On 19 November 2023 Javier Milei defeated Sergio Massa in Argentina’s presidential runoff.
Context
Villarruel was the running mate. Neighbouring 10 December oath is the child.
10 December 2023 oath is the child. Devaluation 13 December is a later shock.
The President of Argentina heads the federal executive, issues decrees of necessity and urgency subject to congressional review, and appoints the cabinet. He does not write INDEC prints, an IMF board decision, a US Treasury backstop, or a Central Bank balance sheet by himself. Congress, governors, the BCRA, and coalition deputies share specific files. Dollarisation announced is not dollarisation completed.
Why it matters
The path is democratic resilience: a completed certified rotation after a polarised runoff is a dated peaceful-contest instrument.

What the sources establish
Ministry of the Interior of Argentina carries the official instrument or communique. Reuters records the same dated act independently.
Established: 19 November 2023 runoff victory, independently reported and certified.
Not established: that dollarisation was thereby enacted, or a unique later inflation coefficient from that Sunday.
The electoral authority certified. Massa lost. He won.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Milei wins the 2023 presidential runoff, not a later speech about Milei wins the 2023 presidential runoff.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Voters chose. The electoral authority certified. Massa lost. He won. That limit is the alternative to treating office-holding as authorship of every later series.
