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",

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

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. 人员活动轨迹一致性：日志中各房间的运动传感器(occupancy_sensor)在白天时段（08:00-11:00）频繁触发，且分布合理（卧室、厨房、客厅、玄关均有活动），表明住户处于清醒和活动状态。没有发现长时间无人活动的“异常静止”或深夜异常活动的迹象。",
    "3. 环境与安全设备状态：温度传感器读数在24-25°C左右波动，属于正常室温范围，无火灾或极端天气导致的异常高温/低温报警。烟雾报警器和水漏传感器在提供的日志片段中未触发任何告警事件。",
    "4. 设备逻辑自洽性：7月15日08:32记录了一次手动开锁(LockOperation Manual)，随后08:50门磁传感器显示关闭，时间间隔合理，符合住户出门或检查门锁的正常操作，无机械卡死或传感器失效迹象。"
  ],
  "key_evidence": [
    "7月14日06:50 front_door_contact 变为 True (开门)，但在10:20前保持关闭或无持续异常开启记录，且室内传感器显示有人活动，排除入侵可能。",
    "全天多个房间(entrance, kitchen, bedroom, living_room)的 occupancy_sensor 在日间频繁触发 Occupancy=1，证明住户健康活跃。",
    "所有 temperature_sensor 读数稳定在 2400-2550 (24-25.5°C) 之间，无剧烈跳变或超出安全阈值。",
    "7月15日08:32 出现 Manual Lock Operation，随后门磁状态正常变化，设备功能正常。"

## 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。

Chosen response:

{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示住户活动规律且环境参数正常。",
  "reasoning": [
    "1. 入户门状态分析：重点关注的 front_door_contact 在三天内均报告为 False（关闭/锁定），且没有伴随 door_lock 的异常解锁记录或 contact_sensor 的开启触发。虽然日志中多次出现 entrance_occupancy 传感器值为 1，但这通常表示玄关区域有人经过或停留（如整理鞋子、取快递等），结合入户门保持关闭的状态，符合独居老人日常居家活动的特征，而非入侵行为。",
    "2. 人员活动模式分析：跨天摘要显示各房间活跃度稳定。日志中 living_room、bedroom、kitchen 等区域的 occupancy 传感器在白天时段频繁触发，表明老人在家中活动正常。特别是早晨 08:00-10:00 期间，多个房间传感器交替激活，符合起床、洗漱、准备早餐的日常作息规律。",
    "3. 环境与设备状态分析：温度传感器读数在合理范围内波动（客厅约 25°C，卧室约 24°C），无剧烈跳变或持续高温/低温报警。厨房灶具（cook_surface）和烟雾报警器（smoke_co_alarm）在日志片段中未触发任何告警或异常状态变化，排除了火灾或未关火风险。漏水传感器也未触发警报。"
  ],
  "key_evidence": [
    "front_door_contact 连续三天保持 False，无非法开启迹象。",
    "entrance_occupancy 多次触发但伴随入户门关闭，符合居家进出或玄关停留场景。",
    "全天多房间 Occupancy 传感器活跃，证明住户处于清醒和活动状态，无长时间静止（跌倒风险低）。",
    "温度数据平稳，无极端值；关键安全设备（烟感、燃气、漏水）无异常触发。"
  ],
  "recommended_actions": [
    "无需立即干预，建议继续监控。",
    "可考虑优化玄关运动传感器的灵敏度或安装位置，以减少因非意图动作导致的误报干扰，提升日志清晰度。"
  ]
}
```

Rejected response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",

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。

Chosen response:
{
  "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: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
{
  "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": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


System:
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。

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。

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。

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 2 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。

Chosen response:
{
  "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: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
{
  "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": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
