Problem

With the ticket subsystem gone (#229), admins need a quick, manual way to see whether an OpenAI OAuth account currently answers like a degraded model. Our own records show the candy question separates the two reliably: correct answers are 21, while degraded answers are typically 29.

Change

Account test dialog, OpenAI OAuth accounts only (owner-approved preview, 2026-10-03):

• New test mode. 「测试模式」 gets a third option, 「质量判分（糖果题）」. Selecting it switches reasoning effort to high when the model offers it; it can be changed, and leaving the mode restores the previous choice.
• Fixed question. It replaces the custom prompt and is shown read-only, collapsed by default. It is sent unchanged over the ordinary account-test path (SHA-256 05cc85bb…f5a7a7, asserted by a unit test).
• Verdict card. Shown after the run:
  • 初判: 未见异常 (final number 21), 疑似降智 (another number), or 无法判定 (no number, an incomplete stream or a failed test);
  • the final number and the reasoning tokens, with a hint when the count is exactly 516 (every such answer in our records was wrong);
  • the model the upstream declared, compared with the requested upstream model;
  • a note that the verdict is a hint only.
• Nothing is stored and scheduling is untouched. A successful run is still a successful connection test, same as before.

The final-number parser prefers explicit answer markers (\boxed{}, 答案/至少需要…/at least …). It skips markers inside hypothetical clauses (「若完全随机摸取，则答案会是 29 个」), ignores counts of shapes, flavours and dates, and resolves arithmetic chains. Over the 134 recorded answers in our evidence it never reports 21 for a wrong answer.

Backend: the account-test stream now reports reasoning_tokens on test_complete for OpenAI Responses tests. The field is optional and omitted otherwise, so other platforms are unchanged.

Dialog-wide: a test stream that ends without a terminal event now shows 「连接在测试完成前结束」 instead of staying on "connecting" (owner decision).

Verification

• accountQualityCheck.spec.ts: 52 cases (hash, Chinese and English answers, verdict states);
• AccountTestModal.qualityCheck.spec.ts, plus the existing AccountTestModal specs;
• check:i18n, vue-tsc --noEmit, eslint on the changed files;
• go build ./..., and TestAccountConnectionStreamReportsOpenAIReasoningTokens / TestAccountConnectionStreamContract (-tags unit);
• a local mock-data preview of every state, with no console errors.

Not run: real model calls.
