## 任务
以下是过去 2 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",
  "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": [

  "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: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [

  ]
}

Rejected response:

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",
  "threat_description": "一句话描述发现的问题或确认安全",

    "关键证据2"
  ],
  "recommended_actions": [

  "reasoning": [
    "1. 入户门状态分析：日志中 `front_door_contact` 多次显示为 `False`（通常表示门关闭/锁定），且在8月15日、16日、17日的早晨时段（06:51-10:20）均保持此状态。没有记录到门被打开（True）的事件，也没有记录到门锁异常操作。对于独居老人，长时间门处于关闭状态是安全的常态，除非有外出需求，但日志中并未出现“开门后长时间无返回”的极端情况，且其他房间传感器活跃，表明老人在家。",
    "2. 人员活动轨迹分析：三个日期中，客厅 (`living_room`)、卧室 (`bedroom`) 和厨房 (`kitchen`) 的运动传感器 (`occupancy_sensor`) 均在上午时段频繁触发（值为1）。例如，8月15日08:44至09:34期间，客厅、厨房、卧室均有活动迹象；8月16日和17日也有类似的活动分布。这种多房间、分散的活动模式符合老人在家中进行晨间洗漱、准备早餐或休息的正常生活节奏。",
    "3. 环境数据稳定性：温度传感器读数在合理范围内波动（客厅约25°C，卧室约24°C），没有出现骤升（火灾风险）或骤降（设备故障或窗户大开）的异常尖峰。烟雾报警器和漏水传感器在提供的日志片段中未触发任何警报事件。",
    "4. 综合判断：虽然重点筛选了 `front_door_contact`，但其状态始终为关闭，结合室内各区域正常的活动感知和环境数据，未发现入侵、跌倒、未关火或设备故障的迹象。"

    "连续三天早晨入户门接触传感器 (front_door_contact) 均保持 False (关闭) 状态，无非法开启记录。",
    "客厅、卧室、厨房运动传感器在上午时段持续检测到人员活动 (Occupancy=1)，符合独居老人居家作息。",

    "推理步骤 2: 结合上下文观察，这些‘门未关’事件发生时，并没有紧接着的 entrance_occupancy 从 0 变 1 再变 0 的正常进出模式，也没有 door_lock 的操作记录。相反，在门显示未关的同时或稍后，entrance_occupancy 持续保持为 1（有人），且 living_room 和 kitchen 也频繁有人活动。",
    "推理步骤 3: 考虑到住户是独居老人，正常生活场景下，如果门被打开，通常会有明确的进出轨迹（如先有玄关有人，然后客厅有人，最后门关上的反馈）。这里出现的模式更像是有人进入后，门一直处于开启或被强制保持开启状态，而系统未能检测到关门动作，或者门锁机制失效导致无法自动/手动上锁，存在极高的非法侵入风险。",
    "推理步骤 4: 对比正常日期的活动摘要，虽然房间占用率正常，但关键的安全边界（入户门）的状态异常（长期未关）与内部高频活动不匹配，符合尾随进入或强行闯入后的特征。"

