A sidecar is a markdown file that serves as a metadata envelope for an artifact that cannot be represented directly in markdown — typically a video recording, audio file, slide deck, or PDF. The sidecar makes the artifact discoverable in the knowledge graph without embedding binary content.

recording.sidecar.md, slides.sidecar.md). The .sidecar.md suffix distinguishes these from content files.Archives/ subfolder.artifact:: predicates for each binary (e.g., artifact::Archives/recording.mp4). Non-local artifacts use the Source Repository + Public URLs pattern instead.Archives/ subfolder within the compound folder. The sidecar is the committed, searchable proxy.For non-local artifacts, the sidecar records the source repository and public URLs rather than storing a local copy. This avoids duplicating large files while keeping the reference in the graph.
