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",

    "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。

  "threat_description": "厨房温度传感器数据严重异常，数值高达 2700+ (应为 23-28°C)，且伴随烟雾报警器未触发，极可能是传感器故障或校准错误导致误报风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，从 18:05 开始，厨房温度传感器读数出现剧烈且不符合物理规律的跳变（从正常的 24°C 左右瞬间飙升至 2463, 2517, 直至 2714）。",
    "推理步骤 2: 对比其他房间传感器数据，客厅、主卧、次卧的温度均在正常范围（229-235 之间），说明环境温度并未发生极端变化，排除了真实火灾或高温环境的可能性。",
    "推理步骤 3: 尽管厨房温度显示异常高，但日志中厨房烟雾报警器(smoke_co_alarm)和灶具(cook_surface)的状态均为静默或未报告报警事件。如果真实发生火灾或过热，烟雾报警器应已触发。这种‘高温无烟雾’的矛盾现象强烈指向传感器硬件故障、固件 Bug 或通信协议解析错误（Sensor Malfunction）。",
    "推理步骤 4: 虽然用户随后开启了灶具(18:51)，但这发生在异常读数出现之后，因此不能解释之前的异常高温数据。该异常读数可能导致系统误判为火情而采取不必要的紧急措施，或者掩盖真实的早期火情信号（如果传感器逻辑被破坏）。"

    "2. **烹饪与火灾风险排除**：厨房灯（kitchen_light）在多个时间点开启（如07:58, 07:12, 12:10, 19:02, 18:40），这些时间段覆盖了早餐、午餐和晚餐准备时间，符合正常生活规律。日志中未出现烟雾报警器（smoke_co_alarm）报警或灶具（cook_surface）长时间无人看管的异常数据。",

Rejected response:

{

  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（约 250°C+），而厨房和卧室温度正常，表明传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-07-22T06:25:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2484 到 2556 之间波动。由于 Matter 协议中温度通常以 0.01°C 为单位，该数值实际代表 24.84°C 至 25.56°C，这是正常的室温范围。然而，若系统未进行单位转换直接展示原始值，或者用户/系统期望看到的是摄氏度但收到了毫摄氏度或其他单位的原始数据，则会产生误解。但更可能的情况是：观察其他设备如 kitchen_temp_sensor (2518 -> 2552) 和 bedroom_temp_sensor (2424 -> 2434)，它们的数值变化趋势与 living_room 一致且都在合理范围内（假设单位统一）。",
    "重新评估推理步骤 1: 让我们再次仔细检查数值的合理性。如果单位是摄氏度，2500°C 显然不可能。如果单位是毫摄氏度 (mCelsius)，那么 2500 mC = 25.00°C，这是完全合理的室温。因此，仅凭数值本身不能判定为 sensor_drift，除非有证据表明单位设置错误导致显示异常。",
    "推理步骤 2: 寻找真正的异常模式。注意到 2026-07-22T07:30:12 到 07:30:19 期间的事件序列：front_door_lock 先变为状态 2 (Unlocked)，紧接着 front_door_contact 变为 True (Door Open)，随后 front_door_lock 变为状态 1 (Locked)。这是一个标准的开门 - 关门流程，符合住户早晨出门的习惯。",
    "推理步骤 3: 深入挖掘跨天活动摘要中的异常。对比三天数据：2026-07-22 bedroom=219, 2026-07-23 bedroom=67, 2026-07-24 bedroom=218。卧室运动传感器在中间一天（7 月 23 日）的活动量骤降为平时的 1/3，而在前后两天均保持高活跃度（~219）。同时，7 月 23 日的 living_room_occupancy 在白天大部分时间（10:30-13:30）均为 0，直到晚上才有人出现。这种‘白天卧室无人、夜间突然活跃’的模式，结合前一日和后一日的高频卧室活动，极不寻常。",
    "推理步骤 4: 结合上下文判断威胁类型。住户通常在白天（工作/学习）和晚上（休息）都会使用卧室。7 月 23 日白天卧室传感器几乎无触发（仅 67 次 vs 其他天的 219 次），且客厅长时间无人，这不符合常规作息。最可能的解释是：有人在白天进入了房屋并躲藏在卧室（可能是入侵者），但由于某种原因（如窗帘遮挡、传感器角度问题或故意规避）未被检测到，或者住户本人因故全天未进入卧室。考虑到前后两天的规律性，'intrusion'（入侵）的可能性较高，因为入侵者可能会选择白天潜入并在隐蔽处待命，或者住户外出时有人尾随进入。然而，更直接的证据缺失。",
    "修正推理步骤 4: 让我们重新审视温度数据。如果所有温度传感器都报告了 25xx 这样的数值，且厨房和卧室也类似，那么这很可能是正常的室温（25°C左右），只是日志记录了原始整数部分或特定格式。没有单一的温度异常。",
    "最终确认异常点：回到 7 月 23 日的卧室活动量骤降。正常情况下，住户在白天（10:00-18:00）应该会在卧室活动（起床、午休、回家等）。7 月 23 日白天卧室 occupancy 计数极低（67 次），而前后两天高达 219 次。与此同时，7 月 23 日 10:30-13:30 客厅无人。这种反常的‘静默期’在安全监控中是一个强烈的信号。虽然不能完全排除住户当天特殊安排（如全天在办公室且不在家，但这与 7 月 22 日和 24 日的模式不符，且 7 月 23 日晚上有人回来），但在缺乏外部信息的情况下，这种显著的行为偏差应被视为潜在的'behavioral_anomaly'或'intrusion'风险（例如入侵者在白天潜伏）。鉴于卧室是主要休息区，白天的极度安静值得高度警惕。",
    "再次检查日志细节：7 月 23 日 12:07:28 bedroom_occupancy = 0，12:10 卧室温度 2423，12:25 2415，12:50 2402。温度在缓慢下降，说明房间可能无人且空调关闭或自然冷却。这与前后两天白天卧室有人时的温度波动不同。综合来看，7 月 23 日白天的低活动量是核心异常。",
    "结论：最显著的异常是 7 月 23 日卧室运动传感器活动量的急剧下降，与前后两天形成鲜明对比，暗示可能存在非正常居住行为（如入侵者潜伏或住户异常缺席）。"
  ],
  "key_evidence": [

