A wrapper statement can support that same canonical event, so calculations count it once without deleting either observation. You also write positions/cash observations for reconciliation and history anchors. There is no staged file; live rows have `source_doc_id=NULL` but explicit feed provenance. You never touch Drive. **This supplements existing evidence; it does not replace or delete it.** Historical screenshots and wrapper statements stay attached to the same canonical events. The connector makes future screenshots unnecessary but never assumes that a same-date/same-amount row is automatically a duplicate. **Logical accounts are not feeds.** Each provider account gets an `account_feeds(provider='ibkr')` row attached to the logical account it describes. A wrapper broker and IBKR are usually two feeds for one account; creating a second account would double-count the portfolio. Distinct IBKR accounts may map separately when they are genuinely separate economic accounts. **Interactive auth, best-effort everywhere.** The IBKR connector is Anthropic's certified Interactive Brokers connector, added by the u
