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: ...",

    "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。

    " occupancy 逻辑验证：当厨房灶具开启时，虽然重点关注的 kids_room_occupancy 传感器未直接报告变化（可能因距离较远或被遮挡），但后续日志显示 living_room、entrance、master_bedroom 等多处传感器同时变为 Occupancy=1，表明家庭成员正在家中正常活动，而非入侵者单独行动。",
    "设备状态一致性：入户门锁在 22:50 正常上锁，窗户关闭，温度传感器读数稳定且在各房间间差异合理（约 22.4°C - 22.6°C），烟雾报警器和漏水传感器未触发警报，所有设备行为符合 Matter 协议下的正常交互逻辑。"
  ],
  "key_evidence": [
    "多房间 occupancy 传感器在晚间时段同步显示有人 (Occupancy=1)，证实为家庭成员活动。",
    "厨房灶具 (cook_surface) 仅在有人活动的时段开启，且持续时间短，无长时间无人看管迹象。",
    "入户门传感器 (front_door_contact) 在上锁后保持闭合状态，无非法闯入信号。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持当前的设备监控策略，定期校准运动传感器以减少误报。"

## 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: ...",

    "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。

    "步骤 1: 时间线分析显示，在 16:05:00 入户门锁被手动上锁 (LockState=2)，紧接着在 16:05:02 入户门传感器报告门已关闭 (False)。这表明住户正常离家并锁好了前门。",
    "步骤 2: 然而，在 16:14:00，位于另一侧的阳台门传感器 (balcony_door_contact) 状态变为 False (打开)。考虑到此时入户门已锁且无其他开门记录，阳台门异常开启极可能是非法闯入或有人通过未锁的阳台门进入室内。",
    "步骤 3: 紧随阳台门开启之后 (16:14:08)，儿童房运动传感器检测到人员存在，并在 16:14:00 左右儿童房灯光 (kids_room_light) 被开启。这种‘先开门、后开灯’且发生在非正常活动时间段（下午 4 点多，通常孩子应在学校或家中休息）的模式，强烈暗示有陌生人进入了儿童房区域。",
    "步骤 4: 结合跨天摘要中 kids_room 的高频活动计数 (234)，以及本次事件中儿童房持续有人 (Occupancy=1) 直到日志结束，进一步证实了该房间内发生了非预期的长时间占用，符合入侵者探索或滞留的特征。"

    "16:14:00 阳台门传感器突然变为打开状态 (StateValue=False)，且无对应的开门操作日志。",
    "16:14:08 儿童房灯光开启及运动传感器随即报有人，时间上与阳台门开启高度相关。",
    "儿童房在事件发生后持续保持有人状态 (Occupancy=1)，直至日志末尾。"
  ],
  "recommended_actions": [
    "立即通知住户返回家中，检查儿童房及全屋情况，确认是否有陌生人闯入。",
    "联系当地警方报案，提供具体的入侵时间窗口 (16:14:00 - 16:15:00) 和涉及设备 ID。",
    "检查阳台门锁具是否损坏或被破坏，并暂时将阳台门设为常闭/锁定模式，直到进一步调查。",

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。

Rejected response:

{

  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且门窗关闭的情况下，阳台门被打开并伴随灯光开启，随后出现多人在户内活动的迹象。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-27T16:14:00 时，儿童房 (kids_room) 的运动传感器报告有人 (Occupancy=1)，但随后的温度读数波动较大且未持续上升，结合上下文推断此时可能为短暂停留或设备误报，但关键在于紧接着的状态变化。更关键的异常发生在 16:14:00 之后。",
    "推理步骤 2: 在 2026-08-27T16:14:00，阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开）。此时日志中并未显示入户门 (entrance) 或儿童房窗户被打开的记录，且之前儿童房处于占用状态，若为正常家庭成员活动，通常会有明确的开门路径逻辑。",
    "推理步骤 3: 最可疑的证据是紧随其后的行为模式：在阳台门打开后仅 1 分钟 (16:15:00)，阳台灯 (balcony_light) 被打开。更重要的是，从 15:20 到 16:15 期间，系统记录了多个房间（客厅、主卧、餐厅、厨房）的 occupancy 为 1，但在 16:14 阳台门打开这一关键节点，缺乏对应的“进入”动作记录（如玄关运动传感器先于阳台门动作），且儿童房在 16:14 仍有 occupancy 信号却无后续离开记录，暗示可能存在非授权人员通过阳台进入并在室内移动，或者发生了尾随/非法闯入事件导致室内人员分布异常。考虑到这是安全分析任务，这种‘静默开门 + 开灯 + 多点同时有人’的模式高度符合入侵特征。",
    "修正推理步骤 3 (基于更严谨的逻辑): 重新审视数据，16:14 阳台门打开，16:15 阳台灯亮起。虽然不能直接证明是坏人，但在家庭安防场景下，非工作时间段（下午 4 点多，虽非深夜但需警惕）阳台门突然打开且没有关联的入户门操作记录，属于高风险事件。特别是如果住户习惯是关着阳台门的，此行为即为异常。此外，儿童房在 16:14 仍显示有人，而阳台门开了，这可能意味着有人从阳台进入并进入了儿童房区域，或者入侵者正在屋内活动。综合来看，这构成了潜在的入侵威胁。"
  ],
  "key_evidence": [
    "2026-08-27T16:14:00 阳台门接触传感器状态变为 False (门被打开)。",
    "2026-08-27T16:15:00 阳台灯自动或手动开启 (OnOff.OnOff = True)。",
    "在阳台门打开前后，多个房间（包括儿童房）同时报告有人存在，但未观察到正常的入户开门序列。"
  ],
  "recommended_actions": [
    "立即通知住户确认家中是否有人及阳台门开启原因。",

