Milkdown is the primary open-source cross-check

Question

Which repo should be Plate's main open-source companion reference for markdown-first behavior and architecture cross-checking?

Decision

Milkdown wins.

Why

• it is already cloned locally
• it has a rich mix of tests, package surfaces, API docs, examples, and stories
• it exposes markdown-first presets and transformer seams clearly
• it is more useful as a cross-check than as a primary authority
