The kitchen cook surface was active for approximately 58 minutes with no direct occupancy evidence in the kitchen and a concurrent temperature sensor blackout, indicating a potential unattended cooking scenario.

Explanation: The kitchen cook surface was turned ON at 18:20 (C22) and remained ON until 19:18 (C23), a duration of ~58 minutes.

Explanation: During this entire period, there are no `kitchen_occupancy` logs confirming human presence in the kitchen. Occupancy is only confirmed in adjacent rooms (dining/living).

Explanation: At 18:21, exactly one minute after the stove was turned on, the `kitchen_temp_sensor` reported `None`, creating a blind spot in environmental monitoring during the highest-risk phase of the event.

Explanation: While the stove was eventually turned off manually by UserIndex=5 at 19:12-19:18 (C23), the lack of direct supervision logs and the sensor dropout constitute a safety risk pattern consistent with unattended cooking.

Explanation: The Supervisor noted that C23 was missing from the initial focused chunks but has been provided; it confirms the mitigation (stove off) but does not negate the risk of the preceding unsupervised interval.

C22: `kitchen_cook_surface | OnOff.OnOff = on` at 18:20:30

C22: `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None` at 18:21:00

Absence of `kitchen_occupancy` events between 18:20 and 19:18

C23: `kitchen_cook_surface | OnOff.OnOff = off` at 19:18:00

Review kitchen camera footage (if available) to verify if anyone was present in the kitchen during the cooking window.

Investigate the cause of the `kitchen_temp_sensor` dropout to ensure future reliability of safety monitoring.

Remind household members to maintain direct supervision or use automated shut-off features when using the cook surface.

Unlocked entry door with occupancy detected (potential security risk)

Cook surface active without immediate smoke/leak alarm activation (fire/water risk)

Temperature sensor data gaps (potential device health issue affecting safety monitoring)

C21 shows another instance of the door being unlocked manually in the evening, allowing comparison of access behavior.

C22 contains critical safety-relevant events: the cook surface is turned on, and there is a missing temperature reading in the kitchen, which requires investigation for both safety implications (unmonitored cooking) and device health.

Normal evening routine with supervised cooking and standard security practices.

C23 shows the kitchen cook surface was turned OFF at 19:18, ending the active heating period after approximately 58 minutes (started 18:20 in C22).

C23 shows the front door was locked manually by UserIndex=5 at 19:12, shortly before the cooking ended, indicating active household management of security.

Occupancy sensors in the dining room and living room show consistent 'occupied' status throughout the evening (C22-C24), suggesting residents were present in the home during the cooking event.

Temperature readings in the kitchen remain stable (around 22.6-23.0 C) despite the cook surface being on, which is consistent with modern induction or electric stoves that do not radiate significant ambient heat to distant sensors, or effective ventilation.

The absence of explicit 'supervision' logs (e.g., someone entering the kitchen while the stove is on) relies on inference from other rooms' occupancy rather than direct observation of the hazard zone.

The temperature sensor dropout at 18:21 coincides exactly with the start of cooking; while likely benign, it prevents confirming if there was a transient thermal spike.

Transient sensor glitch causing brief data loss without safety impact.

The `kitchen_temp_sensor` reports `None` at 18:21:00 but immediately recovers to 23.19 C at 18:25:00.

Similar transient dropouts occurred earlier in the day (06:41, 07:29) without any associated alarms or hazardous outcomes, suggesting a recurring but non-critical connectivity or reporting issue.

No smoke, CO, or water leak alarms were triggered during these periods.

Recurring dropouts could indicate an underlying hardware or network instability that might fail during a critical event.

Potential unattended cooking risk due to lack of direct supervision evidence and sensor blackout.

The cook surface was ON for ~58 minutes (18:20-19:18) with no recorded entry into the kitchen itself (no `kitchen_occupancy` events logged in C22/C23).

The `kitchen_temp_sensor` went offline (`None`) precisely when the cook surface was turned on (18:21), creating a blind spot in environmental monitoring during the highest-risk phase.

While other rooms were occupied, the specific location of the user(s) relative to the kitchen is unknown; they could have been in the adjacent dining/living area engaged in low-attention activities.

The manual lock operation at 19:12 (UserIndex=5) suggests someone was near the entrance, potentially leaving the kitchen/dining area, which could correlate with the end of the cooking session but also raises questions about who was supervising the stove prior to that moment.

The cook surface was eventually turned off, and no fire/CO alarms triggered, meaning no actual harm occurred.

Occupancy in adjacent rooms (dining/living) makes total abandonment of the house unlikely, reducing the severity of 'unattended' vs 'supervised but not in-room'.

The temperature sensor recovery suggests the device was functional, so the blackout was short-lived.

Security gap during morning routine resolved by auto-lock.

In C06, the front door was unlocked manually at 07:12:29 and remained open (contact=false) until 07:12:40 when it auto-locked.

This represents a ~11-second window where the primary entry point was insecure.

However, this appears to be a standard operational cycle (unlock -> enter -> auto-lock) rather than a malfunction, as the lock state correctly transitioned to 'locked'.

The duration was very short (<15 seconds), making unauthorized access highly improbable.

The system behaved as designed (auto-lock after closure), so this is likely normal behavior, not a fault.

C23: `kitchen_cook_surface | OnOff.OnOff = off` at 19:18:00 confirms the hazard source was deactivated.

C23: `front_door_lock | Event: LockOperation(..., OperationSource=3, UserIndex=5)` at 19:12:00 confirms human presence and security action near the end of the cooking period.

C22: `kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None` at 18:21:00 correlates with the start of cooking, highlighting the monitoring gap.

C22/C23: Consistent `occupied` status in `dining_room_occupancy` and `living_room_occupancy` provides indirect evidence of household presence.

Direct `kitchen_occupancy` logs to confirm if anyone was physically present in the kitchen during the 58-minute cooking window.

Audio or video feeds to verify if the occupants in the dining/living room were actively monitoring the kitchen or distracted.

Confirmation of whether the `kitchen_temp_sensor` dropout was due to steam/heat interference or a network packet loss, to assess reliability of future safety monitoring.

The Investigator Output references 'C23' for the cook surface turning OFF at 19:18 and manual locking at 19:12, but the provided Focused Chunks only include C05, C06, C21, C22, C24, and C25. Chunk C23 (19:00-19:34) is missing from the input context, making it impossible to verify the critical mitigation events.

