The provided Lean source slice does not contain the module IndisputableMonolith.Cost.Ndim.Neutrality. Because the instructions restrict me to using only what is actually established in the supplied source, I cannot write a module-level guide, explain its purpose, or list its declarations.
The supplied canon covers other foundational topics such as RecognitionForcing, DimensionForcing (D=3 via Alexander Duality), PhiForcing (the derivation of the golden ratio from self-similarity), and the UniversalForcingSelfReference properties, but it lacks the N-dimensional cost neutrality code you requested.
