The compiler auto-memoises, which is the point: it infers what the app's 112 `useCallback` and 48 `useMemo` call sites were hand-written for and applies the equivalent itself. It is on repo-wide with no opt-out list — it bails on anything it cannot prove safe, and says so through the lint rules. Verified in the built bundle rather than assumed: 369 `react.memo_cache_sentinel` markers across 35 of the 76 chunks. ONE transform, shared by vite.config.ts and vitest.config.ts through reactPlugin.ts. Not two `react()` calls: if the compiler ran only in the production build, every vitest run would exercise code the user never receives and a compiler-induced change would ship green — the same gate-vs-image split 0.93.2 was released to fix. The plugin is imported rather than named by the usual string, because a string is invisible to knip and, worse, a typo in it is a silent no-op that ships an uncompiled bundle, while a bad import is a tsc error. eslint-plugin-react-hooks 5 -> 7 brings the whole compiler rule set: 283 findings, triaged rather than bulk-suppressed, because the two halves needed different answers. react-hooks/refs (217) is OFF. 153 of those 217 are this app's popover architecture, not its history: 79 are @floating-ui/react's documented `pop.refs.setReference` / `getReferenceProps` callback-ref setters, and 74 more are passing the popover handle down as a prop, which is what components/ui's popover engine is for. Suppressing them would not help the next popover anyone writes. The remaining ~64 are genuine render-phase `ref.current = x` writes and are real, but the rule cannot tell them apart here; they are E27 S2's work. The other 66 go into eslint-suppressions.json as a ratchet — new violations fail the gate, and `--prune-suppressions` makes a fixed one fail too until it is removed. 45 of them are `set-state-in-effect`, which IS E27 S2's subject, so that sprint now has a measured worklist. react-i18next deliberately stays on 14. It never declared a React-19 peer — every version from 14 to 17 asks only for `react >= 16.8.0` — and what the newer lines actually require is i18next 25/26 against our 23. That is an i18n runtime migration wearing a React hat, and it buys this sprint nothing. Two React 19 type changes: `useRef<T>(null)` is now `RefObject<T | null>` (the honest shape — the element is null until it mounts), so PlexPlayerSettings' prop follows; and reactPlugin.ts joins tsconfig.node.json's include. The compiler skips memoising VirtualGrid and reports it: TanStack Virtual's `useVirtualizer()` returns functions that cannot be memoised without going stale. That is the right trade for a component whose cost is its row window, and it is the one such site in the app, so it carries a targeted disable with the reason — a second incompatible library anywhere else must still stop the gate. Nine lanes green, vitest 1558. Browser UAT on the dev server against the still-running React 18 build as a control: boot, feed (virtualized grid, popover menu, a filter change that moved the list 195,187 -> 64 items with the URL mirrored, so no stale memoised UI), command palette, player modal — no console errors on any of it.
