H6 Decoherence And Source Response

H6 asks whether classical spacetime can be understood as the structure left after alternative pulse histories decohere. H6S1 asks how a quantum source might source a gravitational response in a weak-field diagnostic setup. H6S2 asks whether a candidate response may depend on an arbitrary ensemble decomposition of the same local source density operator. H6S3 proves that branch-dependent probe variance is not physical without records, a stochastic classical pulse-geometry law, or a non-classical geometry or mediator route. H6S4-C tests the stochastic classical route as a finite pulse-potential diagnostic. H6S4-Q tests the non-classical mediator route and recovers standard finite quantum mediator structure as a conditional derivation. H6P1 tests the best Pulse-native closure-response principle and ends as a finite diagnostic, not a source-response law.

Current Verdict​

H6 is accepted only as bounded branch-decoherence bookkeeping and model comparison. H6S1 is a useful executable quantum source-response diagnostic. H6S2 is a diagnostic ensemble-decomposition-invariance admissibility filter with a clean no-go subtheorem for unsupported spacelike branch response. H6S3 is a diagnostic no-free-branch-variance theorem and route ledger. H6S4-C is a diagnostic finite stochastic pulse-potential comparator. H6S4-Q is a conditional derivation of known finite quantum mediator structure in Pulse Model record language. H6P1 is a diagnostic finite closure-response contract. None of these supplies a full classical-spacetime emergence theorem or a physical source-response law.
