Known metadata gaps
Recorded explicitly rather than guessed.
- publishedYear: the page carries no publication date, only the note that it was originally written for “The Green Frog News”.
- 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.
