**Title:** Partially identified event order in eukaryogenesis

**Added binding assumptions (LaTeX):**

```latex
The displayed support thresholds are pairwise, not a simultaneous credible ordering, and combining high-support pairwise relations can produce an inconsistent set. For a jointly supported acyclic partial order, choose a posterior graph set of mass at least $1-\alpha$ and retain only precedences shared by every graph in that set. Repeat across the declared model/prior family. A robust partial order is not a uniquely identified chronological narrative.
