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。

  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，所有设备日志符合正常住户作息规律。",

    "1. **作息规律性分析**：对比8月20日、21日和22日的活动摘要及详细日志，住户的起床时间（约06:25-06:40）、出门时间（约07:24-07:36）和晚间活动时间（20:45左右）在三天内保持高度一致。这种重复性的行为模式表明是常态化的日常生活，而非突发异常。",
    "2. **门锁与出入安全**：日志显示每天早晨出门前，入户门传感器均先变为False（开门），随后门锁执行LockOperation Type 1（上锁），紧接着Type 0（解锁/复位状态确认）。这是典型的“离家落锁”操作序列，且发生在合理的时间窗口内，无非法入侵迹象。",
    "3. **环境与安全设备状态**：温度传感器读数随时间缓慢变化，符合室内热惯性特征，无突变或漂移。厨房灶具(cook_surface)和烟雾报警器(smoke_co_alarm)在日志期间未触发任何报警或异常开启事件，排除了火灾或未关火风险。",
    "4. **传感器功能正常**：运动传感器(occupancy_sensor)在无人时报告0，有人时报告1，且与灯光开关逻辑基本吻合（如卧室灯亮起伴随卧室有人），未发现传感器卡死(stuck)或失灵(malfunction)的迹象。"
  ],
  "key_evidence": [
    "连续三天早晨07:24-07:36之间出现一致的 'Door Open -> Lock -> Unlock' 序列，确认为正常的离家行为。",
    "起床后卧室灯、卫生间灯依次开启，随后客厅运动传感器激活，符合人类晨间洗漱、活动的自然流程。",
    "全天无烟雾报警器触发、无漏水传感器报警、无门窗非授权开启记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则（如离家自动落锁），并定期备份智能家居配置以防数据丢失。"
  ]
}
```

Rejected response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "触发时间位于清晨起床窗口且有轻微抖动，不是固定的可疑重复模式。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}

    "1. 分析门锁与门磁状态变化：在 07:45:30 至 07:45:34 期间，门锁先解锁（LockState=2）后上锁（LockState=1），同时门磁短暂显示开启（False）后关闭（True）。这通常对应于住户手动开门进入后立即关门并反锁，或者住户在门口进行短暂的检查/调整动作。",
    "2. 关联运动传感器验证：在门锁操作的同时（07:45:33），玄关运动传感器（entrance_occupancy）由 0 变为 1，证实了有人物实体出现在该区域，排除了设备误报或无人触发的可能性。",
    "3. 排除异常模式：虽然 08:02 再次出现门锁解锁和门磁开启，但随后在 08:03 迅速恢复锁定状态，且中间间隔较短，结合早晨时段（07:00-08:00）的生活习惯，这极有可能是住户出门、忘记带东西返回重新确认门锁，或者是智能场景下的自动测试/误触后的快速修正。整个过程中没有持续的门未关、长时间非法入侵迹象，也没有与其他房间异常活动联动，因此判定为正常行为。"

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。

  "threat_description": "日志显示为正常的居家活动模式，入户门在早晨离家时上锁，傍晚回家时解锁并开灯，夜间再次上锁，所有行为符合住户日常作息逻辑。",
  "reasoning": [
    "1. 分析早晨离家行为：07:40左右，门锁执行手动上锁（LockState=2），随后门磁传感器显示门关闭（False）又短暂打开（True，可能是未关严或误触后重关），最终门锁保持锁定状态。这符合住户出门离家的正常操作。",
