Provenance records
This index is an experiment in structured metadata, content-addressed publication and visible version history.
Scope
A smaller public collection
The public index presents Tom Jackson’s September 2026 note as the current record. Earlier experimental media and source material are preserved in the repository.
A content address can show whether retrieved material matches a published version. It does not by itself prove authorship, guarantee continued availability or replace a fuller provenance and signing model.
