## 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": [

    "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": "客厅温度传感器在无人居住期间出现持续且异常的升温漂移，数值远超正常环境温度范围，疑似设备故障或校准失效。",
  "reasoning": [
    "推理步骤 1: 分析时间线与 occupancy 状态。日志显示从 00:30 到 08:31 之间，所有房间（包括 living_room）的 OccupancySensing.Occupancy 均为 0，表明此时段内无人在家。",
    "推理步骤 2: 检查温度变化趋势。在无人状态下，客厅温度从 00:30 的 22.75°C (2275mK) 持续上升至 03:55 的 23.99°C (2399mK)，并在后续时段继续波动上升。虽然绝对温差不大，但结合 Matter 协议中常见的毫开尔文 (mK) 单位，需确认是否为单位误解或真实高温。若单位为 mK，则 2275mK = 22.75°C，这是合理的室温。然而，观察数据点：00:30 (22.75) -> 03:55 (23.99)。这是一个缓慢上升的过程。",
    "推理步骤 3: 重新评估异常模式。对于独居老人家庭，夜间至清晨（00:00-08:00）是高风险时段。虽然 22°C 到 24°C 本身不是火灾温度，但传感器读数在无人情况下呈现非自然的线性/阶梯式上升趋势（例如 02:10 到 03:55 间持续增加），而卧室和厨房温度相对稳定或变化较小（卧室维持在 22°C 左右）。这种‘唯独客厅传感器持续报高’且与空调/窗户状态（未提供关闭指令，但通常夜间应恒温）不符的行为，符合 sensor_drift（传感器漂移）或 sensor_malfunction（传感器故障）的特征。更关键的是，如果该传感器实际报告的是绝对温度而非相对值，或者存在固件 bug 导致数值随时间累积误差，这将构成安全隐患。考虑到用户背景为独居老人，任何不可靠的环境感知都可能导致误判（如误以为安全而忽略真实危险，或因错误温控导致过热/过冷）。",
    "修正推理步骤 3 (基于更严格的异常检测): 再次审视数据，发现一个更显著的异常点：在 02:10 到 03:55 期间，客厅温度从 23.40 上升到 23.99，同时灯光有频繁开关（02:10 开，02:12 关，02:14 开，02:16 关）。在完全无人（occupancy=0）的情况下，灯光频繁闪烁极不寻常，这通常是人为操作或自动化逻辑错误。如果是人为操作，为何在凌晨 2 点多且无人时发生？如果是自动化逻辑，为何没有触发其他联动？此外，温度读数在 03:55 达到峰值后并未回落，反而在白天（08:31 灯开）之前一直维持高位。最可疑的是**灯光在无人状态下的异常频繁切换**以及**温度读数的非自然波动**。这表明传感器可能受到了干扰，或者控制逻辑出现了严重故障（actuator_stuck 或 logic_error），进而导致对环境的误判。但在给定的 threat_type 列表中，'sensor_drift' 最能解释温度读数的持续偏差和不可预测性。",
    "最终确认：核心异常在于‘无人状态下的环境参数持续异常变化’。特别是温度传感器在没有热源（无人、无活动）的情况下，读数表现出持续的漂移趋势，不符合热力学平衡规律，属于典型的 sensor_drift 或 sensor_malfunction。"
  ],

    "在此期间，living_room_temp_sensor 读数从 2275 持续上升至 2399，呈现非自然的单向漂移趋势，而同一时间段内 bedroom 和 kitchen 温度保持相对稳定。",
    "在 02:10 至 02:16 期间，living_room_light 在无人状态下发生了多次快速开关（On->Off->On->Off），行为不符合常理。"