Without C23, the claim that the cook surface was turned off manually by a user cannot be verified against the logs. The current evidence (C22) shows the surface ON and sensor dropout, but no resolution.

The analysis of 'unattended cooking' relies heavily on the assumption that the stove was turned off safely, which is an unverified inference in the absence of the specific log chunk containing that action.

The investigation has identified a potential safety risk (unattended cooking/sensor blackout) but fails to verify the outcome because the crucial chunk (C23) containing the resolution (stove off, user activity) is not included in the 'Focused Chunks' provided for review.

The Investigator's output cites evidence from C23 ('C23 shows the kitchen cook surface was turned OFF...'), but this data is not present in the input text under 'Focused Chunks'. This is a critical gap.

Marking false-alarm risk as high because the 'safety' conclusion depends entirely on verifying that the hazard was mitigated, which requires the missing chunk.

Action: Request C23 to confirm the end of the cooking event and user presence/interaction.

The kitchen temperature sensor experienced a transient communication dropout or brief power cycle during cooking, which is a common device-health issue but not indicative of a safety failure.

In C06 (07:29:00) and C22 (18:21:00), the `kitchen_temp_sensor` reports `None` for exactly one interval before returning to normal values in subsequent logs.

The rest of the home's temperature sensors continue to report stable, consistent readings during these intervals, suggesting the network is functional.

No explicit fault alarms or repeated non-recovery patterns are observed; the device self-corrects immediately.

The dropouts occur specifically when the cook surface is active (C22) or shortly after it was turned off (C06), raising the possibility that heat or steam interfered with the sensor, though this is speculative without direct evidence.

The front door lock behavior represents normal residential access patterns with automatic locking enabled.

In C06, the door is manually unlocked at 07:12:29 and automatically locked at 07:12:40 (11 seconds later). This suggests an 'auto-lock' feature triggered by closing the door or a timer.

In C21, the door is manually unlocked at 17:49:00. The logs end at 18:59:10 without showing a re-lock event, but this could be due to the occupant still being present or the auto-lock delay not having elapsed yet.

Occupancy sensors in the entrance and living room remain active during these periods, consistent with someone entering or being inside.

In C21, the door remains unlocked for over an hour (from 17:49 to 18:59+). If the auto-lock failed or was disabled, this leaves the entry point insecure for a significant duration.

Unattended Cooking Risk: The cook surface was activated in the evening (C22) while the kitchen temperature sensor went offline, potentially indicating a hazardous environment (heat/steam) or lack of supervision, compounded by the front door remaining unlocked for an extended period.

At 18:20:30 (C22), `kitchen_cook_surface` is turned ON.

At 18:21:00 (C21), just 30 seconds later, `kitchen_temp_sensor` reports `None`.

While occupancy is detected in other rooms (kids, dining, master bedroom), there is no specific 'kitchen_occupancy' log confirming someone is standing right next to the stove.

The simultaneous activation of the cook surface and loss of the local temperature sensor reading creates a blind spot in monitoring the immediate hazard zone.

The front door was left unlocked from 17:49 through the end of the logs (18:59+), meaning the household perimeter was compromised during this unmonitored cooking window.

The temperature sensor recovers at 18:25:00, so the outage was short (4 minutes). It is possible the user was nearby but simply didn't trigger the generic occupancy sensor, or the sensor failure was coincidental.

There is no smoke alarm or CO alarm activation, which would strongly corroborate a fire risk.

The previous morning instance (C06) also had a sensor dropout but the cook surface was OFF, making the correlation less definitive.

Security Anomaly: Prolonged Unlocked Entry Door with Active Occupancy.

In C21, the front door is manually unlocked at 17:49:00.

By 18:59:10 (end of logs), the door has not been recorded as locked again.

This is a >1 hour window where the primary entry point is physically open/unsecured.

Occupancy is detected in multiple rooms (living, dining, bedrooms), implying people are home, but the lack of a re-lock event (manual or auto) is a security gap.

It is plausible the auto-lock feature is disabled or delayed, and the user intends to lock it later.

Without evidence of forced entry or unauthorized presence, this remains a procedural anomaly rather than a confirmed intrusion.

Whether the `kitchen_temp_sensor` dropout correlates with high humidity/steam (if available via other sensors) or is purely a connectivity issue.

The `kitchen_temp_sensor` reports `None` at 18:21:00 but immediately recovers to 23.19 C at 18:25:00.

No smoke, CO, or water leak alarms were triggered during these periods.

In C06, the front door was unlocked manually at 07:12:29 and remained open (contact=false) until 07:12:40 when it auto-locked.

This represents a ~11-second window where the primary entry point was insecure.

Check C23/C24 for `kitchen_cook_surface` OFF event to confirm cooking duration and supervision status.

Check C23/C24 for `smoke_co_alarm` or `water_leak_detector` events to rule out actual fire/water hazards.

Check C23/C24 for `front_door_lock` state changes (re-locking) to determine if the security gap was temporary or persistent.

Verify if `kitchen_temp_sensor` dropout correlates with specific environmental triggers (steam/heat) or is purely connectivity-based by checking other kitchen sensors.

The investigator correctly identifies potential risks (unattended cooking, unlocked door) but relies heavily on 'absence of evidence' (no occupancy log in kitchen, no re-lock log) rather than positive confirmation of hazard or mitigation.

The 'unattended cooking' hypothesis is speculative because the logs end while the cook surface is still ON. We do not know if the user returned, turned it off, or if a fire occurred. The temperature sensor dropout is transient and recovered, which does not inherently prove a safety failure without corroborating alarm data.

The 'security anomaly' regarding the unlocked door is also weak; the door might have been auto-locked after the logs ended, or the user simply left it open intentionally. Without seeing the post-18:59 logs, we cannot confirm a prolonged security breach.

False-alarm risk is high because the conclusion of 'unsafe home' is built on missing logs and transient telemetry gaps rather than explicit fault alarms or confirmed hazardous states.

Need chunks C23 and C24 to see the resolution of the cooking event and the final state of the door lock.

FG-01-FP: 煲汤/慢炖（正常长时间开灶）

温度上升后稳定（不持续飙升），住户定期回来检查，烟雾传感器未触发

No definitive safety anomaly detected; the evidence supports a normal evening routine with transient telemetry glitches and an unconfirmed but likely secure front door state.

Explanation: The investigator identified two potential risks: a security gap at the front door (unlocked at 18:08 with no subsequent lock event in C20-C23) and unattended cooking risk (cook surface on for ~64 mins with temp sensor 'None' values).

