## Problem 229 — rank:177

**Title:** Quantitative completeness of cytotoxic-lymphocyte self-protection

**Added binding assumptions (LaTeX):**

```latex
Separate uncertainty in the finite-panel population probabilities from model discrepancy using simultaneous replicate-based bounds. Standardize self and target comparisons to the same exposure and context law while retaining cell-type-specific measurement differences. Residual prediction error does not uniquely identify a missing protective mechanism. The narrowed question tests quantitative completeness of known variables; it does not deny that experimentally supported self-protection mechanisms already exist.
