# Tasks: enterprise-react-campaigns

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

## 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. Write `package.json` at `0.1.0`, `tsconfig.json`, `vitest.config.ts`, scripts.
- [ ] Dependencies: `@suaveplan/error workspace:^`, `@suaveplan/campaigns workspace:^`, `@suaveplan/react-translate workspace:^`, `@suaveplan/react-error-boundary workspace:^`, `@opentelemetry/api catalog:observability`, `zod catalog:forms`, `tslib catalog:build`.

---

## 2. Error codes and types

- [ ] Define `CampaignUiError`; codes: `CAMPAIGN_ENGINE_MISSING`, `CAMPAIGN_UPDATE_FAILED`, `CAMPAIGN_SEND_FAILED`.
- [ ] Define all prop types: `CampaignBuilderProps`, `CampaignListProps`, `CampaignDetailProps`, `CampaignAnalyticsProps`, `CampaignStatusBadgeProps`, `AudienceSelectorProps`, `AudienceGroup`, `UseCampaignOptions`, `UseCampaignReturn`, `UseCampaignListOptions`, `UseCampaignListReturn`, `UseCampaignStatsOptions`, `UseCampaignStatsReturn`.

---

## 3. Provider

### CampaignEngineProvider

- [ ] Provides injected `CampaignEngine` + OTel sink via React context. Throws `CampaignUiError(CAMPAIGN_ENGINE_MISSING)` in dev when hooks called outside provider.
- [ ] `useCampaignEngine()` to consume context.
- [ ] Write test + md.

---

## 4. Hooks

### useCampaign

- [ ] CRUD + lifecycle (send/pause/cancel/duplicate). `update(id, updates)` calls real engine update path. OTel spans: `campaign.created`, `campaign.sent`, `campaign.cancelled`, `campaign.duplicated`. Draft auto-save: debounced 500ms with `localStorage` restore.
- [ ] Write `use-campaign.test.ts` (≤500 lines): CRUD, update calls engine not re-fetch, error propagation, draft auto-save, lifecycle transitions. `{ timeout: 10000 }`.
- [ ] Write `use-campaign.md`.

### useCampaignList

- [ ] Paginated list with filter. OTel `campaign.list.load` span.
- [ ] Write test + md.

### useCampaignStats

- [ ] Loads `CampaignStats` counts; computes open/click/bounce/delivery rates. Optionally subscribes to events stream for realtime delta updates.
- [ ] Write `use-campaign-stats.test.ts` (≤500 lines): rates computed correctly, realtime delta applied. `{ timeout: 10000 }`.
- [ ] Write `use-campaign-stats.md`.

---

## 5. Components

### CampaignStatusBadge

- [ ] Styled status chip for campaign lifecycle states. All labels via `useTranslation`.
- [ ] Write test, stories (all-states, playground), md.

### AudienceSelector

- [ ] Group-based targeting selector with estimated recipient count via `useAudienceCount`. All labels via `useTranslation`.
- [ ] Write test, stories (default, with-groups, empty, playground), md.

### CampaignAnalytics

- [ ] Rates dashboard (open/click/bounce/delivery). `aria-live` region on refresh. All labels via `useTranslation`.
- [ ] Write test, stories (default, zero-sends, high-engagement, playground), md.

### CampaignList

- [ ] Filterable paginated list with `CampaignStatusBadge`. Bulk select + bulk actions (pause/cancel/duplicate).
- [ ] Write test, stories (default, filtered, bulk-select, empty, playground), md.

### CampaignDetail

- [ ] Full campaign view with stats, audience, schedule, template preview.
- [ ] Write `campaign-detail.test.tsx` (≤500 lines): renders all sections, edit triggers useCampaign.update. `{ timeout: 5000 }`.
- [ ] Write stories (default, sending, completed, playground), md.

### CampaignBuilder (+ steps)

- [ ] Top-level wizard ≤250 lines. Step subcomponents in `steps/`: `basics.tsx`, `audience.tsx`, `template.tsx`, `schedule.tsx`, `review.tsx`. Keyboard step navigation, focus trap per step, ARIA progress indicator.
- [ ] Write `campaign-builder.test.tsx` (≤500 lines): renders each step, next/back navigation, Zod validation prevents advance on invalid data, review step shows summary, submit calls useCampaign.create. `{ timeout: 10000 }`.
- [ ] Write stories (default, step-2, step-5-review, validation-errors, playground), md.

### CampaignsErrorBoundary

- [ ] Wrapper via `@suaveplan/react-error-boundary`; displays localised error message + retry button.
- [ ] Write test + md.

## 6. E2E

- [ ] `e2e/campaigns.spec.ts` — Playwright:
  - Complete wizard happy path (fill all 5 steps, submit); verify campaign appears in list.
  - Filter campaign list; verify pagination.
  - Navigate wizard using keyboard only (Tab/Enter/Shift+Tab).
  - Verify mobile viewport renders single-column layout.

---

## 7. Verify and publish

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