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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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",

  ],
  "recommended_actions": [

```

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
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

  "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",

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。

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。

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。

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
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。

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。",
  "reasoning": [
    "推理步骤1: 正常样本是短暂低幅波动并回落；异常样本是缓慢连续上升。"
  ],
  "key_evidence": [
    "正常样本是短暂低幅波动并回落；异常样本是缓慢连续上升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "unattended_cooking",
  "threat_description": "检测到厨房灶具在无人看管的情况下长时间开启，且伴随温度异常波动，存在严重火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，2026-08-04T12:00:00 厨房灶具 (kitchen_cook_surface) 被开启，但直到 12:33:00 才关闭，持续了约 33 分钟。",
    "推理步骤 2: 在此期间（特别是 12:00 至 12:25），厨房运动传感器 (kitchen_occupancy) 多次报告为 '1'（有人），但在 12:00 到 12:08 之间以及后续部分时段，人员活动与灶具开启状态的时间重叠度极高，需确认是否有人全程看守。然而，结合独居老人背景，若发生跌倒或突发疾病导致无法移动，极易形成‘人未离开但无法操作设备’的假象，或者更常见的情况是：用户在开启后转身去其他房间（如卧室、卫生间）处理事务，导致灶具处于无人看管状态。",
    "推理步骤 3: 关键风险点在于 12:00 开启后，虽然日志中有多次 occupancy=1 的记录，但缺乏明确的‘用户回到厨房并关闭灶具’的直接关联动作（如先关灶具再出门）。更重要的是，对于独居老人，任何超过 10-15 分钟的烹饪无人看管都是高危行为。此外，11:09 和 12:00 附近出现的温度传感器数据缺失 (None) 可能暗示传感器故障或环境剧烈变化，增加了判断的不确定性，但核心威胁仍是长时间开火。",
    "推理步骤 4: 考虑到住户为独居老人，其反应能力可能下降，长时间开火极易引发火灾或一氧化碳泄漏（尽管 CO 浓度目前较低，但长期燃烧有风险）。系统未能及时自动切断电源或发出强警报，属于安全策略执行层面的隐患。"

    "期间虽有 occupancy 信号，但无法确认用户是否始终在灶台旁操作，存在‘人在别处，灶在开着’的潜在风险。"

    "优化智能家居规则：设置灶具超时保护（例如开启 15 分钟后若无特定手势或语音确认则自动关闭），并针对独居老人启用更频繁的主动关怀提醒。"
