基于 Claude Code 2.1.88 反编译源码，完成全面的反追踪指纹还原： 1. 版本升级 2.1.87 → 2.1.88（constants.go, identity_service.go, proxy.js） 2. 新增 6 个 beta header 常量（task-budgets, token-efficient-tools, structured-outputs, advisor, web-search） 3. 更新所有组合 beta header 字符串，加入 context-1m, redact-thinking, effort 等 4. 注入 x-anthropic-billing-header attribution block 到 system prompt 首位 - 完整复刻 fingerprint 算法: SHA256(salt + msg[4,7,20] + version)[:3] - 正确省略 cch 字段（npm 版行为，非原生二进制） 5. X-Claude-Code-Session-Id: 有则同步，无则按 account 生成 6. x-client-request-id: 每请求自动生成 UUID 7. Bootstrap 预热: 模拟 GET /api/claude_cli/bootstrap（per-account, 1h cooldown） 8. 停止无条件剥离 temperature/tool_choice（与真实 CLI 行为一致） Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
