## 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": "日志显示为正常的晚间家庭活动模式，包括烹饪、清洁和人员移动，未检测到安全威胁或设备异常。",
  "reasoning": [
    "1. **烹饪行为正常**：厨房灯在17:59开启，灶具(cook_surface)在17:59开启，并在18:40关闭。这符合典型的晚餐准备流程（约40分钟），且结束后灶具已关闭，无未关火风险。",
    "2. **清洁活动正常**：洗碗机(dishwasher)在18:40启动，紧随烹饪结束时间，符合饭后清洗习惯。同时厨房窗户传感器在18:30报告关闭(False)，表明门窗处于安全闭合状态。",
    "3. **人员活动逻辑一致**：客厅运动传感器(living_room_occupancy)在16:22至18:42期间多次报告有人(1)，与灯光开启时间和烹饪/休闲活动吻合。卧室和玄关传感器报告无人(0)，符合家庭成员集中在客厅和厨房的常态分布。",
    "4. **数据完整性检查**：虽然部分温度传感器在特定时间点返回None值（如18:00和18:41的厨房温度），但这通常是由于设备上报间隔或瞬时通信丢包导致的，随后数值恢复正常，不构成传感器故障或漂移的持续证据。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True (17:59) -> False (18:40): 烹饪时长合理且已关闭。",
    "kitchen_dishwasher OnOff=True (18:40): 饭后正常启动清洁程序。",
    "living_room_occupancy=1 (16:22-18:42): 客厅持续有人活动，与灯光和电器使用同步。",
    "kitchen_window_contact=False (18:30): 窗户保持关闭，排除入侵或天气风险。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期检查温度传感器None值的频率，若频繁出现可考虑更换电池或检查网络信号。"
  ]
}
```

{
  "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": [
    "正常样本回家后有客厅/厨房过渡活动；异常样本直接进入卧室。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

## 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": [

    "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回家、开灯、开启空调及准备晚餐的家庭活动。",
  "reasoning": [
    "1. **入户与安防状态正常**：17:56 门锁执行手动解锁（LockOperationType=1），随后门磁传感器显示关闭（StateValue=False），表明住户正常开门进入并关门。18:20 门磁再次显示关闭，符合居家常态。无非法入侵迹象。",
    "2. **人员活动轨迹合理**：17:31 玄关运动传感器激活，17:56 客厅运动传感器激活，18:11/18:31 玄关再次有活动记录，结合主卧和次卧的 occupancy 变化，显示住户在客厅和卧室之间移动，符合晚间休息或活动的行为逻辑。",
    "3. **设备操作符合生活场景**：17:56 住户回家后打开客厅灯和空调（SystemMode=3 通常为制冷或制热，结合温度下降趋势推测为制冷或维持舒适温度）。18:23 厨房灯亮起，18:23:30 灶具开启，这是典型的准备晚餐行为。",
    "4. **烹饪安全性评估**：虽然灶具在 18:23 开启，但日志截止时间为 18:45，仅持续约 22 分钟。对于晚餐准备而言，这是一个非常短且合理的时长，尚未达到“无人看管烹饪”（unattended_cooking）通常定义的长时间离开阈值（通常需结合后续无活动或烟雾报警判断）。且期间厨房温度传感器读数波动（18:24 为 None，可能因高温或故障，但随即恢复），未见烟雾报警器触发。",
    "5. **环境数据一致性**：室内温度从 16:40 的 ~23.7°C 逐渐下降至 18:45 的 ~22.9°C，这与开启空调（17:56）后的降温趋势一致，设备运行正常。"

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_description": "未检测到安全威胁，日志显示为正常的夜间家庭活动及就寝准备流程。",
  "reasoning": [
    "1. **入户门操作分析**：在 22:32:28-22:32:29，入户门传感器显示开启（True），随即门锁执行了手动上锁操作（LockState=1）。结合时间（深夜）和后续无其他入侵迹象，这符合住户回家或检查门窗后反锁的正常行为模式。",
    "2. **人员活动轨迹一致性**：运动传感器数据显示，主卧、儿童房、客厅、餐厅等区域在 21:55 至 23:00 期间均有人员活动记录（Occupancy=1），且次卧和主卫在特定时段无人（Occupancy=0）。这种多房间活跃但非全 house 活跃的状态，符合家庭成员分散在家中的正常生活场景。",
    "3. **设备状态逻辑自洽**：22:32 左右，客厅灯关闭、空调关闭、主卧窗帘关闭（CurrentPositionLiftPercent100ths=10000 表示完全升起/打开？注：通常Matter中10000代表100%开，即窗帘拉开；若为遮光需求可能是误读或用户习惯，但结合灯光关闭，更可能是睡前整理环境）。这些动作与“准备休息”或“调整夜间环境”的行为一致，未发现异常的设备卡死或故障信号。",
    "4. **环境数据正常**：温度传感器读数在 22.4°C - 22.6°C 之间波动，属于舒适的室内温度范围，无剧烈跳变暗示传感器故障或火灾风险。"
  ],
  "key_evidence": [

