# Doctrine #322 — Wave349 zero-défaut WEVIA-FIRST

## Principe

WEVIA Master FIRST en NL chat USER. Yacine fait RIEN, WEVIA Master fait TOUT. Multi-agent + multi-server + multi-IA + multi-cookie en parallèle.

## Pattern

```
USER NL chat → wevia-chat-v2-direct.php → 
  intent classifier → handler → mass dispatch →
    20 pools parallel → eco tracking D384 → 
      first_success / top_k / consensus / merge
```
