C073Vacuum and cosmology
Removing a common energy offset from normalized probabilities does not yet determine its gravitational effect. Comparing DTT with quantum field theory vacuum, this article derives the effective cosmological-constant combination, identifies the finite parameter that remains free, and shows what a source mechanism would need to fix for a stable physical explanation.

A vacuum response can be insensitive to an additive energy offset while gravity remains sensitive to it. This is the central issue when comparing DTT completion models with the cosmological constant problem. A finite spectrum or a normalized transition law can be useful without yet explaining the gravitational effect of vacuum energy.
