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：

```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",

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。

    "推理步骤 2: 关键证据在于 OccupancySensing.Occupancy 传感器状态。在灶具开启前后（23:20 - 23:30），所有房间包括厨房、客厅、餐厅及儿童房的运动传感器均报告 Occupancy = 0，表明屋内无人在场。",
    "推理步骤 3: 物理环境数据佐证了异常。从 23:20 到 23:55，厨房温度传感器读数持续上升并维持在较高水平（约 226°C 至 227°C，注：Matter 协议中温度单位通常为摄氏度乘以 10，即实际约 22.6-22.7°C，但考虑到是夜间且全屋温度稳定，此处更可能是设备误报或特定场景下的相对高温趋势；然而结合‘灶具开启’这一高危动作，最合理的推断是用户意图烹饪却未离开，或者系统逻辑判定为‘无人看管的高温源’。即便温度数值本身因单位换算看似正常，**无人操作下自动/远程开启灶具**本身就是最高级别的 unattended_cooking 威胁。若温度数值代表绝对高温（如 226 度），则直接构成 fire_risk。基于日志上下文，核心威胁在于‘无人 + 开火’的行为模式。",
    "修正推理步骤 3: 重新审视温度数据，2243-2273 的数值极有可能是 Matter 协议中的 `MeasuredValue` (单位通常是 0.1°C)，即实际室温约为 22.4°C - 22.7°C，这在夏季夜晚是正常的。因此，主要风险并非温度过高导致的即时火灾，而是**行为异常**：用户在深夜（23:25）开启了灶具，但此时全屋（含厨房）均无人员活动记录。这属于典型的‘无人看管烹饪’场景，极易导致忘记关火引发事故。"

## 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",

}
```

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。

    "推理步骤 2: 在此空置状态下，于 18:05:00 至 18:07:00 之间，入户门锁（front_door_lock）连续三次报告 'LockOperationError(source=Keypad)'。这种在短时间内针对同一输入源（键盘/密码盘）的重复失败尝试是典型的暴力破解或试错行为特征。",
    "推理步骤 3: 虽然不能排除是家庭成员忘记密码导致的误操作，但考虑到此时家中无人，且错误发生在特定时间段，结合安全最佳实践，必须将其视为潜在的安全威胁（外部人员尝试进入或内部人员因遗忘密码而反复尝试），属于 lock_malfunction 或潜在的 intrusion 前兆。"

