Milkdown editor-behavior priority map

Purpose

This page says which Milkdown lanes matter most for Plate behavior work.

Tier 1: direct behavior lanes

These are the highest-value lanes to read first:

• e2e/tests/input/*
• e2e/tests/shortcut/*
• e2e/tests/transform/*
• packages/plugins/preset-commonmark/src
• packages/plugins/preset-gfm/src
• packages/plugins/plugin-indent/src
• packages/transformer/src/parser
• packages/transformer/src/serializer

Why:

• this is where executable behavior lives
• these lanes expose typing, shortcuts, transforms, and markdown package seams
• they are more useful than README files when the question is behavior

Tier 2: package-local and product-layer support

These are important supporting lanes:

• package-local unit tests under packages/**/__tests__ and *.test.*
• docs/api/*.md
• e2e/src/*
• storybook/stories/*
• crepe e2e lanes
• plugin-automd e2e lanes

Why:

• package tests capture narrower behavior edges
• API docs show public surface ownership
• product-layer demos help connect tests to runnable examples

Lower-priority lanes

Usually not first-read for Plate behavior decisions:

• package README files
• CHANGELOGs
• repo governance docs

Useful later, not first.

First compile order

Recommended order:

1. e2e input / shortcut / transform lanes
2. preset-commonmark and preset-gfm
3. transformer parser / serializer
4. plugin-indent
5. package-local unit tests
6. API docs, examples, and storybook
7. crepe and plugin-automd product-layer lanes
