What it does

Workflow engine — JSON-defined step sequences — text, number, date, select, photo, barcode, QR, GPS, audio.
Offline-first capture — Sessions are stored locally in SQLite. Delivery queues automatically when back online.
Configurable providers — Each provider is a submission target, a workflow source, or both. One unified model.
Background delivery — WorkManager with exponential backoff. Multipart or JSON. Per-attempt delivery log.
Subscribe to catalogs — Connect to any FCC server and sync its workflow catalog in the background.
Secure sync — Bearer token auth. Per-org isolation. No data leaves the device without a configured target.