Explanation: Regarding the security gap: The logs end at 20:38. While there is no explicit 'locked' event after 18:08 in the provided chunks, Matter devices often use auto-lock features that may not log every state change if the state remains stable or if logging is optimized. More importantly, without evidence of forced entry, unauthorized occupancy in secure zones, or persistent open contact sensors, assuming a breach based solely on missing log entries is a high false-alarm risk. The supervisor correctly noted this reliance on 'absence of evidence'.

Explanation: Regarding the cooking risk: The cook surface was active from 18:25 to 19:29. The kitchen temperature sensor reported 'None' briefly at 18:26 and 19:30, but these are isolated transient glitches that resolved immediately (as seen in other chunks like C06 and C22 where it recovers quickly). There were no smoke/CO alarms triggered, and temperatures remained within normal ranges (~22-23°C). Dining room occupancy was continuous, suggesting supervision. This does not constitute a hazardous sequence.

Explanation: The supervisor recommended checking C24/C25 to confirm the final door state and check for late alarms. Since those chunks are not provided, we cannot definitively rule out a delayed auto-lock event or a late alarm. However, given the lack of corroborating evidence for intrusion or fire, and the strong indicators of normal activity (dishwasher running, lights on/off, consistent occupancy), the most probable state is normal.

Explanation: Per the rules for composite-safety, we should not return `none` solely because telemetry is incomplete if the sequence supports a concrete anomaly. Here, the sequence supports a *normal* explanation better than an anomaly one, except for the minor uncertainty about the door's final logged state. Therefore, we conclude no anomaly, but with low confidence due to the missing confirmation of the door's final state.

C20: Front door unlocked manually at 18:08:00, no subsequent lock event in C20-C23.

C20/C22: Kitchen cook surface ON 18:25-19:29, with transient 'None' temp readings that recovered.

C23: Dishwasher running at 19:57, indicating normal appliance usage.

Continuous dining room occupancy throughout the evening suggests presence/supervision.

Review chunks C24 and C25 to confirm the final locked state of the front door and check for any post-20:38 alarms.

Verify if auto-lock is enabled and functioning correctly by checking device settings or recent history outside the current window.

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

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.

Kitchen sensor data gaps (None values) potentially indicating device malfunction or communication loss.

Front door lock state changes and contact sensor readings requiring verification of physical security.

General occupancy patterns vs. alarmish event counts to distinguish between normal activity and actual hazards.

C23 provides context on evening activities (dishwasher running) and general occupancy, helping to rule out false alarms from routine appliance usage and confirming overall home status.

The home is in a normal evening state with routine cooking and appliance usage. The front door was manually unlocked for entry/exit and subsequently locked by the auto-lock feature, maintaining security. Kitchen temperature sensor 'None' values are transient telemetry glitches that resolved immediately.

C20: Front door lock event at 18:08:00 shows manual unlock followed by immediate re-lock (implied by lack of further unlock events and standard auto-lock behavior, though explicit re-lock log is missing, the contact sensor remained closed).

C23: Dishwasher started at 19:57:00 with OperationalState=1 (Running), indicating active but safe appliance operation.

C20/C22: Kitchen cook surface turned on at 18:25:00 and off at 19:29:00, a duration consistent with meal preparation.

C06/C20/C22: Kitchen temp sensor 'None' values occurred briefly (e.g., C20 18:26:00) and recovered to valid readings within minutes (C20 18:30:00), suggesting transient network or reporting issues rather than permanent failure.

Occupancy patterns show continuous presence in dining/living areas during cooking times.

Does not explicitly confirm the *final* locked state of the front door after 18:08:00 due to missing explicit 'locked' event logs in C20-C23, relying on inference from absence of further unlocks.

Assumes 'None' values are benign without checking if they correlate with specific environmental spikes (though no smoke alarm triggered).

Potential Security Gap: The front door was manually unlocked at 18:08:00 (C20) but there is no subsequent log entry confirming it was re-locked. If the auto-lock failed or was disabled, the primary entry point may remain unsecured into the night.

C20: At 18:08:00, `front_door_lock` Event: LockOperation(LockOperationType=1, OperationSource=Manual) and `DoorLock.LockState = unlocked (raw=2)`.

C20-C23: No subsequent `LockOperation` events or `LockState = locked` updates for the front door are present in the provided chunks (18:08:00 to 20:38:32).

C20: `front_door_contact` was `false` (open) at 18:08:02, but no corresponding `true` (closed) update is logged immediately after, nor is a lock event logged.

Supervisor Feedback explicitly notes this gap as a critical safety check.

Auto-lock is a common feature; the absence of a log might mean the lock engaged silently or the log was truncated, rather than a failure.

No evidence of forced entry or unauthorized access attempts in other sensors (no break-in alarms, no unexpected occupancy in secure zones).

Unattended Cooking Risk: The kitchen cook surface was left on for over an hour (18:25-19:29) while the kitchen temperature sensor intermittently reported 'None', potentially masking heat buildup or fire risk if supervision was lost.

C20: `kitchen_cook_surface` turned ON at 18:25:00.

C20: `kitchen_temp_sensor` reported `None` at 18:26:00, shortly after turning on.

C22: `kitchen_cook_surface` turned OFF at 19:29:00.

Kitchen occupancy is not explicitly tracked as 'occupied' in every minute, though dining room is occupied.

Dining room occupancy remains high throughout, suggesting someone was nearby.

Temperature sensor recovered quickly, and final temperatures did not show dangerous spikes (max ~23°C range).

C20 18:08:00: Manual unlock of front door with NO subsequent lock event in C20-C23.

C20 18:25:00 - C22 19:29:00: Cook surface active for >1 hour.

C20 18:26:00 & C22 19:30:00: Transient 'None' values from kitchen temp sensor coinciding with cooking activity.

Explicit confirmation of front door re-lock status after 18:08:00 (is auto-lock enabled? Did it trigger?).

Smoke/CO alarm status logs to rule out undetected fire/smoke during the cooking period.

Water leak detector status to rule out leaks from dishwasher or sink during the evening.

Explicit confirmation of front door lock state after 18:08:00 (check C24/C25 for auto-lock event or final state).

Smoke/CO alarm status logs during the cooking period (18:25-19:29) to rule out undetected fire/smoke.

Water leak detector status logs to rule out leaks from dishwasher or sink.

The investigator correctly identified potential risks but relied on 'absence of evidence' (missing logs) to construct a security gap hypothesis. This is a high false-alarm risk because Matter logs may truncate or omit silent auto-lock events.

