# PR 7 — "Email Team" Modal on Project Detail Page

> **For agentic workers:** Use superpowers:executing-plans for inline execution.

**Goal:** Add an "Email Team" button to `/admin/projects/[id]` that opens a modal composing a custom email to that project's team. Same look + features as `/admin/messages` (subject, body, live HTML preview, send-to-all). Body pre-filled with `Hello [Project Title] team,\n\n` so admin can edit and add their custom content beneath.

**Architecture:** Adds `PROJECT_TEAM` to the existing `RecipientType` enum (5 places) + a resolver branch. New self-contained `<ProjectEmailDialog>` component reuses the existing `message.previewEmail` and `message.send` procedures. No template-system rewrite.

**Spec:** New ask added during PR review (2026-04-28). Not in original spec but adjacent to §B (admin views).

## File map

| File | Action | Why |
|------|--------|-----|
| `src/server/routers/message.ts` | Modify | Add `PROJECT_TEAM` to 4 input enums + 1 resolver case |
| `src/components/admin/project-email-dialog.tsx` | Create | Self-contained modal with subject + body + live preview + send |
| `src/app/(admin)/admin/projects/[id]/page.tsx` | Modify | Add "Email Team" button next to Edit button; render the dialog |
| `tests/unit/message-recipient-project-team.test.ts` | Create | Resolver returns team members + submittedByUserId |

## Tasks

### Task 1: Backend — `PROJECT_TEAM` recipient type

- [ ] **Step 1: Write failing test**

```ts
// tests/unit/message-recipient-project-team.test.ts
import { afterAll, beforeAll, describe, expect, it } from 'vitest'
import { prisma, createCaller } from '../setup'
import {
  createTestUser, createTestProgram, createTestProject, cleanupTestData, uid,
} from '../helpers'
import { messageRouter } from '../../src/server/routers/message'

describe('message.previewRecipients — PROJECT_TEAM', () => {
  let programId: string
  let admin: { id: string; email: string; role: 'SUPER_ADMIN' }
  let projectId: string
  const userIds: string[] = []

  beforeAll(async () => {
    const program = await createTestProgram({ name: `proj-team-${uid()}` })
    programId = program.id

    const lead = await createTestUser('APPLICANT')
    userIds.push(lead.id)
    const project = await createTestProject(programId, { title: 'TestProj' })
    projectId = project.id
    await prisma.project.update({ where: { id: projectId }, data: { submittedByUserId: lead.id } })

    const member1 = await createTestUser('APPLICANT')
    const member2 = await createTestUser('APPLICANT')
    userIds.push(member1.id, member2.id)
    await prisma.teamMember.createMany({
      data: [
        { id: uid('tm'), projectId, userId: member1.id, role: 'MEMBER' },
        { id: uid('tm'), projectId, userId: member2.id, role: 'MEMBER' },
      ],
    })

    const a = await createTestUser('SUPER_ADMIN')
    userIds.push(a.id)
    admin = { id: a.id, email: a.email, role: 'SUPER_ADMIN' }
  })

  afterAll(async () => {
    await cleanupTestData(programId, userIds)
  })

  it('counts the lead + 2 team members', async () => {
    const caller = createCaller(messageRouter, admin)
    const result = await caller.previewRecipients({
      recipientType: 'PROJECT_TEAM',
      recipientFilter: { projectId },
    })
    expect(result.totalApplicants).toBe(3)
  })

  it('returns 0 when projectId is missing', async () => {
    const caller = createCaller(messageRouter, admin)
    const result = await caller.previewRecipients({
      recipientType: 'PROJECT_TEAM',
      recipientFilter: {},
    })
    expect(result.totalApplicants).toBe(0)
  })
})
```

- [ ] **Step 2: Run, expect FAIL** — `'PROJECT_TEAM'` not in enum.

- [ ] **Step 3: Patch `src/server/routers/message.ts`**

Replace ALL FIVE enum literal lines:

```ts
recipientType: z.enum(['USER', 'ROLE', 'ROUND_JURY', 'ROUND_APPLICANTS', 'PROGRAM_TEAM', 'ALL']),
```

with:

```ts
recipientType: z.enum(['USER', 'ROLE', 'ROUND_JURY', 'ROUND_APPLICANTS', 'PROGRAM_TEAM', 'PROJECT_TEAM', 'ALL']),
```

(Use Edit's `replace_all: true` since the line is identical at all 5 occurrences.)

Add a new case in `resolveRecipients` (after `'PROGRAM_TEAM'`):

```ts
    case 'PROJECT_TEAM': {
      const projectId = filter?.projectId as string
      if (!projectId) return []
      const [teamMembers, project] = await Promise.all([
        prisma.teamMember.findMany({
          where: { projectId },
          select: { userId: true },
        }),
        prisma.project.findUnique({
          where: { id: projectId },
          select: { submittedByUserId: true },
        }),
      ])
      const ids = new Set<string>()
      for (const tm of teamMembers) ids.add(tm.userId)
      if (project?.submittedByUserId) ids.add(project.submittedByUserId)
      return [...ids]
    }
```

- [ ] **Step 4: Re-run, expect PASS.**

### Task 2: Build `<ProjectEmailDialog>`

- [ ] **Step 1: Create the component** (full code in execution)

Behaviour:
- Open via `open: boolean; onClose: () => void; projectId: string; projectTitle: string` props.
- On open, body field is pre-filled: ``Hello ${projectTitle} team,\n\n``. Cursor placed at the end.
- Subject field default: empty (admin types).
- Live HTML preview pane below the form, calling `message.previewEmail` with `{ subject, body }` (debounced 300ms).
- Recipient count line: calls `message.previewRecipients` with `PROJECT_TEAM` + `{ projectId }`. Shows "Will email N team members."
- "Send Test" button: sends to the admin only via `message.sendTest`.
- "Send" button: calls `message.send` with `recipientType: 'PROJECT_TEAM'`, `recipientFilter: { projectId }`, `deliveryChannels: ['EMAIL']`, `linkType: 'NONE'`.
- On success: toast + close dialog. On error: toast.

### Task 3: Wire the button on project detail page

- [ ] **Step 1: Add button next to Edit** in `src/app/(admin)/admin/projects/[id]/page.tsx`:

```tsx
<Button variant="outline" onClick={() => setEmailDialogOpen(true)}>
  <Mail className="mr-2 h-4 w-4" />
  Email Team
</Button>
```

(Add `Mail` to the lucide imports. Add `useState` for `emailDialogOpen`.)

Render the dialog at the bottom of the page:

```tsx
{project && (
  <ProjectEmailDialog
    open={emailDialogOpen}
    onClose={() => setEmailDialogOpen(false)}
    projectId={project.id}
    projectTitle={project.title}
  />
)}
```

### Task 4: Verify + commit

- [ ] `npx vitest run tests/unit` → all pass.
- [ ] `npm run typecheck` → clean.
- [ ] `npm run build` → clean.
- [ ] Commit with message referencing PR 7.

## Out of scope

Template picker (admins can use plain body for now; integration with template system can land later). HTML editor (plain textarea — same UX as messages page composer).
