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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到烟雾报警器正在进行常规自检，属于正常维护行为，未发现真实火灾或设备故障威胁。",
  "reasoning": [
    "1. 识别关键事件：在 2026-08-25T08:00:00 至 08:05:00 期间，厨房烟雾报警器（kitchen_smoke_alarm）的 `SmokeCoAlarm.TestInProgress` 属性从 True 变为 False，且 `ContaminationState` 为 0。这表明设备正在执行内部自检程序，而非检测到了真实的烟雾或一氧化碳。",
    "2. 排除误报/真实威胁：在自检期间及前后，厨房温度传感器读数稳定在 24.7°C - 25.4°C 之间（Matter协议中通常除以100，即24.77°C等），无异常升温；灶具状态显示为关闭（False）；没有漏水或运动传感器的异常触发模式。这证实了自检是计划内的或手动触发的，环境安全。",
    "3. 结合住户行为分析：日志显示老人在早晨有正常的起床、活动轨迹（卧室->客厅->玄关->厨房），门锁操作符合日常外出或回家逻辑。整体活动模式与独居老人的日常生活规律一致，无跌倒或长时间静止等健康风险迹象。"
  ],
  "key_evidence": [
    "kitchen_smoke_alarm | SmokeCoAlarm.TestInProgress = True (08:00:00) -> False (08:05:00)",
    "kitchen_temp_sensor 温度读数稳定在 24-25°C 左右，无急剧上升",
    "kitchen_cook_surface OnOff.OnOff = False (06:23:00)，表明灶具未在使用中引发警报"
  ],
  "recommended_actions": [
    "无需采取紧急行动。",
    "建议确认该自检是否为老人主动触发或系统定时任务，若为自动触发且频率过高，可检查设备固件设置以减少不必要的打扰。"
  ]
}
```

{
  "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": [
    "正常样本是短暂自检；异常样本是污染状态跨天单向恶化。"
  ],
  "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。

  "threat_description": "检测到洗碗机启动并运行，同时厨房温度传感器读数出现异常下降，但结合时间点和设备状态判断，这极可能是由于洗碗机内部高温蒸汽排放或环境温度波动导致的正常现象，未发现安全威胁。",
  "reasoning": [
    "1. 分析核心事件：日志显示在 14:00 和 14:30，厨房洗碗机（kitchen_dishwasher）的 OperationalState 发生变化（从待机/空闲变为运行中，且设置了1800秒倒计时），并在 14:55 结束运行。这是一个明确的家电使用行为。",
    "2. 关联环境数据：在洗碗机运行期间（14:00 - 14:55），厨房温度传感器读数从约 2473 持续下降至 2441 (单位通常为厘氏度，即 24.41°C)。虽然温度呈下降趋势，但在夏季或空调环境下，这种小幅度的波动是常见的。",
    "3. 排除故障与威胁：温度下降并非急剧骤降（如火灾后的降温或极端泄漏），也未伴随烟雾报警器触发。相反，洗碗机工作时产生的热蒸汽如果短暂影响传感器，或者因为门窗开闭导致的热交换，都可能导致读数变化。更重要的是，没有证据表明有人闯入（门锁无异常）、漏水（无漏水传感器报警）或健康危机（运动传感器显示住户在卧室活动，符合下午时段的生活规律）。",
    "4. 综合判断：住户在下午启动洗碗机是正常家务行为。温度传感器的读数变化与电器运行时间高度重合，属于物理环境对电器的正常响应，而非传感器故障或外部入侵迹象。"

## 任务
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到洗碗机启动并运行，同时厨房温度持续下降，符合夏季开启空调制冷或开窗通风的正常生活场景，未发现安全威胁。",
  "reasoning": [
    "1. 分析核心设备行为：日志显示 kitchen_dishwasher 在 14:00 进入工作状态 (OperationalState=1)，并在 14:30 设置了 1800秒（30分钟）的倒计时，于 14:55 结束工作 (OperationalState=0)。这完全符合家用洗碗机标准的一个洗涤周期时长，属于正常家电使用行为。",
    "2. 分析环境数据变化：厨房温度传感器数据显示温度从 13:00 的 ~25°C 持续下降至 15:30 的 ~24.1°C。这种缓慢且持续的降温趋势通常由空调运行或自然通风引起，与洗碗机运行产生的微量热量无关，也未出现火灾所需的急剧升温。",
