# Tasks: enterprise-react-modal

**Change ID**: enterprise-react-modal
**Package**: `@suaveplan/react-modal`
**Target path**: `react/ui/react-modal`
**Prerequisite packages on Verdaccio**: `@suaveplan/error`, `@suaveplan/react-translate`

## 0. Pre-flight (non-negotiable)

- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.

## 1. Scaffold

- [ ] Create directory tree per proposal layout.
- [ ] Write `package.json` at `0.1.0` with `"sideEffects": false`, exports map.
- [ ] Dependencies: `@suaveplan/error workspace:^`, `@suaveplan/react-translate workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `tslib catalog:build`.
- [ ] Write `tsconfig.json`, `vitest.config.ts`, scripts.

---

## 2. Error codes

- [ ] Define `ModalError` extending `SuaveplanError`; code: `MODAL_CONTEXT_MISSING`.

---

## 3. Utilities

- [ ] `src/utils/scroll-lock/` — `disableBodyScroll()` / `enableBodyScroll()` with ref counting (nested modals). Write test (jsdom), md.
- [ ] `src/utils/focus-trap/` — `createFocusTrap(container)` using `querySelectorAll` for focusable elements; `activate()` / `deactivate()`; wraps focus at boundaries. Write test, md.

---

## 4. Components

### Modal

- [ ] Portal via `createPortal` to `document.body` (or custom `portalTarget`).
- [ ] Activates `focus-trap` on open, restores previous focus on close.
- [ ] Calls `disableBodyScroll` on open, `enableBodyScroll` on close.
- [ ] ESC keydown closes if `closeOnEsc` prop (default `true`).
- [ ] Backdrop click closes if `closeOnBackdrop` prop (default `true`).
- [ ] Emits OTel `modal.open` span on open, `modal.close` on close with `modal.id` attribute.
- [ ] Write `modal.test.tsx` (renders, ESC close, backdrop close, focus trap activated, scroll-lock toggled). `{ timeout: 5000 }`.
- [ ] Write `modal.stories.tsx`: default, no-backdrop-close, full-screen, playground.
- [ ] Write `modal.md` (≥200 words).

### Dialog

- [ ] Composed on `Modal` with `title`, `description`, `actions` slots; renders `<dialog>` semantics (`role="dialog"`, `aria-labelledby`, `aria-describedby`).
- [ ] Write test, stories, md.

### ConfirmDialog

- [ ] Composed on `Dialog` with confirm / cancel buttons; uses `useTranslation` for button labels.
- [ ] Write test, stories, md.

### ModalContext + ModalProvider

- [ ] `ModalProvider` maintains a `Map<string, ReactElement>` of open modals; renders each via `Modal`.
- [ ] `useModalContext` throws `ModalError(MODAL_CONTEXT_MISSING)` outside provider.
- [ ] `open(id, element)`, `close(id)`, `closeAll()`, `isOpen(id)`.
- [ ] Write test (open/close/closeAll/isOpen/stacking), stories (stacked-modals, playground), md.

---

## 5. E2E

- [ ] `e2e/modal.spec.ts` — Playwright:
  - Open `Modal`, verify focus inside, Tab cycles within modal, Shift+Tab cycles backward, ESC closes.
  - Open `Modal`, verify `overflow: hidden` on `body`.
  - Open two stacked modals via `ModalProvider`, close inner, verify outer still rendered.

---

## 6. Verify and publish

- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/react-modal` — green.
- [ ] `bunx turbo test:coverage --filter=@suaveplan/react-modal` — 100%.
- [ ] `bun scripts/publish.ts --package @suaveplan/react-modal`.
- [ ] Archive change folder.
