Sovereign ingestion

Name: @pocket-portfolio/importer
Author: Open Portfolio

Broker statements are parsed on the device — not warehoused on ours. The MIT-licensed importer ships 19+ deterministic adapters plus Smart Mapping for everything else, with zero raw-row egress through your perimeter.

Two surfaces, one substrate

We do not blur B2B infrastructure with the consumer terminal. Procurement reads here; operators stress-test on Pocket.

SDK packages, design partnership, Tier 1 programmes, and procurement narrative for regulated builders.

Pocket Portfolio — adversarial test harness

Thousands of real CSVs, messy headers, and everyday edge cases run through the same parsers in production — before your audit.

Verified broker adapters

Each adapter is tested against real export fixtures. Unknown brokers fall through to column-level Smart Mapping — still client-side, still out of your data lake.

OpenBrokerCSV — the interchange format

OpenBrokerCSV is the normalized ledger we emit after adapter detection. Third parties can target one schema instead of re-implementing every broker dialect.
