What this work contributes
Studies restrictions on negative energy averaged along specified trajectories in quantum field theory. It also treats differences from a Casimir vacuum background, illustrating why boundary conditions must be stated when applying bounds.
Where the evidence stops
Do not claim every static Casimir negative-energy region must disappear after one universal time limit. The field, state, sampling, trajectory, spacetime, and background determine the applicable inequality.
