你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "threat_type": "behavioral_anomaly",
  "threat_description": "老人用餐时间逐步推迟",
  "reasoning": [
    "推理步骤1: 厨房活动时间逐日明显变晚",

  ],

  ]
}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，设备状态与住户行为逻辑一致，未发现安全威胁或异常。",
  "reasoning": [
    "温度数据合理性分析：所有温度传感器（客厅、厨房、卧室）报告的数值均在 2500-2600 范围内（即 25.0°C - 26.0°C），符合夏季室内正常室温范围，且随时间推移有自然的昼夜波动趋势，排除了 sensor_drift 或 sensor_malfunction 的可能性。",
    " occupancy 模式一致性：运动传感器在白天（10:30-17:00）频繁检测到人员活动，夜间及清晨时段无异常长时间无人状态，符合独居老人白天的生活规律；卫生间和厨房的占用情况也与烹饪、洗漱等日常行为吻合。",
    "设备联动逻辑正常：厨房灯开启通常伴随厨房有人或灶具使用（虽未直接看到灶具开火事件，但有人在场且温度升高是合理的）；窗帘开合时间与光照变化或用户手动操作习惯相符；入户门传感器仅在特定时间点触发，未见非法入侵迹象。",
    "关键风险排除：烟雾报警器、漏水传感器、门锁等关键安全设备在日志中未报告任何故障或异常触发事件，且环境参数稳定，不存在 fire_risk、water_leak 或 intrusion 的迹象。"
  ],
  "key_evidence": [
    "温度读数始终在合理区间 (24.0°C - 26.0°C) 内波动，无突变或极端值。",
    "各房间 occupancy 状态变化连贯，反映了正常的日间活动周期，无长时间静止后的突然闯入或异常离开。",
    "厨房灯 (kitchen_light) 的开启时间与厨房有人 (kitchen_occupancy=1) 的时间高度重合，符合正常家务行为逻辑。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，定期查看日志摘要以确保模式未发生长期漂移。",
    "鉴于住户为独居老人，建议家属或照护者每日进行一次电话问候，确认其身体状况良好。"
  ]
}

System:
你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

请按以下 JSON 格式回答：

  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房在无人状态下出现持续高温且伴随灯光开启，存在严重的火灾隐患。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:05，此时独居老人通常处于睡眠状态（符合跨天摘要中卧室和客厅长时间无人的情况）。",
    "推理步骤 2: 异常行为识别。在 02:10 厨房运动传感器检测到有人 (Occupancy=1)，随后在 02:50 厨房灯被打开 (OnOff=True)。然而，从 02:30 开始直到日志结束，所有房间（包括厨房、卧室、客厅）的运动传感器均报告为 0 (无人)。这表明有人在深夜进入厨房后离开，或者传感器误报，但结合后续温度变化，更可能是有人短暂活动后离开，或设备故障导致‘幽灵’占用信号消失。",
    "推理步骤 3: 危险模式确认。最关键的是温度数据：厨房温度从 02:10 的约 23.4°C (2340 mK) 急剧上升至 04:00 的约 24.0°C (2404 mK)，并在短时间内达到峰值 2396-2404 mK (约 24°C)。虽然绝对温差不算极大，但考虑到这是夜间无人值守时段，且厨房灯被打开，这种持续的高温趋势极有可能是灶具未关闭导致的加热现象。对于独居老人，夜间忘记关火是典型的高风险场景。",
    "推理步骤 4: 综合判断。厨房灯开启 + 持续高温 + 无人状态 = 极高的火灾风险。烟雾报警器未在日志中触发报警事件，可能意味着尚未达到报警阈值，但风险已迫在眉睫。"

  "key_evidence": [

    "02:10 - 04:00 期间 kitchen_occupancy 持续为 0 (无人)，但 kitchen_temp_sensor 读数从 ~2340 持续攀升至 ~2404 (约 24°C)"
  ],
  "recommended_actions": [
    "立即远程通知住户或紧急联系人，告知可能存在忘关火源的情况。",
    "检查厨房烟雾报警器是否正常工作，若未报警需人工现场确认是否有明火或浓烟。",
    "建议系统配置自动联动：当检测到厨房温度异常升高且无人时，自动切断厨房电源或启动排风/警报。"

System:
你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "reasoning": [
    "1. 环境状态分析：从 02:10 到 04:10，厨房运动传感器（kitchen_occupancy）多次报告为 0（无人），且客厅、卧室等其他房间也处于无人状态，表明此时家中无人在场。",
    "2. 异常数据识别：尽管无人活动，厨房温度传感器读数却呈现持续上升趋势。从 02:10 的 2340 (°C*10) 即 23.4°C 开始，温度稳步攀升，至 03:55 达到 2399 (23.99°C)，并在 04:00 达到峰值 2410 (24.1°C)。",
    "3. 逻辑矛盾与风险推断：对于独居老人家庭，凌晨时段厨房温度在无人为干预下自然上升极不寻常。虽然数值看似未达明火燃烧的高温（通常>60°C），但结合 Matter 协议中常见的整数缩放比例（此处可能为 x10），若实际温度已达 24°C 以上且持续上升，或者该传感器本身发生了漂移/故障导致误报高温，均构成潜在风险。更关键的是，如果这是真实温度且持续上升，可能预示着灶具余热未散、电器过热或潜在的阴燃火情初期阶段，而住户因睡眠无法察觉。",
    "4. 排除正常行为：日志显示厨房灯（kitchen_light）在 02:50 开启，随后无人操作，温度却继续飙升，排除了正常烹饪后关闭电器的可能性，符合‘无人看管下的异常热源’特征。"

System:
你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "threat_description": "老人连续多天活动范围缩小",

Rejected response:

    " occupancy 逻辑自洽：各房间的人员占用状态（OccupancySensing.Occupancy）随时间流动自然切换，例如从卧室移动到客厅再到厨房，没有出现长时间无人却频繁触发运动传感器的情况，也未发现人员进入后长时间静止不动的跌倒风险特征。",
    "关键安全设备工作正常：烟雾报警器、漏水传感器等未在日志中报出故障或触发报警事件，且窗户接触传感器未检测到非法入侵（如门开人未进或窗开人未动）。"

  "key_evidence": [
    "门锁事件 front_door_lock 仅在早晨和傍晚出现，且操作源为 Manual，无异常解锁尝试。",

  ],
  "recommended_actions": [
