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",
  "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。

  "confidence": "medium",
  "threat_type": "credential_theft",

  "threat_description": "日志显示独居老人正常的夜间睡眠模式及次日清晨起床活动，未发现入侵、异常停留或设备故障迹象。",
  "reasoning": [
    "推理步骤 1: 分析夜间时段 (00:00 - 07:00)，所有房间运动传感器持续报告无人 (Occupancy=0)，且温度数据稳定在正常居住范围 (22-23°C)，表明住户处于正常的睡眠状态，无异常闯入或长时间滞留。",
    "推理步骤 2: 检查关键事件序列，02:11 门锁解锁和开门后，玄关灯自动亮起 (符合预设自动化逻辑)，随后客厅在 02:13 检测到有人进入，这与住户起夜如厕或短暂活动的行为一致；02:30 后全屋再次恢复无人状态，符合入睡后的常规作息。",
    "推理步骤 3: 验证白日活动，07:09 的开门记录伴随完整的‘锁闭->开门->关门->上锁’操作序列，且后续有规律的日间活动记录，20:46 的关门上锁操作也符合正常回家流程，整体行为模式与独居老人的生活习惯高度吻合。"
  ],
  "key_evidence": [
    "00:00 至 07:00 期间所有房间 Occupancy 均为 0，且温度读数连续且合理。",
    "02:11 门锁开启后，玄关灯立即点亮，随后客厅检测到人员，形成连贯的‘起夜’行为链。",
    "07:09 和 20:46 的门锁操作均包含完整的锁定/解锁循环，无异常强制开锁或长时间未锁门情况。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查老人卧室和卫生间的温湿度传感器校准情况，确保夜间环境舒适安全。"

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

  "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": "客厅温度传感器读数严重偏离物理现实，显示异常高温（2300-2400+），且与 occupancy 状态及跨天数据趋势不符，疑似传感器故障或漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 living_room_temp_sensor 在凌晨时段（01:40 - 04:50）报告的温度值高达 2300-2426。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该数值换算后为 23.00°C 至 24.26°C，看似正常；但对比同一时间段其他房间（如 second_bedroom、master_bedroom）的读数（约 23.3-24.1°C）以及白天/晚上的常规波动范围，需进一步确认单位。然而，仔细观察跨天摘要中的设备事件计数（living_room=116 vs kitchen=11），结合日志中 temperature 事件的密集程度和数值的‘跳跃’感（例如从 2322 到 2334 再到 2348），若假设原始数据未做单位缩放或存在特定编码错误，这些数值（2300+）相对于环境温度而言过高。更关键的异常在于：如果这些数值代表毫摄氏度（mCelsius），则 2400 mC = 2.4°C，这在夏季夜晚对于有空调或自然通风的室内极不可能；如果代表摄氏度，则 24°C 是合理的。",
    "推理步骤 2: 重新审视数据模式。注意日志中 `living_room_occupancy` 在 02:30, 03:30, 04:30 多次报告为 0（无人），但在 03:14 和 03:15 突然变为 1（有人）。与此同时，温度传感器在无人状态下持续上升并维持在高位（23xx -> 24xx）。如果这是真实的室温升高，通常需要热源。但在凌晨 3 点，全屋大部分区域（entrance, bathroom, master_bedroom occupancy 均为 0）处于静止状态。",
    "推理步骤 3: 核心矛盾点在于数值的‘量级’与‘行为’的不匹配。虽然 2300-2400 可能是 23.0-24.0°C 的合法表示，但观察 `second_bedroom_temp_sensor` 在同一时间段的数值（2332 -> 2350 -> 2379...），其变化曲线与客厅几乎完全同步且平行。这种高度相关的异常升温发生在所有卧室和客厅，而厨房温度也同步上升。最可能的解释并非真实的热源导致全屋同时升温，而是**传感器固件将温度值错误地放大了 100 倍（即实际温度约为 23-24°C，但上报了 2300-2400）**，或者反之，如果系统期望的是整数摄氏度，那么这些数值就是错误的浮点数截断。但在安全分析语境下，这种‘全员同步异常读数’且伴随 occupancy 逻辑冲突（人在时温升快，人走时温仍高）的模式，强烈指向**Sensor Drift (传感器漂移)** 或 **Sensor Malfunction (传感器故障)**，导致环境感知失效，可能掩盖真实的火灾风险或误报空调控制。鉴于数值远超正常室温波动范围（即使按 mC 算也是 2.3°C，太低；按 C 算又太高除非极端天气），判定为传感器数据不可信。",
    "修正推理步骤 3 (基于常见 IoT 故障模式): 实际上，许多 Matter 设备在故障时会返回极大值或固定偏移值。这里 2300-2400 的数值如果是摄氏度，意味着室内达到 24 度以上的高温，这在 7 月深夜且无人员活动的情况下，若无空调开启（日志未显示 AC 开启事件，仅显示灯开关），是不符合常理的。更有可能的是，传感器发生了**漂移**，读数不再反映真实温度，或者单位解析错误。无论哪种情况，依赖此数据进行温控或火警联动都是危险的。"

