Causal Quantum Gravity

This document is an operational protocol: input a causal delay kernel Dij and output numericalobservables. [STD] Observables are compared against standard GR/QFT-in-curved-spacetime targets (dispersion, particle creation, Hawking temperature). [CMP] Novelty is only the closure layer:admissibility constraints + a deterministic selection functional that replaces vacuum-choice freedom.Validation is by agreement/disagreement of observables under a fully recorded run identity.
