## Problem 216 — rank:287

**Title:** Hospital-transmission reconstruction

**Added binding assumptions (LaTeX):**

```latex
Because $G$ is a random latent transmission forest in the generative model, the displayed guarantee is coverage of a latent-object prediction set, not automatically a confidence set for a fixed parameter. Specify whether coverage is marginal over outbreaks or conditional on observed onset information. Include external-source multiplicity and unsampled intermediate episodes consistently; two identical source signatures can remain indistinguishable even with a well-resolved sequence genealogy.
