Quantization Corridor from Action Pressure: Soft Selection, Phase-Weighted Accumulation, and the Born Slot

Quantum structure follows from refinement-stable bookkeeping, not postulates. Soft selection is forced when corridor-level action ties make hard selection require forbidden tie-break (micro-history) data. The corridor therefore retains all admissible configuration classes and aggregates them using action-only weights. Interference stability pressures a phase-bearing carrier, concatenation stability pressures exponential phase weights, and gauge-meaningful scalar prediction forces quadratic magnitude extraction (the Born slot). No Hilbert axioms, path-integral primitives, or calculus limits are assumed.
