Adds complete validated metadata rows for the three previously unindexed Standard files. Local inbox SHA-256 values match the Hub LFS identities exactly; container and stream metadata were extracted from those matching bytes. Canonical coverage is now 338 rows for 338 direct Standard MP4s, with unique IDs and hashes. Adds a reproducible three-row additions source and updates counts and validation. No video payload is uploaded, modified, moved, or deleted.
Enforce provenance exclusion and reconcile active indexes
Removes one non-distributable Pre-Standard metadata row from the active public index without uploading or identifying the excluded holding. Corrects counts to 129 Pre-Standard records, documents 3 direct Standard files pending metadata ingestion, and extends validation to reconcile both indexes with the repository inventory. No video files are added, modified, moved, or deleted.
Metadata-only release candidate based on 339e6149de130cbe2d001f7a0e5247872bc788ec. Adds stable record IDs, normalized schema, validation and repair tooling, clearer coverage and limitations, rights and privacy notes, and a documented Viewer migration plan. No video files are modified.
