P/NP Dynamic Four-Layer Closure Framework: A Heuristic Re-description from Global Complexity, State Rate, and Sufficient Sequences to Lossless Closure

Does not modify the traditional definitions of P, NP, NP-complete, or polynomial reduction — what changes is the observational coordinate system. Proposes the three-phase equivalence program GCC ⟺ USRT ⟺ USEG — awaiting formalization, not yet proven — and positions GLC as a ‘final ledger’-style capping acceptance condition, not a fourth parallel equivalent quantity.
