Recipe: Build a family of editable workshop symbols
Source: https://x.com/excalidraw/status/2098412173999357971
Date: 2026-09-12T15:00:00Z
Environment: Node.js 22.14.0 · Excalidraw 0.18.1 · LinkeDOM 0.18.12
Status: adaptation-tested

Scope
The official Excalidraw restore and serializeAsJSON functions restored all native elements, preserved a shape-color edit through save/reopen, and retained the twelve groups and text labels. This was a headless format check.

Passed checks
- The scene contains 49 native elements in twelve distinct labeled groups.
- All symbol geometry fits its drawing area and shares one stroke color and width.
- A changed native shape color survived the official serializer/restore roundtrip; all groups and editable labels remained.
- The HTML preview contains the same scene data and renders all twelve symbol groups in a simulated document.

Limits
These functional symbols adapt the idea of a consistent editable family. They do not recreate the original autumn icons or AI computer-use workflow. Automated format and geometry checks are distinct from a real editor interaction or a visual usability test; neither the original prompt’s repeatability nor reader comprehension is established.

Method
Official @excalidraw/excalidraw 0.18.1 restore and serializeAsJSON exports were bundled temporarily for Node. LinkeDOM supplied document globals; an empty canvas context supported import-time capability detection. No canvas rendering or interactive editor check was claimed.
Starter test command: node --test scripts/test-build-starters.mjs
No account records or third-party artwork were used.
