    "3. 确认最终状态：07:40:39 门锁再次记录手动操作并变为解锁状态（LockState=1）可能是误读或特定协议下的状态同步延迟，但结合08:02的日志看，系统在08:02明确记录了门锁为锁定状态（LockState=2）且门磁为关闭（False）。更重要的是，08:00时所有主要活动区域（客厅、次卧、卫生间）均无人，仅主卧有人，随后主卧也保持有人状态直到08:11，这通常意味着住户已离开家（可能从其他出口离开或传感器覆盖盲区），或者住户仍在室内但处于非公共区域。然而，最关键的证据是07:40-08:02之间门锁从解锁变为锁定，且门磁闭合，这是标准的‘离家’动作。没有发现强行破拆、多次错误尝试或异常的时间间隔（如深夜非法入侵）。"

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。

    "3. 就寝模式识别：19:30 起卧室运动传感器归零，20:00 卧室持续无人，20:02 门锁再次上锁（可能是确认反锁或误触，但结合后续动作看更像系统状态同步或二次确认），20:04 玄关灯开启（可能为起夜或检查）。整体时间线符合典型的晚间作息规律。",

## 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。

Chosen response:

{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，所有设备活动符合正常的家庭作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：连续三天（7月8日-10日）的日志显示高度一致的作息模式。早晨6:30-7:30之间，玄关和卫生间传感器被触发，随后入户门解锁并离开，符合典型的上班/出门流程。晚上19:00后客厅有人活动，符合下班回家后的状态。",
    "2. **门锁操作合规性**：7月8日和9日的早晨，门锁在接触传感器关闭（门关上）后执行了手动上锁（LockOperationType=0），这是标准的离家落锁行为。7月10日早晨虽然先执行了开锁（Type=1），但紧接着接触传感器变为False且Occupancy为1，结合后续逻辑可能是测试或特殊操作，但整体并未出现非法入侵迹象（如深夜开门、多次失败尝试等）。",
    "3. **环境数据正常**：温度传感器读数随时间缓慢变化，夜间较低（约24.5°C），白天逐渐升高至25.0°C以上，无剧烈跳变或传感器卡死（Stuck）的迹象。厨房灯在早晨短暂开启后熄灭，未见长时间无人烹饪导致的火灾隐患。",
    "4. **无异常事件关联**：未发现烟雾报警、漏水检测、一氧化碳报警等安全设备的触发记录。运动传感器与灯光控制逻辑一致，无长时间静止不动（可能跌倒）或异常活跃的情况。"
  ],
  "key_evidence": [
    "连续三天早晨07:23-07:26期间，entrance_occupancy=1 -> front_door_contact=False -> front_door_lock LockOperation(Type=0)，确认为正常的离家离锁行为。",
    "温度传感器数值在2439-2538范围内平滑波动，无突变或停滞，排除传感器故障。",
    "全天无 smoke_co_alarm 或 water_leak_detector 触发记录。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查门锁电池电量，确保自动落锁功能稳定。"
  ]

Rejected response:

    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [

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。

    "1. 活动模式分析：过去三天（7月22日-24日）的活动高度一致。每天早晨06:30-07:30之间，卫生间、卧室和客厅的运动传感器依次触发，伴随灯光开启，随后在07:30左右客厅 occupancy 归零，表明住户起床、洗漱、离开客厅。晚上19:28-19:39左右客厅 occupancy 再次触发，表明住户回家。这种规律性的“晨起-离家”和“傍晚回家”模式是典型的正常生活轨迹。",
    "2. 门锁操作验证：7月23日07:24记录到入户门先解锁后上锁的操作，且发生在住户离开客厅之后、出门之前。这符合住户出门前检查门锁或顺手反锁的习惯，并非异常入侵或故障。其他两天虽无详细门锁日志，但结合 occupancy 变化，逻辑自洽。",
    "3. 传感器数据合理性：温度传感器读数随时间缓慢上升（夜间至清晨），符合室内热惯性特征，无突变或停滞现象，排除传感器卡死或漂移故障。运动传感器状态切换清晰，无长时间静止后的突然误报或持续误报。",
    "4. 关键设备联动正常：厨房灯仅在早晨短暂开启（07:11-07:26, 07:24关闭），符合早餐准备场景；7月24日早晨厨房灯开启与客厅 occupancy 触发几乎同步，符合日常行为。未发现无人时的长明灯或异常烹饪行为。"

## 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。

Chosen response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示独居老人的日常作息规律且符合预期。",
  "reasoning": [
    "1. **作息模式一致性分析**：对比2026-08-29至31三天的数据，住户的起床时间（卧室/厨房活动开始）稳定在05:45-06:10之间，离开客厅（living_room_occupancy归零）的时间稳定在08:00左右。这种高度一致的时间窗口表明住户生活规律，无突发性行为改变或异常滞留。",
    "2. **烹饪与用火安全**：日志中仅出现一次灶具开启事件（08-29 06:06），随后在06:50关闭，持续约44分钟，属于正常的早餐准备时长。三天内均未触发烟雾报警器（smoke_co_alarm），且厨房温度传感器读数正常（2470-2510范围，对应约24-28°C，Matter协议通常以0.01度为单位，此处数值需结合具体换算，但相对变化平稳，无剧烈升温报警迹象）。",
    "3. **门锁与入侵检测**：入户门传感器仅在早晨时段（06:50和07:09）记录到状态变化（LockState=2通常表示锁定或特定状态，配合Contact=True可能为关门上锁动作），这与住户出门上班或外出的逻辑相符。夜间及清晨其他时段门窗均保持关闭/锁定状态，无非法入侵迹象。",
    "4. **健康与安全监控**：卫生间运动传感器在早晨有短暂活动（如08-30 06:28, 08-31 06:04），符合洗漱习惯。未发现长时间无活动的“abnormal_inactivity”警报，也未发现跌倒相关的紧急求助信号。"
  ],
  "key_evidence": [
    "连续三天早晨05:45-06:10期间卧室和厨房传感器被激活，显示规律的起床行为。",
    "08-29 06:06-06:50期间厨房灶具开启，随后关闭，无烟雾报警，属正常烹饪。",
    "早晨06:50-07:10期间入户门锁和接触传感器有操作记录，符合出门逻辑。",
    "全天各区域温度传感器读数平稳，无异常波动或火灾高温特征。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器，确保Matter协议下的温度数值解析准确（确认MeasuredValue的单位换算标准）。"

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房灶具在无人看管的情况下长时间开启，且伴随温度异常升高，存在极高的火灾风险。",

    "推理步骤 2: 对比同一时间段的 occupancy_sensor 数据，发现每次灶具开启后，厨房运动传感器 (kitchen_occupancy) 虽然短暂显示有人 (Occupancy=1)，但在随后的几分钟到十几分钟内（例如 06:16 至 06:50），厨房区域频繁出现无人状态 (Occupancy=0)，而灶具并未自动关闭。",
    "推理步骤 3: 结合独居老人背景，这种‘人离开但灶具未关’的模式重复出现，且厨房温度传感器读数持续攀升（从 24°C 升至 25°C+），表明设备处于无人看管的加热状态，符合 unattended_cooking 特征，极易引发火灾。",
    "推理步骤 4: 尽管有烟雾报警器，但日志中未触发报警事件，说明当前主要风险是预防性的火灾隐患，而非已经发生的火情。"

    "立即联系住户或其紧急联系人，确认家中安全状况。",
    "建议远程检查或安排人员上门查看厨房灶具及周围环境是否有烟熏痕迹或异味。",

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。
