## 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. **活动模式分析**：日志显示住户在每天上午10:30至下午13:30之间活跃于客厅、厨房和卧室，符合独居老人白天的常规作息（如起床、准备午餐、休息）。入户门传感器仅在特定时间点短暂触发（如11:22, 11:57），随后无持续异常开启记录，表明没有非法入侵迹象。",
    "2. **烹饪安全评估**：虽然重点关注的 kitchen_light 多次开启（05:58, 12:05, 17:05等），但厨房灶具(cook_surface)状态未在日志中显示为“开启”或高温状态，且厨房温度传感器读数稳定在24-25°C左右，未出现因长时间无人看管烹饪导致的温度急剧升高现象。因此排除 unattended_cooking 风险。",
    "3. **设备健康检查**：所有温度传感器读数在合理范围内（23-26°C），无极端值；运动传感器频繁触发与住户活动一致；唯一的一次 `kitchen_temp_sensor` 读数为 `None` (11:29) 后迅速恢复，属于正常的通信抖动或瞬时故障，不构成 sensor_malfunction 的持续性证据。"
  ],
  "key_evidence": [
    "厨房温度传感器读数稳定在24-25°C区间，无异常升温，佐证无火灾或未关火风险。",
    "入户门传感器仅在短时间窗口内触发，且伴随玄关/客厅人员活动，符合正常出入逻辑。",
    "各房间运动传感器活动轨迹连贯，未发现长时间静止后的突然活动（跌倒风险低）或完全静默（失联风险低）。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准厨房温度传感器，确保数据连续性，尽管本次波动看似正常。"
  ]
}
```

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": [

  ],
  "key_evidence": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"

## 任务
以下是过去 3 天的设备活动记录。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",

  ],
  "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。

    "1. 活动模式一致性分析：对比2026-08-08至08-10的跨天摘要数据，各房间的活动计数（如living_room约208-209次，kitchen约239-242次）保持高度稳定。这种稳定性表明住户的生活作息规律，没有突发的长时间静止（可能暗示跌倒或昏迷）或异常的剧烈活动。",
    "2. 厨房安全状态检查：虽然重点设备包含kitchen_light，但日志中并未出现灶具(cook_surface)长时间开启后无人看管的情况。相反，在08-10T11:25:00记录到灶具关闭(OnOff=False)，随后有正常的温度传感器读数恢复和人员活动，符合正常的烹饪结束流程。未发现fire_risk或unattended_cooking迹象。",
    "3. 传感器数据合理性验证：温度传感器读数（如客厅25°C左右，卧室24°C左右）处于正常舒适区间，无极端值或跳变，排除了sensor_malfunction或sensor_drift。运动传感器(Occupancy)频繁触发且与时间分布合理（白天活跃），符合独居老人在家活动的特征。",
    "4. 门窗与锁具状态：入户门传感器仅在特定时间点（如11:34, 12:14等）短暂触发，且伴随玄关灯或运动传感器的联动，推测为正常的短暂外出或取物行为，未见非法入侵(intrusion)或尾随(tailgating)的持续异常模式。"

    "所有温度传感器读数均在合理范围内（23-25°C），无硬件故障迹象。",

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",
  "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: ..."

    "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:

  "reasoning": [
    "1. 活动模式一致性分析：对比2026-08-04、05、06三天的日志，住户在早晨7:30-9:00期间活跃于厨房（kitchen_occupancy=1）和客厅（living_room_occupancy=1），随后在卧室（bedroom_occupancy=1）有短暂停留，这符合老人起床、准备早餐/洗漱、休息的常规生活节奏。三天内的时间点和活动区域高度重合，无显著偏离。",
    "2. 门锁与入侵检测：入户门传感器（front_door_contact）仅在08-06出现一次关闭状态（False），结合该时间点玄关运动传感器（entrance_occupancy）被触发，表明是住户正常出门或回家，而非非法入侵。其余时间门窗状态稳定，无异常开启记录。",
    "3. 环境与安全指标正常：所有温度传感器读数在合理范围内（约24-25°C，Matter协议中通常单位为0.01摄氏度，即24.42°C等），无极端高温提示火灾风险。烟雾报警器（smoke_co_alarm）和漏水传感器（water_leak_detector）在整个日志片段中未触发任何报警事件。",
