## Problem 077 — rank:132

**Title:** Three-dimensional tissue reconstruction

**Added binding assumptions (LaTeX):**

```latex
Correct the missing backslash in $\widehat X$ and define the quotient discrepancy as $\inf_{g\in\mathcal G}\|\widehat X-X\circ g\|_{L^2(\Omega)}$, with the permitted action and volume convention fixed. Depth interpolation needs a quantitative smoothness bound; in-plane landmarks alone cannot identify tissue changes between absent sections. Distinguish uncertain deformations from genuine section-to-section biological variation.
