MARIANO R. ALONSO / CENTRAL — Mayor

526 current mayor/council offices. Named-geography mapping repairs changing historical district codes; original labels retained. Distinct source list numbers fix three acronym-collision vote discrepancies. Numeric totals reconcile, but boundary changes, intervening events and current control are not certified country-wide; the blanket CI clearance is removed.

Historical competition

Competitiveness index for a verified actual-event sequence withheld. Actual-event and/or comparability review incomplete.

Provisional imported-series CI: 72.2/100. This uses the three displayed comparison cycles and retains the open event/boundary audit. It does not confirm the latest three actual completed elections.

Grouped party-share volatility: latest interval 11.1 points; earlier interval 11.7 points; two-interval mean 11.4 points.

Grouped Pedersen lower bound (percentage points). Standalone ANR, PLRA, PEN, PPQ, UNACE and Frente Guasu; all other lists and mixed alliances in Other. No coalition vote is split among constituent parties. An interval is withheld if either election has no list mapped to an explicit named group. This is aggregate share change, not individual voter switching. Event review: Actual-event and/or comparability review incomplete

Current government and control: Unverified. Local government-risk forecast: unassessed.

Polling: no vetted current evidence included for this office.

Municipality matched by department and name, with documented abbreviation/rename bridges. Historical numeric district codes are not stable. This is an identity bridge, not proof of unchanged boundaries. Replacement archive runs through November 2025; later events/current control require verification.

Registry and evidence links: Source 1

Electoral event evidence

Separate source records can belong to the same election cycle. Recounts, runoffs and void returns do not create additional cycles.
