Field notes
The page treats reliability as a set of testable rules rather than a general promise: local SQLite records sales first, synchronization can be retried, and stock changes merge through UUID-keyed append-only rows. It also documents an encrypted-backup workflow and a destructive restore drill, alongside research repositories covering 28 FX pairs. Interactive controls expose parts of the sync and learning experiments directly on the portfolio homepage.
