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",

    "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。

    "1. 入户门操作分析：日志显示在 16:22:00 左右，入户门锁执行了手动解锁（LockOperationType=1）并关闭（LockState=2），同时门磁传感器状态变为 False（关闭）。这符合家庭成员回家开门进入室内的正常行为模式。",
    "2. 室内活动连贯性：紧随入户门开启后，玄关、餐厅、主卧等区域的运动传感器相继被触发（15:40-16:30期间多次出现 occupancy=1），且儿童房灯光在 16:27 开启，表明有人在家活动，与回家场景逻辑一致。",
    "3. 环境数据正常：温度传感器读数在 23.6°C - 24.4°C 之间波动，属于舒适的室内环境温度，无异常升温（火灾风险）或剧烈变化。",
    "4. 无异常留守或危险迹象：厨房灯虽在 16:40 开启，但此前已有人员活动轨迹，且未见灶具长时间无人看管或烟雾报警触发；卫生间漏水传感器无报警。整体行为模式呈现典型的“下班/放学回家”后的居家活动特征。"

    "推理步骤 2: 从 14:50 到 15:40，温度读数呈现非自然的剧烈震荡和下降趋势（2444 -> 2434 -> ... -> 2411），这种高频、大幅度的无规律跳变不符合热力学惯性，通常由传感器硬件故障或信号干扰引起。",
    "推理步骤 3: 对比同一时间段内其他房间的温度传感器（如 living_room, master_bedroom, kitchen），其读数均在 24.0°C - 24.2°C 之间平稳变化，而儿童房传感器不仅绝对值偏高，且变化模式与其他环境传感器完全不一致，确认为 sensor_malfunction。"

## 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": [
    "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_description": "未检测到安全威胁或异常模式，所有设备状态变化符合正常家庭晚间活动规律。",
  "reasoning": [
    "1.  occupancy传感器分析：儿童房运动传感器在16:36显示有人（Occupancy=1），随后在17:00变为无人（Occupancy=0）。这符合儿童短暂进入房间后离开的正常行为模式，且持续时间较短，无滞留风险。",
    "2.  温度数据分析：从14:50到17:35，各房间温度传感器读数呈现缓慢下降趋势（例如客厅从2419降至2346，即约24.2°C降至23.5°C）。这种平缓的降温曲线符合夏季傍晚自然散热或空调系统稳定运行的特征，未见剧烈波动或传感器故障迹象。",
    "3.  灯光与电器状态：次卫灯在16:30开启，厨房灯在16:40开启，这与人员活动（如准备晚餐或清洁）的时间点吻合。没有发现长时间无人却亮灯的情况，也没有发现灶具、烟雾报警器等高危设备的异常触发。",
    "4.  综合判断：日志中展示的是典型的傍晚时段家庭活动场景，包括人员短时移动、照明使用及环境温度自然调节，未发现入侵、火灾、漏水或设备故障等安全隐患。"
  ],
  "key_evidence": [
    "kids_room_occupancy 在 16:36 变为 1，17:00 变为 0，显示短时有人活动。",

