Effective Carrier Routing, Control Work, and Stress in a Finite WRRA Model

We construct an effective carrier model within the Worldline–Residue–Resource–Action framework. Two conditionally independent registers encode prime-factor multiplicities. A label-symmetric equality projector controls a common source coupled to two supplied particle-pair channels. One pulse generates the earlier collision-statistic probabilities without address-dependent interaction strength. A restricted single-register obstruction and a classification of diagonal permutation-invariant effects specify the construction’s resource assumptions. The implementation reproduces species probabilities, but not the preceding interface’s coherent output channel. Bare-energy conservation holds at the calibrated reference volume; detuning away from resonance requires interaction energy and switching work. A response identity relates the reference pressure-volume moment to the logarithmic-volume derivative of mean pulse work. Composition with the implemented muon-decay kernel recovers energy and pressure histories at full conversion. This is an executable effective interaction candidate and compatibility analysis; lepton identities, weak interactions, and the full fifteen-channel carrier are not derived from arithmetic alone.

The 123 carrier-level checks are internal consistency checks, not experimental validation or external journal peer review. The manuscript was prepared before this deposit; its preparation-time statement that no public DOI had been assigned is superseded by this record.
