Claims vs mainstream

The claim

Ys is proven exactly as the most dramatic popular version describes.

Popular versions compress and heighten details. Primary reports, archaeology, or franchise canon (when fiction) are narrower than the legend that grows around Ys.

The claim

Any mystery around Ys must mean a cover-up or suppressed technology.

Mainstream view

Gaps in evidence are common in old cases and folklore. Missing files or open questions do not, by themselves, prove a specific secret conclusion about Ys.

The claim

Every skeptical explanation for Ys has already failed.

Mainstream view

Mundane readings (misidentification, hoax, natural process, literary invention) remain live options unless ruled out by strong primary evidence.
