History and evidence
We publish the sources we have and do not fill gaps by assumption.
432 Chamber Orchestra was founded in November 2013. The Foundation was registered on 8 January 2018. The public history includes 10 concerts in Sofia, but the event-level catalogue is incomplete.

Documents
The public copy of the Founding Act is in Bulgarian and has been irreversibly redacted to remove personal identifiers and full residential addresses.

What remains missing
No complete public catalogue currently provides a date, title, venue, programme, participants and source for every concert. These fields will not be published until supported by reliable archive documents and clarified rights.
- Exact event dates and titles
- Venues and programmes
- Participants and publication consent
- Rights and provenance for photography, audio and video
- Archive-completeness review