  "key_evidence": [
    "living_room_temp_sensor 在凌晨无人时段（Occupancy=0）持续报告 2300-2426 的异常高值，且与其他房间温度传感器呈现非自然的同步剧烈波动。",
    "在 03:14 检测到 Occupancy=1 后，温度读数并未出现预期的因人体散热导致的微小稳定，反而继续大幅爬升，随后在 Occupancy=0 时依然维持高位，违背热力学常识。",

    "推理步骤 1: 分析日志发现，从 2026-08-19T01:40:00 开始，living_room_temp_sensor 的 MeasuredValue 数值在 2312 到 2435 之间波动。",
    "推理步骤 2: Matter 协议及智能家居标准中，温度测量值通常以 0.01°C 为单位存储（即实际温度 = 记录值 / 100）。因此，记录值 2312 代表 23.12°C，而峰值 2435 代表 24.35°C。虽然单看数值似乎合理，但需结合上下文判断。",
    "推理步骤 3: 重新审视数据模式，注意到厨房 (kitchen) 和卧室 (bedroom) 的温度传感器在同一时间段内也报告了类似的数值范围（例如 kitchen 达到 2404 -> 24.04°C，bedroom 达到 2301 -> 23.01°C）。然而，更关键的异常在于数值的**线性增长趋势**与**物理环境的不匹配**。在凌晨 01:40 至 04:50 期间，尽管 occupancy 为 0（无人），且空调未开启（日志中无 air_conditioner 状态变化），温度却呈现持续的单向上升趋势（从 23.12°C 升至 24.35°C），且厨房温度同步飙升。这种多房间、长时间、无热源介入下的同步高温爬升不符合热力学规律，极大概率是传感器固件 bug 导致的数值溢出、单位错误（如误将毫开尔文当摄氏度读取）或严重的校准漂移，而非真实环境温度升高。若按字面理解为 2300°C+，则直接判定为设备损坏/数据错误。",
    "修正推理步骤 3 (基于常见 IoT 数据陷阱): 实际上，许多廉价 Matter 设备在特定固件版本下存在单位转换错误，将内部存储的毫摄氏度 (mCelsius) 直接作为 Celsius 上报，或者反之。如果 2312 代表 23.12°C，那么 2435 代表 24.35°C，这在夏季是可能的。但是，观察 **kitchen_light** 的状态：它在 07:17 关闭，但在 19:44 和次日 07:10/03:15 开启。更重要的是，观察 **occupancy** 模式：凌晨 03:14 和 03:14 (次日) 有短暂的 Occupancy=1，随后立即变为 0。如果这是入侵者，为何没有触发其他报警？最合理的解释是：**传感器数据本身不可信**。考虑到三个房间的温度传感器几乎同时出现类似量级的“异常”高值（相对于历史基线或物理常识），且伴随时间上的严格同步性，这强烈暗示是系统层面的数据上报错误（Sensor Drift/Malfunction），导致所有温度读数虚高。特别是如果这些数值实际上是 231.2°C 或更高，那绝对是火灾风险；如果是 23.12°C 但趋势异常，则是传感器漂移。鉴于题目要求识别“可疑行为”，这种全系统性的温度读数异常属于典型的 Sensor Drift 或 Malfunction。",
    "最终确认推理: 无论单位如何，该时间段内多个房间温度传感器同时显示异常高的数值（假设单位为 °C，则 >23°C 对于深夜无人时段且无加热源的情况属于异常升温；若单位为 m°C 则完全错误）。最关键的是，这种跨设备的同步异常表明不是单一设备故障，而是数据链路或固件逻辑问题，属于 sensor_drift 或 sensor_malfunction。为了安全起见，将其归类为 sensor_drift（数据漂移/不准确），因为设备可能仍在运行但读数已失真。"

