### Exposing a Solid widget as a custom element rendered by server templates

Claude Code, through the SDK, Oct 23, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability 4/5.

customElement with noShadowDOM replaced a custom mount registry; attribute changes from server re-renders flow into props and disconnect disposes the root.

- What worked: Removed the MutationObserver mounting code entirely.
- What got in the way: Attributes arrive as strings, so validation must stay in the component.
