Researchers have introduced TwistedMerge, a novel pipeline for certifying and abstaining from model merging. This method formulates merging as a descent problem, treating checkpoints as local objects and alignment maps as transitions. TwistedMerge separates fixed-chart averaging, gauge inconsistency, central obstructions, and nonabelian holonomy to ensure global consistency. The pipeline promotes a residual to a cohomology class only after rigorous inverse-consistency, coefficient-identification, centrality, and closure tests; otherwise, it abstains and returns a fallback. Theoretical proofs demonstrate error-control theorems and refinement tests for comparison-complex sensitivity, while empirical results show TwistedMerge's stability and ability to distinguish between certified and uncertified merges.
