MATAMBÚ — Syndic and district council — shared ballot

All 1,973 imported 2016/2020/2024 returns now reconcile seats against 18,155 named elected people, including vice-officers and substitutes. The missing Cartagena 2020 result and eight spelling joins are recovered. Final proclamations replace 17 initial seat allocations. Fifty-two party-acronym joins are explicitly inferred and documented. New-canton predecessors stay separate; replacements, the 2028 call and current incumbents remain to be verified.
