Scope

This is an independent mathematical construction under specified quantum semantics. Density operators, completely positive channels, Lindblad dynamics, and Born probabilities are assumptions, not conclusions derived from a measurement-strategy characterization. No earlier landmark manuscript is a formal premise of the proofs.

The spin-chain and oscillator constructions are distinct models. Neither is identified with a gravitational mediator, quantum field, microscopic evaporation channel, or characteristic-product coefficient. Documentary programme restrictions are recorded separately in Appendix app:scope.