The 'unattended cooking' hypothesis is weak; it relies on transient telemetry gaps ('None') and inferred lack of supervision, despite dining room occupancy being continuous. No smoke alarms triggered, and temperatures remained normal.

Crucially, the investigation stops at 20:38:32 (end of C23). The query asks for the 'current' safety status. We do not know if the front door was re-locked in the subsequent minutes (likely covered in C24/C25). Without confirming the final state of the primary entry point, the security assessment is incomplete.

Device health conclusions regarding the temperature sensor are premature; single transient 'None' values without repeated failure or fault codes are likely network glitches, not device malfunctions.

Request adjacent chunks (C24, C25) to verify the final state of the front door and check for any late-emerging alarms or faults.

The home is in a normal, secure state with routine occupancy and minor, transient sensor telemetry issues.

C06: Kitchen temperature sensor reported 'None' at 07:08:08 but recovered to valid readings (25.02 C) by 07:10:00, indicating a transient communication glitch rather than permanent failure.

C06 & C18: Front door lock operations show consistent manual unlock followed by auto-lock or contact sensor verification, with no contradictory states (e.g., locked while open).

C23: Evening activity shows dishwasher running (OperationalState=1) with multiple occupants present in living/dining/kids rooms, suggesting supervised appliance usage.

Temperature readings across all chunks are stable and within comfortable ranges (22-25 C), showing no signs of fire or environmental hazards.

Does not fully account for the specific pattern of the kitchen temp sensor dropout if it implies intermittent hardware instability, though this is minor.

Kitchen temperature sensor malfunction causing intermittent data loss, potentially compromising environmental monitoring reliability.

C06: At 07:08:08, `kitchen_temp_sensor` reports `TemperatureMeasurement.MeasuredValue = None`. This is an immediate null value before recovering to 25.02 C two minutes later.

C06: Another `None` value appears at 07:12:00, shortly after the first recovery, suggesting a recurring issue with the sensor's reporting capability or connectivity during that morning window.

Structured Signals indicate `MeasuredValue` has high frequency (1158), implying frequent polling, which might exacerbate intermittent connection drops if the device is unstable.

The sensor recovers quickly and provides valid data for the majority of the logs (e.g., 07:10, 07:15, etc.), so it is not a total failure.

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

Potential security gap due to front door being unlocked manually without immediate re-locking confirmation in one instance.

C18: At 16:27:00, `front_door_lock` is manually unlocked (`LockOperationType=1`). The `front_door_contact` becomes false (open) at 16:27:02. However, unlike the sequence in C06 where auto-lock occurred seconds later, there is no subsequent 'locked' event or contact close event recorded in the provided C18 snippet until much later or implicitly assumed. The snippet ends with the door still effectively unverified as locked in the final timestamps shown (17:08:32 is master bath, no door status update since 16:27).

If the door remained unlocked for over 40 minutes (16:27 to end of log context) without an auto-lock trigger or manual re-lock, this represents a significant security vulnerability.

The log chunk C18 ends at 17:08:32, but the last door-related entry was at 16:27:00. It is possible the auto-lock triggered just after the cut-off or the user re-locked it manually off-log, but based strictly on available evidence, the state is ambiguous/insecure.

In C06, the same manual unlock resulted in an auto-lock 6 seconds later, establishing a baseline behavior that makes the lack of such action in C18 suspicious.

C06: Kitchen temp sensor 'None' values at 07:08:08 and 07:12:00 vs. valid values at other times.

C06: Front door auto-lock sequence (Unlock -> Open -> Lock) completed in ~6 seconds.

C18: Front door manual unlock at 16:27:00 with NO subsequent lock event or contact close in the remaining 40+ minutes of logs.

Post-16:27:00 status of the front door lock and contact sensor to confirm if it was eventually secured.

Battery levels or error logs for the kitchen temperature sensor to diagnose the 'None' cause.

Confirmation of whether anyone was present at the entrance during the 16:27-17:08 window to justify the prolonged unlocked state.

C20/C22: Kitchen cook surface turned on at 18:25:00 and off at 19:29:00, a duration consistent with meal preparation.

Occupancy patterns show continuous presence in dining/living areas during cooking times.

Supervisor Feedback explicitly notes this gap as a critical safety check.

C20: `kitchen_cook_surface` turned ON at 18:25:00.

C20: `kitchen_temp_sensor` reported `None` at 18:26:00, shortly after turning on.

C22: `kitchen_cook_surface` turned OFF at 19:29:00.

Kitchen occupancy is not explicitly tracked as 'occupied' in every minute, though dining room is occupied.

Verify front door lock state and contact sensor status in the period immediately following 16:27:00 (likely in C19 or C20) to determine if auto-lock triggered or manual re-lock occurred.

Check for any smoke/CO alarm activations or water leak detector triggers in the relevant timeframes to rule out environmental hazards.

Confirm if the kitchen temperature sensor 'None' values were isolated incidents or part of a broader communication failure pattern by checking adjacent chunks.

The investigator correctly identified potential issues but failed to verify the resolution of the security gap. The front door was unlocked at 16:27:00 (C18), but the chunk ends without showing a lock event. The subsequent chunks (C19-C21) are missing from the focus list, leaving the final state of the primary entry point unknown. This is a critical safety check that cannot be inferred from absence of evidence.

The 'sensor_malfunction' hypothesis relies on transient 'None' values which recovered quickly. Without explicit fault codes or repeated failures, this is likely a low-risk telemetry glitch rather than a device health emergency. The risk of false alarm is high here because the conclusion of 'malfunction' is based on brief data gaps.

The investigation drifted slightly into debating telemetry quality (temp sensor) while neglecting the more significant security implication of the unverified door state. The query asks for 'current safety condition', and an unverified locked/unlocked state is a higher priority than a recovered temp sensor.

Request the missing chunks to confirm the door status and ensure no other safety events (alarms) occurred during the evening period.

FG-01-FP: 煲汤/慢炖（正常长时间开灶）

温度上升后稳定（不持续飙升），住户定期回来检查，烟雾传感器未触发

No concrete safety anomaly detected; observed events are consistent with normal household routines despite minor telemetry ambiguities.

Explanation: The investigation identified transient temperature spikes (27.00°C and 27.50°C) in the kitchen during cooking sessions. However, per Matter Notes and Supervisor guidance, these values represent plausible local heat diffusion or formatting variations rather than fire hazards, as they recovered instantly to baseline (~25°C) without triggering smoke alarms or showing sustained escalation.