## 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": [

    "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": [

  "threat_description": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在健康风险或意外滞留的可能性。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 2026-08-19T00:30 至 05:26 期间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器均持续报告 Occupancy = 0，长达约 5 小时无任何人员活动迹象。对于独居老人而言，整夜完全无活动属于极度异常的静默模式。",
    "推理步骤 2: 环境状态关联。在此期间，客厅和厨房的温度传感器读数从正常的 22.8°C (2288 mK) 持续攀升至 23.8°C - 24.0°C (2380-2404 mK)，且卧室温度也同步上升。这种全室升温通常意味着空调/暖气关闭后室温自然回升，或者有人体热源但未被检测到（即人静止不动导致运动传感器失效），结合长时间的无人移动记录，更倾向于前者（设备未运行）或后者（老人昏睡/昏迷）。",
    "推理步骤 3: 关键事件缺失。虽然 02:18 和 05:26 有卧室灯开启的记录，但这可能是定时任务、误触或短暂苏醒，无法解释为何在 02:18 到 05:26 之间长达 3 小时的黑暗与静止中没有任何其他交互（如起夜去卫生间、开灯等）。特别是 02:10 时卫生间曾短暂检测到占用（可能为宠物或误报），随后立即归零，加剧了“家中仅有一人却长期失联”的疑点。",
    "推理步骤 4: 风险评估。独居老人整夜无活动伴随环境温度变化，极有可能是老人突发疾病昏迷、跌倒无法动弹或处于深度睡眠但未醒来的危险状态。若为正常睡眠，通常会有起夜行为；若为昏迷，则需紧急干预。"
  ],
  "key_evidence": [
    "00:30 至 05:26 期间所有房间运动传感器持续报告 Occupancy=0，超过 5 小时无活动。",
    "同一时间段内，客厅和厨房温度持续上升（从 22.8°C 升至 23.8°C+），表明环境调节系统可能未工作或室内热量积聚。",
    "除 02:18 和 05:26 的灯光触发外，中间长达 3 小时无任何人为操作或移动记录。"
  ],
  "recommended_actions": [
    "立即通过智能家居语音助手或电话尝试联系住户，确认其意识状态。",
    "通知家属或紧急联系人，告知系统检测到老人整夜无活动及温度异常。",
    "建议物业或社区服务中心安排人员上门查看，排除老人发生意外（如跌倒、中风）的风险。",

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 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",
  "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:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示的行为模式符合独居老人的日常作息规律。",
  "reasoning": [
    "1. 厨房灯光开启时间分析：日志显示 kitchen_light 在 05:57、12:05、12:35、12:15 等时间点开启。虽然 05:57 较早，但结合老人独居背景，可能是晨起活动或准备早餐；中午时段的开启（12:00-12:40区间）与午餐准备及烹饪时间高度吻合，且伴随 kitchen_occupancy 传感器持续触发，表明有人在场操作，非无人看管风险。",
    "2. 人员活动轨迹合理性：客厅 (living_room) 和卧室 (bedroom) 的运动传感器在白天（10:00-14:00）频繁触发，符合老人在家休息、看电视或活动的正常行为。入户门 (entrance) 传感器仅在特定时刻短暂触发（如 11:43, 12:08），随后迅速消失，推测为短暂的开门动作（如取快递、扔垃圾或通风），并未出现长时间滞留或异常反复开关门锁的情况。",
    "3. 环境数据稳定性：温度传感器读数在合理范围内波动（客厅约 24-25°C，卧室约 24°C），无剧烈跳变或传感器故障迹象。窗户传感器在 12:39 和 12:37 显示打开状态（CurrentPositionLiftPercent100ths = 10000 通常表示完全打开或关闭，需结合具体协议定义，但此处仅发生一次，且无后续报警，视为正常通风行为）。",
    "4. 跨天一致性：对比 8月3日、4日、5日的活动摘要，各房间的活动频次（Event Counts）非常稳定（Living Room ~209, Bedroom ~243, Kitchen ~240），表明老人的生活节奏固定，没有突发的异常静止（可能跌倒）或异常活跃（可能受惊/入侵）迹象。"
  ],
  "key_evidence": [
    "kitchen_light 在 12:05-12:35 期间多次开启，且伴随 kitchen_occupancy 持续为 1，符合午餐烹饪场景。",
    "8月3日-5日各房间运动传感器触发次数高度一致，显示生活规律稳定。",
    "入户门传感器仅在短时间窗口内触发，无异常长时间开启记录。",
    "温度数据平稳，无传感器漂移或故障特征。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期校准门窗传感器，确保 'CurrentPositionLiftPercent100ths' 值含义明确，以排除因协议理解偏差导致的误判。"
