  "observationModel": "Independent, additive, zero-mean Gaussian noise on each paired density difference; no process noise or unknown spatial material parameters.",
  "fit": "Least-squares contractility grid 1..5 in increments 0.25, using only calibration observations. All other parameters fixed at the documented defaults.",
  "passiveCandidate": "Zero active stress, same diffusion, turnover and known initial density. The ideal active-stress intervention leaves this candidate unchanged, so every paired response is zero.",
  "limitations": "Two specified candidate families only; intervention specificity and known initial conditions are assumed. A causal response alone does not identify molecular reactions. Eight realizations per noise level do not establish a general error rate.",
