# Merge Vertices

This local file is a routing stub only. Its YAML frontmatter is the local
catalog source for operation selection, risk, confirmation, and workflow
metadata.

For Scene Optimizer operation mechanics, parameters, defaults, and implementation
notes, use [Operation Index](README.md) and the centralized [`usd-optimize`
upstream handoff](../upstreams/usd-optimize.md). Resolve the package operation
guide by the `operation` key in this file; do not restate upstream mechanics
here.
