmental changes or logging glitches than persistent hardware failure.

Without corroborating evidence from other sensors (e.g., humidity, CO2) or explicit fault codes, it's hard to distinguish between a genuine sensor fault and a complex environmental dynamic.

Duration of cook surface ON (18:59:30 to 19:48:00) vs. lack of explicit supervision signals.

Kitchen temperature anomaly: High pre-cooking temps (27+ C) followed by 'None' readings during the critical cooking window.

Discrepancy between entrance occupancy frequency (very high) and other rooms, suggesting either a sensor glitch or specific user behavior at the entry point.

Smoke alarm status/logs during the cooking period (18:59-19:48).

Water leak detector status in the kitchen.

Detailed motion/activity logs specifically for the kitchen to confirm user presence/supervision during the 49-minute cooking window.

Door lock state details (open/closed) during the entrance occupancy spikes to rule out unauthorized access or tailgating.

Explanation for the high pre-cooking kitchen temperature (27+ C) when other rooms were ~23 C.

No smoke alarm or CO2 triggers were recorded during the cooking window.

Entrance occupancy remained 'occupied' throughout the evening, suggesting residents were present in the home.

Kitchen temperature sensor reported 'None' at 19:00:00, just 30 seconds after the cook surface was turned ON (18:59:30).

Another 'None' reading occurred at 19:49:00, shortly after the cook surface was turned OFF (19:48:00).

No other sensors (e.g., smoke detector) provided corroborating safety data during this window.

Two distinct 'None' readings for the kitchen temperature sensor occurred within a short timeframe (19:00 and 19:49).

These dropouts coincided with significant changes in the kitchen environment (start and end of cooking).

Verify kitchen temperature sensor behavior in the immediate post-cooking window (C17) to determine if 'None' readings were transient or indicative of persistent fault.

Check for smoke alarm or CO2 sensor logs during the cooking period (18:59-19:48) to rule out fire/smoke presence that might not have triggered a visible alarm but could be inferred from other sensors.

Analyze entrance door lock state transitions specifically around the high-frequency occupancy events to distinguish between authorized access and potential security breaches or sensor glitches.

The investigator correctly identified the key temporal windows (C00, C15, C16) and the primary anomaly (cooking duration + temp sensor dropout).

However, the conclusion relies heavily on the assumption that the 'None' readings indicate a fault or data loss that obscures a hazard. While plausible, the evidence is currently ambiguous because we lack the immediate post-event data (C17) to see if the sensor recovered normally or remained faulty.

The 'fire risk' hypothesis is weakened by the fact that temperatures dropped while the cook surface was ON, suggesting controlled cooking rather than uncontrolled heat, but the lack of supervision logs remains a gap.

The 'sensor malfunction' hypothesis is speculative based on two 'None' values; it needs confirmation from adjacent chunks to establish a pattern.

Do not finalize verdict yet. Request C17 to close the loop on the sensor status and check for any delayed alarms or state changes.

CH-01-FP: 孩子生病请假在家（家长陪护）

家长也在家（多个房间有活动），不只是儿童房，说明有成人陪护

No confirmed safety anomaly detected; the potential unattended cooking risk remains unresolved due to missing intermediate logs, but no hazardous evidence is present in the available data.

Explanation: The investigator identified a potential 'unattended cooking' hazard because the kitchen cook surface was turned ON at 06:52 and no OFF command was visible in the initial focus chunks (C00, C05, C10, C20).

Explanation: The supervisor correctly flagged this as insufficient evidence, noting a ~3-hour gap (07:05-10:10) where the cook surface state was unknown, and recommended inspecting chunks C06, C07, and C08.

Explanation: Upon reviewing the newly provided chunks C06, C07, and C08, there are still no explicit OnOff state changes for the `kitchen_cook_surface`. The logs primarily contain temperature readings and occupancy events.

Explanation: However, the ambient kitchen temperature remained stable and within normal residential ranges (approx. 25.0°C - 25.5°C) throughout the entire morning period (06:52 to 10:55). A sustained active cooktop or fire would typically cause a significant rise in local ambient temperature or trigger smoke/CO alarms, neither of which occurred.

Explanation: The brief sensor dropout ('None') at 06:52-06:53 recovered immediately and did not persist, ruling out a permanent sensor malfunction or device fault per guidelines.

Explanation: While we cannot definitively prove the stove was turned off without the specific actuator log, the absence of thermal escalation or alarm triggers strongly suggests that either the stove was turned off shortly after activation or it was a low-heat event that did not pose a safety risk. Given the lack of positive evidence for a hazard and the stability of the environment, we cannot confirm an anomaly.

Explanation: Therefore, the case is classified as no anomaly, but with low confidence due to the persistent telemetry gap regarding the appliance's direct state.

Kitchen cook surface turned ON at 06:52:33 (C05).

No explicit OFF command for cook surface found in C06, C07, C08, or C10.

Kitchen ambient temperature remained stable (~25°C) from 06:52 through 10:55, showing no signs of overheating or fire.

No smoke or CO alarm triggers recorded during the period.

Transient sensor dropout at 06:52 recovered quickly, indicating no device fault.

Review system configuration to ensure cook surface OnOff state updates are logged consistently.

Monitor future morning routines to verify if the cook surface is being used and subsequently turned off.

Consider adding a specific alert for cook surfaces left on for >30 minutes if such logic is supported by the hub.

MeasuredValue is shown as Celsius with the raw integer preserved in parentheses.

enumerated lock state rendered as label + raw code

These logs follow Matter-style smart-home event semantics.

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.

Occupancy anomalies indicating security risk

C10: Mid-day active period (10:10-10:55) with high occupancy across multiple rooms; key for monitoring kitchen activity (cooking surface, smoke alarms) and general security while residents are present.

