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": [

  ],

    "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: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在尝试通过键盘解锁时发生错误，随后门传感器状态异常翻转，且门锁状态未明确显示为已锁定，存在潜在入侵风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-19T18:05:00 记录到 front_door_lock 出现 LockOperationError(source=Keypad)，表明用户或外部人员尝试使用键盘输入密码失败，这通常是暴力破解、忘记密码或恶意攻击的前兆。",
    "推理步骤 2: 紧接着在 18:14:02，entrance_contact (front_door_contact) 状态变为 False（打开），但此时 entrance_occupancy 仍为 1（有人）。虽然这可能是住户开门，但结合前文的锁具报错，不能排除是攻击者利用错误后强行进入或系统故障导致误报。",
    "推理步骤 3: 最关键的风险点在于 18:14:00 之后，日志中多次报告 DoorLock.LockState = 2（通常代表 Unlocked/未锁定状态），直到日志结束也未见明确的重新上锁操作（LockOperationType=1）或状态变更回 Locked。如果这是住户正常进出，门锁应在关门后自动或手动上锁；若门锁因之前的错误而卡死在未锁定状态，则家庭处于完全暴露的入侵风险中。",
    "推理步骤 4: 综合来看，'键盘解锁错误' + '门开状态持续' + '缺乏后续上锁确认' 构成了典型的门锁故障或安全漏洞模式，而非简单的住户行为。"
  ],
  "key_evidence": [
    "[2026-08-19T18:05:00] front_door_lock | Event: LockOperationError(source=Keypad)",

    "[2026-08-19T18:14:02] front_door_contact | BooleanState.StateValue = False"
  ],
  "recommended_actions": [
    "立即远程检查门锁固件版本并重启设备以恢复其正常工作状态。",
    "强制要求住户物理检查门锁机械结构是否损坏，并手动测试锁舌是否能正常伸缩和上锁。",
    "暂时启用更严格的访问控制策略（如临时禁用非管理员的键盘输入权限），并通知所有家庭成员更换门锁密码。",
    "联系智能家居服务商进行硬件诊断，排查是否存在电机卡滞或电路板故障。"

## 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",

    "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": "入户门锁在尝试通过键盘解锁时发生操作错误，随后门状态变为未锁定（2），且此时门口检测到有人活动，存在极高的非法入侵或意外开门风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-23T18:05:00 时，日志显示 front_door_lock 发生了 'LockOperationError(source=Keypad)'，表明用户尝试使用钥匙盘解锁失败。",
    "推理步骤 2: 紧接着在 18:06:00，门锁状态变为 2 (通常代表 Unlocked/未锁定)，这意味着尽管有报错，门最终处于开启或未锁闭状态。",
    "推理步骤 3: 关键异常在于 18:07:00，entrance_occupancy 传感器立即报告 Occupancy = 1 (有人)。结合之前的门锁故障和门口出现人员，这极有可能是外部人员利用门锁故障进入，或者是内部人员在门锁故障后未能成功重新上锁导致门外有人闯入。考虑到这是训练片段中的唯一一次门锁报错且伴随人员进入，必须视为高优先级安全威胁。"

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",

    "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": [

  "threat_description": "入户门锁在尝试通过键盘解锁时发生错误，随后状态显示为未锁定（或锁定失败），且此时门口区域有人存在，存在极高的入侵风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-21T18:05:00 时刻，日志记录到 front_door_lock 出现 'LockOperationError(source=Keypad)' 事件，表明用户尝试使用键盘输入密码进行解锁操作但失败了。",
    "推理步骤 2: 紧接着在 18:06:00，门锁状态变为 2 (通常代表 Unlocked/未锁定)。结合之前的报错，这极有可能是因为密码错误或系统故障导致门被意外打开，或者处于无法锁定的异常状态。",
    "推理步骤 3: 关键的时间窗口分析显示，在门锁报错和状态变更期间 (18:05 - 18:07)，entrance_occupancy (入口运动传感器) 持续报告 Occupancy = 1 (有人)。这意味着在门锁失效或错误的瞬间，门口正有人停留，极大地增加了非法入侵或尾随进入的风险。",
    "推理步骤 4: 虽然之后有手动上锁操作 (18:41:00 LockOperationType=1)，但先前的故障发生在有人值守的敏感时段，属于严重的安全漏洞。"

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
{

  "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。

    "推理步骤 4: 虽然儿童房温度数据异常高（如 2394），但考虑到 Matter 协议中温度单位通常为摄氏度，该数值远超物理极限，属于典型的传感器漂移或数据溢出错误（sensor_drift/sensor_malfunction），但这属于次要问题，不影响对门锁这一关键安全事件的高置信度判断。"

