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",
  "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，日志显示为正常的家庭晚间活动及空调制冷运行过程。",
  "reasoning": [
    "1. 温度数据解读：日志中客厅温度传感器读数在2300-2380之间波动（如2360, 2359, 2346等）。根据Matter协议标准，TemperatureMeasurement.MeasuredValue单位为厘氏度（cHundredths of a degree Celsius），即除以100后为摄氏度。因此，实际室温约为23.0°C - 23.8°C，处于舒适范围内，且呈现缓慢下降趋势，符合开启空调后的正常降温逻辑。",
    "2. 设备联动分析：18:08分入户门锁手动上锁（LockState=2），随后18:08:09客厅 occupancy 变为1，紧接着18:08:14客厅主灯亮起，18:08:24客厅空调开启并设置模式为3（通常为Cool/制冷）。这一系列动作构成了典型的‘回家’行为模式：进门、开灯、开启空调降温。",
    "3. 人员活动轨迹合理：从17:30到18:30期间，多个房间（餐厅、主卧、玄关、儿童房）的运动传感器交替触发，表明家庭成员在家中不同区域活动（如准备晚餐、休息、走动等），无长时间静止或异常入侵迹象。",
    "4. 门窗状态正常：入户门在18:08上锁后保持关闭状态（Contact Sensor False表示关闭/锁定，True表示打开，需结合具体实现，但通常LockState=2 Locked意味着门已锁好），且无反复开关的异常记录。厨房灯光在18:24和18:33亮起，符合晚餐准备场景。"
  ],
  "key_evidence": [
    "18:08:00 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) 及 LockState = 2 (Locked)",
    "18:08:24 living_room_ac | Thermostat.SystemMode = 3 (Cooling Mode)",
    "18:08:09 - 18:30 多房间 Occupancy 传感器频繁切换，显示正常的人员居家活动",
    "Temperature values ~2300-2380 (23.0-23.8°C) show stable cooling trend"
  ],
  "recommended_actions": [
    "无需采取任何安全措施，系统运行正常。",
    "建议继续监控空调能耗以优化节能策略。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",

## 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",
  "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。

    "2. **烹饪行为分析**：18:11 厨房灯亮起，18:13 灶具开启，18:24 厨房灯再次确认开启。虽然中间有短暂的时间间隔，但整体构成了完整的“准备/进行晚餐”场景。没有发现灶具长时间无人看管（如开启后数小时无移动）或烟雾报警触发的迹象。",
    "3. **人员分布与温度变化**：17:30 左右主卧有人（Occupancy=1），随后客厅和玄关也有活动。温度读数（如 2368 -> 2326）呈现缓慢下降趋势，符合夏季傍晚室内温度随时间自然变化或空调运行后的稳定过程，无剧烈异常波动。",
    "4. **设备状态一致性**：所有传感器数据（温度、占用、门窗）在时间线上逻辑自洽，没有出现传感器卡死（数值不变）、漂移（数值突变且不合理）或冲突（如门开着但有人睡觉等极端矛盾情况）。"
  ],
  "key_evidence": [
    "17:59 front_door_lock LockState = 2 (Manual Lock) 配合 17:59 living_room_occupancy = 1，表明正常归家。",

    "各房间温度传感器读数在 2300-2370 之间平稳波动，无异常跳变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，确保灶具开启超过一定时间（如30分钟）若无人移动则触发提醒，以进一步降低潜在风险。"

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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 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。"
  ],
  "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": [
    "继续监测，无需立即处置。"
  ]
}

{
  "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。"
  ]
}


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，所有设备状态变化符合正常家庭作息规律。",
  "reasoning": [
    "1. **入侵风险排除**：入户门传感器（front_door_contact）在07:38显示关闭（False），同时门锁执行了手动解锁操作（LockOperationType=0），且玄关运动传感器（entrance_occupancy）随后检测到有人进入。这符合住户早晨出门或回家的正常行为模式，无强行闯入迹象。",
    "2. **烹饪与火灾风险排除**：厨房灯（kitchen_light）在晚间开启，但日志中未出现灶具（cook_surface）被激活的记录，也未触发烟雾报警器（smoke_co_alarm）。虽然任务描述重点提及kitchen_light，但缺乏伴随的烹饪设备活动或高温/烟雾报警，因此不构成无人看管烹饪或火灾风险。",
    "3. **传感器数据合理性**：温度传感器读数（如2484-2556等）呈现随时间缓慢变化的趋势，符合室内环境温度自然波动特征，无突变或停滞现象，排除了传感器故障（sensor_stuck/malfunction）。",
    "4. **人员活动逻辑一致**：客厅、卧室的运动传感器在夜间大部分时间为0（无人），白天有间歇性活动记录，且各房间活动存在时间差（如先玄关后客厅），符合多人口家庭的正常生活轨迹，无异常静止（abnormal_inactivity）或跌倒（possible_fall）迹象。"
  ],
  "key_evidence": [
    "07:38:22 front_door_contact = False (门关闭) 配合 07:38:24 LockOperation(LockOperationType=0) (手动解锁)，表明是受控的进出行为。",
    "全天无 smoke_co_alarm 触发，且 cook_surface 无激活日志。",
    "TemperatureMeasurement.MeasuredValue 随时间平滑变化，无异常跳变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的智能家居自动化规则，确保夜间安防模式正常运行。"
  ]
}
```

{
  "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": [
    "正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"

  "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，日志显示为正常的傍晚回家及居家活动场景。",
  "reasoning": [
    "1. **入户行为分析**：18:25左右，系统记录到入户门被手动上锁（LockOperation Manual），随后玄关灯亮起，且玄关运动传感器检测到有人（Entrance Occupancy = 1）。这符合住户下班回家的正常逻辑序列。",
    "2. **室内活动轨迹**：紧随入户动作后，客厅运动传感器在18:25:17触发（Occupancy = 1），客厅主灯和落地灯相继开启，空调启动并设定为制冷模式（System Mode 3）。这表明住户进入客厅区域并进行常规的环境调节，行为连贯且合理。",
    "3. **环境数据一致性**：温度传感器读数在2300-2400之间波动（对应约23.0°C-24.0°C），处于舒适区间，且随空调开启呈现缓慢下降趋势，无异常突变或设备故障迹象。所有卧室传感器均显示无人状态，与主要活动集中在客厅的情况相符。",
    "4. **排除异常模式**：未发现非法入侵特征（如门锁异常开启、非授权时间段的闯入）、火灾风险（烟雾报警器未触发）或设备故障（传感器读数稳定，执行器响应及时）。"
