Scratch notes — canonical plan lives in QA_PLAN.md §7 PHASE PLAN.

Local-dev environment quirks (from Phase 1 investigation)

1. middleware.ts does not execute in local dev (.next/server/middleware-manifest.json is empty). Legacy numeric slug redirects still work because the same logic is duplicated in getStaticProps inside src/pages/uxcore/[slug].tsx and src/pages/uxcg/[slug].tsx.

   Worth investigating someday: is the duplication intentional belt-and-suspenders, or did middleware silently stop working and nobody noticed because the duplicate covered for it? If middleware is truly broken everywhere, you have one active implementation instead of two.

2. / returns 404 in yarn dev because no pages/index.tsx exists and middleware's / branch doesn't fire locally. Production serves / via deployment infrastructure (reverse proxy or similar). Not an app bug — but the local dev experience is broken. Consider creating a minimal pages/index.tsx that renders a home page so local dev mirrors production.