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. **门锁与入口安全**：15:58 入户门（front_door_lock）执行了手动上锁操作（LockState=2），且门磁传感器（front_door_contact）状态变为 False（关闭）。这是典型的离家或居家安防动作，时间点在下午，结合其他房间有人活动的情况，属于正常的生活场景，非非法入侵。",
    "3. **设备状态与传感器数据**：温度传感器读数在 23.9°C - 24.7°C 之间波动，数值变化平缓且符合室内环境温度特征，无剧烈跳变，排除传感器故障或漂移。阳台门传感器（balcony_door_contact）在 16:12 显示关闭，与整体居家状态一致。",

  "threat_description": "检测到儿童房在无人看管状态下出现长时间高温异常，且伴随入户门被非法开启（尾随或入侵）后儿童房灯光自动开启的异常联动行为。",
  "reasoning": [
    "推理步骤 1: 温度传感器数据异常。从 14:10 到 16:10，kids_room_temp_sensor 报告的温度值在 2384-2475 之间波动。Matter 协议中温度通常以 0.1°C 为单位，因此 24xx 代表约 24.x°C。虽然数值本身看似正常室温范围，但结合上下文，需确认单位是否为毫摄氏度 (mK) 或其他缩放因子。若为 mK，则 2400mK = 24.0°C，这是正常的。然而，观察日志发现温度在 14:10 达到峰值 2475 (24.75°C)，随后缓慢下降至 2384 (23.84°C)。更关键的异常在于：如果这些数值是原始读数而非标准化后的摄氏度，或者存在传感器漂移导致读数虚高（例如实际温度远高于此），则构成风险。但在本例中，最显著的异常并非温度绝对值，而是**时间序列上的孤立性**。",
    "推理步骤 2: 人员活动与温度变化的矛盾。在 14:10 至 16:10 期间，kids_room_occupancy 持续报告为 1 (有人)，而 living_room_occupancy 和 entrance_occupancy 在大部分时间为 0。这表明有人员在儿童房内。但是，注意 15:58 发生的事件链：front_door_lock 被手动解锁并锁定 (LockState=2)，紧接着 front_door_contact 变为 False (门打开)。此时 kids_room_light 在 15:58:14 突然开启。",
    "推理步骤 3: 关键的安全逻辑冲突。通常在家庭自动化场景中，当入户门被打开且检测到外部人员进入时，系统应触发警报或通知住户，而不是仅仅打开儿童房的灯。更重要的是，查看 16:12 的 balcony_door_contact 变为 False (阳台门打开)，随后 master_bedroom_occupancy 变为 1。这暗示可能有外人通过阳台或后门进入，或者家庭成员进行了非典型的移动路径。",
    "推理步骤 4: 综合判断。真正的威胁点在于 **15:58 的入户门操作**。日志显示 `Event: LockOperation(LockOperationType=1, OperationSource=Manual)` 紧接着 `DoorLock.LockState = 2` (通常 2 表示 unlocked/open)。随后 `front_door_contact = False`。这意味着有人在 15:58 打开了前门。考虑到之前 (15:14, 15:34, 15:54) 多次记录到 `entrance_occupancy = 1` 但并未立即开门，这次开门发生在下午较晚时段。如果这是家庭成员回家，通常会伴随其他设备状态变化（如客厅灯亮、空调调整等）。但此处仅开了儿童房灯。更可疑的是，如果这是一个“入侵”场景，攻击者可能利用尾随 (tailgating) 进入，然后触发了某种自动化规则（可能是误配置或恶意脚本）打开了儿童房灯，试图掩盖行踪或测试环境。此外，儿童房温度在白天持续处于较高水平且缓慢下降，若配合 occupancy=1，说明室内热源持续存在，若无明显降温趋势（如开窗），可能存在安全隐患。",
    "修正推理：重新审视温度数据。24xx 极有可能是 0.1 度单位的整数表示，即 24.0 - 24.7 度，这在夏季是正常的。那么主要威胁必须来自**门禁事件**。15:58 前，entrance_occupancy 曾短暂为 1 (15:14, 15:34, 15:54)，但均未开门。15:58 突然开门，且之后没有看到明显的“主人回家”模式（如客厅灯开、电视开等），反而只开了儿童房灯。这种行为模式符合**尾随入侵 (Tailgating)** 或**社会工程学攻击**的特征：某人跟随他人进入，或者利用授权漏洞进入，并尝试激活特定房间的设备以混淆视听或进行侦察。同时，儿童房温度在 14:10 达到最高点后缓慢下降，如果此时房间内只有一个人（孩子），而家长不在家（master_bedroom 直到 15:13 才有人，16:13 又有人），这种单人在儿童房长时间停留且无其他活动迹象，也构成了 **child_safety** 风险（监护人缺席）。",
    "最终结论：核心威胁是 15:58 的非典型入户开门行为，结合儿童房内单人长时间滞留且缺乏正常家庭活动背景，高度疑似安全入侵或监护缺失。"

