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- `.claude/skills/use-static-effect-event/` — skill is obsolete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
- Adds a reusable `<LegalDocVersions />` component (dropdown below the
page header) that swaps the active legal doc version inline via shallow
query-param routing (`?version=v1`).
- Converts `/terms` and `/enterprise-terms` from MDX to TSX pages and
moves their content into versioned MDX under
`apps/www/data/legal/<doc>/v1.mdx`.
- Seeds `v2.mdx` for both docs as a copy of v1 with the effective date
bumped to 6 May 2026 — the actual v2 language edits from legal will land
in a follow-up commit.
## Behavior
- `/terms` and `/enterprise-terms` default to v2 (latest); search
engines and bare URLs always see the latest.
- `/terms?version=v1` (and equivalent for enterprise) renders v1.
- Selecting a version updates the URL via `router.replace({ shallow:
true })` — no full page reload, browser back/forward works.
- Selecting the latest version clears the `version` query param.
- Existing `/docs/company/terms → /terms` redirect still works.
`noindex/nofollow` preserved on `/enterprise-terms` (both via meta and
the existing header rule).
## Out of scope
- The 5 v2 provision edits per agreement (lands in a follow-up once
Legal hands over the final language).
- `/privacy` and other legal pages — those keep their current pattern.
Linear:
[FE-3121](https://linear.app/supabase/issue/FE-3121/update-legal-terms-pages-and-add-version-selector)
## Test plan
- [ ] Visit `/terms` — defaults to v2, dropdown shows "Version 2 — May
6, 2026" and "Version 1 — July 11, 2025"
- [ ] Visit `/terms?version=v1` — renders v1
- [ ] Select v1 from the dropdown — URL becomes `?version=v1`, content
swaps without full page reload (no document request in Network tab)
- [ ] Select v2 — URL drops the `version` param, latest renders
- [ ] Browser back/forward steps through prior selections
- [ ] Repeat the above on `/enterprise-terms`
- [ ] Confirm `/enterprise-terms` is still `noindex, nofollow`