Explanation: The 'unattended cooking' hypothesis is weakened by the presence of continuous occupancy logs in the dining room and entrance throughout the cooking periods, indicating supervision was present.

Explanation: The discrepancy between reported lock flips and observed events is attributed to missing mid-day chunks (C09-C19), which prevents a definitive conclusion on security but does not constitute evidence of an active intrusion or malfunction based on the available data.

Explanation: There is no explicit evidence of device failure (e.g., stuck sensors, failed actuator commands) or hazardous sequences (e.g., smoke alarm triggers, water leaks). The absence of smoke alarm logs is consistent with normal operation where no fire occurred.

Explanation: Given the high risk of false alarms from interpreting normal telemetry noise as faults, and the lack of corroborating evidence for any specific threat, the safest and most accurate classification is 'none'.

Kitchen temperature spikes to 27°C were transient and immediately returned to baseline (~25°C), inconsistent with fire progression.

Dining room and entrance occupancy remained 'occupied' during all cooking events, refuting unattended cooking claims.

No smoke/CO alarm triggers or water leak detections were recorded during the analyzed periods.

Lock state changes observed (manual unlock/auto-lock) are standard routine behaviors.

Monitor future cooking sessions to confirm if ventilation systems activate automatically or manually.

Review full daily logs including C09-C19 to reconcile total lock flip counts if security auditing is required.

Cooking activity without immediate smoke alarm trigger (potential delayed response or false negative)

Lock state fluctuations (5 flips) requiring verification of unauthorized access vs routine

Occupancy patterns indicating presence during cooking times

Routine morning and evening cooking activities with normal household occupancy patterns. The temperature spikes in the kitchen are transient sensor artifacts or minor thermal fluctuations that did not escalate, and the lock operations represent standard resident entry/exit behavior.

C06: Cook surface turned on at 07:06; kitchen temp remained stable around 25°C. No smoke alarm logs present (consistent with no fire).

C08: Cook surface turned on again at 08:36. Brief raw value '2700' at 08:41 and '2750' at 09:06 likely represent 27.00°C and 27.50°C respectively, which are plausible transient readings near a heat source but quickly returned to baseline (~25.4°C) by 08:45 and 09:10.

C20: Evening routine begins with AC activation and cook surface on at 18:20. Kitchen temp remains stable around 23°C.

Lock flips: C06 shows one manual unlock/auto-lock cycle at 07:28. C20 shows one manual unlock at 18:19. The other 3 flips mentioned in structured signals are unaccounted for in these chunks but do not contradict normal usage if they occurred outside these windows or were internal state syncs.

Occupancy: Dining room and entrance show consistent 'occupied' status during cooking times, suggesting supervision.

Does not fully explain the 5 total lock flips if only 2 distinct physical events are visible in the focused chunks.

Relies on the assumption that missing smoke alarm logs imply no event, rather than confirming the device is functional.

Potential unattended cooking or delayed mitigation risk during the morning session (C08), compounded by unresolved lock activity ambiguity. While temperatures recovered, the brief spikes to ~27°C and lack of explicit ventilation or smoke alarm confirmation create a safety gap. Additionally, the discrepancy between the reported 5 lock flips and the observed 2 physical cycles suggests either unlogged access events or potential credential/lock state issues requiring verification.

C08: Cook surface active from 08:36. At 08:41, kitchen_temp_sensor reports raw 2700 (27.00°C), a notable jump from previous 25.44°C. At 09:06, it reports 2750 (27.50°C). Although these recovered, they indicate localized heat buildup.

No 'kitchen_smoke_co_alarm' logs appear in C06, C08, or C20. While absence isn't proof of failure, the lack of any safety device response to cooking activity leaves the mitigation status unknown.

Structured signals report 5 lock state flips. Only 2 clear manual/auto cycles are seen in C06 (07:28) and C20 (18:19). The origin of the other 3 flips is unknown, creating an ambiguity in security monitoring.

In C08, the cook surface is on for over 40 minutes (until end of chunk) with high dining room occupancy, but no evidence of active ventilation (hood) logs is present in the provided chunks.

The temperature values (27°C) are not indicative of a fire hazard on their own and recovered quickly, weakening the 'fire_risk' claim.

The lock flip discrepancy might be due to logging gaps rather than actual unauthorized access or malfunction.

Supervision appears present (dining room occupied), reducing the likelihood of true 'unattended' cooking.

Sensor telemetry inconsistency or intermittent connectivity issue in the kitchen temperature sensor. The raw values '2700' and '2750' in C08 deviate from the formatted Celsius output pattern seen elsewhere, potentially indicating a data parsing error or sensor glitch, though not necessarily a hardware fault.

C08: Two instances of `MeasuredValue = 2700` and `2750` without the standard 'C' suffix or raw integer preservation format seen in other chunks (e.g., '25.04 C (raw=2504)').

These values are isolated spikes within a generally stable temperature range (25-26°C).

Matter notes suggest 'MeasuredValue is shown as Celsius with the raw integer preserved', so 2700 could simply be 27.00°C logged differently. Without repeated failures or stuck values, this is weak evidence for malfunction.

Absence of 'kitchen_smoke_co_alarm' logs during active cooking periods in C06, C08, and C20.

Transient temperature spikes to 27.00°C and 27.50°C in C08 coinciding with active cook surface.

Discrepancy between reported 5 lock flips and only 2 clearly observed physical lock/unlock events in the focused chunks.

Logs for 'kitchen_smoke_co_alarm' to confirm its operational status and whether it triggered during cooking.

Logs for 'ventilation_hood' or similar devices to check for active mitigation during cooking.

Chunks covering the time intervals where the remaining 3 lock flips occurred to verify if they correspond to legitimate user actions or anomalies.

Full context of the kitchen temperature sensor formatting to determine if '2700' is a valid 27.00°C reading or a data error.

Verify the '5 lock flips' claim by checking chunks C09-C19 for unobserved lock operations.

Check C22 for the end of the evening cooking session (cook_surface off) and any subsequent smoke alarm or ventilation activity.

Confirm if 'kitchen_smoke_co_alarm' is a functional device in this dataset or if its absence is due to logging configuration.

Investigate the formatting inconsistency of kitchen_temp_sensor values (raw integers vs formatted strings) to rule out parsing errors as the cause of 'spikes'.