    "2. 分析傍晚回家行为：18:19左右，门锁执行手动上锁事件（注意：此处日志记录为LockOperation Type=1即上锁，但结合后续14:05的解锁和18:19的时间点，通常回家是解锁。然而仔细看14:05-14:06序列：14:05 LockState=2(锁), Contact=False(关), Light=True(开)。这看起来像是一次短暂的测试或误报，或者住户在14:05并未真正离开而是从外面回来？不，14:05是锁，14:06灯亮。再看18:19，日志显示LockOperation Type=1 (Lock) 且 LockState=2。如果住户是回家，应该是Unlock。这里存在一个潜在的歧义：Matter协议中Type=1通常是Lock，Type=0是Unlock。18:19发生的是Lock操作。但是，紧接着18:19:02门磁变为False（门关），18:19:14灯亮。如果18:19是上锁，说明住户可能是在家里反锁，或者这是一次异常的上锁记录。但结合19:24客厅有人（Occupancy=1），且21:50发生了Unlock操作（Type=0, LockState=1），说明住户在21:50之前是在家中的。因此，18:19的“上锁”更可能是住户在家中进行的反锁操作，或者是系统对“关门”动作的某种误读，但关键在于之后有持续的室内活动证据。",
    "3. 验证室内活动连续性：19:24、20:49、22:14、23:39客厅运动传感器多次触发（Occupancy=1），证明住户在傍晚回家后一直在家活动，直到深夜。这与18:19之后的状态一致。",
    "4. 分析夜间安全行为：21:50左右，门磁变为True（门开？不，Contact Sensor True通常代表门打开，但在某些配置下False代表Closed/Secure。需结合上下文。看07:40序列：Lock后Contact=False，然后True，最后Lock。看21:50序列：Light Off -> Contact=True -> Unlock(LockState=1) -> LockState=1。这里Contact=True表示门被打开，随后执行了Unlock操作（Type=0）。这非常符合住户准备睡觉前检查门窗，或者仅仅是门没关好被传感器检测到，随后住户进行了确认或处理。更重要的是，21:50之后没有新的进入/离开记录，且室内持续有人，符合睡前准备或休息前的状态。",
    "5. 综合判断：整个时间线展示了典型的‘早出晚归’模式。早晨上锁离家，白天无活动（Occupancy多为0），傍晚回家（尽管18:19日志标记为上锁，但结合后续室内有人及21:50的解锁/开门动作，整体逻辑自洽为居家状态），夜间室内持续有人。未发现非法入侵、长时间无人却开门等高危异常。"

    "2. 设备状态一致性：客厅窗户传感器在10:05报告关闭（False），随后客厅灯在10:07再次开启，这与老人可能刚关好窗户并继续活动的场景一致。没有发现门窗异常开启或长时间无人却有人体感应的矛盾情况。",
    "3. 环境数据正常：温度读数在24-26摄氏度之间波动（Matter协议中通常单位为0.01度，即24.39°C-25.56°C左右），处于舒适区间，无火灾或极端天气导致的异常温升。烟雾报警器和一氧化碳报警器无任何触发记录。",
    "4. 排除健康风险：虽然老人独居，但运动传感器在短短两小时内多次在不同房间激活，表明老人行动能力尚可，没有发生长时间静止不动（可能跌倒或昏迷）的“abnormal_inactivity”迹象。"

  "threat_description": "客厅温度传感器读数严重偏离物理常识（约 25°C 显示为 2540+），且数值波动无规律，表明传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现 living_room_temp_sensor 的 MeasuredValue 在 2536 到 2560 之间跳动。考虑到 Matter 协议中温度通常以 0.1 度为单位，该数值实际代表约 25.36°C 至 25.60°C，这在夏季是合理的室温范围。然而，若系统未进行单位转换直接展示原始值，或者传感器本身发生了严重的漂移/故障导致数值异常放大（例如本应是 25.40 却报 2540），则需警惕。但更可能的情况是：这是一个**传感器故障（Sensor Malfunction）**导致的读数异常，因为正常室温不会在短时间内剧烈震荡（如从 25.39 瞬间跳到 2550 再跳回 2536），这种高频、大幅度的非物理性波动不符合热力学规律。",
    "推理步骤 2: 结合住户画像（独居老人）和环境背景。虽然 25°C 左右是舒适温度，但如此频繁且剧烈的数值跳动（每几分钟一次，幅度达 10-20 个单位）极不自然。如果是真实的温度变化，通常需要空调或门窗开合引起缓慢变化，而不会像心电图一样剧烈抖动。",
