What's Changed
🛡️ 403 Account Rotation
When an account receives a 403 VALIDATION_REQUIRED / ACCOUNT_DISABLED / USER_DISABLED error, the proxy now automatically rotates to the next healthy account instead of only cycling endpoints.
- Detects Google account verification requirements (
VALIDATION_REQUIRED,ACCOUNT_DISABLED,USER_DISABLED) - Marks affected account as invalid with verification URL (if provided)
- Rotates to next available account seamlessly
- WebUI shows FIX button linking directly to Google's verification page
clearInvalid()re-enables accounts after verification is completed- Returns immediate error when all accounts are invalid (no infinite wait)
Originally implemented by @liuxiaopai-ai in #255. Their contribution was squash-merged via #280 — full credit to them for the original implementation.
⏱️ Request Throttling (Opt-in)
Adds opt-in request throttling to prevent rate limit exhaustion under heavy concurrent usage.
