  90T4 (Recognition Forcing): Recognition requires distinguishing states.
  91A configuration where all entries are identical contains zero information
  92and cannot support any recognition event. This is the RS formalization
  93of "nothing cannot recognize itself" (MP/T1) applied to configurations:
  94a uniform ledger is informationally equivalent to nothing.
  95
  96The derivation:
  97  T4 (recognition requires substrate) + T1 (nothing has infinite cost)
  98  → at least one entry must differ from the ground state
  99  → the configuration is non-trivial
 100
 101This replaces the old T6_Requirement structure with a THEOREM. -/
 102
 103/-- A configuration is **non-trivial** if at least one entry differs from 1.
 104    Equivalently: the configuration is not the uniform ground state. -/
