Coherence C[χ] = S_max - S[χ] (organized information density).

Show coherence cannot be defined as entropy deficit. Find a system where C[χ]=0 but meaningful organization exists. Demonstrate S_max is ill-defined for the universe.

S_max for the entire universe may be undefined or infinite. Bekenstein bound gives local S_max but not global. This is a genuine formal gap.
