消息 ID 符合官方格式且每次唯一

{
  "ids": [
    "msg_011CeX1PsXT3bf48QB16x312",
    "msg_011CeX1Q8KC27SSotuoX5iuD"

}

原样回传通过、篡改签名被上游拒绝：加密级验证通过，上游为 Anthropic 官方

SSE 事件序列完整，符合官方规范

Tool Use 正常，参数与 stop_reason 均符合规范

{
  "stop_reason": "tool_use",
  "blockTypes": [
    "tool_use"
  ],
  "toolId": "toolu_01XY6tvq9WqWNzMbzd3nbh9B",
  "input": {
    "city": "Tokyo"
  }
}

该模型不支持 assistant 预填充（Claude 5 代已移除此特性），跳过

stop_sequence 命中并正确回填

{
  "stop_reason": "stop_sequence",
  "stop_sequence": "FIVE",
  "text": "ONE TWO THREE FOUR "
}

用量稳定 (16 tokens)，无注入痕迹

{
  "input_tokens": [
    16,
    16
  ],
  "output_tokens": [
    8,
    4
  ],
  "expectedInputApprox": "10-16"
}

模型确认无隐藏指令

{
  "reply": "NONE"
}

身份为 Anthropic，temperature=0 输出稳定

{
  "who": "Anthropic",
  "math": [
    "391",
    "391"
  ],
  "models": [
    "claude-fable-5",
    "claude-fable-5",

}

PDF 内容识别正确

{

  "secret": "KIWI-2404",
  "reply": "KIWI-2404"
}

缓存写入了但第二次未命中：中转站可能在多上游间轮询，缓存无法复用

{
  "first": {
    "input": 61,
    "creation": 5071,
    "read": 0
  },
  "second": {
    "input": 61,
    "creation": 5071,
    "read": 0
  }
}

上游安全分类器拒答了长文本探针（{"type":"refusal","category":"cyber","explanation":"This request triggered restrictions on violative cyber content and was blocked under Anthropic's Usage Policy. To learn more, see https://platform.claude.com/docs/en/build-with-claude/refusals-and-fallback. API integrators: you can reduce refusals for your users by configuring a fallback model — see https://platform.claude.com/docs/en/build-with-claude/refusals-and-fallback"}）：这是 Anthropic 官方的流式拒答格式，属于官方侧误判而非中转站问题；本次无法评估长上下文