  "key_evidence": [
    "2026-07-09T15:58:00 入户门锁被手动解锁并打开 (LockState=2, Contact=False)，此前该时间点附近无其他明显的‘主人回家’设备联动（如客厅灯、电视开启）。",
    "2026-07-09T15:58:14 入户门打开后仅 14 秒，儿童房灯光突然开启 (OnOff=True)，这种特定的、孤立的设备响应不符合常规的家庭自动化逻辑。",
    "在 15:58 开门前后，儿童房一直有人 (Occupancy=1)，但主卧和客厅在大部分时间为空，显示监护人可能不在场，增加了儿童独自一人的安全风险。"

## 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": "未检测到安全威胁，日志显示为正常的家庭日常活动及环境监控数据。",
  "reasoning": [
    "1. 人员活动模式分析：日志中各房间（儿童房、主卧、客厅、玄关等）的运动传感器在下午至傍晚时段频繁触发（Occupancy=1），且伴随多个温度传感器的周期性上报。这种多房间、高频次的状态变化符合家庭成员（特别是儿童和成人）在室内正常走动、休息或进行日常活动的特征，未发现长时间无人却有人体感应的异常，也未发现深夜非法入侵迹象。",
    "2. 门锁与入口安全：入户门传感器（entrance_contact）未在日志中显示开启状态，仅记录了运动传感器被触发。唯一涉及门锁的事件是16:24的“手动上锁”操作，这通常是居民回家后的正常行为，且发生在白天/傍晚，无撬锁或异常解锁记录。",
    "3. 环境与设备状态：阳台门传感器在16:12显示关闭（False），结合其他窗户传感器未见异常开启报警，表明门窗处于安全闭合状态。温度读数在23-24摄氏度左右波动，属于舒适区间，无火灾或极端天气导致的异常高温/低温风险。",
    "4. 无关键告警：日志中未出现烟雾报警器、漏水传感器或一氧化碳报警器的触发事件，排除了火灾、水浸和气体泄漏风险。"
  ],
  "key_evidence": [
    "16:24:00 front_door_lock Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 正常的手动上锁操作",
    "全天多处 occupancy_sensor 持续触发 (如 kids_room_occupancy, living_room_occupancy)，符合居家生活规律",
    "无 smoke_co_alarm, water_leak_detector 或 door_lock 异常开启/故障日志"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续定期查看日志以维持对家庭环境的监控。"
  ]
}
```

```json
{

  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器数据严重异常，数值高达 2400+ (应为 23-25°C)，且与其他房间正常读数趋势不一致，表明传感器故障或校准错误。",
  "reasoning": [
    "推理步骤 1: 对比分析发现，同一时间段内（14:35 - 17:30），客厅、主卧、厨房等所有其他房间的温度传感器读数均在正常的 23°C - 25°C 范围内波动，符合夏季室内环境特征。",
    "推理步骤 2: 唯独 kids_room_temp_sensor 的读数持续在 2400°C 至 2458°C 之间，这远超物理可能性和设备量程，属于典型的传感器数据溢出或固件 Bug 导致的数值漂移/故障。",
    "推理步骤 3: 尽管 occupancy_sensor 显示儿童房内有人活动，但如此离谱的温度读数会导致基于温度的自动化场景（如空调控制）完全失效，若该传感器被用于安全阈值判断，将构成严重的逻辑漏洞和误报风险。"
  ],
  "key_evidence": [
    "kids_room_temp_sensor 在 14:35 报告 2458，随后多次报告 24xx 系列数值，而其他房间同期仅为 23xx 系列。",

  ],
  "recommended_actions": [
    "立即标记 kids_room_temp_sensor 为‘故障/不可信’状态，并在智能家居系统中暂时禁用其参与的任何自动化规则（如恒温控制）。",
    "通知用户检查儿童房温度传感器的硬件连接或电池电量，并安排重新校准或更换设备。",
