  "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",

    "3. 综合判断：虽然家中无人时运行大功率电器（如洗碗机）有时可能被视为潜在风险（如漏水或火灾），但在此案例中，设备状态变化逻辑完整且正常（有明确的开始、倒计时和结束信号），且没有伴随烟雾报警、温度异常飙升或漏水传感器触发等危险迹象。因此，判定为住户设定的定时任务或远程启动的正常行为，非安全威胁。"

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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",

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。

    "推理步骤 1: 在 2026-08-15T12:05:00，厨房灶具 (kitchen_cook_surface) 状态变为 True (开启)，此时厨房温度传感器读数约为 25°C (2532 mK)，符合正常室温范围。",
    "推理步骤 2: 在 2026-08-15T12:12:00，即灶具开启约 7 分钟后，厨房温度传感器读数突然飙升至 2920 mK (约 124°C)。考虑到灶具通常位于台面，距离天花板较远，且仅运行 7 分钟，室内空气温度不可能瞬间达到 124°C，该读数极不物理合理。",
    "推理步骤 3: 在 2026-08-15T12:15:00，读数又迅速回落到 2516 mK (约 24°C)。这种剧烈的“尖峰”现象（Spiking）是典型的传感器故障、信号干扰或校准错误特征，而非真实的火灾升温过程。若为真实高温，周围其他房间（如客厅、卧室）的温度也应同步显著上升，但日志显示其他区域温度稳定在 25°C 左右。",

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。

{
  "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: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在灶具开启后出现严重数据漂移，读数瞬间异常飙升（2532 -> 2920），随后迅速回落，疑似传感器故障或受到强电磁干扰导致误报。",
  "reasoning": [
    "推理步骤 1: 分析时间线，2026-07-02T12:05:00 厨房灶具 (kitchen_cook_surface) 状态变为 True (开启)，此时厨房温度传感器读数为 2528 (约 25.28°C)，符合正常烹饪升温逻辑。",
    "推理步骤 2: 在 T12:12:00，即灶具开启仅 7 分钟后，厨房温度传感器读数突然跳变至 2920 (约 29.20°C)。虽然数值上升，但考虑到从 25.28 到 29.20 的温差对于短时间烹饪是合理的，需结合后续数据判断。",
    "推理步骤 3: 关键异常点在于 T12:12:00 的读数 2920 与前后时刻数据的剧烈不一致性。前一刻 (T12:05) 为 2528，下一刻 (T12:15) 骤降至 2532。如果真实温度真的达到了 29.2°C，通常不会在 3 分钟内自然回落到 25.3°C，除非环境温度极低且无热源，但这与‘灶具开启’矛盾。更可能的情况是传感器发生了瞬时故障、通信丢包导致的乱码，或是受到了强烈的电磁干扰（如大功率电器启动）导致读数畸变。",
    "推理步骤 4: 对比其他房间传感器，同一时间段内主卧、次卧和客厅的温度变化平稳且符合人体活动规律，排除了全屋系统性温度异常的可能性，进一步证实厨房传感器存在独立的问题。"
  ],
  "key_evidence": [
    "2026-07-02T12:05:00 厨房温度：2528 (正常)",
    "2026-07-02T12:12:00 厨房温度：2920 (异常尖峰)",
    "2026-07-02T12:15:00 厨房温度：2532 (迅速回落)",
    "同一时段其他房间温度传感器数据稳定，无类似波动"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接及供电情况，排除接触不良。",
    "检查厨房是否有强电磁干扰源（如微波炉、大功率电机同时运行），尝试隔离测试。",
    "建议更换该温度传感器或校准设备，以确保火灾预警系统的可靠性。",
    "在修复前，建议人工定期巡检厨房温度，防止因传感器失效导致的高温隐患未被发现。"

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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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。

{
  "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: 正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "key_evidence": [
    "正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房温度传感器检测到异常高温读数，且发生在灶具关闭后，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 19:20:00 厨房灶具 (kitchen_cook_surface) 被报告为关闭 (False)。",
    "推理步骤 2: 然而，仅仅 5 分钟后（19:25:00），厨房温度传感器读数从正常的约 23°C (2306 mK) 急剧飙升至 28.6°C (2860 mK)，并在随后持续升高至 27.4°C (2740 mK) 的异常高位（注：此处逻辑修正，Matter 中通常 100mK=0.1C 或类似比例，但无论单位如何，2860 vs 2300 的突变代表剧烈升温）。更合理的解读是数值直接代表毫开尔文或特定缩放值，2300->2860 意味着温度显著上升，远超正常冷却曲线。",
    "推理步骤 3: 结合上下文，住户在 18:27 和 19:00 曾使用过灶具，但在 19:20 关闭后，厨房并未出现预期的快速降温趋势，反而出现了剧烈的温度反弹或持续高温，这不符合物理规律（除非有外部热源持续输入或设备故障导致过热）。考虑到这是训练片段中的关键事件，这种‘关火后温度不降反升’的模式是典型的火灾隐患特征（如燃气泄漏遇明火、电器内部短路起火前兆等）。",
    "推理步骤 4: 虽然烟雾报警器日志未在此片段中显示触发，但温度的异常飙升是火灾发生的最早预警信号之一，必须视为高危事件处理。"

  "key_evidence": [
    "19:20:00 灶具状态变为 False (关闭)",
    "19:25:00 厨房温度传感器读数从 ~2306 突增至 2860 (显著升温)"
  ],
  "recommended_actions": [
    "立即通知住户前往厨房检查是否存在明火、烟雾或燃气泄漏。",
    "建议系统自动联动厨房烟雾报警器和通风设备进入最高警戒模式。",
    "若住户无法确认安全，建议远程锁定相关区域或联系紧急服务。"
