 215/-! ## RSReal: Existence in the Discrete Configuration Space -/
 216
 217/-- **RSReal**: A value x is "real" in the RS sense if:
 218    1. RSExists x (stable under J)
 219    2. x is in the discrete configuration space (quantized)
 220
 221    For now, we model discreteness as being algebraic in φ. -/

 232/-! ## The Meta-Principle as a Physical Theorem -/
 233
 234/-- **MP_PHYSICAL**: The Meta-Principle "Nothing cannot recognize itself"
 235    as a theorem about cost.
 236
 237    In the CPM/cost foundation, this is DERIVED, not assumed:
 238    - "Nothing" (x → 0⁺) has unbounded defect
 239    - Therefore "nothing" cannot be selected by cost minimization
 240    - Therefore "something" must exist (the unique x=1 minimizer)