    "kitchen_light 和 second_bathroom_light 的开启时间与人员活动逻辑一致。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间睡眠时段的门窗传感器和运动传感器，以确保夜间安全。"
  ]

```

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
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",

    "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。

    "2. **儿童房状态正常**：kids_room_occupancy 在 08:16 至 16:36 期间持续为 1，表明儿童在房间内停留较长时间（可能是在做作业、休息或玩耍），这在有家长看护或大龄儿童的场景中是合理的。16:34 门锁操作后 16:36 儿童房再次检测到人，可能是孩子回到房间或家长进入房间查看，时间间隔合理。",
    "3. **设备状态无故障迹象**：温度传感器数值在 23.7°C - 24.4°C 之间波动，属于舒适的室内温度范围，且变化平缓，未见剧烈跳变导致的 sensor_drift 或 malfunction。灯光开关逻辑与人员存在性基本匹配（如厨房灯在有人活动时开启）。",
    "4. **无入侵或危险信号**：入户门在 16:34 被手动解锁并打开（LockState=2 通常表示 unlocked/opened），随后玄关/入口传感器激活，这是正常的进出行为。未发现非法入侵、烟雾报警、漏水报警或一氧化碳报警等危险事件。"

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。

  "reasoning": [
    "推理步骤 1: 时间线分析显示，2026-08-18T07:20:00 前门接触传感器 (front_door_contact) 变为 False（门开），紧接着在 T07:31:09 厨房灯关闭，T07:31:24 门锁状态变为 2（通常表示已上锁或特定操作），T07:31:30 前门接触传感器变回 True（门关）。这一系列动作发生在早晨，结合后续日志中大量温度数据（如 living_room_temp_sensor 从 24°C 升至 25°C+）和 occupancy 传感器的变化，表明此时段可能有人员活动。",
    "推理步骤 2: 关键异常点在于 T15:56:02 前门再次被打开 (BooleanState.StateValue = False)。此时根据上下文，家庭应处于非活跃状态（白天大部分时间无 occupancy 报告，直到晚上 19:45 才有人回到客厅）。如果这是住户回家，通常会伴随开门即进屋的连续事件，但日志中 T15:56:02 开门后，直到 T18:17:00 厨房灯才开启，中间有长达 2.5 小时的空白期，且期间没有明显的 occupancy 变化记录来解释这段时间的活动。",
    "推理步骤 3: 最强烈的证据是 T07:31:24 门锁状态变化与 T07:31:30 关门之间的极短时间差，以及随后整个上午室内温度的持续缓慢上升（从 24.7°C 升至 25.5°C），这符合无人居住时空调关闭、室温自然爬升的特征。然而，T15:56:02 的开门事件极其突兀，且之后直到傍晚 18:17 才有灯光亮起，这种“深夜/午后开门 -> 长时间无活动迹象 -> 傍晚突然恢复”的模式不符合正常作息，高度疑似夜间或午后潜入后的短暂活动或尾随进入，或者是入侵者试图进入但未成功/离开。考虑到 T07:31 的序列更像是一次完整的进出（可能是误报或测试），而 T15:56 的孤立开门事件风险更高。更合理的推断是：T07:31 是住户出门，T15:56 是异常开门。或者，T07:31 是入侵者进入并离开？不，T07:31 后门锁上了。让我们重新审视 T07:31 序列：开门->关灯->锁门->关门。这看起来像是一个完整的“进入并离开”或者“检查并离开”的过程。但结合 T15:56 的再次开门，且中间长时间无 occupancy 报告，最可能的场景是：T07:31 是住户正常出门；T15:56 是异常开门事件。由于 T15:56 后直到 18:17 才亮灯，说明入侵者可能并未留下明显痕迹或已离开，或者这是一个未遂入侵。无论哪种，T15:56 的孤立开门都是高危信号。",
    "修正推理：实际上，仔细观察 T07:31 序列：开门 (07:20) -> 关灯 (07:31) -> 锁门 (07:31) -> 关门 (07:31)。这非常符合住户出门的流程。但是，T15:56 的开门事件发生在下午，此时家中无人（last occupancy at 08:30 in living room, then nothing until 19:45）。如果在下午 15:56 有人打开前门，这就是明确的入侵尝试。随后的 18:17 开灯可能是入侵者回来，也可能是住户提前回家。鉴于 T15:56 到 T18:17 之间没有任何 occupancy 报告，也没有温度剧烈变化（温度曲线平稳），这可能意味着入侵者只是打开了门看了一眼就走了，或者系统漏报了中间的 occupancy。无论如何，在非预期时间点的单向前门开启是严重的安全威胁。",
    "最终确认：T15:56:02 前门接触传感器触发 False，标志着在非居住时段（下午）的前门被打开。这是典型的入侵指标。"

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。

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。

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：