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

  "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",

  "threat_description": "独居老人在凌晨 02:13 至 02:30 期间出现异常活动模式：门锁被打开后，客厅传感器检测到有人进入，但随后在 5 分钟内该人员离开且全屋其他区域（卧室、厨房等）无后续活动迹象，伴随室内温度持续缓慢上升，疑似老人夜间起夜如厕后发生跌倒或突发疾病导致无法移动/呼救。",
  "reasoning": [
    "推理步骤 1: 时间分析 - 事件发生在凌晨 02:11-02:13，属于独居老人高风险时段（夜间）。日志显示入户门先被打开（LockState=2），紧接着玄关灯亮起，随后客厅运动传感器（living_room_occupancy）在 02:13 检测到有人（Occupancy=1）。这表明有人从外部或内部走廊进入了客厅区域。",
    "推理步骤 2: 行为模式分析 - 正常情况下，老人夜间起床会先去卫生间或厨房，然后返回卧室。然而，日志中在 02:13 检测到客厅有人后，直到 02:30（长达 17 分钟）前，卧室、厨房、卫生间的运动传感器均报告为无人（Occupancy=0）。这种‘只出现在客厅’且长时间不移动到其他房间的行为，极不符合正常起居习惯。",
    "推理步骤 3: 环境数据佐证 - 在此期间（02:15-02:30），室内温度传感器读数呈现持续上升趋势（客厅从 23.32°C 升至 23.38°C，卧室从 22.42°C 升至 22.41°C 波动后微升）。虽然温升幅度不大，但在无人活动的情况下，结合老人可能因跌倒被困在客厅角落无法回房的情况，加上没有触发烟雾报警或漏水报警，最合理的解释是老人发生了意外（如跌倒）并处于静止状态，未能进行正常的生命体征反馈或移动。",
    "推理步骤 4: 排除误报 - 06:50 和 08:34 的正常开门记录显示设备工作正常，排除了传感器故障。02:11 的开门操作来源未明确标注为自动，可能是老人自己开门，也可能是外部入侵，但考虑到后续只有老人可能出现的短暂停留特征（非入侵者通常会快速通过或寻找目标），且之后全天再无异常，更倾向于内部健康突发事件而非外部入侵。"

  "key_evidence": [

    "独居老人背景增加了夜间跌倒或突发疾病的风险权重。"
  ],
  "recommended_actions": [
    "立即联系家属或紧急联系人确认老人安全状况。",
    "建议物业或社区服务中心安排人员上门查看（若具备联动能力）。",
    "检查家中是否安装了跌倒检测摄像头或毫米波雷达，以便未来更早发现此类静止异常。",

## 任务
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。

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "credential_theft",
  "threat_description": "临时访客码在非预约时段使用",
  "reasoning": [
    "推理步骤1: 凌晨 02:11 门锁解锁并开门",
    "推理步骤2: 玄关灯随后开启",
    "推理步骤3: 紧接着出现室内活动，不像误触"
  ],
  "key_evidence": [

  "recommended_actions": [
    "标记为异常入户，建议检查临时访客码使用记录并立即重置。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的夜间离家与清晨归家模式，未发现安全威胁。",
  "reasoning": [
    "推理步骤 1: 凌晨 02:11 分检测到入户门锁解锁 (LockState=2) 且门传感器状态为开启 (False)，随后玄关灯自动亮起，这是典型的住户夜间归家或起夜开门行为。",
    "推理步骤 2: 在 02:13 分，客厅运动传感器检测到有人 (Occupancy=1)，紧接着在 02:30 分该区域 occupancy 恢复为 0，表明人员仅短暂经过客厅（如前往卧室），随后离开并锁门（虽然日志未显式记录再次上锁，但结合后续长时间无活动推断已处于安全状态）。",
    "推理步骤 3: 从 02:30 到次日 07:30，所有房间（包括入口、客厅、卧室、卫生间）的运动传感器均持续报告无人 (Occupancy=0)，符合家庭夜间睡眠/离家的正常静默模式，无异常闯入迹象。"
  ],
  "key_evidence": [
    "02:11 门锁解锁与门开事件紧随其后的是短暂的客厅有人检测，随后立即清空。",
    "02:30 至 07:30 期间，全屋关键区域运动传感器连续保持 '0' (无人) 状态超过 5 小时。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议用户确认 02:13 进入客厅的人员身份是否符合预期（例如是否为家人起夜）。"
