EXECUTED ACCEPTANCE RECORD
Isolation envelope checks
The selected supports were evaluated at 32 mass, CG, stiffness and damping corners. These records evaluate the executed numerical files, verify their provenance and preserve the rejected stiff alternative.

Scope
Each support group represents two physical mounts assumed to share load equally. The combined transient envelope adds the separate peak runup and base-pulse effects, with a 1% peak allowance. It bounds their relative phase within this linear model. It does not solve nonlinear contact or material behavior. A rejected design is retained as evidence of the criterion, not presented as acceptable operation.
Reproduce the numerical runs first with python run.py, then audit the results with python complete_validation.py.