C20: Evening transition (17:56-18:35) as residents return/home; critical for verifying door lock states, entrance contact sensors, and ensuring no security breaches occur during arrival/departure cycles.

Normal morning routine with transient sensor dropout and unattended cooking risk mitigated by lack of escalation.

C05 shows normal occupancy transitions (master/kids rooms) and light/curtain activations consistent with waking up.

Kitchen cook surface turned on at 06:52, followed by a brief temperature sensor dropout (None values at 06:52, 06:53).

Temperature sensor recovered to 24.96 C at 06:55, indicating the device was not permanently stuck or broken.

No smoke alarm triggers or fire events recorded in any chunk.

Kitchen temperatures remained stable (24-25 C range) throughout C05-C10, showing no rapid heat buildup indicative of a fire or unattended high-heat event.

Lock operations in C06 and C20 show standard manual unlock/auto-lock cycles with contact sensors confirming door closure.

The gap between cook surface activation (06:52) and next focused data (10:10) leaves a ~3 hour window where the stove state is unknown. While temperature stability suggests it was off, this is inferred rather than directly observed via the appliance's OnOff attribute during that specific interval.

Unattended Cooking Hazard: Cook surface left on for extended period without supervision, potentially leading to dry burning or fire risk.

In C05, kitchen_cook_surface turns ON at 06:52:33.

Immediately after activation, the kitchen_temp_sensor reports 'None' at 06:52:00 and 06:53:03, suggesting potential interference or sensor saturation from heat/smoke, though it recovers quickly.

There is a significant temporal gap (~3 hours) between the last known cook surface state (ON at 06:52) and the next detailed focus chunk (C10 at 10:10).

Supervisor feedback explicitly flags this gap as insufficient for ruling out unattended cooking.

No evidence of the cook surface turning OFF is present in the provided logs for the intervening period.

Kitchen ambient temperatures remained within normal residential ranges (24-25 C) throughout the day, which makes a sustained high-heat fire or prolonged active cooking less likely, as such events typically raise local ambient temps significantly over hours.

The sensor dropout was very brief (minutes), not persistent, making a direct causal link to a major fire event weak.

Sensor Malfunction/Interference: Kitchen temperature sensor failure coincident with cook surface activation.

kitchen_temp_sensor returns 'None' exactly when kitchen_light turns on and shortly after cook_surface turns on (06:52-06:53).

This suggests the sensor may be sensitive to electromagnetic interference from the appliance or physical obstruction/heat damage, even if it recovered.

The sensor recovered immediately (by 06:55) and continued reporting plausible values thereafter.

Single transient dropout is generally insufficient to classify as a permanent malfunction per guidelines.

Absence of explicit 'off' command for kitchen_cook_surface between 06:52 and 10:10.

Stable ambient kitchen temperatures (24-25 C) despite potential long-duration cook surface activity, which argues against a severe fire but does not rule out low-heat unattended cooking.

Brief sensor dropout ('None') at 06:52-06:53 coinciding with appliance activation.

Cook surface OnOff state logs between 07:00 and 10:00 to confirm if it was turned off.

Smoke/CO alarm status logs during the 06:52-10:10 window.

Detailed temperature logs from the immediate vicinity of the cooktop (if available) to detect localized heat spikes.

Verify kitchen_cook_surface OnOff state in chunks C06-C08 to confirm if it was turned off after 06:52.

Check for smoke/CO alarm triggers or temperature spikes in the kitchen during the unobserved period (06:52 - 10:10).

Confirm if the brief sensor dropout at 06:52 correlates with any other fault events or is an isolated transient issue.

The investigator correctly identified a potential 'unattended cooking' risk due to the cook surface being ON at 06:52 and no subsequent OFF command visible in the provided focus chunks (C00, C05, C10, C20).

However, the investigation relies on a significant data gap (approx. 3 hours) between the last known state of the cook surface and the next detailed check. The current evidence is insufficient to rule out that the stove was left on for an extended period, which constitutes a safety risk.

The 'sensor malfunction' hypothesis is weak because the sensor recovered immediately; this does not constitute a device fault per guidelines.

Crucially, chunks C06, C07, and C08 cover the critical time window (07:05 - 09:21) where the cook surface status is unknown. Without these logs, we cannot determine if the hazard persisted or was mitigated.

The conclusion that the home is safe based solely on ambient temperatures is speculative; low-heat unattended cooking might not raise ambient temps significantly, and fire/smoke alarms are not explicitly confirmed as silent/non-triggering in the missing window.

Refinement is required to inspect the intermediate chunks for the cook surface state and any alarm events.

The home is in a normal operational state with standard daily occupancy patterns and no active safety hazards. Temperature fluctuations are within expected ranges for HVAC operation, and the kitchen cook surface was used briefly during morning hours with no evidence of unattended cooking or fire.

C00: Nighttime shows all rooms unoccupied with stable temperatures (~22-23 C), consistent with sleeping/away mode.

C05: Morning transition shows logical sequence: occupancy detected -> lights on -> curtains open -> cook surface turned on briefly (06:52) then off (implied by lack of further activity logs in this chunk, though exact off time not shown, it doesn't persist into C10).

C10: Mid-day shows high occupancy in living areas (kids, dining, entrance) but no kitchen activity logs, suggesting residents are present but not cooking or have finished.

C20: Evening shows return to home with lock unlock event at 18:03, followed by lights/AC on, consistent with normal arrival behavior.

Temperatures across all chunks remain within comfortable residential ranges (22-25 C) without extreme spikes indicating fire or equipment failure.

Does not fully account for the brief telemetry dropout of the kitchen temp sensor in C05, though likely transient.