## 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",

  ],
  "recommended_actions": [
    "建议措施1",

}
```

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。

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",

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。

    "3. **门锁与出入记录**：07:00 左右入户门有解锁和上锁操作，结合玄关运动传感器在 07:00:09 检测到有人（Occupancy=1），这极有可能是老人在完成晨间活动后出门散步或买菜，或者是刚回家（但结合前序卧室/厨房活动，更倾向于出门）。整个过程有明确的物理动作触发，非非法入侵特征。",
    "4. **健康与安全指标**：未检测到烟雾报警、漏水报警或一氧化碳报警。厨房灶具使用后已关闭，无火灾或燃气泄漏风险。所有生命体征相关的间接证据（如长时间静止不动导致的跌倒风险）在此短窗口期内未出现异常（如长时间无活动后突然消失等）。"

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。

Chosen response:

  "threat_type": "none",
  "threat_description": "日志显示独居老人在清晨时段正常起床、进行洗漱和烹饪活动，随后出门并锁门，所有设备状态变化符合正常的日常生活行为模式，未发现安全威胁。",
  "reasoning": [
    "1. **作息规律性分析**：日志时间集中在 05:26 至 07:02，符合老年人早起的生活习惯。卧室灯在 05:26 开启，随后卫生间灯在 05:45 开启（洗漱），厨房灯在 06:05 开启（准备早餐），这一系列动作连贯且符合逻辑。",
    "2. **烹饪安全性评估**：厨房灶具 (cook_surface) 在 06:05 开启，于 06:26 关闭，持续约 21 分钟。在此期间，厨房运动传感器 (kitchen_occupancy) 始终为 1（有人），表明老人一直在厨房内照看，不存在无人看管导致的火灾风险 (unattended_cooking)。",
    "3. **离家与安防确认**：07:02 左右，入户门锁执行了上锁操作 (LockState=2)，紧接着门磁传感器显示门关闭 (StateValue=False)，随后玄关运动传感器检测到有人经过 (Occupancy=1) 并离开区域。这构成了完整的“起床-洗漱-做饭-离家”闭环，且离家时正确执行了锁门动作，无入侵或遗忘锁门迹象。",
    "4. **排除异常指标**：虽然客厅温度传感器数值较高（约 24-25°C），但这是环境温度读数，且在合理范围内波动；未检测到烟雾报警或一氧化碳报警触发；无长时间静止不动（跌倒风险）或异常的水流泄漏信号。"
  ],
  "key_evidence": [
    "06:05 kitchen_cook_surface OnOff=True 与 06:26 Off 之间，kitchen_occupancy 持续为 1，证明烹饪过程有人看护。",
    "07:02 front_door_lock LockState=2 (Locked) 后紧跟 front_door_contact StateValue=False (Closed)，确认用户已安全离家并锁好门窗。",
    "05:26 bedroom_light On -> 05:45 bathroom_light On -> 06:05 kitchen_light On 的行为序列符合典型的晨间例行活动。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控日常活动模式，若未来出现类似时间段无活动记录或长时间未锁门，需进一步核查。"
  ]
}
```

Rejected response:
{
  "is_anomaly": true,

  "threat_description": "这些变化表明存在安全异常。",

  ],
  "key_evidence": [
    "正常样本是早起单次开关灯；异常样本在深夜短时反复切换。"
  ],
  "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
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:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为独居老人在清晨正常的起床、洗漱及短暂外出活动模式。",
  "reasoning": [
    "1. **活动时间与行为逻辑符合常理**：日志时间集中在 05:30 至 07:00，这是老年人常见的早起时间段。老人先在卧室/卫生间活动（05:30-06:00），随后进入厨房准备早餐或饮水（06:07 开灯，06:08 灶具开启），最后于 06:56 出门并锁门，整体动线连贯且合理。",
    "2. **烹饪行为受控且无风险**：厨房灶具在 06:08 开启，但在 06:36 关闭，持续时间约 28 分钟。在此期间，厨房运动传感器持续报告有人（Occupancy=1），表明老人一直在厨房看护，不存在无人看管导致的火灾风险（unattended_cooking）。",
    "3. **门锁操作正常**：06:56 发生的门锁事件序列（解锁 -> 开门 -> 关门 -> 上锁）是典型的“离家”动作。虽然短时间内有两次 LockOperation 事件，但结合 DoorLockState 从 2 (Unlocked) 变为 1 (Locked) 以及 Contact Sensor 的状态变化，这符合手动出门并反锁门的正常行为，而非故障或入侵尝试。",
    "4. **环境数据稳定**：温度传感器读数随时间缓慢上升（从 ~24.3°C 升至 ~25.1°C），符合夏季清晨室内温度自然升高的规律，无剧烈波动或传感器故障迹象。"
  ],
  "key_evidence": [
    "06:07-06:36 期间 kitchen_occupancy 持续为 1，且 cook_surface 开启后不久即关闭，证明有人在旁看护。",
    "06:56 的 door_lock 状态变化序列（Unlock -> Open -> Close -> Lock）完整对应了一次正常的离家出门行为。",
    "05:30-06:00 期间 bedroom/bathroom 的活动先于 kitchen，符合起床洗漱后去厨房的生活习惯。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议保持现有监控配置，确保护士或家属能定期查看此类日常日志以确认老人健康状态（如每日按时起床）。"
  ]
}
```

Rejected response:
{
  "is_anomaly": true,

    "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。"

    "正常样本是早起单次开关灯；异常样本在深夜短时反复切换。"
