Milkdown behavior map

Purpose

This page maps Milkdown into reusable research lanes for future agent work.

It bridges:

• the upstream raw clone at ../raw/milkdown/repo
• the raw entrypoint in ../raw/milkdown
• the compiled Milkdown source pages in docs/research/sources/milkdown
• the existing editor-behavior law stack

Source clusters

Executable behavior lanes

• behavior-test-lanes.md

Covers:

• input tests
• shortcut tests
• transform tests
• unit tests

Package and docs ownership lanes

• docs-and-package-surface-map.md

Covers:

• docs/api ownership
• package layout
• public package surfaces

Why this is better than the old setup alone

The older repo-safe inventories were already useful, but they were still inventory-first.

This map plus the compiled source pages now make Milkdown usable as a reusable research surface instead of a fork pointer plus TSV pile.

Current role in Plate

Milkdown is:

• the main open-source cross-check
• the executable companion reference
• the architecture/productization cross-check

It is not the primary markdown-native product authority.
