Full round-trip checklist for adding or changing a construct that crosses the Python↔JS bridge as serialized IR — a new operator, mark, builder method, or coordinate transform. Use BEFORE implementing such a construct; missing a step fails late (at parity-render or CI, not at JS build).

Render a GoFish Storybook example to an image, look at it, and fix mistakes in a feedback loop. Use when authoring or debugging a chart example/story and you want to visually verify and refine the output (not just edit the code blind).
