## 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。"
  ]
}

Rejected response:
```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，随后状态异常变为未锁定（State=2），且发生在住户频繁进出期间。",
  "reasoning": [
    "推理步骤 1: 日志显示在 2026-08-17T18:05:00 时，front_door_lock 报告了 'LockOperationError(source=Keypad)'，表明用户尝试使用键盘操作失败。",
    "推理步骤 2: 紧接着在 2026-08-17T18:06:00，门锁状态变为 2 (通常代表 Unlocked/未锁定)。结合之前的错误事件，这极有可能是因为锁具故障导致无法正确执行上锁或保持锁定状态，而非用户手动打开。",
    "推理步骤 3: 虽然之后在 18:13:00 有成功的上锁操作 (LockOperationType=1)，但中间约 7 分钟的窗口期存在安全隐患。考虑到此时 entrance_occupancy 和 kids_room_occupancy 均为 1 (有人在家)，如果门锁在此期间失效，可能导致非法入侵风险增加，或者仅仅是设备本身的不稳定表现。",
    "推理步骤 4: 综合来看，门锁在关键时间点出现操作错误并伴随状态异常，属于典型的 lock_malfunction，需要立即关注以防止物理安全漏洞。"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [
    "立即检查入户门锁的物理机械结构及电池电量，排除因低电量导致的误报。",
    "建议联系专业维修人员对该门锁进行固件更新或硬件检修，确保其可靠性。",
    "在问题解决前，建议住户进出时采用手动钥匙双重确认，或暂时避免依赖电子键盘开锁。"

## 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",

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",

    "2. 门锁状态逻辑一致：16:19 入户门执行了手动上锁操作（LockState=2），随后门磁传感器显示关闭状态（False，通常代表关闭/锁定），时间顺序合理，表明是住户正常离家或关门动作，非暴力破解或非法开启。",
    "3. 温度数据属于正常波动：儿童房温度传感器在 14:30-16:15 期间读数在 23.87°C - 24.61°C 之间波动，变化幅度小且符合室内环境温度特征，无突发性高温（火灾风险）或传感器故障漂移现象。",

  "threat_description": "检测到疑似入侵行为：在儿童房有人且窗户关闭的情况下，阳台门被打开，随后入户门锁被手动解锁并开门，且客厅运动传感器随后被触发。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-07-09T16:12:00 时，阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开）。此时儿童房 (kids_room_occupancy) 仍检测到人 (Occupancy=1)，且该房间窗户传感器未报告开启，表明室内有人员活动但外部通道被打开。",
    "推理步骤 2: 紧接着在 16:19:00，入户门锁 (front_door_lock) 执行了手动解锁操作 (LockOperationType=1)，并在 16:19:02 入户门接触传感器 (front_door_contact) 变为 False（门被打开）。这种短时间内先开阳台门、再开入户门的序列不符合正常家庭内部活动逻辑（通常不会同时打开两个主要出口），更符合外部人员试图进入或尾随进入的模式。",
    "推理步骤 3: 在入户门打开后约 40 秒 (16:13:00)，客厅运动传感器 (living_room_occupancy) 从之前的 0 变为 1。考虑到入户门和阳台门均已打开，且之前客厅无人，这一运动信号极有可能是新进入者穿过玄关进入客厅所致，而非屋内原有人员的移动（因为屋内人员主要在儿童房，且若为屋内人员无需特意先开阳台门）。"

  "reasoning": [
    "推理步骤 1: 分析日志发现，从 14:30 到 15:55，kids_room_temp_sensor 连续多次上报温度值分别为 2467, 2449, 2456, 2441 等。这些数值的单位通常是 0.01°C，换算后约为 24.67°C - 24.41°C。虽然换算后的温度看似合理，但原始整数值的波动幅度（如 2467 到 2449）对于同一房间在短时间内（几分钟）的变化来说过大，且数值本身（24xx）与其他房间（如 living_room 24xx, master_bedroom 24xx）的读数格式一致，但需结合上下文判断是否为误报。",
    "推理步骤 2: 重新审视数值逻辑。如果设备协议中温度测量值是以 0.01 为单位，那么 2467 代表 24.67°C。然而，观察后续数据：14:30 (2467) -> 14:35 (2449) -> 14:40 (2456)。这种在极短时间内（5-10 分钟）出现如此大幅度的跳变（差值达 18 个单位即 0.18°C），且伴随其他房间温度相对平稳下降的趋势（客厅从 2433 降至 2392），该传感器的数据表现出明显的非物理特性（噪声过大或不稳定）。",
    "推理步骤 3: 对比跨房间数据。在同一时间戳（如 15:20），客厅、主卧、厨房的温度读数分别为 2433, 2430, 2428，变化非常平滑。唯独儿童房在 14:30-15:00 期间出现了高频且大幅度的数值震荡（2467->2449->2456->2441...）。考虑到儿童房内有人活动（occupancy=1），如果是真实的热源导致温度快速升降，通常不会呈现这种锯齿状的随机波动模式，更符合传感器校准错误、信号干扰或固件 Bug 导致的 sensor_drift/malfeature 特征。",
    "推理步骤 4: 综合判断。虽然换算后的温度值（~24.5°C）并未达到危险的高温阈值（如 >35°C），但这种数据的不稳定性属于设备层面的异常（Sensor Malfunction/Drift）。如果该传感器用于联动空调或报警，错误的波动可能导致不必要的能源浪费或误触发警报，因此判定为设备故障风险。"

## 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",

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，日志显示为正常的家庭晚间活动及烹饪行为。",
  "reasoning": [
    "1. 烹饪行为分析：厨房灶具 (kitchen_cook_surface) 在 07:05、18:24 和 19:01 多次开启，并在 19:26 关闭。结合厨房灯 (kitchen_light) 的开关状态（17:42 关，18:24 开，19:00 开），符合典型的早餐准备和晚餐烹饪习惯。灶具开启后约 2 分钟即关闭，属于正常烹饪时长，未发现长时间无人看管的异常（unattended_cooking）。",
    "2. 人员活动模式：主卧 (master_bedroom)、儿童房 (kids_room)、客厅 (living_room) 和入口 (entrance) 的运动传感器在傍晚至夜间时段（17:00-20:00）频繁触发，表明家庭成员在家中进行日常活动（如做饭、走动、休息）。这种多房间的人员流动与烹饪活动的时间线高度吻合，逻辑自洽。",
    "3. 环境与安全设备：厨房窗户传感器在 19:26 显示关闭状态（BooleanState.StateValue = False，通常代表 Closed/Secure），此时灶具已关闭，无火灾或入侵风险。温度读数在合理范围内波动（22-23°C左右，Matter协议中23xx通常对应23.x摄氏度），无极端高温报警。未检测到烟雾报警器触发或漏水传感器报警。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 开启时间较短（如 18:24-19:26 虽长但中间有间歇且伴随灯光和活动，19:01-19:26 为短时操作），且伴随 kitchen_light 开启，符合烹饪场景。",
    "多个房间运动传感器（master_bedroom, kids_room, living_room, entrance）在 17:00-20:00 期间持续活跃，证明有人看护环境。",
    "厨房窗户传感器在烹饪结束后保持关闭状态，无异常开启记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则监控，确保灶具超时自动关闭功能处于启用状态以作为双重保障。"

Rejected response:
```json
{
  "is_anomaly": true,