    "推理步骤 3: 对比其他房间数据。bedroom_temp_sensor 和 kitchen_temp_sensor 的数值相对稳定（卧室约 24.4-24.6，厨房约 25.3-25.6），且变化平缓。唯独客厅温度传感器表现出明显的“噪声”特征。这种单一设备的异常行为排除了全屋环境突变的可能性，指向设备本身的硬件故障、校准错误或通信干扰。对于独居老人家庭，错误的温度读数可能导致温控器误判，进而引发过度制冷/制热，增加老人健康风险或能源浪费。",

  "reasoning": [
    "1.  occupancy_sensor (运动传感器) 持续报告 Occupancy = 0：在上午9:00至11:00期间，客厅、卧室、卫生间的运动传感器均显示无人。结合时间（工作日白天），这符合住户外出上班或不在家的正常状态。",
    "2.  window_contact (窗户传感器) 状态为 False：日志中 living_room_window_contact 和 bedroom_window_contact 的 BooleanState.StateValue 均为 False。在 Matter/智能家居标准中，Contact Sensor 通常 'True' 表示关闭（Closed/Secure），'False' 表示打开（Open）。然而，即使假设 'False' 代表窗户开启，也没有伴随入侵迹象（如门锁异常、夜间活动）。更常见的情况是，如果窗户一直开着，传感器会持续上报该状态，而不会触发突发的安全警报，除非有特定的自动化规则被违反。但在此片段中，没有看到门锁被非法开启或烟雾报警等紧急事件。*修正思考*：通常 Contact Sensor 逻辑是 Closed=True, Open=False。如果窗户开着，且有人在家，可能只是通风。但这里所有人都不在家（Occupancy=0）。如果窗户开着且没人，可能存在安全隐患（盗窃风险），但题目要求判断“实时设备事件”是否为“异常安全事件”。在没有其他入侵证据（如门被撬）的情况下，仅凭窗户状态（无论开闭）且无人在家，通常归类为需要检查的状态，而非即时的“入侵”或“故障”威胁。但仔细看日志，10:05 和 10:06 才出现窗户状态变化/记录，之前只有温度。这可能意味着窗户刚刚被操作过，或者这是初始状态上报。鉴于 Occupancy 全为 0，且无其他异常，最合理的解释是住户离家，窗户处于某种状态（可能是为了通风，也可能是忘记关）。但在缺乏“非法闯入”行为（如门锁解锁、快速移动）的情况下，将其判定为 High Confidence 的 Threat 是不准确的。更重要的是，看 threat_type 列表，没有 'unsecured_window' 选项。如果有 'intrusion'，需要更多证据。如果没有 'intrusion'，且窗户开着不算 'sensor_malfunction'（因为它是真实反映状态），那么它属于 'none' 或者低风险的 'behavioral_anomaly'（如果用户习惯关窗）。但考虑到 Occupancy 为 0 持续数小时，且最后灯光在 18:09 亮起，说明住户晚上回来了。整个过程没有发现‘正在发生’的攻击或故障。",
    "3.  灯光控制正常：living_room_light_1 在 10:07 开启，18:09 再次开启，21:49 关闭。这些时间点符合人类作息规律（上午回家/活动，傍晚回家，晚上休息）。特别是 10:07 的亮灯与 10:05-10:06 的窗户状态记录几乎同时，暗示住户可能在 10:05 左右回到了家中并打开了窗户和灯？等等，如果 10:05 住户回来，为什么 10:05-11:00 的 occupancy_sensor 还是 0？这可能是传感器延迟，或者住户非常安静地移动未被捕捉，或者住户只是在门口/玄关（entrance）活动而未进入客厅触发 motion sensor。但 entrance 的 motion sensor 未在重点设备中列出，不过 bathroom/bedroom/living_room 都报 0。如果住户真的进屋了，通常会在某个房间停留。另一种可能是：10:05 的窗户状态变化是住户离开时做的，或者之前就一直开着。关键在于 10:07 灯亮了。如果灯亮了，人肯定在附近。但 Motion Sensor 没动。这可能是因为 Motion Sensor 有盲区，或者用户使用了非运动触发的开关。这不构成安全威胁。",
    "4.  综合判断：所有传感器读数（温度波动正常，门窗状态稳定，无人占用）和设备动作（灯光按时开关）均未表现出入侵、火灾、泄漏或设备故障的特征。虽然窗户状态和灯光开启的时间点有些许巧合，但没有证据表明存在恶意行为或系统错误。"

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。
