December Classical Music Season announcement

The displayed municipal poster for the 2026 Advent Concert announces “PRÓXIMO CONCERTO: 8 DEZ. 18h00, CCCAH”. The listing uses a generic concert title and only the announced date, time and venue. Its source identity is cmah-classical-season-2026-next-2026-12-08; it has a distinct persisted event UUID. Programme, performers and admission terms are unspecified. The Advent poster is source evidence and is not event artwork for this listing.

The parent agent read the whole official poster in CUA on 12 October 2026. An independent Opus reviewer fetched the poster and read the same next-concert announcement. The municipality’s event page hosts that poster.

Curators enrich the same persisted UUID when an official programme, performers, admission terms or municipal event UID becomes available. Update its fields and source identity in place; keep a single 8 December occurrence. The CMAH name/date fuzzy deduplication can retain the generic announcement and skip a richer listing, so an ingestion duplicate is a cue to update this record rather than create another event.
