history and migration notes

Prefer the system prompt plus one relevant component schema. Retrieve a nearby

example or the relevant reference section only when needed; do not load the

complete schema, examples, and reference by default.

## Package Entry Points

Use family subpaths for chart code: `semiotic/xy`, `semiotic/ordinal`,

`semiotic/network`, `semiotic/geo`, `semiotic/realtime`, `semiotic/physics`, and

`semiotic/value`. Use `semiotic/ai` or the lighter `semiotic/ai/core` for

generation and validation helpers, `semiotic/server` for static rendering,

`semiotic/recipes` for custom layouts, and `semiotic/themes` or

`semiotic/utils` for shared utilities.

Validate generated configurations with `prepareChart`,

`npx semiotic-ai --doctor`, or the MCP diagnostic tools. When a renderer is

available, confirm non-empty render evidence and run the accessibility audit.

+ These checks do not authenticate sources or establish usability with actual

+ readers. Source task packets label their content identity; verify the installed

+ package separately before applying current-development guidance.
