Executable behavior truth

Definition

When an open-source editor repo exposes both docs and tests, executable tests are often the stronger evidence for real behavior.

Why this matters

Docs describe intent or public API. Tests describe what the system actually enforces.

Current research conclusion

Milkdown is the clearest example of this in Plate's editor-reference stack.

For Milkdown:

• e2e and unit tests are strongest for behavior
• docs are strongest for package ownership and API surface

Use

Use this concept when deciding how much weight to give:

• tests
• docs
• examples
• storybook

inside an open-source reference repo.
