## Prompt

TIER CLASSIFICATION SYSTEM — META-PROOF
Formally define and justify the Tier structure for all v1.27.5 predictions: Tier A-star (zero free parameters, <1% PDG deviation), Tier A (zero parameters, >1% deviation, known correction identified), Tier B (one derived parameter), Tier C (parameterized, algebra motivates form). List all observables under each Tier. Assess whether the Tier system itself is a falsifiable framework. #SuperGrokTOE #TierClassification
