+## ERR-083 | Commercial Next production build terminates before artifact generation | active 2026-07-19
+`frontend` local `npm run build` ends during Next.js 16.2.10 compile/static generation, both without configuration and with the CI Supabase placeholders. It leaves no `.next/BUILD_ID` or `.next/prerender-manifest.json`, and no application stack trace. Frontend contracts (`270 passed`), lint, and the selected Python commercial workflow regressions (`128 passed`) remain green.
+
+Prevention: do not equate this local host failure with an astrology capability regression. Treat GitHub Actions Node 22 build evidence as the deployment gate before merge. Keep VedAstro `premium_key_missing` and official raw snapshot status explicitly degraded.
