## Statements (checkable)

1. The total image size limit remains 15 GB.  [✓0 ✗0]
2. Vercel names custom Vercel Sandbox environments for coding-agent evaluations as a use case; images are pushed with vercel link, vercel vcr login docker and vercel vcr build docker . --push.  [✓0 ✗0]

## Fix

Layers between 500 MB and 2 GB compressed no longer need to be split for Vercel Container Registry; keep each compressed layer at or under 2 GB and the whole image at or under 15 GB.
