Applied @next/codemod migrations: - middleware-to-proxy: src/middleware.ts → src/proxy.ts + function rename - remove-experimental-ppr: no hits - remove-unstable-prefix: no hits tsconfig.json picked up Next 16's autofixes: - jsx: 'preserve' → 'react-jsx' - include .next/dev/types/**/*.ts (dev-mode route types) - next-env.d.ts: triple-slash reference → ES import (TS 6 / Next 16 style) eslint-config-next@16 ships a native flat config, so dropped the @eslint/eslintrc + FlatCompat shim. eslint.config.mjs now imports eslint-config-next/core-web-vitals + eslint-config-prettier/flat directly. Note on ESLint 10: bumped + reverted. eslint-config-next@16 still has a transitive eslint-plugin-react@7 that uses the eslint-9 context API (getFilename on context); breaks under eslint 10. Audit anticipated lockstep — but the transitive isn't ready yet. Holding at eslint 9.x until upstream lands. Tracked in BACKLOG. React Compiler safety rules (react-hooks v7) shipped with config- next 16 surfaced ~89 legitimate findings (set-state-in-effect, ref-during-render, immutability). Demoted the new rules to `warn` so the codebase isn't blocked; triage tracked in BACKLOG §G. Verified: tsc 0 errors, eslint 0 errors / 105 warnings (89 new Compiler-rule warns + 16 pre-existing), next build clean, custom server build clean, vitest 1315/1315.
