## 任务
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。

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: ...",

    "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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的晚间家庭活动（烹饪、清洁）及环境数据波动。",
  "reasoning": [
    "1. 活动模式分析：日志主要集中在2026-07-19的傍晚时段（17:40 - 19:25）。在此期间，客厅运动传感器多次触发（Occupancy=1），且厨房灶具在17:53开启，随后洗碗机在18:50开启。这符合典型的下班后回家、准备晚餐并启动清洁设备的正常生活节奏。",
    "2. 设备状态逻辑一致性：厨房窗户传感器在18:50:30关闭（StateValue=False），此时洗碗机刚启动，表明住户可能为了隔音或保温关闭了窗户，或者仅仅是随手关门，这与使用洗碗机的行为不冲突，无入侵迹象。",
    "3. 传感器数据合理性：温度读数（如2300-2500范围，推测单位为0.01摄氏度即23-25°C）随时间呈现自然的昼夜变化趋势（早晨升温，傍晚降温），数值跳变在合理范围内，未发现传感器卡死（stuck）或漂移（drift）导致的异常恒定值或剧烈突变。",
    "4. 无危险信号：虽然使用了灶具，但烟雾报警器未触发，且没有检测到一氧化碳报警或长时间无人看管的烹饪行为（日志中仅记录了开启事件，后续有洗碗机运行等持续活动，暗示有人在场）。门锁和入户门传感器在记录期间无异常开启记录。"
  ],
  "key_evidence": [
    "living_room_occupancy 在 17:41, 18:06, 18:36, 19:21 多次变为 1，表明有人在客厅活动。",
    "kitchen_cook_surface 在 17:53 开启，kitchen_dishwasher 在 18:50 开启，符合晚餐后清洁流程。",
    "所有温度传感器读数在合理区间内波动，无异常恒定值。",
    "无 smoke_co_alarm 触发或 door_lock 异常操作记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持常规监控，确保烟雾报警器电池电量充足。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "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": [

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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

    "3. 傍晚回家分析：17:44 主卧传感器检测到活动，17:49 玄关检测到人员进入，17:56 门锁状态变为解锁（LockState=2通常表示未锁定/可进入），随后客厅空调开启（17:56）和灯光开启（18:30），符合下班回家的场景。",
    "4. 烹饪安全分析：18:41 厨房灶具开启，18:53 关闭，持续时间约12分钟，属于正常的短时烹饪行为。期间无烟雾报警器触发，也无长时间无人看管的情况，不存在火灾风险。",
    "5. 设备状态一致性：温度数据随时间缓慢变化，符合室内外温差及空调运行后的降温趋势；门窗传感器仅在离家时关闭，在家活动时保持关闭（即窗户紧闭），无异常开启记录。"

