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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "carbon_monoxide",
  "threat_description": "厨房一氧化碳浓度持续上升，且灶具已关闭，存在潜在的一氧化碳泄漏或燃烧不充分风险。",
  "reasoning": [
    "1. 识别到关键安全指标异常：日志显示 `kitchen_smoke_alarm` (烟雾报警器) 的 `CarbonMonoxideConcentrationMeasurement.MeasuredValue` 在 21:00 至 21:40 期间从 35 ppm 逐步上升至 59 ppm。虽然尚未达到立即致命的极高浓度，但呈现明显的上升趋势，且远超正常背景值（通常 < 5-10 ppm）。",
    "2. 排除烹饪干扰：导致 CO 升高的主要源头通常是燃气灶具。然而，日志显示 `kitchen_cook_surface` (灶具) 在 19:41 已经关闭 (`OnOff = False`)。这意味着在 CO 浓度开始显著上升的时间段（21:00后），并没有正在进行的明火烹饪活动来解释这一读数。",
    "3. 结合环境与其他设备状态：在此期间，厨房窗户传感器 `kitchen_window_contact` 在 19:41 变为 False (关闭)，之后未再打开，表明通风可能不足。同时，其他房间温度稳定，无火灾迹象（如温度骤升），排除了外部火灾导致的烟雾/CO涌入。",
    "4. 综合判断：在灶具关闭的情况下，室内 CO 浓度仍持续攀升，这强烈暗示存在隐蔽的一氧化碳来源（如燃气热水器故障、烟道倒灌或管道轻微泄漏）或传感器本身出现漂移/故障。鉴于 CO 的致命性，必须视为真实威胁处理。"

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",

    "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。

    "2. 排除误报与正常烹饪干扰：虽然19:26有灶具关闭记录，但CO浓度在两个小时后才开始显著上升，且此时洗碗机正在运行（19:37开启），通常洗碗机不产生大量CO。更重要的是，CO浓度的持续累积而非瞬间峰值，更符合缓慢泄漏或通风不良导致的积聚特征。",
    "3. 结合环境背景：同一时间段内，厨房温度传感器读数从约22.9°C逐渐下降至22.5°C左右，表明没有发生剧烈的高温火灾（fire_risk），这进一步支持了气体泄漏而非明火燃烧的推断。同时，其他房间人员活动正常，无紧急疏散迹象，说明威胁尚在早期阶段。"

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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "carbon_monoxide",
  "threat_description": "厨房一氧化碳浓度持续上升，存在潜在的燃气泄漏或燃烧不充分风险。",
  "reasoning": [
    "1. 识别关键异常指标：日志显示厨房烟雾报警器（具备CO监测功能）在21:00、21:20和21:40分别报告了一氧化碳浓度为35、48和59（单位通常为ppm）。这是一个明显的上升趋势。",
    "2. 关联设备状态与时间线：虽然灶具在19:28已关闭，但CO浓度在两个半小时后仍在显著升高。这可能意味着灶具阀门未完全关闭导致微量泄漏，或者存在其他燃气源/燃烧设备的问题。",
    "3. 排除误报与环境因素：同期厨房温度传感器读数正常且稳定（约22-23°C），没有剧烈波动，排除了因高温导致的传感器漂移或故障。同时，窗户传感器在19:28显示为False（关闭），如果窗户是打开的，CO可能会迅速扩散稀释，但浓度反而上升，暗示通风不良或泄漏源持续存在。",
    "4. 综合判断：一氧化碳是无色无味的有毒气体，其浓度的持续累积是严重的安全威胁，必须立即干预以防止中毒事故。"
