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
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

  "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。

    "分析08:02-08:03的时间段：门锁状态在2分钟内从锁定变为解锁再变回锁定，且期间无门磁开启记录（或记录缺失/延迟），这通常对应于住户短暂返回取物、检查门窗后重新上锁，或者是智能锁的自动重锁功能触发，属于正常生活行为。",
    "分析18:07和21:46的时间段：18:07为下班回家时间，执行了上锁操作（可能是进门后手动上锁）；21:46为晚间，门磁显示门打开（可能有人进出或通风），随即门锁被手动上锁。这些时间点与常规作息相符，且所有操作均有对应的物理状态变化支持，无异常入侵迹象。"
  ],
  "key_evidence": [
    "07:28:19-07:28:27: 完整的‘解锁-开门-上锁’序列，对应出门行为。",

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。

## 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",

```

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。

    "1. 门锁与门禁状态分析：06:58 和 08:37 的门锁操作（LockState=2 表示已锁定）结合接触传感器（Contact Sensor）的状态变化，符合老人早晨起床后检查门锁或短暂外出/归来的正常行为模式。特别是 06:58 的序列（开锁->关门->关锁）可能是晨起确认或取快递等常规动作，且随后长时间无异常入侵迹象。",
    "2. 人员活动轨迹合理性：从 09:57 开始，客厅、玄关、厨房、卧室等多个区域的活动传感器（Occupancy Sensor）陆续被触发，且持续时间较长（如 12:27-14:25 期间多处持续有人）。这符合老人在白天进行日常起居、做饭、休息等活动的时间规律，不存在长时间静止不动导致的‘可能跌倒’或‘异常不活跃’警报。",
    "3. 环境数据稳定性：温度传感器读数在合理范围内波动（约 23-25°C），无剧烈跳变，表明传感器工作正常，无漂移或故障。光照和窗帘控制（13:56 开窗帘，14:06 开灯）也符合日间自然光不足时的自动或手动补光逻辑。",
    "4. 无危险设备告警：日志中未出现烟雾报警器、一氧化碳报警器或漏水传感器的触发记录，厨房灶具虽在 13:15 和 13:55 有 occupancy 记录，但未见超时未关闭或高温异常关联事件，且老人全程处于家中其他区域活动，属于正常的烹饪或准备餐食场景。"

    "全天多个房间（客厅、厨房、卧室、玄关）的人员存在传感器（Occupancy）持续激活，证明住户清醒且活动正常。",
    "温度数据稳定，无极端值；无烟雾、漏水、CO 报警事件。"
  ],

## 任务
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

请按以下 JSON 格式回答：

```json

  "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。

    "3. 傍晚回家行为正常：14:05 门锁状态变为解锁（LockState=2，注：Matter协议中LockState=2通常表示Unlocked/Latched，即门已开或可开启，结合后续事件看是开门进入），紧接着玄关灯亮起（OnOff=True）且客厅运动传感器被触发（Occupancy=1），这是典型的住户回家开灯并进入室内的行为序列。",
    "4. 无异常并发或冲突：没有发现门锁在有人在内时非法开启、长时间未关门、或非正常时间的入侵迹象。所有设备状态变化之间存在合理的时间间隔和逻辑关联。"

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: ..."
  ],
  "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模式，所有设备活动符合正常的家庭作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：连续三天（7月6日-8日）的日志显示，住户在清晨05:00-06:30期间主要在卧室活动（主卧传感器激活、主卧床灯开启），随后在06:30-07:00左右进入客厅和厨房区域。这种时间序列与典型的早起上班/上学流程高度一致，无异常滞留或深夜活动迹象。",
    "2. **烹饪行为安全性**：7月8日06:42厨房灯亮起，06:53灶具关闭。虽然日志中灶具状态为False（通常表示关闭或未激活），但结合灯光开启时间短（约11分钟）且之后无烟雾报警或温度急剧升高记录，这更符合快速准备早餐或烧水的正常行为，而非无人看管的长时间烹饪风险。",
    "3. **安防设备状态正常**：入户门锁在早晨07:13和07:21左右显示锁定状态（LockState=2通常代表已锁死），且门磁传感器同时报告True（闭合/锁闭）。这表明住户离家时正确执行了上锁操作，不存在入侵或门锁故障迹象。",
    "4. **传感器数据一致性**：温度传感器读数随室外气温自然波动（清晨较低，白天逐渐上升），数值变化平滑，无突变或无效值（除个别瞬间None外，属通信延迟常见现象），排除了传感器卡死或漂移的可能性。"
  ],
  "key_evidence": [
    "连续三天早晨06:30-07:00期间，主卧 occupancy 先于客厅/厨房 occupancy 激活，符合起床后离开卧室的逻辑顺序。",
    "7月8日06:42 kitchen_light 开启至 06:53 cook_surface 关闭，时长短且无后续火灾报警，属于正常短时使用。",
    "早晨离家时段（~07:13-07:21），front_door_lock 显示 LockState=2 (Locked) 且 front_door_contact 为 True，确认门窗已安全关闭并锁定。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持当前的自动化规则设置，继续监控夜间非活跃时段的异常闯入信号。"

    "推理步骤 2: 结合 occupancy_sensor 数据，在窗户打开的时间点 (约 07:18-07:21)，living_room_occupancy 和 master_bedroom_occupancy 均显示为 0 (无人)，且随后不久 front_door_lock 解锁并开门 (07:13/07:21)，表明此时屋内无人但窗户被打开。",

    "推理步骤 4: 虽然 07:04 有 kitchen_light 开启，但 07:13 已关闭，不足以解释后续的高温趋势；且窗户在非正常时间 (清晨离家时段) 被打开是典型的安全漏洞或入侵前兆。"

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模式，日志显示为正常的家庭环境监控数据。",
  "reasoning": [
    "1. 门锁与传感器状态分析：在 14:05，入户门传感器(contact)显示关闭(False)，门锁(lock)状态为2（通常Matter协议中LockState=2表示Locked且Unlatched，即已上锁但未反锁/机械锁舌伸出，或者仅表示锁定状态）。紧接着玄关灯亮起，随后客厅 occupancy 短暂变为1后归零。这符合住户回家开门、开灯、进入室内并离开玄关区域的正常行为逻辑。没有发现非法入侵迹象（如门被强行打开或长时间未关）。",
    "2. 人员活动模式分析：全天大部分时间（00:00-15:30及晚间）所有房间的 Occupancy 传感器均报告为 0，表明家中无人或处于静默状态。仅在 14:07 左右有短暂的单人活动记录，随后恢复无人状态。这种低频、短时的活动模式在白天时段是合理的，未发现长时间静止不动导致的 'possible_fall' 或 'abnormal_inactivity' 风险，因为这是白天的典型居家或非居家状态。",
    "3. 环境数据一致性：温度传感器读数在 24°C - 25°C 之间波动，数值变化平缓且符合物理规律（例如从 2497 到 2486 等，注意 Matter 协议温度单位通常为 0.01°C，即 24.97°C 等），无突变或设备故障迹象。烟雾报警器、漏水传感器等安全设备在日志片段中未触发任何报警事件。"

    "14:07 living_room_occupancy.OccupancySensing.Occupancy = 1 (短暂有人)",
    "全时段无烟雾、漏水、一氧化碳报警信号",
    "温度数据平稳，无异常跳变"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续常规监控，确保门窗传感器电池电量充足。"