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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭晨间起床、离家及晚间归家活动模式。",
  "reasoning": [
    "1. **晨间活动分析 (06:00 - 07:30)**: 06:08 主卧灯亮起，随后主卧、儿童房、主卫等区域陆续出现人员占用信号（Occupancy=1），符合家庭成员依次起床的规律。07:19 前门关闭并手动上锁（LockOperation Type 0），且玄关/入口传感器在07:24和07:54再次触发，表明有人出门或在家门口短暂停留后离开，逻辑连贯。",
    "2. **日间状态分析 (08:00 - 16:30)**: 客厅温度传感器持续上报数据，但无占用信号，且温度随环境自然变化（从25°C升至25.4°C再降至23.8°C），符合白天无人居住时的自然温控特征。无异常设备操作。",
    "3. **晚间归家分析 (17:30 - 19:04)**: 17:30 入口占用传感器触发，随后18:14 门锁执行解锁操作（LockOperation Type 1），紧接着客厅灯光开启（18:14）及客厅占用传感器激活（18:19），这是典型的回家开门开灯流程。后续厨房灯开启（18:35）及餐厅/卧室占用信号增加，符合晚餐及晚间休息准备的行为模式。",
    "4. **排除误报**: 虽然存在多次开关灯和传感器触发，但时间间隔合理，且与人员移动路径（如从入口到客厅，再到厨房/餐厅）一致。未发现强行开锁、长时间无人却高能耗运行、或火灾/漏水等危险信号。"
  ],
  "key_evidence": [
    "07:19 front_door_lock LockOperation(LockOperationType=0) 配合 entrance_occupancy 变化，确认为正常离家行为。",
    "18:14 front_door_lock LockOperation(LockOperationType=1) 配合 living_room_light_1 开启，确认为正常归家行为。",
    "全天各房间占用传感器(Occupancy)与灯光控制(OnOff)的时间序列高度相关，符合人类活动逻辑。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则监控，确保门锁日志与物理开合状态一致即可。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "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": [
    "正常样本晚间有共享公共区域活动；异常样本只表现为早晚完全割裂。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭晚间活动模式。",
  "reasoning": [
    "1. **人员活动轨迹正常**：日志显示家庭成员在傍晚至夜间（17:30-19:10）陆续出现在餐厅、儿童房、主卧和玄关，符合下班回家后的日常作息。客厅 occupancy 传感器在 18:36 和 18:56 检测到有人，与灯光开启行为一致。",
    "2. **烹饪行为受控且无风险**：厨房灶具 (kitchen_cook_surface) 在 18:50 开启，随后厨房灯 (kitchen_light) 在 18:35 已开启（可能为预备或误触，但后续有实际使用）。关键的是，烟雾报警器 (smoke_co_alarm) 在整个时间段内未触发任何报警事件，表明没有产生过量烟雾或火灾风险。",
    "3. **安防状态正常**：入户门在 07:33 被手动解锁（出门），在 18:16 被手动上锁（回家），符合常规出入逻辑。门窗传感器状态稳定，未见异常开启或长时间未关闭的情况。",
    "4. **设备状态无故障迹象**：温度传感器读数随时间缓慢变化，符合室内外温差及空调运行规律（从早晨的~24°C逐渐上升至下午的高温，傍晚开空调后降至~23°C以下）。未发现传感器数值卡死、跳变或逻辑冲突。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True at 18:50:30 且 smoke_co_alarm 无报警",
    "front_door_lock LockOperation(LockOperationType=1...) at 18:16:00 (Lock)",
    "living_room_occupancy Occupancy=1 at 18:36:06 伴随 living_room_light_1 OnOff=True",
    "Temperature sensors show gradual changes consistent with AC operation and daily cycle"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议确认厨房灯在 18:35 开启是否为自动化场景的一部分，若无人则检查自动化规则以避免能源浪费。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "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": [
    "正常样本晚间有共享公共区域活动；异常样本只表现为早晚完全割裂。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常行为，日志显示为正常的家庭环境监控数据及晚间常规活动。",
  "reasoning": [
    "1.  occupancy传感器持续报告为0：从凌晨05:30到傍晚17:30，客厅、主卧、次卧、卫生间和玄关的运动传感器均持续显示Occupancy=0。这表明住户在此期间不在家（例如外出工作或上学），符合“两室一厅”家庭白天的典型生活模式，并非设备故障或人员滞留。",
    "2.  温度数据正常波动：客厅温度传感器在白天记录的温度值（约24.6°C - 25.4°C）呈现随时间缓慢上升后下降的趋势，且与其他房间（如卧室、厨房）的温度读数逻辑一致，无剧烈跳变或传感器卡死迹象。",
    "3.  晚间活动符合常理：18:30客厅灯开启，18:35厨房灯开启，这通常对应住户下班回家后的晚餐准备或休闲活动。此时段之前长时间无活动，与之前的离家状态衔接自然。",
    "4.  无其他危险信号：日志中未出现烟雾报警、漏水检测、门锁异常开启或灶具长时间无人看管等高风险事件。"
  ],
  "key_evidence": [
    "所有房间运动传感器在05:30-17:30期间持续为0，表明房屋空置。",
    "18:30 living_room_light_1 和 18:35 kitchen_light 相继开启，符合晚间归家场景。",
    "温度传感器数值变化平缓，无异常极值。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "可继续监控晚间厨房灯光关闭时间及是否有灶具使用日志，以确认烹饪活动是否有人看管。"

  "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（25°C+），且与住户行为模式（无人居住）及后续正常数据存在巨大矛盾。",
  "reasoning": [
    "推理步骤 1: 分析时间窗口 05:30 至 08:40，日志显示 living_room_temp_sensor 的 MeasuredValue 持续在 2445 至 2545 之间波动。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该数值对应 24.45°C 至 25.45°C。",
    "推理步骤 2: 结合上下文环境，此时段为清晨至上午，且 occupancy_sensor 多次报告 Occupancy = 0（无人）。虽然夏季室温可能较高，但连续数小时维持在 25°C 以上且无空调运行记录（日志中未见 air_conditioner 状态变化或设定值），对于有窗户和通风的两室一厅住宅而言，属于非典型的高温状态，尤其是考虑到傍晚 16:50 后温度骤降至 23.6°C 左右。",
    "推理步骤 3: 对比傍晚数据（16:50-17:40），温度稳定在 23.3°C - 23.7°C 区间，这与清晨的数据形成了巨大的、不合理的阶梯式差异。这种在同一室内环境下，短时间内出现如此剧烈的温差（超过 2°C 且持续数小时），而没有任何热源（如烹饪、人员聚集）或设备开启（空调未开）的记录，极大概率是传感器硬件故障、校准漂移或被恶意篡改，而非真实环境温度变化。",
    "推理步骤 4: 厨房温度传感器在同一时段也出现了类似的异常偏高趋势（2473 -> 2532），进一步佐证了可能是整个温控系统或特定传感器组出现了系统性故障或攻击，导致误报高温，可能触发不必要的警报或影响自动化逻辑。"

    "同一房间在 16:50 后的读数迅速回落至 23.6°C 左右的正常范围，显示出明显的不连续性。",
    "厨房温度传感器在同一异常时段内也同步表现出异常升高的趋势，排除了单一局部热源的可能性。"

  "recommended_actions": [
    "立即检查客厅和厨房的温度传感器硬件连接及供电情况，排除接触不良导致的读数错误。",
