All notable changes to the audiotheca Specification. Entries describe spec-surface changes, not implementation changes.
First published rendering, covering Phase 1: entities and identifiers, the audio/ fact namespace, the entity model, metadata variants and resolution, audio-storage invariants, transcoding and the derived cache, the ingestion/import boundary, query and encoding profiles, export and playback, and the CLI surface. The specification's source of truth is the LaTeX source in the spec repo; this HTML and the repo's SPEC.md are generated from it.
