Known metadata gaps
Recorded explicitly rather than guessed.
- publishedYear: the animation landing page carries no publication date.
- authors: issued by the facility without individual authorship.
- Lineage unresolved. This is explanatory writing that restates findings published elsewhere, and it names no sources Lithoen could follow. Every claim resting on it therefore has an unresolved evidentiary origin, and independence between it and any other source is UNKNOWN.
