Initial sweep surfaced ~89 findings; categorical triage status as of 2026-05-12: -- `react-hooks/set-state-in-effect` (~49) — `setState` directly inside `useEffect`. Sometimes intentional (post-fetch hydration), sometimes a missed `useState` initialiser or derived-state opportunity. -- `react-hooks/incompatible-library` (~13) — React Compiler skipped a file because it imports a not-yet-Compiler-safe lib (commonly Zustand, dnd-kit, certain TanStack hooks). No action needed unless we want Compiler to run on that file. -- `react-hooks/refs` (~10) — `ref.current` read during render. Always a real bug if it influences the render output; fine if it's just for next-effect's stash. -- `react-hooks/immutability` (~7) — mutation of supposedly-immutable values (props, state). -- `react-hooks/set-state-in-render` (~5) — `setState` called during the render body, not from a handler/effect. -- `react-hooks/purity` (~2) — non-pure call during render. +- ✅ `react-hooks/purity` (2 → 0) — promoted to `error`. Cleared by pinning `Date.now()` reads to a `useState`-backed `now` ticker in `notes-list.tsx`. +- ✅ `react-hooks/set-state-in-render` (5 → 0) — promoted to `error`. `useMemo` mis-used for side effects in `interest-contact-log-tab.tsx`; converted to `useEffect`. +- ✅ `react-hooks/immutability` (7 → 0) — promoted to `error`. Mutable `useMemo` value in `documents-hub.tsx` drag counter → `useRef`. `let angle` mutation in `PieChart.tsx` slice loop → `reduce`. Three "function used before declared" hits (load/loadProfile in admin/onboarding-checklist + settings/user-profile + settings/user-settings) → declared inside the calling `useEffect`. +- ✅ `react-hooks/refs` (10 → 0) — promoted to `error`. Three `ref.current = x` writes during render moved into a layout-effect (`use-realtime-invalidation.ts`, `settings-form-card.tsx`, `inbox.tsx`). Three search-related `ref.current` reads during render rewritten to backed-by-state (`command-search.tsx`, `mobile-search-overlay.tsx`). Scan shell's `fileRef.current.files[0]` read replaced with a tracked `currentFile` state. +- ✅ `react-hooks/incompatible-library` (13 → silenced as `off`) — purely informational ("Compiler skipped this file because of a non-Compiler-safe import"). No action needed. +- ⚠️ `react-hooks/set-state-in-effect` (51 → still warn) — almost entirely the `useEffect → fetch → setState` data-loading pattern in admin-form components. Each call site refactors cleanly to TanStack Query (`useQuery`), but it's per-file mechanical work × ~45 files = focused half-day pass. Two hooks already migrated as templates: `use-is-mobile.ts` (→ `useSyncExternalStore`), `use-notifications.ts` (socket pushes via `queryClient.setQueryData` instead of local state). -All demoted to `warn` in `eslint.config.mjs` so the dep upgrade isn't gated on cleanup. **Triage as its own pass — ~30–60 min per category. Promote back to `error` once the bucket reaches zero.** Don't blanket-ignore: each warning either points at a real Compiler-incompatibility or a latent re-render bug. +**Next pass: data-fetching pattern migration.** Find admin components with `const [data, setData] = useState(null); useEffect(() => { fetch(...).then(setData) }, []);` and replace with `useQuery({ queryKey, queryFn })`. Land sites: every file in `src/components/admin/*` and a handful of dialog flows (smart-archive-dialog, send-document-dialog, etc.) listed in `eslint.config.mjs`. Each is ~10 min of contained refactor; doing 5 a day for a week clears the suite.
