The split that keeps people honest

Invest AI ranks and caches. InvestSim papers many sleeves. Robinhood MCP drafts orders under gates.

If any one of those owns everything, you get either a fake broker or three Yahoo series that disagree next month.

The contract

Worker bars/signals/paper/lab  →  InvestSim evidence + preferred
                               →  MCP fail-closed draft
                               →  Human G1 confirm
                               →  place_* still gated

Eligible evidence means "allowed to draft with citation." It does not mean "autotrade."

Why this shipped as ADRs, not vibes

• Invest AI ADR-035–039: events → bars → paper → strategy-lab → EEE
• InvestSim ADR 0024/0031: mcp-preferred + Tier-2.5 sleeves
• Robinhood MCP ADR-010/011: consume evidence + prefer lab strategy

Takeaway

Share bars. Separate ownership. Never confuse lab green lights with broker authority.