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。

  "reasoning": [
    "推理步骤 1: 在 2026-07-31T19:02:30，厨房灶具 (kitchen_cook_surface) 被开启，随后在 T19:05:00 和 T19:10:00，厨房温度传感器读数从正常的 ~24°C 瞬间跳变至 2414 和 2482（单位应为 mK，即约 24.14°C 和 24.82°C 是合理的，但结合上下文看，若原始数据单位为毫开尔文，2482mK=2.3K 绝对零度附近不合理；若为摄氏度则直接爆表。更可能的情况是：正常室温约 23°C = 29560 mK。日志中 23xx 的数值极可能是以 10mK 或类似比例缩放后的值，或者单位本身就是 mK 但显示逻辑有误。让我们重新校准：2373 mK = 2.373 K? 不对。通常 Matter 传感器返回的是 raw value。假设基准是 273150 (0C * 1000) 或其他。观察序列：2373 -> 2376 -> ... -> 2300。这些数值非常接近 23-24 的范围。如果单位是 0.1°C，那么 2373 = 237.3°C，这不可能。如果单位是 mK (milli-Kelvin)，0°C = 273150 mK。这里的 2373 远小于 273150。这说明该传感器的 `MeasuredValue` 可能是一个经过特定缩放的整数，例如代表 '23.73' 的某种编码，或者单位是 0.01°C？如果是 0.01°C，2373 = 23.73°C，这是合理的室温。",
    "推理步骤 2: 关键异常发生在 T19:05:00 和 T19:10:00。此时灶具已开启。温度读数分别为 2414 (24.14°C) 和 2482 (24.82°C)。虽然数值本身仍在室温范围内，但请注意 T19:03:00 时读数为 None，随后突然恢复并持续上升。更重要的是，对比其他房间：卧室温度稳定在 22°C 左右，客厅在 23°C 左右。厨房作为烹饪区域，开启灶具后温度应显著高于其他房间（通常升高 5-10°C 以上）。然而，厨房传感器读数仅比客厅高出不到 1°C (24.8 vs 23.0)，且随后在 T19:20:00 甚至下降至 22.74°C (2274)，这与正在运行的灶具完全矛盾。",
    "推理步骤 3: 这种‘灶具开启但温度不升反降’且与其他房间温差极小的现象，强烈暗示传感器存在故障（Sensor Malfunction）或数据上报错误（Sensor Drift/Stuck），而非真实的物理环境变化。由于厨房是火灾高风险区，传感器失效意味着失去了关键的早期预警能力，构成了潜在的安全威胁。"

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。

## 任务
请从下面 3 天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",
  "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: ..."
  ],

    "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. **厨房用火安全**：8月19日07:03厨房灯亮起，07:30熄灭；8月20日06:45和12:10厨房灯亮起；8月21日17:16厨房灯熄灭。这些时间段（早晨、中午、傍晚）与常规用餐时间吻合。日志中未出现灶具(cook_surface)长时间开启而无人（occupancy_sensor为0）的情况，也未触发烟雾报警器，因此排除未看管烹饪风险。",
    "3. **传感器数据合理性**：温度传感器读数（如2490-2545等）在合理范围内波动，且随时间推移呈现昼夜温差变化（如8月21日傍晚温度从2358降至2298），无传感器卡死或漂移迹象。运动传感器在夜间（如00:00）显示无人，白天有规律地显示有人/无人切换，符合正常居住状态。",
    "4. **跨天模式一致性**：三天的活动摘要显示各房间活跃度稳定，没有突发的异常高频率事件或长时间的完全静默（除了夜间睡眠时段），表明系统运行稳定，住户生活节奏正常。"

    "厨房灯仅在早晚及午间短暂开启，且伴随其他区域活动，无异常长时开启或无人值守情况。",

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。

请从下面 3 天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。

## 任务
请从下面 3 天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",
  "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:

  "threat_description": "未检测到安全威胁或异常模式，所有设备状态变化符合正常家庭作息规律。",
  "reasoning": [
    "1. 活动模式分析：日志显示典型的日间活动轨迹。早晨（06:30-08:00）厨房灯开启、各房间传感器陆续激活，随后入户门关闭并上锁（07:41），表明住户离家上班/上学。下午至傍晚（17:53后）门锁解锁、玄关及客厅传感器再次激活，空调开启，符合下班回家后的行为模式。",
    "2. 关键设备逻辑一致性：重点关注的 kitchen_light 在三天早晨均于 07:00-07:10 左右开启，且伴随厨房温度传感器读数上升（如 07:15-07:25 期间），暗示可能进行了早餐准备或烧水等常规操作，无长时间无人看管烹饪迹象。living_room_occupancy 在白天大部分时间为 0（离家），晚间为 1（在家），状态切换合理。",
    "3. 环境数据合理性：温度传感器读数随时间呈现自然的昼夜波动（白天较高，夜间/清晨较低），且数值在合理范围内（约 22-25°C 对应 Matter 协议的 scaled value），未发现传感器卡死（数值不变）或漂移（数值突变）的迹象。",
    "4. 安全设备状态：入户门锁在离家时锁定（LockState=1），回家时解锁（LockState=2），无非法入侵尝试记录。烟雾报警器和漏水传感器在日志片段中未触发告警。"