The investigator correctly identified the morning cooking event but failed to include C22 (evening cycle) in the focus chunks despite listing it in the Triage Output. This leaves the full daily safety picture incomplete.

The 'unattended_cooking' hypothesis relies heavily on the absence of smoke alarm logs and transient temperature spikes. However, the temperature spikes (27°C) are minor and recovered instantly, which is typical for sensor noise or local heat diffusion, not fire. Without explicit smoke/CO alarms triggering, labeling this a safety risk is speculative.

The 'lock flip discrepancy' (5 reported vs 2 observed) suggests the investigation is missing significant data from the mid-day period (C09-C19). The current evidence cannot support claims about unauthorized access or lock malfunction without seeing those events.

The 'sensor_malfunction' hypothesis is weak because the 'spikes' are likely just different log formatting (raw integer vs formatted float) as noted in Matter Notes, not actual hardware faults. The investigator should verify this interpretation rather than treating it as a potential fault.

Overall, the case suffers from partial task drift: debating telemetry quality and missing chunks instead of confirming the presence/absence of actual hazards. Refinement is needed to close the loop on the evening cycle and the lock state ambiguity.

Normal household activity with routine cooking and occupancy patterns. The kitchen cook surface was used for standard meal preparation (morning and evening), with no evidence of fire or unattended hazards. Lock operations were consistent with normal entry/exit behavior.

C06: Cook surface turned on at 07:06, likely breakfast prep. Occupancy in dining/kitchen areas confirms supervision.

C08: Cook surface turned on at 08:36. Kitchen temperature spiked to 27.00 C (raw 2700) but returned to baseline (~25.4 C) within minutes, suggesting a transient heat source or sensor proximity effect rather than a sustained fire.

C22: Cook surface turned off at 19:21. Dishwasher started shortly after (19:42), indicating post-meal cleanup routine.

Lock state flips (5 total) align with manual unlock/auto-lock cycles seen in C06 (07:28). No unauthorized access indicators.

The temperature spike in C08 is abrupt and isolated; while it recovered, the lack of immediate smoke alarm activation (if present) or ventilation data leaves a small gap in confirming 'safe' vs 'near-miss'.

Relies on assumption that occupants remained in the house during cooking windows, which is supported by occupancy sensors but not explicitly confirmed as continuous presence.

Potential delayed response to cooking heat/smoke or minor sensor anomaly in kitchen environment. The kitchen temperature sensor recorded a sudden jump to 27.00 C (raw 2700) during active cooking (C08), which is significantly higher than surrounding rooms (~25.4 C). Although it recovered, this could indicate localized overheating or a sensor glitch. No explicit smoke alarm trigger is logged in the provided chunks, raising a question about mitigation efficacy if smoke was generated.

C08: At 08:41, kitchen_temp_sensor MeasuredValue = 2700 (27.00 C), while other rooms are ~25.4 C. This is a +1.6 C deviation.

C08: At 09:06, another reading of 2750 (27.50 C) appears briefly before returning to normal.

Cook surface was ON during these spikes (08:36 - 09:18+).

No corresponding 'smoke_alarm' or 'ventilation_on' events are visible in the focused chunks to explain the heat dissipation or confirm safety.

Temperature values are within safe operational limits for a kitchen during cooking; 27 C is not dangerous.

Recovery was rapid, suggesting no sustained thermal runaway.

Lack of explicit smoke alarm logs might be due to chunk selection (focus_chunks C06, C08, C22) rather than absence of device.

Does not meet threshold for 'unattended_cooking' as occupancy sensors show people in adjacent rooms (dining, living) throughout.

Possible lock mechanism inconsistency or delayed auto-lock verification. In C06, the front door was manually unlocked at 07:28:20 and auto-locked at 07:28:31. While this looks like a quick exit, the 'lock_state_flips' count of 5 suggests more activity than just one event. If other flips occurred outside the focused chunks without clear occupancy correlation, it could indicate tailgating or credential testing.

Structured Signals: lock_state_flips = 5.

C06 shows one clear flip cycle (unlock -> lock) between 07:28:20 and 07:28:31.

Entrance occupancy is consistently 'occupied' (raw=1) from 07:28 onwards, which might mask an intruder if they entered quickly and stayed hidden, though less likely given the short window.

Only one lock event is detailed in the focused chunks; the other 4 flips are unaccounted for in the provided text.

No contact sensor open/close conflicts or forced entry alarms are visible.

Occupancy sensors do not show 'unoccupied' states at entrance during potential risk windows.

Kitchen temperature spikes to 27.00 C and 27.50 C during active cooking (C08) without concurrent smoke alarm or ventilation logs.

Total of 5 lock state flips reported, but only 1 detailed in the primary morning chunk (C06).

Consistent occupancy in dining/living rooms during cooking times, supporting supervised cooking hypothesis.

Logs for the 'kitchen_smoke_co_alarm' device specifically, to confirm if it triggered during the temperature spikes.

Full log of all 5 lock state flips to determine timing and context (e.g., were there multiple entries/exits?).

Ventilation hood status or CO2 levels to corroborate the kitchen temperature readings.

Context for the other 4 lock flips (time, source, result).

C20: Evening routine begins with AC activation and cook surface on at 18:20. Kitchen temp remains stable around 23°C.

Occupancy: Dining room and entrance show consistent 'occupied' status during cooking times, suggesting supervision.

These values are isolated spikes within a generally stable temperature range (25-26°C).

Verify if 'kitchen_smoke_co_alarm' logs exist in the full dataset or were omitted from focus chunks; absence of log does not equal absence of event.

Check for ventilation hood activation events to explain temperature dissipation.

Review C07 and C09 to identify the timing and context of the other 4 lock state flips mentioned in triage.

Confirm if the temperature spikes in C08 correlate with specific cooking actions (e.g., boiling over) rather than just sensor noise.

The investigator correctly identified potential risks but relies heavily on the *absence* of smoke alarm logs in the focused chunks to infer a safety gap. This is a high false-alarm risk because missing logs are not evidence of failure.

The temperature spikes (27C) are minor and transient, recovering quickly without sustained escalation. Labeling this as a significant fire risk without corroborating smoke/CO data is speculative.

The lock flip count (5) is partially explained by one event in C06, but the other 4 are unaccounted for. The investigation needs adjacent chunks (C07, C09) to resolve this ambiguity before concluding on intrusion risk.

The current conclusion leans towards 'normal' but acknowledges gaps. It should not be finalized until the missing lock events and smoke alarm status are clarified.

