2925 OpenAI code polling: list-only false negative and detail-opening fix (2026-05-11)

Trigger

During the 2925 + OpenAI signup test, automated polling reported no current-alias code after strict 3 mailbox refresh rounds -> 1 OpenAI resend cycles. BOSS later manually checked the same 2925 mailbox (chickliu2030@2925.com) and found that the OpenAI verification code had actually arrived.

Lesson

A 2925 Webmail list-page text scan can be a false negative. Do not conclude non-delivery only because the list page lacks the generated alias/local-part or a visible 6-digit code.

Likely causes:

• The list page may not render the full recipient/alias or message body.
• The visible list may only show the base mailbox (chickliu2030@2925.com) or a compact row.
• Codes/alias evidence may exist only after opening the message detail pane/page.
• OpenAI mail may arrive after repeated resends even when earlier list scans show hasLocal=false.

Correct polling pattern

For 2925 OpenAI verification mail:

1. Verify the top/displayed mailbox account equals the selected pool account.
2. Explicitly click the visible 刷新 button in both Inbox and Junk.
3. Search for candidate rows by sender/subject keywords: OpenAI, ChatGPT, 验证码, verification, code, and also current local-part if visible.
4. Open candidate rows/messages before deciding no code exists.
5. In the detail view, extract a strict 6-digit code only when the detail text or headers match the current alias/local-part, or the message is unambiguously from the current OpenAI send window.
6. If no candidate appears, continue the BOSS cadence: 3 refresh rounds then one OpenAI resend.
7. If BOSS/manual UI finds a code after automation says none, treat it as a polling bug, not a provider-delivery failure.

Operational correction

The earlier DONE_NO_CURRENT_ALIAS_AFTER_10_RESENDS result should be interpreted narrowly:

Automation did not detect the code via list-page scanning.
It does NOT prove the 2925 alias cannot receive OpenAI mail.

Future runners should log whether they opened a message detail (opened=true) and should save a redacted detail snippet for debugging when candidate messages exist but no code is extracted.
