file.
YES
## What kind of change does this PR introduce?
Chore / build (ESLint config upgrade + lint cleanup).
## What is the current behavior?
`eslint-plugin-react-hooks` v5 (pulled in transitively by
`eslint-config-next` v15) doesn't recognize stable `useEffectEvent`, so
every effect that calls an effect-event handler needs an `eslint-disable
react-hooks/exhaustive-deps` to silence a false positive. There are 30
such dead disables across Studio.
## What is the new behavior?
Bumps `eslint-config-next` to v16, which pulls in
`eslint-plugin-react-hooks` v7 whose `exhaustive-deps` understands
`useEffectEvent`, and removes the 30 now-dead disable directives (and
their orphaned explanatory comments).
Supporting changes:
- **Flat-config migration**: v16 is a native flat-config array (v15 was
eslintrc), so `eslint-config-supabase` now spreads it directly instead
of bridging through `FlatCompat`.
- **React Compiler rules off**: v16 enables react-hooks v7's
`recommended`, which layers the React Compiler lint rules on top of the
two classic rules. These are switched off (derived dynamically from what
next enables) to keep this change scoped to the `exhaustive-deps`
improvement.
- **Plugin-registration fallout** (v16 scopes plugin registration to a
file glob rather than registering globally like FlatCompat did): stop
re-registering `@typescript-eslint` (shared) and `jsx-a11y` (studio);
scope our react / react-hooks / jsx-a11y rule overrides (studio, www) to
v16's plugin glob so they don't error on files outside it (e.g. `.cjs`).
- **Lint surface preserved**: v16's glob newly includes `.mts`/`.cts`
(v15 didn't lint them), which surfaced pre-existing errors in tooling
scripts. The shared config keeps the prior surface by leaving
`.mts`/`.cts` unlinted; linting them is left as a separate change.
- **Ratchet**: rebaselines `@tanstack/query/exhaustive-deps` 9 → 89. v15
forced next's `@babel/eslint-parser` onto `.ts` files, hiding these
deps; v16 parses `.ts` with `@typescript-eslint/parser` and correctly
surfaces the intentional `connectionString`-excluded-from-`queryKey`
pattern. Worth a follow-up to review whether any are real
cache-correctness bugs.
- Drops three now-dead devDeps from `eslint-config-supabase`:
`@eslint/eslintrc`, `@eslint/js`, `@typescript-eslint/eslint-plugin`.
Verified locally: `turbo run lint` → 7/7 packages pass with 0 errors;
Studio `lint:ratchet` passes; Prettier clean on changed files; typecheck
unaffected.

## Summary by CodeRabbit
* **Chores**
* Refined linting configuration and removed outdated lint suppressions
across Studio.
* Updated Next.js linting support and refreshed related development
configuration.
* Expanded lint baseline coverage for query-related code.

Studio is on `react@^19.2.6`, and `useEffectEvent` shipped stable in
React 19.2 with the same signature as the userland polyfill. This drops
the local hook in `apps/studio` and `apps/www` in favor of the built-in.
**Removed:**
- `apps/studio/hooks/useStaticEffectEvent.ts`
- `apps/www/hooks/useStaticEffectEvent.ts`
- `.claude/skills/use-static-effect-event/` — skill is obsolete
**Changed:**
- 26 call sites: dropped the `useStaticEffectEvent` import, added
`useEffectEvent` to the existing `react` import, renamed call sites
- `.claude/CLAUDE.md`: `apps/studio` row updated React 18 → React 19
- `.claude/skills/vercel-composition-patterns/SKILL.md`: removed stale
"Studio uses React 18, skip these patterns" warning
## To test
- `pnpm typecheck --filter=studio` — passes locally
- `pnpm typecheck --filter=www` — passes locally
- `grep -rn "useStaticEffectEvent"` returns nothing outside
`node_modules`
- Smoke-test areas that use the hook: schema visualizer edges
(intersection check), spreadsheet import, sign-in/CLI login flows, side
panels with unsaved-changes prompts
**Out of scope:** pre-existing Tailwind lint warning on
`DefaultEdge.tsx:141` (`outline` + `outline-1` conflict) — unrelated to
this migration

## Summary by CodeRabbit
* **Refactor**
* Internal event handling migrated to React’s built-in event hooks
across the Studio app; no user-facing changes.
* **Documentation**
* Clarified React 19 compatibility and noted Studio now targets React
19.
* Removed obsolete documentation for a deprecated internal hook.

Feature
## What is the current behavior?
Data API settings live under Project Settings.
## What is the new behavior?
Data API settings are moved to the Integrations page, treating Data API
as a platform integration. Includes security checks when toggling on the
Data API to prevent unintended exposure of project data.
## Additional context
Towards FE-2517
## Summary by CodeRabbit
* **New Features**
* Added a Data API integration with Overview and Settings pages,
endpoint display, and enable/disable toggle with safety checks and
confirmation flow.
* **Navigation Changes**
* Data API moved from Project Settings into the Integrations area and
routes now redirect to the new Overview page.
* **Documentation**
* Added an overview doc describing Data API endpoints and configuration.
* **Tests**
* Added unit tests for endpoint resolution and schema parsing utilities.
