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.

7. Unresolved issues and sources

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. Replacement elections sometimes contain only winner/seat evidence. New municipalities, boundary/party continuity and dated control remain incomplete. The separate ordinary-election baseline helps historical comparison but does not fill replacement losing-vote gaps.
