Introduce `IsKMSStateForFlow.exists_gns_unitary_strongContinuous`, which shows that a KMS state at inverse temperature β > 0 for a one-parameter Killing flow on a region B yields a GNS triple carrying a strongly continuous unitary group implementing the flow. The proof routes through `IsKMSState.invariant_of_pos` (KMS invariance) and the abstract `exists_gns_unitary_of_invariant_strongContinuous` construction, with the ℝ action packaged via `Multiplicative ℝ`. The corresponding blueprint theorem is added and marked `\leanok`.

…ocal alge…

- Introduce `eq_zero_of_commute_of_cyclic`, an abstract lemma showing that an operator commuting with a cyclically-spanning set and annihilating the cyclic vector must be zero.
- Use it in `localVonNeumann_separating` to prove that, given cyclicity of Ω for R(B₁), any R ∈ R(B₂) with RΩ = 0 vanishes, leveraging curved microcausality to obtain the required commutativity.
- Add the corresponding blueprint theorem with `\leanok`, dependencies on curved microcausality and the cyclic-vector definition.

…hesis

- Introduce `eq_zero_of_commute_of_cyclic`, an abstract lemma showing that an operator commuting with a cyclic set and annihilating the cyclic vector must be zero.
- Add `localVonNeumann_separating` as a Minkowski corollary: cyclicity of Ω for R(B₁) (the Reeh-Schlieder input, taken as an explicit hypothesis) implies Ω is separating for the spacelike-separated algebra R(B₂), via microcausality.
- Document both results in the blueprint with a new Statistical Independence theorem node, noting that cyclicity is a hypothesis here to mirror the curved-spacetime setting where no spectrum condition is available.