  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告了异常的高数值（2371），远超正常物理温度范围，且随后出现无规律的剧烈波动，表明传感器可能故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-07-07T17:00:00 时，kids_room_temp_sensor 报告的温度值为 2371。根据 Matter 协议标准及常识，温度传感器通常以 0.1°C 为单位，因此该值实际代表 237.1°C，这在家庭室内环境中是不可能的，属于明显的传感器故障或数据错误。",
    "推理步骤 2: 随后的日志显示该传感器读数在 2358、2343、2353 等高位数值间剧烈震荡，直到晚上 19:00 左右才逐渐下降至正常的 2200+ 范围（即 220°C 以上仍属异常，但趋势显示其正在尝试恢复或校准）。这种非线性的剧烈波动不符合真实热力学变化规律，进一步证实是设备硬件故障或通信干扰导致的 sensor_drift/malfunction。",
    "推理步骤 3: 虽然其他房间（如客厅、厨房）的温度读数正常（约 23°C），且 occupancy 传感器显示儿童房有人活动，排除了环境突变导致的高温可能性，确认问题仅局限于 kids_room_temp_sensor 这一单一设备的数据异常。"
  ],
  "key_evidence": [
    "2026-07-07T17:00:00 记录到 kids_room_temp_sensor 温度为 2371 (即 237.1°C)",

## 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": [
    "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。"
  ]
}

Rejected response:
```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，且随后门状态显示为打开（False），存在未授权进入或锁具故障风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-07-17T18:05:00 记录到 front_door_lock 报告了 'LockOperationError(source=Keypad)'，表明用户尝试使用键盘输入密码或代码进行解锁操作失败。",
    "推理步骤 2: 紧接着在 2026-07-17T18:05:02，front_door_contact 传感器状态变为 False（通常表示门已打开或未闭合）。结合之前的开锁错误事件，这暗示门可能被强行推开、被他人尾随进入，或者是因为锁具机械故障导致无法锁定/保持关闭状态。",
    "推理步骤 3: 虽然之后有 occupancy 传感器检测到有人进入（entrance_occupancy = 1），但考虑到开锁失败发生在开门之前，且没有看到正常的成功开锁日志紧随其后，这种‘先报错后开门’的模式高度可疑，极有可能是非法入侵尝试或严重的锁具硬件故障。"
