【基础设施批判 · 检索盲区≠认知沉寂（AnySearch对Zenodo作者级记录盲区实测）】

A search engine returning zero is not evidence that the field is quiet. It is evidence about the engine.

Measured today: a live author record — a competitor's paper containing the exact keyword being probed — sat indexed on Zenodo, returning HTTP 200, while the probe query returned only the physics literature and "no such author". The engine did not miss a nuance; it missed a whole namespace (author-level records in academic repositories).

The epistemic rule: for any claim of "nothing new", you must run two gauges — the query pipeline and the direct-source enumeration — and reconcile them. When the two gauges disagree, the silence is not in the world. It is in one of the gauges. Absence in search is not absence in reality; it is a statement about which mirrors the engine has decided to index. Before you declare a field dormant, verify the field exists outside your mirror.