## 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: ..."
  ],

    "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": "儿童反复尝试打开受限区域",
  "reasoning": [

Rejected response:

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在连续三次按键操作后均报告错误，且随后门状态异常开启，存在极高的非法入侵或内部人员误操作导致的安全风险。",

    "推理步骤 2: 在最后一次报错后的极短时间内（18:04:06 客厅有人，18:06 锁报错），虽然未见明确的开门成功日志，但结合前文 17:44 分曾发生过一次成功的解锁并伴随门接触传感器状态变为 False (False 通常代表门未闭合/打开) 的模式，连续的认证失败往往意味着暴力破解尝试、忘记密码导致的反复试错，或者更危险的情况——有人在门外试图通过技术手段干扰锁具。",
    "推理步骤 3: 考虑到这是儿童房（kids_room）和主卧室所在的住宅环境，入户门锁是最后一道防线。连续的错误日志不仅仅是用户操作失误，更可能预示着外部入侵尝试（Brute-force attack on keypad）或设备本身的严重故障（如电池耗尽导致无法响应正确指令）。若此时门锁处于未锁定状态（参考 17:44 的状态变化逻辑），家庭将完全暴露于风险之中。",

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。

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且温度异常的情况下，阳台门被打开并开启灯光，随后入户门锁被手动上锁。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-04T14:30 至 16:14 期间，儿童房 (kids_room) 的温度传感器持续报告数值（约 2400-2450），这明显是摄氏度的十分之一单位（即 24.0°C - 24.5°C），表明室内有人活动或环境稳定。然而，关键转折点出现在 16:14，此时儿童房运动传感器仍显示有人 (Occupancy=1)，但紧接着在 16:14:00 阳台门接触传感器状态变为 False (False 通常代表门未关闭/打开)。",
    "推理步骤 2: 更关键的异常在于逻辑顺序。通常在家庭场景中，如果有人在屋内，开门会触发警报或导致人员移动。但在 16:14:00 阳台门打开后，系统并未立即记录到儿童房内的人员离开（直到 16:14:00 之后不久才再次确认 occupancy=1，但这可能是误报或延迟）。更重要的是，在 16:25:00，入户门锁被手动上锁 (LockOperationType=1, LockState=2)。",
    "推理步骤 3: 结合上下文，从 15:30 开始，客厅、次卧等区域 occupancy 变为 0，而主卧和餐厅偶尔有活动，暗示主要家庭成员可能已外出或处于休息状态。此时，阳台门被打开，紧接着入户门被上锁。这种‘先开外门，再锁内门’的行为模式，极有可能是外部人员试图进入家中，或者内部人员试图将某人困在屋内（考虑到儿童房一直有人，存在儿童安全或绑架风险）。特别是如果这是非家庭成员操作，则构成严重的入侵威胁。",
    "推理步骤 4: 虽然日志中显示 16:14 时儿童房 occupancy 为 1，但如果入侵者是从阳台进入，他们可能会先打开阳台门，然后潜入室内。入户门的锁定动作发生在 16:25，距离阳台门打开仅 11 分钟，且在此期间没有其他明显的家庭成员活动记录（如玄关灯频繁开关或大量人员进出），这使得该行为显得非常可疑。"

    "事件发生时间段内，其他房间（除主卧和餐厅偶发外）多显示无人状态，增加了单人异常操作的可能性。"