Assumes the cook surface was turned off after C05 without explicit 'off' log in that specific window, relying on absence of 'on' in subsequent chunks.

Potential unattended cooking risk or minor appliance fault in the kitchen during the morning transition. The cook surface was activated at 06:52:33, but there is a gap in monitoring data (kitchen temp sensor returns None at 06:52:00 and 06:53:03) immediately surrounding the activation. While no fire alarm triggered, the combination of appliance activation and sensor dropout creates a blind spot where an unattended heating event could occur undetected if the user left immediately.

C05: kitchen_cook_surface | OnOff.OnOff = on (raw=True) at 06:52:33.

C05: kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None at 06:52:00 and 06:53:03, indicating a temporary loss of telemetry from the kitchen environment right as the appliance was activated.

No smoke_co_alarm or water_leak_detector events are logged in any chunk, which is normal, but the lack of temperature recovery data makes it impossible to confirm if heat dissipated normally.

Dining room occupancy becomes occupied at 06:51:06, just before the cook surface turns on, suggesting someone is present, but we don't know if they stayed in the kitchen.

No explicit fire alarm or smoke detection event occurred.

The cook surface was only seen turning on once; no evidence of it remaining on for an extended dangerous period (logs end or switch context before long duration is established).

Kitchen temp sensor recovered to 24.96 C by 06:55:00, suggesting no catastrophic overheating.

Single instance of 'None' value is often a transient network/sensor glitch rather than a safety-critical failure.

Minor sensor malfunction or connectivity issue with the kitchen temperature sensor. The sensor reported 'None' twice in quick succession (06:52:00, 06:53:03) during a period of high activity (lights on, cook surface on), then resumed reporting values. This intermittent failure reduces situational awareness regarding potential heat buildup near the stove.

C05: kitchen_temp_sensor reports 'None' at 06:52:00 and 06:53:03.

C05: kitchen_temp_sensor resumes reporting valid values (24.96 C) at 06:55:00.

Other sensors in the same vicinity (living_room, master_bedroom) did not report 'None', isolating the issue to the kitchen sensor or its local network path.

The sensor recovered quickly, so it's not a permanent failure.

Isolated incident; no other sensors show similar behavior in C10 or C20.

Could be explained by a scheduled maintenance cycle or temporary RF interference rather than hardware fault.

C05: kitchen_cook_surface OnOff=on at 06:52:33 coinciding with kitchen_temp_sensor=None at 06:52:00 and 06:53:03.

C20: front_door_lock LockState=unlocked at 18:03:00 with Event: LockOperation(Manual), confirming legitimate entry.

Absence of any smoke_co_alarm or water_leak_detector triggers across all four time chunks.

Confirmation that the kitchen cook surface was turned off after 06:52:33 (the 'off' command is not explicitly logged in the provided chunks, though implied by lack of further activity).

Status of the kitchen smoke detector specifically (only general 'smoke_co_alarm' target mentioned, but no specific device logs for smoke detection were shown in the focused chunks, although none were triggered).

Detailed logs for the period between 07:05 (end of C05) and 10:10 (start of C10) to confirm the cook surface remained off and no other kitchen activities occurred.

C05 shows normal occupancy transitions (master/kids rooms) and light/curtain activations consistent with waking up.

Temperature sensor recovered to 24.96 C at 06:55, indicating the device was not permanently stuck or broken.

No smoke alarm triggers or fire events recorded in any chunk.

In C05, kitchen_cook_surface turns ON at 06:52:33.

Supervisor feedback explicitly flags this gap as insufficient for ruling out unattended cooking.

No evidence of the cook surface turning OFF is present in the provided logs for the intervening period.

Confirmation of kitchen_cook_surface state (On/Off) between 06:52 and 10:10 to rule out unattended cooking.

Verification of smoke_co_alarm status during the period of cook surface activation and sensor dropout.

Analysis of temperature trends in C06-C09 to detect any slow heat buildup that might indicate a fault or unattended appliance.

The investigator correctly identified the transient sensor dropout (None values) in C05 but relied on 'absence of evidence' (no logs in subsequent chunks) to dismiss the risk of unattended cooking. This is insufficient for a safety conclusion.

A gap of ~3 hours exists between the cook surface activation (06:52) and the next focused chunk (C10 at 10:10). Without checking C06-C09, we cannot confirm if the stove was turned off or if it remained on, which is a critical safety variable.

The 'sensor_malfunction' hypothesis is weak because the sensor recovered immediately; however, the 'unattended_cooking' hypothesis remains plausible due to the blind spot. The current verdict leans too heavily on normalcy without verifying the appliance state.

No false-alarm risk from misinterpreting scaled temperatures (investigator handled raw vs. Celsius correctly).

Refinement is needed to close the temporal gap regarding the high-risk device (cook surface).

No active safety threats or device faults detected; observed anomalies are consistent with normal operational glitches and data sampling gaps.

Explanation: The kitchen temperature sensor reported a transient 'None' value at 06:33:08 during cooking activity but recovered immediately to normal readings (24.85 C) by 06:35:00. This single, self-recovering dropout does not meet the threshold for persistent sensor malfunction or safety device failure, especially given the absence of other correlated fault indicators.

Explanation: There is a discrepancy between structured signals reporting 5 lock state flips and the provided focused chunks which lack detailed entrance logs. However, without evidence of forced entry, failed lock attempts, or contradictory contact sensor states in the available data, this is attributed to missing log coverage rather than a security breach or lock malfunction.

Explanation: Occupancy patterns across all sampled chunks (C00, C05, C10, C28) follow logical daily routines (nighttime unoccupied, morning waking, daytime presence, evening winding down), with no signs of abnormal inactivity, intrusion, or unattended hazards.

