• Witten's no-boundary-as-universal-vacuum conjecture is a third, separate strand from the Curiel/Ferreiro-Cavallaro semiclassical-gravity cluster

• Witten/CLPW's no-boundary-state strand and the Curiel/Ferreiro-Cavallaro matter-spacetime-divide strand never cite each other and share no authors, only common QFT-in-curved-spacetime background references

• CLPW's 'gravitational dressing to an observer's worldline' is a crossed product of a Type III von Neumann algebra with its modular automorphism group, yielding Type II

• Ferreiro and Cavallaro (2026) extend Lehmkuhl's 'egalitarian' reading of GR: in QFT on curved spacetime the metric gains material significance alongside its geometric and gravitational ones

• Ferreiro and Cavallaro (2026): splitting total stress-energy into 'gravitational' and 'matter' parts needs a vacuum choice generic spacetimes lack, producing a dilemma that collapses the classical matter/spacetime divide
