Structural failure
Open and recurrent sectors require mutually incompatible underlying rules, or complete U / Compat cannot support persistent recurrent classes.
Evidence discipline
Validation & Falsification
Known physics is used as calibration and constraint — not as hidden input to the fundamental mechanism.

Falsification criteria
Spectrum failure
The observed particle spectrum cannot arise from admissible recurrent classes even after a fully specified microscopic model is constructed.
Gravity failure
Observed gravitational behavior requires a source fundamentally unrelated to the bound-energy mechanism used by UGSD.
Quantum failure
Observed probabilities or contextual correlations require a weighting structure incompatible with the same relational composition rules.
