- Validate voice.provider against known whitelist (xiaomi|stepfun) in beat-audio route to return a clear 400 instead of falling through - Move single-char pronouns (他/她) to weak-signal fallback in detectGender to avoid false positives on compounds like 其他 - Update .env.example with StepFun configuration examples Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
