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",

    "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。

Rejected response:

  "threat_description": "入户门锁在连续三次按键输入失败后，最终通过手动操作成功解锁并开门，随后系统自动开启客厅灯光和空调，表明门锁存在故障或用户遭遇了多次尝试失败的异常事件。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-07-14T18:05:00 至 18:07:00 期间，front_door_lock 连续记录了三次 LockOperationError(source=Keypad) 事件，这表明有人（可能是家庭成员或入侵者）正在尝试使用键盘密码开锁但均告失败。",
    "推理步骤 2: 紧接着在 18:08:00，门锁状态变为 Locked (Type=1)，随后立即被手动解锁 (LockOperationType=1, OperationSource=Manual) 且 DoorState 变为 Unlocked (2)。这种‘多次失败 -> 手动成功’的模式通常意味着内部人员忘记了密码、锁具卡死需要物理干预，或者外部人员尝试了错误密码后由内部人员处理。",
    "推理步骤 3: 门锁打开后 (18:08:02)，系统逻辑触发了联动动作：living_room_light 和 living_room_ac 自动开启。虽然这可能是预设的‘回家模式’，但在经历了三次明显的认证失败后，该行为加剧了事件的异常性，提示可能存在非预期的访问尝试或设备本身的机械/电子故障导致无法一次解锁。",
    "推理步骤 4: 结合上下文，儿童房 (kids_room) 在此时间段内一直有人活动 (Occupancy=1)，且温度传感器读数正常，排除了火灾或漏水等环境威胁，焦点集中在门锁的安全性和可用性上。"

## 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。

    "推理步骤 2: 关键证据在于 occupancy 传感器状态。从 T22:30:00 到 T23:20:00，以及随后的 T23:30:00、T23:40:00 等时间点，kids_room_occupancy、living_room_occupancy、dining_room_occupancy、master_bedroom_occupancy、second_bedroom_occupancy、entrance_occupancy 均报告为 0（无人）。这表明整个房屋内没有住户活动。",
    "推理步骤 3: 在确认全屋无人的情况下，灶具被激活属于典型的‘无人烹饪’场景。此外，厨房温度传感器读数在事件发生后持续上升（从 2242 升至 2275），进一步证实了热源的存在且无人干预关闭，构成了极高的火灾隐患。"

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。

## 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",

  ],
  "recommended_actions": [

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。

  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且温度持续下降期间，阳台门被打开并开启灯光，随后儿童房内出现人员活动迹象。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，从 14:30 到 16:10，儿童房 (kids_room) 的运动传感器持续报告无人在场 (Occupancy=0)，同时该房间温度呈现明显的持续下降趋势（从 2450mK/24.5°C 降至 2343mK/23.43°C），表明房间处于空置且未受干扰的冷却状态。",
    "推理步骤 2: 关键异常事件发生在 16:14，此时所有主要生活区域（客厅、主卧等）均无人，但阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开），紧接着 16:15 阳台灯被点亮。这通常意味着有人进入了阳台区域。",
    "推理步骤 3: 最关键的证据出现在 16:10，就在阳台门打开之前，儿童房运动传感器突然报告 Occupancy=1。结合此前长达 2.5 小时的无人记录，这种‘突然出现’的人员活动极不自然，强烈暗示有外部人员通过阳台进入室内，并在儿童房内进行了短暂活动或停留后离开，随后又打开了阳台门。"

    "儿童房温度在 16:10 之后并未因人员进入而立即回升，反而继续缓慢下降，直到 17:30 才停止上报，可能意味着入侵者离开后房间重新封闭或传感器逻辑变化。"

  "recommended_actions": [
    "立即通知住户或安保人员检查儿童房及阳台区域，确认是否有外人闯入痕迹。",
    "调取家庭摄像头（如有覆盖阳台和儿童房）的视频录像进行人工复核。",
    "检查入户门锁状态，确认是否仅通过阳台进入，评估整体安防漏洞。",
    "建议重置相关传感器以排除误报可能，并加强夜间或离家时的安防监控设置。"

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。

  "threat_description": "入户门锁在正常开门后出现连续多次按键操作错误，且伴随门状态异常，疑似锁具故障或遭受暴力破解尝试。",
  "reasoning": [
    "推理步骤 1: 在 18:04:00，用户手动执行了开锁操作 (LockOperationType=1)，随后门接触传感器立即报告门已打开 (StateValue=False)，这表明物理开门动作是成功的，住户进入了室内。",
    "推理步骤 2: 紧接着在 18:05:00 至 18:07:00 期间，门锁连续三次报告 'LockOperationError(source=Keypad)'。这种在短时间内针对同一设备（Keypad）的重复失败尝试，不符合正常的家庭使用习惯（如误触一次通常不会立即重试三次）。",
    "推理步骤 3: 结合上下文，住户刚刚进入家中并开启了客厅灯光和空调，此时门锁却持续报错。这极有可能是两种情况之一：一是门锁硬件/固件存在严重故障（actuator_stuck 或 lock_malfunction），导致无法正确响应后续指令；二是有人试图利用刚输入的密码进行尾随入侵或暴力破解，但鉴于住户已在室内且无其他异常活动迹象，设备自身故障的可能性略高，但仍需警惕外部攻击风险。",
    "推理步骤 4: 虽然儿童房温度读数较高（约 23°C+），但这属于夏季正常室温范围，且与运动传感器检测到的有人活动一致，因此排除 sensor_drift 或 child_safety 威胁。核心异常集中在门锁的连续错误事件上。"

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。

Chosen response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "家长睡后儿童使用厨房电器",
  "reasoning": [
    "推理步骤1: 深夜厨房灯和灶具被打开",
    "推理步骤2: 儿童房活动状态变化",
    "推理步骤3: 缺乏成人陪同上下文"
  ],
  "key_evidence": [
    "深夜厨房灯和灶具被打开",
    "儿童房活动状态变化",
    "缺乏成人陪同上下文"
  ],
  "recommended_actions": [
    "按儿童厨房危险行为处理，建议立即干预。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，包括烹饪、儿童房有人及住户正常出入，未发现安全威胁。",
  "reasoning": [
    "时间线分析：日志从清晨 (06:48) 开始记录厨房开启灶具和灯光，随后在 07:03 关闭灶具，符合早晨准备早餐或简单烹饪的正常行为。",
    "儿童房状态：儿童房运动传感器在白天 (08:17) 检测到有人，并在傍晚至深夜 (20:54 - 23:20) 持续报告有人 (Occupancy=1)，这与跨天摘要中 kids_room 的高计数 (234) 一致，表明孩子在家且活动正常，无长时间无人导致的异常风险。",
    "夜间活动逻辑：晚上 22:31 左右，入户门被打开并手动上锁 (LockOperationType=0, OperationSource=Manual)，随后客厅、主卧等区域陆续检测到人员移动，这是典型的住户回家场景。温度传感器读数稳定在 22-23°C 之间，无火灾或过热迹象。",
    "设备行为一致性：厨房灯和灶具的开关操作时间间隔合理（如 18:25 开灯，18:25:30 开灶），且最后一条日志 (23:25) 再次开启厨房设备，可能是晚饭后清理或准备夜宵，属于正常家庭作息，未出现未看管烹饪过久或传感器数据漂移等异常。"
  ],
  "key_evidence": [
    "front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) 于 22:44:26 发生，确认是住户主动关门上锁。",
    "kids_room_occupancy 在 20:54 至 23:20 期间持续为 1，与跨天摘要中的高活跃度相符，排除儿童独处危险或入侵者进入儿童房的可能性。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持对儿童房运动传感器的监控，确保夜间无人时自动关闭相关电器。"
