What changed after the control plane

ADR-008 gave the gateway an HTTP control plane. signal_watcher still drafted from Invest AI Top-1 alone while InvestSim evidence stayed "documented for later."

ADR-010 — consume execution evidence

When INVESTSIM_BASE_URL is set (or evidence required), run_once() fetches GET /api/execution/evidence/latest before drafting and blocks unless the mode passes:

• require_eligible (default)
• require_present
• off

Drafts carry invest_sim_evidence + source_ref. place_equity_order path unchanged (still G1–G7).

ADR-011 — prefer lab strategy

Strategy slug resolution:

1. Ops override INVESTSIM_EVIDENCE_STRATEGY
2. Lab GET /api/mcp-preferred when prefer-lab is on (default)
3. Fallback ai-top-1

Symbol/side still from Invest AI Top-1 Buy. InvestSim never called for place_*. Eligible evidence still does not auto-approve.

Takeaway

Wire the lab into the draft gate. Keep the human on the place gate.
