Compositional Defiguration is the founding specification of the Surface Weather Station, an MMRS instrument for measuring how a scholarly corpus appears across search engines, AI summaries, indexes, mirrors, and other public composition surfaces.
The method begins from an expected figure for each tracked object: its name, provenance, definition, hierarchy, canonical anchor, and essential relations. It then compares that figure with what the public surface returns. The difference is not treated as a single question of whether a page is indexed. It is decomposed into five signals:
From these signals the specification derives Link Fade, Ghost Survival, Compositional Defiguration, Compositional Bystanding, Composition Eligibility, and the Scale Drift Index.
The instrument distinguishes a work that is absent from one that is visible but distorted, a concept that survives through dead anchors from one installed in current custody, and exact-string retrieval from genuine field-level adoption. It also introduces three enduring diagnostics: successor-anchor lag, chronological smear, and source-hierarchy inversion.
Version 1.0 is the conceptual genesis of a measurement system later calibrated through multiple substrates and repeated scans. It transforms public visibility from anecdote into an inspectable research object.
