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。

## 任务
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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",

    "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，日志显示为正常的夜间居家活动模式。",
  "reasoning": [
    "1. 分析时间背景：事件发生在2026-07-02的22:47至23:44之间，属于典型的夜间休息时段。",
    "2. 分析人员流动模式：日志显示玄关（entrance）和客厅（living_room）的运动传感器在22:47、23:07、23:27多次触发Occupancy=1。这种间隔约20分钟的重复触发，符合住户在客厅走动、看电视或短暂停留后离开又返回的正常行为特征，而非入侵者快速通过的特征。",
    "3. 分析睡眠状态关联：卧室（master_bedroom, second_bedroom）在23:00和23:30报告Occupancy=0，表明住户已回到卧室准备休息或正在休息，这与客厅的活动时间线吻合（先活动后入睡）。",
    "4. 排除异常指标：卫生间（bathroom）传感器在23:14和23:44报告Occupancy=0，结合之前的活动，可能意味着住户使用卫生间后离开，或者传感器因长时间无人而复位，没有发现漏水、烟雾或其他危险传感器的报警信号。整体行为逻辑连贯，无暴力破拆、非法闯入或设备故障迹象。"
  ],
  "key_evidence": [
    "玄关和客厅运动传感器在22:47-23:27期间多次触发，呈现规律性居家活动特征",

    "无任何门锁异常开启、烟雾报警或漏水报警记录"
  ],

    "无需采取紧急措施",

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。

请从下面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",

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": [
    "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。

  "reasoning": [
    "1. 门锁与传感器状态分析：22:37:27 入户门接触传感器显示 True（通常表示门打开或处于非锁定/非闭合状态），紧接着 22:37:28 门锁执行了手动上锁操作 (LockOperationType=0) 并变为锁定状态 (LockState=1)。这符合住户回家开门后，在玄关处随手反锁门的正常行为逻辑。虽然时间间隔极短（1秒），但在智能家居日志中，这可能对应于‘进门-关门-上锁’的快速连续动作，或者传感器上报延迟，不构成入侵迹象。",
    "2. 人员活动模式分析：21:56 至 22:59 期间，主卧、餐厅、儿童房、玄关和客厅的运动传感器频繁触发 Occupancy=1，且呈现交替活跃状态。这表明家庭成员正在家中进行正常的晚间活动（如洗漱、休息、走动）。次卧和主卫的 Occupancy=0 表明这些区域无人，符合夜间就寝前的场景。",
    "3. 环境与安全设备分析：温度传感器读数在 22.4°C - 22.6°C 之间波动，属于舒适范围且变化平缓，无异常激增（排除火灾风险）。厨房烟雾报警器、漏水传感器在此期间无任何报警事件。空调和灯光的开关操作（如 22:37 客厅灯和空调关闭）与人员离开客厅的行为一致。",
    "4. 综合判断：所有关键安全设备（门锁、烟感、水浸）均处于正常响应状态，未发现非法入侵、设备故障或危险环境迹象。"
  ],
  "key_evidence": [
    "22:37:28 front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) 结合前序门磁状态，确认为正常上锁行为。",
    "22:37:10 living_room_ac | OnOff.OnOff = False 与 22:37:00 living_room_light_1 | OnOff.OnOff = False 同步发生，符合人走断电的正常习惯。",
    "全时段内无 smoke_co_alarm 或 water_leak_detector 的报警记录。",
    "各房间 occupancy 传感器活动符合晚间居家生活规律，无长时间静止或异常闯入特征。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，确保门锁联动逻辑（如离家自动上锁）正常工作即可。"

Rejected response:

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。

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",

    "推理步骤 4: 虽然之前的高温读数可能包含漂移成分，但最严重的安全隐患在于烹饪结束后传感器停止工作，导致系统无法监测余热是否引发火灾风险，属于典型的传感器失效（Sensor Malfunction）。"