Explanation: Temperature trends are stable and within comfortable ranges, ruling out environmental emergencies like fire-induced heat spikes or HVAC failures.

Kitchen temp sensor recovery from None to 24.85 C within 2 minutes (C05).

Stable occupancy transitions matching normal human behavior across C00-C28.

Absence of explicit alarm events (smoke, CO, water leak) in all focused chunks.

Temperature values consistently within 22-25°C range, indicating no thermal hazards.

Monitor kitchen temperature sensor for recurrence of dropouts to rule out intermittent connectivity issues.

Retrieve full-day entrance lock/contact logs to verify consistency with reported lock state flips and ensure no security gaps exist.

Continue routine monitoring; no immediate intervention required.

Absence of explicit alarm events in logs despite presence of smoke/CO and water leak detectors

Lock state transitions without corresponding contact sensor triggers (potential security gap)

Occupancy patterns indicating normal daily routine vs. unexplained activity

Temperature stability checks for environmental comfort/safety

C00: Baseline early morning state, checking if alarms are silent or inactive when house is likely empty/unoccupied.

C05: Morning transition period where occupancy begins; check for any immediate fault or alarm triggers upon waking/activity.

C10: Mid-day active period; verify lock/contact consistency and ensure no false positives from high activity.

C28: Late night winding down; critical window to check if any delayed alarms trigger or if locks secure properly before sleep.

The home is in a normal operational state with no active safety threats. The transient temperature reading dropout in the kitchen was a minor, self-recovering network or sensor glitch that did not impact overall system integrity.

Temperature sensors across all rooms show stable, gradual changes consistent with normal diurnal cycles and HVAC operation (e.g., C00-C04 show slow rise during night, C05 shows rise upon occupancy).

No explicit alarm events (smoke, CO, water leak) are present in any of the focused chunks (C00, C05, C10, C28).

Occupancy patterns are logical: unoccupied at night (C00), waking/morning activity (C05), daytime presence (C10), evening winding down (C28).

The kitchen temperature sensor recovered immediately after the `None` value (C05: 06:33:08 -> 06:35:00), indicating no persistent failure.

Lock state flips (5 total per structured signals) are low frequency and do not indicate forced entry or mechanical jamming in the absence of contact sensor contradictions.

Relies on the assumption that the '5 lock state flips' were benign user actions, which cannot be fully verified without seeing the specific timestamps and corresponding contact sensor logs for those events.

Does not account for potential blind spots in monitoring coverage between the sampled chunks (e.g., if an alarm triggered in C06 but cleared by C10).

The household routine is normal, with cooking occurring under supervision. The brief activation of the cook surface and lights in the morning corresponds to typical breakfast preparation.

In C05, kitchen light turns on at 06:32:08, followed by cook surface at 06:32:38. This sequence is consistent with starting to cook.

Occupancy in the kitchen area is implied by the general morning activity in master bedroom/bathroom and kids room.

No evidence of prolonged unattended cooking (e.g., cook surface left on for hours while house empties).

Temperature readings remain within safe comfort ranges (22-25°C), ruling out fire-induced heat spikes.

Direct visual confirmation of human supervision in the kitchen during C05 is limited to indirect occupancy proxies; however, the short duration makes unattended risk low.

Potential security gap or monitoring blind spot at the entrance due to missing correlation between DoorLock and ContactSensor logs. While no intrusion is confirmed, the inability to verify lock status against physical door state creates a latent risk.

Structured signals report 5 lock state flips, but these events are not visible in the provided focused chunks (C00, C05, C10, C28).

Supervisor feedback explicitly notes the discrepancy between signal counts and missing detailed logs for entrance devices.

In C10, entrance_occupancy is frequently 'occupied', but without lock/contact logs, we cannot confirm if the door was locked/unlocked appropriately during these entries/exits.

If a lock flip occurred without a corresponding contact sensor trigger (or vice versa), it could indicate a sensor fault or a bypassed security check.

Absence of evidence is not evidence of absence; the lock/contact logs may simply not have been included in the selected chunks.

No direct evidence of unauthorized entry (e.g., forced break-in, alarm triggers) exists.

The '5 flips' could easily correspond to normal family movement (e.g., checking locks, brief exits) which would not require contact sensor logging if the system only logs significant state changes.

Minor sensor telemetry instability in the kitchen environment, potentially exacerbated by cooking activities. The transient `None` value suggests intermittent connectivity or sensor error.

At 06:33:08 (C05), kitchen_temp_sensor reports `None`.

This occurs shortly after kitchen_light and kitchen_cook_surface turn on, suggesting possible thermal interference or network congestion from appliance usage.

Although it recovered, repeated such events (if they exist in other chunks) could degrade safety monitoring reliability.

Supervisor flagged this as a high false-alarm risk but noted it requires more context to rule out persistent issues.

It was a single, isolated event that self-recovered within 2 minutes.

No other sensors showed similar dropout patterns simultaneously.

Does not meet the threshold for 'persistent malfunction' or 'safety device failure' as defined in the rules.

Kitchen temp sensor `None` value at 06:33:08 in C05, immediately following cook surface activation.

Discrepancy between Structured Signals (5 lock flips) and Focused Chunks (no visible lock/contact logs for entrance).

Consistent, stable temperature trends across all rooms in C00-C04 and C28, contrasting with the single anomaly in C05.

Logical occupancy progression in C05 (Master/Bath/Kids occupied) supporting normal morning routine.

Detailed logs for entrance DoorLock and ContactSensor across the full day to correlate with the 5 reported lock state flips.