    "4. 传感器状态健康： occupancy_sensor 的状态变化（0到1或1到0）具有明确的时间间隔和逻辑关联（如人进入房间后持续一段时间才离开），未发现传感器卡死（stuck）或数据漂移（drift）导致的异常高频跳动或长期静止不动的情况。"
  ],
  "key_evidence": [
    "连续三天早晨7:30-9:00期间，kitchen_occupancy 和 living_room_occupancy 均呈现规律的 '1' (有人) 状态，行为模式一致。",
    "08-06T08:38:02 front_door_contact 变为 False，同时 entrance_occupancy 为 1，符合正常出入行为。",
    "全时段内 smoke_co_alarm 和 water_leak_detector 无任何报警触发记录。",
    "温度读数稳定在舒适区间，无异常波动。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",

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 3 天的设备活动记录。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",

    "1. 活动模式分析：日志显示老人在上午10:30至下午14:00期间活跃，主要分布在客厅、厨房和卧室。这符合独居老人白天起床后在客厅休息、去厨房准备食物/饮水、偶尔回卧室休息的日常作息规律。",
    "2. 关键设备行为验证：厨房灯（kitchen_light）仅在特定时间点开启（如05:51, 12:05, 12:35, 12:15），且伴随厨房运动传感器（kitchen_occupancy）的激活，表明有人在使用厨房，不存在无人看管的烹饪风险或设备故障导致的常亮。",
    "3. 环境数据合理性：温度传感器读数（如2542代表25.42°C）随时间缓慢变化，符合室内环境温度自然波动特征，无剧烈跳变暗示传感器故障。门窗传感器和门锁状态虽未在片段中频繁触发异常开合，但结合运动传感器的人体存在，未发现非法入侵迹象。",
    "4. 健康与安全指标：所有房间均有运动传感器检测到人体存在，未发现长时间无活动的“abnormal_inactivity”或跌倒后的静止情况。烟雾报警器和漏水传感器无报警记录。"
  ],
  "key_evidence": [
    "厨房灯与厨房运动传感器联动正常，无长时间无人值守的烹饪场景。",

  "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. 室内活动模式一致性：客厅 (`living_room`)、厨房 (`kitchen`) 和卧室 (`bedroom`) 的运动传感器在白天时段（08:00 - 11:00+）持续报告占用状态 (`Occupancy = 1`)，表明老人在家中活跃。这种跨房间的移动轨迹（如从卧室到厨房再到客厅）符合独居老人的日常生活逻辑。",
    "3. 环境数据稳定性：温度传感器读数在合理范围内波动（约 24°C - 25.5°C），没有突变的极端值，排除了传感器故障或火灾/漏水导致的紧急环境变化。烟雾报警器和燃气报警器无任何触发记录。",
    "4. 无跌倒或长时间静止迹象：虽然这是片段日志，但在选定的时间窗口内，多个房间的运动传感器交替激活，没有出现某单一区域长时间（数小时）完全无活动而其他地方却有人活动的情况，也未发现典型的跌倒后静止特征。"

## 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: ...",

    "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。

  "threat_description": "检测到独居老人在凌晨时段（02:18 - 03:55）出现长时间无活动且室内温度异常升高的情况，存在健康风险或跌倒后无法呼救的可能。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 02:18 卧室灯开启，随后在 02:30 至 03:55 期间，所有房间（包括客厅、卧室、厨房、卫生间、玄关）的运动传感器均报告为'0'（无人），持续时长超过 1.5 小时。对于独居老人而言，深夜长时间无活动属于异常模式。",
    "推理步骤 2: 环境数据关联。在此期间，客厅和厨房的温度传感器读数从约 23°C (2300 mK) 持续上升至接近 24°C (2398 mK)，而卧室温度相对平稳但略低。这种升温可能是由于空调/暖气未关闭导致的热量积聚，或者是人员被困在某个封闭空间（如浴室或卧室角落）产生的体热效应，亦或是设备故障导致的误报，但结合无人状态，需优先排除人员滞留风险。",
    "推理步骤 3: 行为逻辑推断。虽然 02:18 有开灯动作，暗示有人起床，但随后的长时间无活动记录与独居老人的正常作息（通常夜间起夜后不久即返回睡眠或进行短暂活动）不符。若老人发生跌倒或突发疾病，长时间无移动将导致危险状况升级。此外，后续直到 05:34 才有再次开灯记录，中间间隔过长，进一步证实了该时段内缺乏有效生命体征监测。"

    "同一时间段内，客厅温度持续攀升至 23.98°C，且无任何人员活动迹象来解释热源变化。",
    "独居老人背景使得长时间无活动成为高风险指标，而非正常的深度睡眠（通常会有翻身等微小活动被部分传感器捕捉，或至少有一次明确的起床/入睡切换）。"

    "立即通过智能家居系统向老人发送语音询问或视频通话确认其安全状态。",
