Source-reported control: Unverified. Current tenure requires separate dated evidence.

5. Officeholder evidence

Dated roster observations are not automatically current tenure. The source current-office flag means this office is tracked now, not that the last winner still holds it.

No officeholder observation supplied.

6. Polling context

No local poll supplied.

National context is listed on the polling page. It is not a local forecast.

7. Unresolved issues and sources

Expected ordinary election on the last Sunday of October; formal call and 2027 roster require refresh. CEDE/Registraduría ordinary returns V2. Shares exclude blank and invalid ballots. Changing coalition labels and current control are not harmonized. Repeats, annulments and opposition-seat acceptance require certification review. Six 2023 assemblies remain absent: Amazonas, Guainía, Huila, Risaralda, Vaupés and Vichada. Cali’s 37 JAL boards and dated membership rosters are registered; the national JAL register, three-cycle votes and replacement-event final returns remain incomplete. Twenty mixed-list-type histories, Bogotá and Cali 2015 partial counts and candidate/elected-flag inconsistencies require reconciliation. The national historical portal rejected this browser through security screening. Full legal seat allocation is separate from candidate flags and directory headcounts.
