Switching to LIVE trades real money. Requirements enforced server-side: fresh re-auth, the typed phrase GO LIVE REAL MONEY, an explicit deployable-capital cap, and no open paper positions (or explicit flatten). The engine completes the switch and flips the badge — not this page. Note: the live broker adapter is not installed yet; the engine will reject the command until the execution layer ships. The full safety chain is still exercised end-to-end.
