# Pattern workflow requirements

1. When creating a new pattern under `led-driver/src/patterns/`, also add/update a corresponding test file in `led-driver/tests/patterns/`.

2. When adding a new pattern, ensure led-controller has `db/pattern.json`; if it does not exist, create it. Add the new pattern metadata and parameter mappings there.

3. When adding a new pattern, add at least one test preset entry in `db/preset.json` in led-controller that uses the new pattern.