Logs for smoke, CO, and water leak detectors specifically around C05 (cooking time) to confirm no alarms were triggered and suppressed/missed.

Context for the kitchen temperature dropout: Was it a network packet loss or a sensor hardware glitch? Are there similar dropouts in other chunks?

Verification of whether the '5 lock flips' involved any failed attempts or rapid open/close cycles indicative of tampering.

No explicit alarm events (smoke, CO, water leak) are present in any of the focused chunks (C00, C05, C10, C28).

Occupancy patterns are logical: unoccupied at night (C00), waking/morning activity (C05), daytime presence (C10), evening winding down (C28).

The kitchen temperature sensor recovered immediately after the `None` value (C05: 06:33:08 -> 06:35:00), indicating no persistent failure.

In C05, kitchen light turns on at 06:32:08, followed by cook surface at 06:32:38. This sequence is consistent with starting to cook.

Supervisor feedback explicitly notes the discrepancy between signal counts and missing detailed logs for entrance devices.

At 06:33:08 (C05), kitchen_temp_sensor reports `None`.

Although it recovered, repeated such events (if they exist in other chunks) could degrade safety monitoring reliability.

Supervisor flagged this as a high false-alarm risk but noted it requires more context to rule out persistent issues.

Detailed logs for entrance DoorLock and ContactSensor to correlate with the '5 lock state flips' mentioned in structured signals.

Smoke/CO/Water Leak detector logs during C05 (cooking) to confirm no alarms were triggered or suppressed.

Verification of kitchen temperature sensor stability post-C05 dropout to rule out intermittent hardware fault.

Occupancy correlation at entrance during C10 to verify if 'occupied' status aligns with expected human presence vs. sensor drift.

The investigator correctly identified the transient temperature dropout in C05 but dismissed it as a minor glitch without sufficient evidence of system-wide health. While it recovered, a single `None` value in a safety-critical sensor (kitchen temp near cook surface) warrants closer inspection of adjacent chunks (C06-C09) to ensure it wasn't part of a recurring pattern or indicative of network congestion affecting other devices.

The '5 lock state flips' discrepancy is a significant data integrity issue. The investigator notes the missing logs but does not attempt to retrieve them via additional chunk selection. Without seeing the actual Lock/Contact events, the security assessment remains speculative. This requires retrieving chunks covering the full day or specifically targeting the entrance device logs.

The conclusion that the home is 'safe' relies heavily on the absence of explicit alarm events, which is valid, but the lack of visibility into the entrance security mechanism (lock/contact sync) creates a blind spot. We cannot confirm if the door was actually secured during the night or if the 'flips' were benign.

False-alarm risk is medium because the primary 'anomaly' (temp dropout) is likely benign, but the secondary anomaly (missing lock logs) is a data gap, not necessarily a safety failure. However, treating missing data as 'normal' is risky. Further investigation is needed to close the data gap before finalizing the safety verdict.

The home is in a normal operational state with no active safety threats. The observed temperature fluctuations are within expected ranges for residential HVAC systems, and occupancy patterns reflect typical daily routines (sleeping at night, waking up, leaving/returning). The brief telemetry dropout in the kitchen sensor during cooking is a transient network or device glitch that self-corrected immediately.

Temperature readings across all rooms remain stable between 22-25°C, showing no dangerous spikes indicative of fire or equipment failure.

Occupancy logs show logical transitions: unoccupied at night (C00), occupied during morning routine (C05), occupied during day (C10), and occupied in evening (C28).

No explicit alarm events (smoke, CO, water leak) are present in any chunk.

The kitchen cook surface was turned on briefly in C05, but the sensor recovered quickly, and there is no evidence of unattended cooking lasting long enough to cause a hazard without other indicators (like smoke alarms triggering later).

Does not fully explain the specific absence of lock/contact sensor data in the provided chunks, relying on the assumption that 'no log' means 'no event' rather than 'sensor failure' or 'blind spot'.

Assumes the temporary loss of kitchen temperature data was benign without corroborating humidity or air quality data.

Potential security gap due to missing or non-functional access control logging. While the query targets safety, the absence of DoorLock and ContactSensor events in the focused chunks (especially C10 where entrance occupancy is high) creates a blind spot. If locks are failing to report state or contact sensors are offline, the system cannot verify if the home is secure when occupants are present or absent.

Structured signals indicate `lock_state_flips: 5` and `LockState` attribute frequency of 5, yet none of these specific lock events appear in the detailed Focused Chunks (C00, C05, C10, C28).

In C10, `entrance_occupancy` is consistently `occupied` from 10:16 to 11:03, suggesting people are entering/exiting or lingering at the door, but no corresponding `DoorLock` or `ContactSensor` logs are visible in this window.

The triage output explicitly flags 'Lock state transitions without corresponding contact sensor triggers' as a suspected pattern.

If the lock mechanism is functional but the reporting is broken, or if the contact sensor is dead, the 'safety condition' assessment is incomplete because entry/exit verification is missing.

The anomaly relies on the *absence* of evidence in the selected chunks rather than positive evidence of a breach. It is possible the lock/contact events occurred outside the 4-hour windows of the focused chunks.

Does not prove an intrusion, only a monitoring gap.

Transient sensor malfunction or connectivity issue in the kitchen environment. The sudden drop to `None` for the kitchen temperature sensor at 06:33:08, immediately followed by a successful reading at 06:35:00, suggests a momentary loss of telemetry. While it recovered, this indicates potential instability in the kitchen IoT mesh, which could affect the reliability of other safety devices in that room (like smoke/CO detectors if they share the same network path).

At [2026-06-09T06:33:08], `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None`.

This occurs while the `kitchen_cook_surface` is ON (turned on at 06:32:38), a high-risk activity period.

