## Problem 060 — rank:129

**Title:** Principled model reduction for living systems

**Added binding assumptions (LaTeX):**

```latex
Specify a shared parameter-reduction map $\vartheta=R(\theta)$ and write the reduced trajectory with that parameter. A single fixed $\vartheta$ for all full-model parameters is a much stronger, separate requirement. Bound the regularity and description complexity of $P,f_r,h_r$ to exclude arbitrary encodings. Uniform analytic error and test-distribution statistical coverage are alternatives, not equivalent guarantees.