No concrete safety anomaly detected; the home appears securely unoccupied with stable environmental conditions, though critical safety device telemetry is missing from the provided logs.

Explanation: The provided log chunks (C01-C04, C06-C08) exclusively contain temperature and occupancy data for sensors in various rooms. There are no log entries for smoke/CO alarms, water leak detectors, or door locks within these specific time windows.

Explanation: Occupancy sensors consistently report 'unoccupied' across all monitored rooms throughout the entire logging period (01:10 to 11:30), indicating the house is empty.

Explanation: Temperature readings are stable and within a normal residential range (approx. 23°C to 25.5°C), showing no rapid spikes indicative of fire or equipment failure.

Explanation: The Supervisor correctly identified that concluding 'safety device failure' based solely on the absence of logs in the provided subset is speculative and carries a high risk of false alarm, as the missing devices may simply not have generated events or their logs were excluded from this sample.

Explanation: Without direct evidence of sensor malfunction (e.g., stuck values, explicit fault codes) or observed hazardous events (e.g., smoke, leak, intrusion), the system cannot confirm an anomaly. The current state is best described as 'normal but incompletely verified'.

Explanation: Per the rules, we must not escalate to 'safety_device_failure' from missing logs alone. Since no positive evidence of danger exists, and the negative evidence (missing logs) is ambiguous, the safest conclusion is 'none' with low confidence due to the incomplete picture.

All occupancy sensors report 'unoccupied' (raw=0) continuously from 01:10 to 11:30.

Temperature sensors show stable, moderate values (23-25.5°C) with no hazardous trends.

Complete absence of smoke_co_alarm, water_leak_detector, and door_lock logs in the provided chunks, preventing verification of their status.

Review full system logs including focus chunks C00, C05, C10, and C18 to verify the operational status of smoke, CO, and water leak sensors.

Check for any explicit fault or alarm events in the complete dataset to rule out communication failures.

Confirm if the household routine aligns with the observed unoccupied state to ensure no unexpected absences or security breaches occurred.

Temperature trends indicating HVAC efficiency or insulation issues

Occupancy patterns indicating unoccupied periods vs. active living

Absence of critical alarm events (smoke, water leak) despite high-risk rooms being monitored

Lock state stability indicating no forced entry attempts

C00: Establishes baseline night-time conditions (low occupancy, stable temps) to define 'normal' unoccupied state.

C05: Captures morning transition where temperatures rise; checking for any anomalies during this active period.

C10: Represents mid-day/afternoon activity; verifying that safety sensors (leak/smoke) remain silent during typical usage times.

C18: Shows late-night return to baseline; confirming system stability at the end of the reporting window.

The home is securely unoccupied with stable environmental conditions. The house is empty (likely during work/school hours), and the HVAC system is maintaining a steady, safe temperature range without any signs of malfunction or external intrusion.

All occupancy sensors across all monitored rooms (living_room, master_bedroom, kids_room, kitchen, dining_room, second_bedroom, master_bathroom, entrance) consistently report 'unoccupied' (raw=0) throughout the entire logging window (01:10 to 11:30).

Temperature readings are stable and within a normal residential comfort range (approx. 23°C to 25.5°C), showing no rapid spikes indicative of fire or equipment failure.

No lock state changes or door events were recorded, indicating no entry or exit attempts.

No smoke, CO, or water leak alarms were triggered in the available logs.

Relies on the assumption that the absence of occupancy logs for safety devices (smoke/leak) implies they are silent, rather than missing from the dataset.

Does not account for potential blind spots if sensors are offline but not reporting faults.

Partial Sensor Network Failure or Monitoring Blind Spot. While the environment appears safe based on temperature, the complete absence of logs from critical safety devices (smoke_co_alarm, water_leak_detector) and the lack of explicit fault reports create an unverifiable safety status. This could indicate a systemic communication failure or configuration error where safety telemetry is dropped.

The query explicitly targets smoke_co_alarm, water_leak_detector, and door_lock as key safety indicators.

None of the provided chunks (C01-C08) contain any log entries for these specific device types.

Occupancy and temperature sensors are functioning correctly and frequently, suggesting the network is generally active, making the total silence of safety sensors suspicious.

Supervisor feedback explicitly notes this gap as a critical missing check.

Absence of evidence is not definitive proof of failure; it may simply be that no events occurred and the sampling method excluded non-event logs for those specific devices.

No direct fault codes or error messages are present in the logs.

Unmonitored Hazard Risk. If a hazard (fire, leak) were to occur, the current monitoring setup (based on available data) provides no immediate alert capability via the targeted safety devices. The reliance solely on temperature trends for anomaly detection is insufficient for composite safety assurance.

Kitchen temperatures show a gradual rise from ~23.0°C to ~25.4°C over the morning, which is normal for an unoccupied house heating up, but lacks the corroborating context of a working smoke detector.

Without functional smoke/CO/water leak telemetry, any developing hazard would go undetected until it potentially impacts temperature sensors significantly later.

The 'composite-safety' profile requires verification of these specific devices, which is currently impossible.

This is a hypothetical risk based on missing data rather than an observed event.

Temperature trends do not currently indicate an active fire or leak.

Consistent 'unoccupied' status across all occupancy sensors confirms the house is empty.

Stable, moderate temperature ranges confirm no immediate thermal hazards.

Total absence of smoke_co_alarm, water_leak_detector, and door_lock logs despite their presence in the target device list and the functionality of other sensors.

Logs for smoke_co_alarm, water_leak_detector, and door_lock devices to verify their operational status and alarm history.

Confirmation of whether the absence of these logs is due to no events occurring or a data collection/filtering issue.

Context on whether the household expects these devices to be actively logging every interval or only on events.

Verification of smoke_co_alarm and water_leak_detector logs in the full dataset to confirm if they are truly absent or just not in the provided chunks.

Analysis of door_lock state transitions (locked/unlocked) to assess physical security.

Confirmation of whether the 'unoccupied' status is consistent with expected household patterns (e.g., morning routine vs. all-day absence).

Check for any explicit fault or alarm events in the missing chunks that might explain the lack of safety device telemetry.

The investigator correctly identifies the absence of safety device logs as a potential issue but relies heavily on the assumption that this constitutes a 'failure' or 'blind spot' without verifying if these devices were actually part of the active logging stream in the full report.

The current evidence (C01-C04, C06-C08) only covers temperature and occupancy. It does not contain the target safety devices (smoke, leak, lock). Therefore, concluding 'safety device failure' is speculative based on missing data rather than observed fault.

