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。

    "排除真实威胁：检查同一时间段内的其他设备日志。7月31日06:50灶具已关闭，08:00前后无温度急剧升高记录，无漏水警报，也无人员活动导致的异常高温。8月1日和2日同样只有温度传感器的缓慢上升（符合夏季早晨室温自然回升规律），没有突发的火灾特征（如温度瞬间飙升）。",
    "结合行为模式：ContaminationState通常在传感器检测到灰尘积累或自身老化时触发，或者在真正检测到烟雾后保持高位。但此处表现为每天早晨08:00准时触发并递增，这种高度规律性的“污染”增加不符合物理世界的随机性（灰尘不会每天整点突然增加），也不符合真实火灾后的残留逻辑。这强烈暗示是传感器固件Bug、时钟同步问题导致的周期性误报，或者是传感器本身存在硬件缺陷导致读数漂移。",

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。

    "1. 分析烹饪行为：日志显示用户在 19:00 开启灶具，19:20 关闭灶具，随后在 19:25 和 19:35 出现了两次极高的温度读数（3050 和 3220）。",
    "2. 评估温度合理性：Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以厘氏度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。正常室温约为 22-25°C (2200-2500)。3050 (30.5°C) 和 3220 (32.2°C) 虽然高于室温，但在刚关闭的灶具附近是可能出现的物理现象（余热）。然而，这两个数值相对于之前的基准值（~2280-2300）有显著跃升，且发生在灶具关闭后不久。",
    "3. 结合独居老人场景与设备状态：对于独居老人，灶具使用后若未完全冷却或存在燃气泄漏/电气短路隐患，温度异常升高是危险信号。此外，如果这是传感器故障（如 stuck 或 drift），也可能导致误报，但鉴于涉及明火/热源设备，必须优先按最高风险处理。",
    "4. 排除其他干扰：19:26 客厅灯光变暗（LevelControl.CurrentLevel = 23），可能是用户调整环境光，与厨房事件无直接关联。运动传感器在 19:30 仍检测到厨房有人，说明用户仍在现场，但无法确认其是否意识到高温或正在处理潜在问题。"

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",

    "2. 排除误报可能性：虽然此时所有房间的运动传感器（occupancy_sensor）均显示为 0（无人），但这对于凌晨 3 点的独居老人环境是正常现象。关键在于温度数据并未呈现火灾初期常见的急剧升温趋势（从 01:50 到 04:45，客厅温度仅在 23°C-24°C 之间波动，属于正常室温范围），这可能意味着烟雾源并非明火燃烧产生的高温，或者是早期阴燃阶段，亦或是传感器故障/误报。但鉴于烟雾报警器的优先级，必须按真实威胁处理。",
    "3. 结合住户情况评估：住户为独居老人，凌晨 3 点处于睡眠状态。若发生真实火情，老人可能因睡眠无法及时察觉并逃生，风险极高。即使最终确认为误报，也需要立即介入以消除隐患并确保人员安全。"

    "3. 环境背景分析：报警时间为凌晨 03:16，此时所有房间的运动传感器（Occupancy）均显示为 0，表明家中无人。虽然温度传感器数值（如 2396）看似异常高，但考虑到 Matter 协议中 TemperatureMeasurement 通常以厘氏度（celsius * 100）或类似缩放因子传输，2396 可能代表 23.96°C 或类似的正常室温范围（取决于具体实现，但即便解读为高温，也远低于火灾瞬间的急剧升温特征，更可能是传感器读数漂移或单位误解，而烟雾报警是更直接的威胁指标）。",

## 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。

  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房灶具开启后，厨房温度传感器读数在极短时间内急剧飙升（从约23°C升至32.2°C），且烟雾报警器未触发报警，存在极高的火灾风险或设备故障隐患。",
  "reasoning": [
    "1. **热源激活与异常升温**：日志显示 `kitchen_cook_surface` 在 19:00 和 19:14 两次开启。紧随其后，`kitchen_temp_sensor` 的读数呈现非自然的指数级增长：19:00 (2361) -> 19:05 (2415) -> 19:10 (2490) -> 19:15 (2552) -> 19:20 (2621) -> 19:25 (3050/2681) -> 19:35 (3220)。在35分钟内上升近10度，且最后时刻达到32.2°C，这远超正常烹饪产生的环境热量累积速度，表明热源直接作用于传感器或发生了剧烈燃烧/过热。",
    "2. **安全设备失效/未响应**：尽管温度急剧升高至危险水平，但同属厨房重点监控设备的 `smoke_co_alarm` 在整个时间段内没有任何状态变化或报警记录。正常情况下，如此剧烈的温升应伴随烟雾探测器的早期预警。这种“高温无报警”的状态是严重的安全漏洞。",
    "3. **排除误报可能性**：虽然 `kitchen_cook_surface` 在 19:20 关闭，但温度并未下降反而继续上升至 19:35 的 32.2°C，这符合火灾初期或设备内部短路过热的特征，而非简单的余热消散。同时，其他房间温度稳定，排除了全屋性环境异常。"