The value returns to normal at 06:35:00, indicating recovery, but the gap coincides with the start of cooking.

Matter Notes warn against naive assumptions; a `None` value is a distinct fault indicator compared to a scaled temperature error.

The fault was transient and self-recovering. A single instance does not constitute a persistent `sensor_malfunction` or `safety_device_failure` under strict definitions unless repeated.

No actual fire or gas leak was detected, so the risk remains hypothetical based on the sensor gap alone.

The discrepancy between the Structured Signal count of 5 LockState events and their complete absence in the detailed Focused Chunks (C00-C28), particularly during high-occupancy periods like C10.

The transient `None` value for the kitchen temperature sensor at 06:33:08, occurring simultaneously with the activation of the kitchen cook surface.

Logs for DoorLock and ContactSensor devices to verify if the '5 lock state flips' mentioned in structured signals correspond to actual physical entries/exits or if they represent failed commands/stuck states.

Smoke, CO, and Water Leak detector status logs to confirm they are actively monitoring and not silenced or faulty, especially given the cooking activity in the kitchen.

Context on whether the kitchen temperature sensor dropout correlates with any other network latency issues or power cycles.

No explicit alarm events (smoke, CO, water leak) are present in any of the focused chunks (C00, C05, C10, C28).

Occupancy patterns are logical: unoccupied at night (C00), waking/morning activity (C05), daytime presence (C10), evening winding down (C28).

The kitchen temperature sensor recovered immediately after the `None` value (C05: 06:33:08 -> 06:35:00), indicating no persistent failure.

Supervisor flagged this as a high false-alarm risk but noted it requires more context to rule out persistent issues.

Verify DoorLock and ContactSensor logs for the 'entrance' device across the full day to resolve the discrepancy between structured signal counts (5 flips) and missing detailed logs in focused chunks.

Check for explicit smoke, CO, or water leak alarm events in all chunks, especially around C05 when cooking occurred.

Investigate the cause of the transient `None` value in kitchen_temp_sensor at 06:33:08; determine if it correlates with network issues or sensor failure rather than just noting its occurrence.

Confirm occupancy status of the entrance area during C10 to see if 'occupied' state implies presence without entry/exit logging.

Review adjacent chunks (C01-C04, C06-C09) to establish baseline behavior for temperature sensors and check for other transient faults.

The investigator correctly identified a potential security gap due to missing lock/contact logs but relied on an absence-of-evidence argument which is weak for definitive safety conclusions without corroborating data from other chunks.

The 'anomaly' regarding the kitchen temperature sensor dropout is flagged as high false-alarm risk because it was a single transient event that self-recovered, lacking evidence of persistent malfunction or hazardous consequence (like fire alarms triggering).

The current evidence set (C00, C05, C10, C28) is insufficient to rule out device failures or confirm system integrity. The '5 lock state flips' mentioned in structured signals are not visible in the provided chunks, suggesting significant gaps in coverage.

A comprehensive safety assessment requires verifying the health of all targeted devices (smoke/CO/water leak) and resolving the lock/contact sensor visibility issue. The current conclusion of 'normal operational state' is premature given the missing data for critical security devices.

Refinement is needed to gather the full context of the day's events, specifically focusing on the missing lock/contact logs and any other transient faults.

CH-04-FP: 家长在玄关操作门锁

The kitchen cook surface was activated and left on for approximately 9.5 minutes while the kitchen light was turned off and no occupancy was detected in the kitchen, creating a potential unattended cooking fire risk.

Explanation: 1. **Hazard Trigger**: The `kitchen_cook_surface` was turned ON at 07:10:35 (C06). This is a primary fire hazard source.

Explanation: 2. **Vulnerable Context**: Shortly after activation (at 07:14:10), the `kitchen_light` was turned OFF. Crucially, there are no `kitchen_occupancy` logs between 07:10:35 and 07:20:00 indicating anyone was present in the kitchen to monitor the heat source.

Explanation: 3. **Absence of Mitigation**: No smoke or CO alarms were triggered during this period, and no manual intervention (like turning off the stove) is logged until the device state changes to OFF at 07:20:00. While the device did turn off, the lack of evidence confirming it was a manual action versus an automatic timer leaves the 'unattended' scenario as the most plausible explanation for the gap in supervision.

Explanation: 4. **Sensor Reliability**: Although the `kitchen_temp_sensor` had transient dropouts (`None` values), these do not constitute a device fault requiring immediate repair but rather highlight a lack of real-time thermal monitoring during the critical heating phase.

Explanation: 5. **Conclusion**: The sequence of activating a heat source, turning off visibility (light), and having no presence logs constitutes a classic 'unattended cooking' pattern. While no fire occurred, the safety condition was compromised.

C06: `kitchen_cook_surface` ON at 07:10:35, OFF at 07:20:00.

C06: `kitchen_light` OFF at 07:14:10 (while cook surface was still ON).

C06: No `kitchen_occupancy` events recorded between 07:10:35 and 07:20:00.

C06: No `smoke_co_alarm` triggers during the event window.

Verify if the cook surface has an automatic timer feature that explains the 07:20:00 shutoff.

Review camera footage (if available) for the kitchen area between 07:10 and 07:20 to confirm human presence/absence.

Ensure smoke detectors are functional and tested, as they did not trigger despite the potential hazard.

Cooking activity without immediate alarm activation (potential fire risk)

Door lock state transitions (security verification)

Occupancy patterns indicating presence during high-risk activities

Temperature trends in kitchen vs other rooms

C18 provides context for another manual lock operation at the entrance, helping to establish security behavior patterns.

C27 shows the end-of-day routine including locking the door and turning off lights/AC, serving as a baseline for 'safe' state closure and verifying if the system properly secures the home at night.

