ECB daily euro foreign exchange reference quotes
Preparatory source meanings for native time, currency and rate strings from the ECB daily XML resource. Reference date has no publication instant; the indicative rate expresses quote-currency units per one EUR with lexical digits preserved. No stable cross-read identity, synthetic EUR row, reciprocal, historical lookup or accepted country/tender/transaction join is asserted. CC0 covers authored metadata only; ECB rate reuse terms remain separate. Source execution and paid applicability stay blocked.
