Preregistration: Blind Coding of Mechanism Classes in a Spectral-Exponent Survey (172 Measurements)

Preregistration of a blind-coding study: three independent, blindedraters classify 172 time-series descriptions by the relation of themeasured quantity to the underlying system (direct output, accumulatedstock, step difference, model residual, outside). Hypotheses, consensusrules, exclusion criteria, and the analysis plan are fixed in thisdocument before coding begins; the underlying measurement table ispinned by its SHA-256 hash. Results will be published regardless ofoutcome. Files in German (authoritative) and English. Study protocol and document drafted in collaboration with Claude (Anthropic); the author bears sole responsibility for the content