    "Temperature readings stable around 2250 (22.5°C) - 环境温度稳定，无异常"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持常规监控，确保入户门自动上锁功能（如启用）工作正常，以增强安全性。"

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. 人员活动模式分析：22:25-23:10 期间，儿童房、主卧、餐厅、玄关和客厅的运动传感器多次触发 (Occupancy=1)。这表明家庭成员在深夜仍在进行正常的居家活动（如洗漱、休息准备、走动等），并非异常入侵或长时间静止的异常情况。",
    "3. 设备状态一致性：客厅灯和空调在 22:30 关闭，与运动传感器的活跃状态结合看，可能是住户离开客厅区域去其他房间（如卧室）休息，符合夜间作息规律。没有发现烟雾报警、漏水或门窗异常开启未关等危险信号。"

    "2. 人员活动模式分析：在21:55至23:39期间，卧室、客厅、厨房、玄关及卫生间的运动传感器频繁触发（Occupancy=1），表明住户在家中多处走动。这种多房间的活动轨迹符合老年人晚间洗漱、休息前准备或轻微活动的正常行为特征。",
    "3. 卫生间异常值澄清：虽然卫生间运动传感器在22:15、22:45、23:15显示为0（无人），但这与整体活跃模式并不矛盾。考虑到时间间隔（约30分钟一次归零），这极可能是住户短暂离开卫生间返回其他房间，或者是传感器因老人动作幅度小导致的间歇性漏报/误报，而非长时间静止不动（跌倒风险通常伴随长时间无活动且无其他区域活动，此处其他区域活动频繁）。",
    "4. 无入侵迹象：入户门传感器和门锁未在日志中报告异常开启或非法操作，所有活动均发生在室内，且时间集中在晚间，符合居家作息。"

  ],
  "recommended_actions": [
    "无需立即干预，继续保持常规监控。",

## 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",
  "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，日志显示为正常的晚间居家活动及睡眠准备过程。",
  "reasoning": [
    "1. **入户门操作正常**：22:11:38 门磁显示开启，随即门锁执行手动上锁（LockState=1），符合住户回家或检查门窗后反锁的正常行为逻辑，无非法入侵迹象。",
    "2. **人员活动轨迹合理**：客厅运动传感器在 21:59 至 23:55 期间持续检测到人（Occupancy=1），表明住户主要在客厅活动；卧室传感器在 22:11 和 22:31 短暂激活后熄灭，随后在 23:08 和 23:38 变为无人状态，符合住户在卧室短暂停留（如换衣、整理）后离开去客厅休息或准备入睡的习惯。",
    "3. **环境设备状态稳定**：空调在 22:11 关闭，随后各房间温度缓慢上升（例如客厅从 2246 升至 2277，即 22.46°C 升至 22.77°C），这是典型的夜间无主动制冷下的自然升温趋势，且数值在合理范围内，未出现异常高温或传感器故障漂移。",
    "4. **无危险设备触发**：厨房烟雾报警器、灶具、漏水传感器等关键安全设备在整个时间段内无任何报警或异常状态上报，排除火灾、燃气泄漏或水患风险。"
  ],
  "key_evidence": [
    "front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) - 确认手动上锁",
    "living_room_occupancy | OccupancySensing.Occupancy = 1 (持续存在)",
    "kitchen_smoke_co_alarm | No events reported - 无火警/气警",
    "living_room_temp_sensor | TemperatureMeasurement.MeasuredValue 缓慢上升 (22.46->22.77) - 正常热惯性表现"
  ],
  "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，确保夜间安防系统处于布防状态。"
  ]
}
```

{
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "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",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

    "4. **环境数据稳定性**：温度传感器读数在 22.4°C - 22.6°C 之间波动，变化幅度极小且符合室内热惯性规律，无突发性高温（火灾风险）或低温异常。烟雾报警器和漏水传感器无任何告警事件。"

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. 门锁状态分析：22:43左右，入户门传感器显示开启（True），随即门锁执行了手动上锁操作（LockState=1）。结合之前的运动传感器数据（entrance/living_room等均有Occupancy=1），这表明有人在家并完成了关门落锁的动作，是标准的居家安防行为，而非入侵或异常开锁。",
    "3. 设备联动与习惯分析：22:43同时触发了客厅灯关闭、空调关闭以及主卧窗帘关闭。这种多设备在同一时间点（22:43）的协同动作，强烈暗示用户正在执行“就寝模式”或“离家检查”流程，属于正常的自动化场景或手动习惯操作。",
    "4. 传感器状态一致性：运动传感器在多个房间（entrance, living_room, dining_room, master_bedroom, kids_room）持续报告 Occupancy=1，且后续多次刷新，表明家中有人活动，没有发生传感器故障（如一直为0或一直为1无变化）或信号丢失的情况。"
