fetch-investments

Use when the user says "fetch investments", "fetch ibkr", "fetch interactive brokers", "pull portfolio", "fetch brokerage", "snapshot ibkr", or any portfolio-snapshot equivalent — and as the best-effort IBKR step inside daily-run. The connector authenticates only in interactive sessions, so unattended runs typically skip it with a warning. Ingests the IBKR connector's trade history into the trades ledger on a user-mapped account (so it stops needing trade screenshots), plus a positions snapshot used for reconciliation + new-user bootstrap. Skips gracefully — best-effort, like a failed bank source — when the connector isn't connected.
