Polyxd 0.4.0

Every package moves to 0.4.0.

New on npm

• @polyxd/runtime: generates a UI document for an ask with the model you choose (Claude, OpenAI, Gemini or a local model), applies your Design Direction, checks and repairs the answer, streams, and remembers screens on the client. Runs in Node, browsers and Cloudflare Workers.
• @polyxd/mcp: an MCP server. The chat app's own model writes the screen; Polyxd checks it and shows it in the chat as an MCP App, in any of 25 design systems and templates. npx -y @polyxd/mcp, or connect to the hosted server at https://mcp.polyxd.com/mcp. Listed in the MCP Registry as com.polyxd/mcp.
• @polyxd/server: the runtime behind an HTTP API with streaming, and a Dockerfile.

Changed

• @polyxd/spec ships its validators compiled ahead of time: no code generation at run time.
• @polyxd/verifier/static: the document checks without Playwright.
• The renderer keeps people's initials visible on a selected row.

The spec's document format stays 0.3.0. Docs: https://polyxd.com/docs/
