Release record

CP6 — Production Readiness

Production hardening and release verification for the Engineering Lab.

What changed

The Engineering Lab completed its production-readiness pass without changing the Astro architecture or adding paid infrastructure.

  • The production build generates the complete current route set successfully.
  • Shared metadata, canonical URLs, indexing behavior and keyboard focus hardening from CP5 are carried forward.
  • The browser quality audit now discovers and checks every generated HTML route instead of relying on a fixed sample list.
  • GitHub Actions runs the production build and browser audit using the existing free GitHub-hosted workflow.
  • A generated XML sitemap and explicit robots.txt now provide a small, durable crawl surface for the public site.
  • Vercel deployment status for the current production checkpoint is verified successful.

Release boundary

This checkpoint keeps the Lab deliberately static and maintainable: no CMS, database, analytics dependency, paid API, authentication layer or client-heavy application system was introduced.

The stable v1.0.0 history remains preserved. CP6 is a forward production-readiness checkpoint, not a rewrite of the original release.
