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

ONPE geography matched on full named hierarchy; original electoral codes retained. Municipal votes are shared mayor–council slate ballots; seats require JNE proclamation. The 3,085-entry INEI 2026 municipal directory and one unresolved 2025-only entry are tracked separately from RENIEC’s 3,382 electoral rolls. The complete named 2026 local call register and three-cycle vote/seat archive remain unavailable. Manitea Alta is bridged to its new district/code. Valle Nazarategui’s omission requires legal reconciliation. Five malformed 2022 source units, full seat proclamations and current control remain incomplete. Pión’s final annulment and Ninabamba’s final 2025 result are resolved.
