The federal dollar formalized a Spanish-dollar unit already used for public debt, requisitions and value reckoning, rather than borrowing only a coin weight. The regional account-unit association is qualified; provincial pound conversions remain unresolved.
Corrected interpretation: Revision 28 supplies a new evidence basis for R0035. Combined contemporary account usage and enacted federal denomination remove the earlier coin-standard-only concern. Provincial pounds are additional local inputs requiring individual conversion histories, not a reason to qualify this specific Spanish-dollar branch. Replacement evidence: C1795.

Oliva Manso dates Pedro I’s silver real approximately to 1363 and identifies the French gros tournois of 1361 as a model, while emphasizing differences in metrology. The 1373 ordinance valued the real at three maravedís. Coin design and valuation establish neither adoption of the French account unit nor a founding date for separate real accounting.

Inference C2112
The Spanish silver real and peso account tradition is treated as a qualified branch within Castilian maravedí reckoning. The 1497 reform rated the real at 34 maravedís while maravedí accounts continued; scholarship describes real accounting within that common sixteenth-century system and subsequent divergence between silver and vellón values from 1603. This is an inference of local account differentiation from the combined evidence, not a claim that a coin tariff alone creates ancestry or that the real replaced and abolished the maravedí in 1497. The interval is a development window, not a known founding reform.
