Theory timeline
The 23 theories of the corpus laid out along the years of their currency. Bar color reflects support tier. The dataset is the period field on each theory in codex/theories.yaml; gaps between bars reflect the corpus's reading of when a theory was actively advanced, not its full intellectual history.

Theories are sorted by support tier, then by score within tier. The tier-4 bars are the orphan set;
they remain advanced as positions but the corpus has not (yet) attached evidentiary anchors to any of them.
The vertical scan reveals what mid-20th-century theories survived to the present
(extraterrestrial, demonic, black-projects) and which contemporary frameworks are still consolidating
(AI / non-biological intelligence, apparatus-response).
