research-hub Multi-AI Router

This is a planning router. It writes a coordination plan and per-leaf briefs; the supported leaves execute. The current leaf set is:

• codex-delegate: implementation-heavy or repetitive work with a structured result.json contract.
• antigravity-delegate: narrowly scoped, non-honesty-critical mechanical work with an agy_result_*.md contract.

The archived Gemini delegate is not a supported leaf. Long-context reading, CJK drafting, scientific judgment, governance, and final review stay with the primary model unless the operator has separately verified another adapter.

When to invoke

Invoke only when a single round needs two or more delegates and at least one task operates on research-hub artifacts. Examples:
