Skip OpenAI messages-dispatch gpt-5.x defaults for OpenCode groups and composite OpenCode targets. Filter unpriced claude-* billing candidates, estimate count_tokens locally, sanitize body session IDs before setting X-OpenCode-Session, and treat Zen 402 as recoverable payg cooldown. Stop rewriting the inbound body before protocol routing so account model_mapping applies once and usage_logs.model stays the client name.