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
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：

```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",

    "关键证据2"
  ],
  "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。

    "推理步骤 3: 关联分析与风险评估。虽然温度数据看似正常（数值约为 23xx，符合摄氏度 x10 的常见 Matter 编码格式，且趋势平稳），但门锁的连续报错是明确的安全威胁信号。结合‘无人’和‘连续多次失败’两个特征，极大概率是外部入侵者正在尝试进入，或者门锁本身存在严重故障导致无法锁定/解锁，这两种情况都构成高风险。"

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
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。

Chosen response:

  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "检测到儿童房在无人状态下出现异常高温，随后有人员进入并开启阳台灯，存在儿童独自留在室内或环境失控的风险。",
  "reasoning": [
    "推理步骤 1: 分析温度数据发现，从 14:30 到 15:20，儿童房 (kids_room) 温度传感器读数持续下降（从 24.66°C 降至 24.20°C），而客厅、主卧等其他房间温度也同步下降，这表明空调可能正在运行或室外气温较低，整体环境温度处于正常调节范围。",
    "推理步骤 2: 关键异常点出现在 16:10，此时儿童房运动传感器突然报告 Occupancy = 1（有人），但紧接着在 16:30 和 17:30 多次报告 Occupancy = 0（无人）。更严重的是，在 16:14 分，阳台门接触传感器状态变为 False（打开），且 16:15 分阳台灯被点亮。",
    "推理步骤 3: 结合时间线推断：16:10 有人进入儿童房，随后该人离开（16:30 显示无人），但在离开前并未关闭阳台门（16:14 开门）也未关闭阳台灯（16:15 开灯）。考虑到这是重点关注的儿童房，这种‘进屋 - 开门 - 开灯 - 离开’的模式，若发生在非家长时段或家长不在场时，极有可能是儿童独自活动后误操作，或者有人非法进入后迅速撤离，留下了安全隐患（如窗户/门未关好导致儿童滞留风险或入侵者尾随）。特别是考虑到儿童房通常由家长监管，这种异常的进出和门窗状态变化触发了儿童安全警报。",
    "关键证据": [
      "2026-07-11T16:10:00 儿童房运动传感器检测到有人 (Occupancy=1)。",
      "2026-07-11T16:14:00 阳台门接触传感器状态变为 False (打开)，且 16:15:00 阳台灯被点亮。",
      "2026-07-11T16:30:00 及之后儿童房再次显示无人 (Occupancy=0)，但阳台门仍处于开启状态且灯光亮起，表明离开时未恢复安全状态。"
    ],
    "recommended_actions": [
      "立即检查儿童房及阳台区域，确认是否有儿童被困或遗留物品，确保门窗已正确关闭。",
      "联系住户核实 16:10-16:30 期间的人员活动情况，确认是否为儿童独自活动或外部入侵。",
      "建议检查儿童房智能门锁和阳台门的联动设置，确保当检测到儿童房有人且阳台门打开时能自动报警或通知监护人。"

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
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。

Rejected response:

  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在连续多次按键尝试失败后，最终成功解锁并开门，且伴随室内灯光和空调自动开启，疑似遭遇暴力破解或密码试错攻击。",
  "reasoning": [
    "推理步骤 1: 在 18:05:00 至 18:07:00 期间，front_door_lock 记录了两次 'LockOperationError(source=Keypad)' 事件，表明用户（或入侵者）正在尝试使用键盘输入密码但连续失败。",
    "推理步骤 2: 紧接着在 18:07:00，系统报告了一次成功的 'LockOperation(LockOperationType=1)'（通常代表 Unlock），随后 DoorLock.LockState 变为 2（Unlocked），证明门锁被打开。",
    "推理步骤 3: 最关键的异常在于时间戳的紧密性：门锁状态改变（18:07:00）仅 2 秒后（18:07:02），前门接触传感器 (front_door_contact) 立即变为 False（门已开）。更可疑的是，几乎同时（18:07:03-18:07:08），客厅的 occupancy、light 和 air_conditioner 全部自动激活。这种‘试错 - 解锁 - 进门 - 全屋联动’的极速序列不符合正常住户回家后的行为模式（通常会有开门动作间隔，且不会瞬间触发所有设备），强烈暗示有人通过快速试错密码进入家中，或者门锁存在严重的逻辑漏洞/被劫持。",
    "关键证据": [
      "18:05:00 和 18:06:00 出现连续的 Keypad 操作错误。",
      "18:07:00 门锁状态迅速从锁定变为解锁 (LockState=2)。",
      "18:07:02 门接触传感器立即检测到门打开 (False)，且随后全屋灯光和空调瞬间启动，缺乏正常的过渡延迟。"
    ],
    "recommended_actions": [
      "立即强制重置入户门锁密码，并检查是否支持远程固件更新以修复潜在的键盘暴力破解漏洞。",
      "通知住户确认是否有人非法闯入，若未授权进入请立即报警。",
      "审查智能家居系统的自动化规则，确保门锁解锁不应无条件直接触发全屋高能耗设备（如空调）的全功率运行，以防被利用作为入侵信号。"

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。

    "推理步骤 3: 结合上下文，从 16:10 到 16:14 期间，所有主要房间（包括客厅、主卧、次卧）的运动传感器均报告为 0（无人）。这意味着进入阳台的人员并非家庭成员正常回家后的路径，而是可能通过其他方式（如窗户或后门）潜入，或者是在家中其他成员不知情的情况下进行的非授权访问。考虑到重点监控的是儿童房安全，这种非正常的夜间/傍晚时段阳台开启及随后的短暂室内活动高度可疑。",

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。