Normal morning routine with brief cooking and transient sensor dropout. The kitchen cook surface was used for a short duration (approx. 9.5 minutes) while the household was active elsewhere, and the temperature sensor experienced a momentary network glitch that resolved immediately.

C06: `kitchen_cook_surface` turned on at 07:10:35 and off at 07:20:00, a duration consistent with preparing a quick meal or boiling water.

C06: No smoke alarm or fire hazard events were triggered during or after the cooking event.

C06: `kitchen_temp_sensor` returned `None` at 07:11:05 but resumed normal readings (25.18 C) by 07:15:00, indicating a transient data loss rather than permanent failure.

C05/C06: Occupancy sensors in other rooms (kids, master bedroom) show continuous activity, suggesting someone is present in the home to supervise if needed, even if not explicitly logged in the kitchen at that exact second.

C06: Front door lock operation at 07:14:35-07:14:46 shows a standard manual unlock followed by an auto-lock, consistent with leaving the house briefly or securing it upon exit.

Relies on the assumption that 'someone is home' equates to 'supervising the kitchen', which is not guaranteed by occupancy logs in other rooms.

Does not fully explain why the kitchen light was turned off (07:14:10) shortly after the cook surface was turned on, potentially reducing visibility or awareness of the cooking process.

Unattended Cooking Risk. The cook surface was activated while the kitchen appeared unoccupied (no direct occupancy log in the immediate pre-cooking window), and the kitchen light was turned off shortly after activation, creating a scenario where a fire hazard could go unnoticed.

C05: The last recorded `kitchen_occupancy` event prior to the cooking start time (07:10:35) is missing from the provided chunks; the last known state in C05 (07:10:00) does not include a kitchen occupancy update, and C06 starts with no kitchen occupancy log until later.

C06: `kitchen_light` turned ON at 07:10:05 but OFF at 07:14:10, only ~3.5 minutes after the cook surface was turned ON (07:10:35). This suggests the user may have left the kitchen or lost interest/attention shortly after starting the heat source.

C06: `kitchen_temp_sensor` returns `None` at 07:11:05, right as the cooking begins, removing a key safety monitoring signal during the critical initial phase of heating.

C06: No evidence of user return to the kitchen (e.g., new occupancy logs, light toggles, or device interactions) between 07:14:10 and 07:20:00 when the cook surface was finally turned off.

The absence of a specific `kitchen_occupancy` log does not definitively prove the room was empty; it may be a logging gap or blind spot, especially since other rooms show activity.

The cook surface was eventually turned off, preventing escalation to a full fire, though the risk period existed.

The supervisor feedback notes that inferring 'unattended' solely from missing occupancy logs is weak without corroborating evidence like a long duration or explicit 'away' status.

Transient Sensor Malfunction / Data Integrity Issue. The `kitchen_temp_sensor` exhibited intermittent failures (`None` values) coinciding with high-activity periods, raising concerns about the reliability of environmental monitoring.

C06: `kitchen_temp_sensor` reports `None` at 07:11:05 and again at 07:21:00.

C06: These dropouts occur during active household operations (cooking, lighting changes), suggesting potential interference or instability under load.

C06: The recovery is immediate (next reading is valid), which typically rules out permanent hardware failure but points to connectivity or software glitches.

The faults are isolated and self-resolving, lacking the persistence required for a definitive `sensor_malfunction` classification per the guidelines.

No explicit fault codes or alarms were generated by the device itself.

The sequence in C06: Cook Surface ON (07:10:35) -> Kitchen Light OFF (07:14:10) -> No Kitchen Occupancy Logs -> Cook Surface OFF (07:20:00). This pattern strongly suggests the user left the kitchen area while the heat source was active.

The simultaneous `None` value from the kitchen temp sensor at 07:11:05 removes real-time thermal monitoring during the most dangerous phase of cooking startup.

The lack of any `smoke_co_alarm` trigger despite the potential for unattended heating indicates either good luck or a delay in detection.

Direct confirmation of user location via mobile presence or other non-room-specific sensors to verify if anyone was actually in the kitchen during the cooking window.

Logs for `kitchen_occupancy` specifically between 07:05:00 and 07:15:00 to confirm if the sensor simply missed updates or if the room was truly empty.

Details on whether the `kitchen_cook_surface` has an automatic timer/shutoff feature that might have triggered the turn-off at 07:20:00, rather than manual intervention.

Status of the `smoke_co_alarm` device health and recent test results to ensure it wasn't disabled or faulty.

Verify if the `kitchen_cook_surface` has an automatic timer/shutoff feature that triggered the turn-off at 07:20:00.

Check for any smoke or heat alarms in C06/C07 to confirm no fire event occurred despite unattended cooking risk.

Analyze C07 (07:50-08:35) to see if kitchen temperature trends indicate residual heat or if the device was fully cooled, confirming the end of the cooking event.

The investigator correctly identified a potential 'unattended cooking' risk based on the sequence in C06 (Cook Surface ON -> Light OFF -> No Occupancy).

However, the conclusion relies heavily on the absence of occupancy logs ('missing logs') and a single transient sensor dropout (`None`). Per protocol, inferring 'unattended' solely from missing logs is weak without corroborating evidence like a long duration or explicit 'away' status.

The investigator failed to utilize Chunk C07, which covers the period immediately following the cook surface turn-off. This chunk is critical to determine if the device turned off automatically (timer) or manually, and to check for any subsequent thermal events or alarm triggers that would clarify the safety outcome.

Without C07, we cannot distinguish between a user leaving the stove on (high risk) vs. a timed auto-shutoff (low risk/normal behavior). The current evidence is insufficient to definitively label this as a safety hazard rather than a procedural anomaly or normal operation with logging gaps.

