Action Reference

Every direct action accepts one option object and returns a new immutable ChartProgram. Choose a task family for readable behavior, defaults, inference, and errors; use the exact lookup when you already know the action name. H0–H4 are catalog role tags, not grammar levels or trace depths. An action’s relative hierarchy comes from the smaller actions it composes. The API-layer labels user-facing, advanced, and primitive independently describe exposure.

Exact action lookup

Use document search with Ctrl+K, or filter the alphabetical list by action name, API layer, or domain. Each action has one canonical family entry.