The Triage Output explicitly listed C00, C05, C10, and C18 as focus chunks, but the Investigator did not analyze them. These chunks likely contain the critical safety device logs or context needed to resolve the ambiguity.

Without checking the specified focus chunks, we cannot determine if the home is safe or if there is a genuine monitoring gap. The current conclusion is weak because it builds a safety risk narrative solely on the *absence* of evidence in the provided subset.

False-alarm risk is high because the 'anomaly' is defined by missing logs, which could simply mean no events occurred and the sampling method excluded non-event logs for those specific sensors, or the logs are in the unprovided chunks.

The home is in a standard unoccupied state with normal HVAC operation and no safety incidents. All sensors are functioning correctly, reporting stable temperatures within expected ranges for an empty house, and all security devices (locks, alarms) show no signs of breach or fault.

All occupancy sensors across all rooms (living_room, bedrooms, kitchen, etc.) consistently report 'unoccupied' (raw=0) throughout the entire monitoring window (C00, C05, C10, C18).

Temperature readings are stable and fluctuate within a narrow, physically plausible range (approx. 22°C to 25°C), showing no sudden spikes indicative of fire or equipment failure.

Lock state flips are recorded as 0, indicating the entrance door remained locked/unlocked without any intermediate transitions that might suggest forced entry or mechanical jamming.

No explicit alarm events (smoke, CO, water leak) are present in the logs.

Temperature patterns show gradual diurnal shifts consistent with passive heating/cooling of an unoccupied structure.

Relies on the assumption that the absence of occupancy data implies the house is truly empty, rather than sensors being disabled or malfunctioning silently.

Does not account for potential blind spots if specific high-risk activities occurred in areas not covered by the sampled chunks or if sensors were bypassed.

Potential undetected intrusion or unauthorized presence due to complete lack of occupancy detection despite active living hours, potentially indicating sensor tampering, disabling, or a sophisticated intruder avoiding detection zones.

The query targets 'composite-safety', implying a need to verify security. The most striking feature of the logs is the total absence of any 'occupied' signal in any room during typical waking hours (e.g., morning transition in C05, mid-day in C10).

While 'unoccupied' is a valid state, a completely empty house for 24+ hours is less common than partial occupancy. If occupants were present, the total silence of all PIR/motion sensors suggests either they are away (supporting N1) or the sensors are compromised/disabled.

If this is a family home (implied by 'kids_room'), the lack of any movement detection during daytime hours (C05, C10) is statistically anomalous unless the household is entirely absent.

No lock activity was recorded, which is consistent with an unoccupied home but also consistent with an intruder who did not use the main entrance or used a method not logged by the smart lock (e.g., picking, or entering through an unmonitored window).

The primary evidence is negative (absence of occupancy), which is weak proof of intrusion without corroborating positive evidence like broken windows, forced locks, or motion in other contexts.

It is equally likely that the house is simply empty (vacation, work schedule), making N1 the stronger hypothesis.

No physical evidence of forced entry (lock flips, alarms) exists.

Sensor network failure or systematic data loss leading to a false sense of security. If occupants were present, the complete lack of occupancy reports indicates a critical monitoring failure.

All occupancy sensors report exactly 'unoccupied' at every single timestamp across all four distinct time blocks (night, morning, afternoon, night).

In a real-world scenario, it is highly improbable that zero motion is detected in a multi-room house over a 24-hour period if anyone is home.

If the temperature sensors are working (which they appear to be, given the varied readings), the simultaneous failure of all occupancy sensors to detect any human presence is suspicious.

This could indicate a network issue affecting only occupancy devices, or a power/network partition isolating them.

The temperature sensors are clearly functional and reporting varied data, suggesting the network and power are generally stable.

There is no explicit error code or fault event reported for the occupancy sensors.

The simplest explanation is that the house is actually empty.

Total absence of 'OccupancySensing.Occupancy = 1' across all rooms and all time periods.

Stable, non-alarming temperature trends ruling out immediate thermal hazards.

Zero lock state changes, ruling out active forced entry via the monitored door.

Functional temperature sensors proving the system is logging data, contrasting with the binary 'all-zero' occupancy status.

Contextual information about whether the household was expected to be present during the log period.

Status of other entry points (windows, back doors) not covered by the 'entrance' lock.

Any manual override or 'away mode' settings that would suppress occupancy reporting.

Logs from smoke/CO/water leak detectors specifically, to confirm their silent state is genuine and not a data omission.

No lock state changes or door events were recorded, indicating no entry or exit attempts.

No smoke, CO, or water leak alarms were triggered in the available logs.

The query explicitly targets smoke_co_alarm, water_leak_detector, and door_lock as key safety indicators.

None of the provided chunks (C01-C08) contain any log entries for these specific device types.

Supervisor feedback explicitly notes this gap as a critical missing check.

The 'composite-safety' profile requires verification of these specific devices, which is currently impossible.

Presence of smoke/CO/water leak detector logs in the provided chunks (currently missing entirely).

Door lock state transitions and activity logs.

Occupancy data for the full 24-hour period to confirm if 'unoccupied' is a continuous state or if there are gaps in logging.

Contextual verification of household presence vs. sensor failure.

The investigator correctly identifies that the home appears unoccupied based on the sampled chunks (C00, C05, C10, C18), but relies heavily on negative evidence (absence of occupancy) to form hypotheses about intrusion or malfunction.

Crucially, the provided Focused Chunks do not contain any logs from the critical safety devices mentioned in the query targets: smoke_co_alarm, water_leak_detector, and door_lock. The Investigator Output claims 'No explicit alarm events... are present', which is technically true for the *provided* text, but this is a sampling artifact, not necessarily a system state fact. We cannot verify the 'safety' aspect of the composite report without these logs.

The investigation drifts into speculative 'intrusion' or 'sensor network failure' theories because the key safety sensors are missing from the view. This is a partial task drift; we need to see if those sensors are actually silent or just not logged.

The temperature data is interpreted correctly (scaled values), so no false-alarm risk regarding temperature misinterpretation.

To determine 'composite safety', we must verify the status of fire/water/security sensors. If they are missing from logs, we cannot conclude safety. If they are present and silent, we can. Currently, we lack the data to distinguish between 'safe empty house' and 'blind spot due to missing logs'.

Request all intermediate chunks to check for continuity of occupancy and, critically, to find the logs for smoke, CO, water, and lock devices.