Request refinement using C07 to close the loop on the cooking event's resolution.

The home is in a normal, secure state with standard daily routines. Cooking activity was brief and supervised, followed by proper shutdown. Security protocols (auto-lock) functioned correctly at key transition points.

C06: Kitchen cook surface turned on at 07:10:35 and off at 07:20:00 (approx. 10 mins). This is a typical duration for breakfast preparation.

C06: Front door lock operated manually to unlock (07:14:35) and then auto-locked (07:14:46) shortly after occupancy cleared the entrance area, indicating a 'leave' routine.

C27: End-of-day routine shows lights and AC turning off (22:49), followed by an auto-lock event (22:49:30) when the front door contact closed, securing the home for the night.

Temperatures across all rooms remain within a narrow, comfortable range (22-25 C), showing no signs of fire or HVAC failure.

Occupancy patterns show consistent presence in bedrooms and living areas during evening hours, suggesting normal family activity.

Does not fully account for the lack of explicit smoke alarm activation during cooking, though this may be due to sensor placement or sensitivity settings rather than absence of risk.

Potential unattended cooking or delayed safety response. The kitchen cook surface was activated while the kitchen itself showed no immediate occupancy signal in the provided logs, and no smoke/CO alarm events were recorded despite the heat source being active.

C06: `kitchen_cook_surface` turns ON at 07:10:35.

C06: At 07:10:00, `master_bathroom_occupancy` is occupied. At 07:11:00, `kids_room_occupancy` is occupied. There is no explicit `kitchen_occupancy` = 1 log entry immediately following the cook surface activation in the snippet, although `entrance_occupancy` is active later.

C06: The cook surface remains ON until 07:20:00. No `smoke_co_alarm` fault or trigger events are logged in any chunk.

C06: `kitchen_temp_sensor` reports `None` at 07:11:05 and 07:21:00, potentially indicating it was obscured by steam/heat or malfunctioning during the high-risk period, removing a key safety feedback loop.

Triage Output explicitly flags 'Cooking activity without immediate alarm activation' as a suspected pattern.

The 10-minute duration is relatively short and common for quick meals, reducing the likelihood of a catastrophic fire if someone was nearby but not detected by the specific sensor logging.

Absence of `kitchen_occupancy` logs might be a data sampling gap rather than true absence; other rooms show occupancy, implying people are home.

No actual fire or smoke was detected, so the risk remained theoretical/mitigated by chance or human intervention outside the sensor scope.

Sensor reliability issue in the kitchen. The temperature sensor intermittently reported `None` values during and immediately after cooking, which could indicate a temporary failure or environmental interference that compromises safety monitoring.

C06: `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None` at 07:11:05 (shortly after cook surface ON).

C06: `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None` at 07:21:00 (immediately after cook surface OFF).

This intermittent loss of data coincides with the highest thermal stress event in the day.

The sensor recovers immediately after the events (values return to ~25 C), so it is not a permanent stuck fault.

Intermittent `None` values can occur due to network latency or temporary sensor overload from steam, which is a transient condition rather than a persistent device health failure.

C06: `kitchen_cook_surface` OnOff transition (ON at 07:10:35, OFF at 07:20:00) combined with `kitchen_temp_sensor` returning `None` twice during this window.

C06: Lack of explicit `kitchen_occupancy` = 1 logs during the initial cooking phase, contrasting with `master_bathroom` and `kids_room` occupancy.

C27: Successful auto-lock sequence at 22:49:30 confirms security system functionality, making the cooking anomaly more isolated to the kitchen environment.

Logs for `smoke_co_alarm` status or triggers during the 07:10-07:20 window to confirm if alarms were silent or non-existent.

Continuous `kitchen_occupancy` logs to verify if someone was actually present in the kitchen during cooking.

Details on why `kitchen_temp_sensor` returned `None` (e.g., was it physically covered, or did it fail?).

C06: `kitchen_cook_surface` turned on at 07:10:35 and off at 07:20:00, a duration consistent with preparing a quick meal or boiling water.

C06: No smoke alarm or fire hazard events were triggered during or after the cooking event.

C06: `kitchen_temp_sensor` reports `None` at 07:11:05 and again at 07:21:00.

Verify `kitchen_occupancy` status in the immediate pre-cooking window (C05) to confirm if the kitchen was truly unoccupied or if the sensor simply wasn't logging.

Check for any `smoke_co_alarm` trigger events in C06-C07 that might have been missed or suppressed.

Investigate the cause of `kitchen_temp_sensor` returning `None` (transient network error vs. physical obstruction/failure) by checking adjacent timestamps in C05 and C07.

Confirm if the cook surface has an auto-shutoff feature or if the manual off at 07:20:00 was user-initiated.

The investigator correctly identified the cooking event and the sensor anomaly but relies heavily on the absence of `kitchen_occupancy` logs to infer 'unattended' risk. This is a weak inference because occupancy sensors often have blind spots or sampling gaps; other rooms show activity, implying presence in the house.

The `sensor_malfunction` hypothesis (A2) is flagged as high false-alarm risk because it rests on two isolated `None` values that immediately resolve to normal readings without any persistent fault indicators or alarms. This looks more like transient data dropout than a device health failure.

To determine if this is a genuine safety risk (unattended fire hazard) or a false alarm (normal brief cooking with sensor gap), we need to see the context immediately before the cook surface turned on (Chunk C05) to check for prior occupancy signals or user actions, and the context after (Chunk C07) to ensure no delayed alarms occurred.

Current evidence is insufficient to rule out normal behavior or confirm a safety breach.
