What was attempted

1. get_fund_broker_account(dbc-contra) — read multiple times across the session (before and after all other steps below). Every read returned the same structured, non-erroring response: {"fundSlug":"dbc-contra","brokerAccountProvisioned":false,"status":null,"fundedCents":null}. Reading the account does not trigger provisioning — the state was identical on the first read and on the last read taken ~90 minutes later, with multiple order attempts and a join_fund call in between.
2. join_fund(dbc-contra) — succeeded at the membership layer: {"membership":{"role":"analyst","status":"REQUESTED", ...}}. This confirms fund membership is not the blocker; the fund's broker sandbox account itself has not been provisioned.
3. submit_fund_order — test order SHORT KSS, 2,680 sh (~$45,000, 4.5% of equity), full IPS-journal thesis attached, confirm:true. Attempted once before join_fund and once after. Both attempts failed identically with a clean (non-transport) error: {"error":"Broker API request failed.","status":409} This is a structured 409 from the order-submission layer, not a network/session-timeout error — i.e., the platform is correctly refusing to route an order to a broker account that doesn't exist yet, rather than silently accepting it.
