## Problem 306 — rank:198

**Title:** Integration of the mitochondrial endosymbiont

**Added binding assumptions (LaTeX):**

```latex
For a finite-state model, specify the finite grid or enumerated allowed values of the apparently continuous descriptors and the error of that coarse representation. The transition step is an evolutionary-event convention unless calibrated to physical time. Fix the initial state and full transition law, and report the positive-probability no-integration outcome by $H$. The first-passage calculation is standard for a known matrix; historical calibration and shared necessary features are the research targets.
