- History retention 1d → 30d（60s × 30d ≈ 43200 行/model，PG 无压力）；
  ComputeAvailability* 不再 UNION rollup 表，直接扫 histories 精度更高。
- Timeline bar 四级高度+颜色双重编码：operational 高+绿 / degraded 中+黄 /
  failed+error 短+红 / 未测试 很短+灰。
- migration 113 seed「Claude Code 伪装」模板（ON CONFLICT DO NOTHING）。
  user_id 用 legacy 格式（user_<64hex>_account_<uuid>_session_<uuid>），
  避免新版 JSON 字符串内嵌 JSON 在编辑器里一长串 \" 难读。
- MonitorAdvancedRequestConfig 加「格式化」按钮 + white-space:pre
  让 body textarea 对长字符串不压扁。