    "3. 分析人员活动模式：入口玄关运动传感器 (entrance_occupancy) 在 13:32、13:52、14:12、14:32、14:52、15:12 频繁触发。虽然频率较高，但结合时间间隔（约20分钟一次），这可能表示住户在门口附近徘徊、整理物品或进出多次，而非典型的入侵者快速通过。同时，卫生间和主卧 occupancy 为 0，表明其他区域无人，符合部分家庭成员在家而其他人在外或休息的场景。",
    "4. 综合判断：没有烟雾报警、漏水、门锁异常或危险气体检测信号。所有事件均在合理的生活逻辑范围内，无异常安全威胁。"
  ],
  "key_evidence": [
    "kitchen_dishwasher OperationalState 在 14:00-14:55 期间呈现标准的‘启动-运行-停止’周期，耗时55分钟（含预热/排水等），符合洗碗机工作特征。",
    "kitchen_temp_sensor 温度从 2511 (25.11°C) 线性下降至 2412 (24.12°C)，排除火灾风险。",
    "entrance_occupancy 高频触发但伴随长时间停留或间歇性活动，未检测到暴力破锁或非法入侵迹象。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "若用户觉得玄关传感器过于敏感导致误报，可调整其灵敏度或去抖动时间设置。"
  ]
}
```

{
  "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": [
    "正常样本倒计时持续减少并按时停止；异常样本长时间运行且倒计时几乎不变。"
  ],
  "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
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环境监控数据及洗碗机定时任务执行过程。",
  "reasoning": [
    "1. **设备状态分析**：重点关注的厨房洗碗机（kitchen_dishwasher）在 14:00 启动（OperationalState=1），并在 14:30 设置了 1800秒（30分钟）的倒计时，最终在 14:55 停止（OperationalState=0）。这符合标准的洗碗机运行周期逻辑，无异常中断或故障迹象。",
    "2. **人员活动模式**：入口玄关运动传感器（entrance_occupancy）在 13:00-14:40 期间多次触发（Occupancy=1），表明有人在家门口附近活动或进出，但客厅、卧室等核心休息区域的所有运动传感器均保持为 0（无人）。这种“门口有人但内部无人”的模式通常对应于住户在家门口整理物品、短暂停留或访客来访，并未发现强行闯入或长时间滞留室内的异常行为。",
    "3. **环境数据一致性**：所有房间的温度传感器读数在 24°C - 25°C 之间波动，变化平缓且符合夏季室内空调或自然通风下的正常热力学规律，未发现因火灾、设备故障导致的温度骤升或传感器漂移/卡死现象。",
    "4. **综合判断**：结合时间窗口（下午时段）、设备操作逻辑（洗碗机正常工作）和人员分布（仅玄关有活动，其余区域空置），所有事件均在正常生活行为范围内，无入侵、火灾或设备故障风险。"
  ],
  "key_evidence": [
    "kitchen_dishwasher OperationalState 从 1 变为 0，中间包含 CountdownTime 设置，符合正常洗涤流程。",
    "entrance_occupancy 间歇性为 1，而 living_room/master_bedroom/second_bedroom occupancy 持续为 0，排除非法入侵特征。",
    "全屋温度传感器数值稳定在舒适区间，无剧烈波动。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议继续监控洗碗机后续是否完成排水及烘干阶段的状态更新，以确保完整循环结束。"
  ]
}
```

{
  "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": [

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。

请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

    "2. 验证测试完成状态：日志末尾显示在 10:04:00，厨房烟雾报警器的 'TestInProgress' 变为 False，表明测试流程已正常结束。虽然客厅的日志截断在此时，但结合厨房设备的正常闭环，可推断整体测试过程是受控且成功的。",
    "3. 排除误报与故障：在此期间，没有观察到温度传感器数值异常飙升、湿度突变或其他关联的安全传感器（如水浸、门磁）触发报警。 occupancy 传感器显示家中有人活动（儿童房、玄关等），符合日常家庭环境特征，非无人值守下的突发异常。",
