+- Accounts batch-import confirm dialog is wider (`md` / ~32rem) with slightly roomier padding so the provider card, region toggle, and actions are less cramped.
+- CodeArts (码道) console credential import works again: the adapter exposes its importer where the console looks for it, so pasting a `codearts-oauth-v1` credential no longer answers `unsupported_format`.
+- CodeArts chat now sends WorkBuddy tip `28527f4` / hub #723 session headers after signing: account-stable `x-ot-session-id` and `user-session-id`, plus a fresh `x-ot-trace-id` per request (kept out of SignedHeaders), so Huawei no longer treats every call as a new concurrent session.
+- Codex model catalog adds `gpt-6.1-terra` (GPT-6.1 Terra) from the upstream client / CLIProxyAPI list, with the same slim fields as sibling `gpt-6.1-sol`.
+- Request-log retention no longer leaves orphan rows in `request_attempts`, `request_usage_details`, and `request_stream_diagnostics`: the purge deletes child rows in the same transaction instead of relying on `ON DELETE CASCADE`, which was inert on any connection opened without `PRAGMA foreign_keys`.
+- `PRAGMA foreign_keys` now travels in the SQLite DSN, so every connection the pool opens enforces the declared cascades instead of only the one that ran the startup `Exec`.
+- The Usage **Cost** tab window follows `CLI2API_LOG_RETENTION_DAYS` instead of a hard-coded 7 days, so raising retention makes the older cost history readable.

+- 账号批量导入确认弹窗加宽（`md` / 约 32rem），内边距略增，提供商卡片、区域切换与操作按钮不再显得挤。
+- 码道（CodeArts）控制台「导入凭证」恢复正常：适配器按控制台查找的位置暴露导入器，粘贴 `codearts-oauth-v1` 凭证不再返回 `unsupported_format`。
+- 码道（CodeArts）聊天在签名之后补发 WorkBuddy tip `28527f4` / hub #723 会话头：账号级稳定的 `x-ot-session-id` 与 `user-session-id`，以及每请求新的 `x-ot-trace-id`（不进入 SignedHeaders），避免华为云把每次请求都当成新建并发会话。
+- Codex 模型目录新增上游客户端 / CLIProxyAPI 列表中的 `gpt-6.1-terra`（GPT-6.1 Terra），字段结构与同代 `gpt-6.1-sol` 一致。
+- 请求日志清理不再在 `request_attempts`、`request_usage_details`、`request_stream_diagnostics` 里留下孤儿行：清理改为在同一事务里显式删除子表行，不再依赖 `ON DELETE CASCADE`——该级联在任何未设置 `PRAGMA foreign_keys` 的连接上都不生效。
+- `PRAGMA foreign_keys` 改为写进 SQLite DSN，连接池新开的每条连接都遵守已声明的级联，而不只是启动时执行过 `Exec` 的那一条。
+- 用量页「费用」选项卡的时间范围跟随 `CLI2API_LOG_RETENTION_DAYS`，不再写死 7 天；调大保留期后能看到更早的费用历史。
