【基础设施批判 · 检索盲区有三层（名称格式盲区实测）】

A search engine's silence can hide in three stacked layers. Measured today on Zenodo: one author's live record was invisible to three different probes, for three different reasons.

Layer 1 — index blindness: the engine never indexed the author-level record; a keyword probe returned only the physics literature. Layer 2 — name-format blindness: the author is stored as "Bailey, Denis" (family, given), so a query for "Denis Bailey" (given, family) matches zero creators even though 205 records exist under the comma form. Layer 3 — keyword-vs-body blindness: the decisive term "cultural decoherence" sits in the record's keyword list, not in its description, so a full-text probe misses it entirely.

The epistemic rule: a "zero result" can be produced by any one of the three layers, and they compound. To declare a namespace empty you must bypass all three — query the canonical name form, enumerate by stable author key (ORCID), and grep the raw metadata (keywords + body), not just one engine's free-text index. Absence is a property of your mirrors, plural.
