Annotations: Add source (from 02d) is a small MUI Dialog for data vendors only. ① Vendor: MarketData.app (Equity, Option), Polygon (Crypto, Equity, Option); vendors already added show as disabled (variant: open, adding a second vendor). ② API key, password field with show / hide; stored encrypted, shown later as •••• and the last 4 characters. ③ Test connection sends one read-only quote request; result inline (✓ Success / ✕ error). ④ Add saves the vendor; it then appears in Sources and in the Add data source list (02b). No name or notes: there is one source per vendor.
