# Post Composition Redesign — Implementation Plan

> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Transform Posts from flat entities into composition orchestrators that assemble Caption + Copy (Translations) + Designs (Artefacts) + Video into a publishable unit with auto-computed readiness.

**Architecture:** Add `caption` and `stage` fields to Posts table. New `/api/posts/:id/composition` endpoint aggregates linked Translations + Artefacts with approval statuses. PostDetailPanel is rewritten as a composition workspace (single scroll, no tabs). Platform→format mapping is a client-side constant.

**Tech Stack:** Express.js, NocoDB, React, Tailwind CSS

**Spec:** `docs/superpowers/specs/2026-03-15-post-composition-redesign.md`

---

## File Structure

**Server:**
- Modify: `server/server.js` — add `caption`/`stage` to Posts TEXT_COLUMNS, new composition endpoint, update POST/PATCH handlers
- Create: `server/post-composition.js` — helper to compute composition, readiness, and stage auto-advance

**Client — New:**
- Create: `client/src/components/PostCompositionPanel.jsx` — the new composition workspace (replaces PostDetailPanel usage)
- Create: `client/src/components/PostCompositionCaption.jsx` — caption section
- Create: `client/src/components/PostCompositionCopy.jsx` — linked translations section
- Create: `client/src/components/PostCompositionDesigns.jsx` — linked design artefacts section
- Create: `client/src/components/PostCompositionVideo.jsx` — linked video artefact section
- Create: `client/src/components/PostCompositionFormats.jsx` — platform format checklist
- Create: `client/src/components/PostCompositionReadiness.jsx` — readiness summary + sign-off
- Create: `client/src/utils/platformFormats.js` — PLATFORM_FORMATS constant

**Client — Modify:**
- Modify: `client/src/pages/PostProduction.jsx` — use PostCompositionPanel instead of PostDetailPanel
- Modify: `client/src/pages/CampaignDetail.jsx` — same
- Modify: `client/src/i18n/en.json` / `ar.json` — new i18n keys

**Client — Keep (unchanged):**
- `PostDetailVersions.jsx`, `PostDetailPlatforms.jsx`, `PostDetailApproval.jsx`, `PostDetailAttachments.jsx` — kept for backward compat, old PostDetailPanel still importable

## Chunk 1: Server — Schema + Composition Endpoint

### Task 1: Add caption and stage to Posts schema

**Files:**
- Modify: `server/server.js` — TEXT_COLUMNS for Posts (~line 520)

- [ ] **Step 1: Add new columns to TEXT_COLUMNS**

Add to the Posts array in TEXT_COLUMNS:
```javascript
{ name: 'caption', uidt: 'LongText' },
{ name: 'stage', uidt: 'SingleLineText' },
```

- [ ] **Step 2: Update POST /api/posts to accept caption and stage**

In the POST handler, add `caption` and `stage` to the create payload:
```javascript
caption: caption || '',
stage: stage || 'copy',
```

- [ ] **Step 3: Update PATCH /api/posts/:id to accept caption**

Add `caption` to the allowed update fields.

- [ ] **Step 4: Commit**

```bash
git add server/server.js
git commit -m "feat: add caption and stage fields to Posts schema"
```

### Task 2: Create post-composition helper

**Files:**
- Create: `server/post-composition.js`

- [ ] **Step 1: Create the helper module**

```javascript
// server/post-composition.js
const nocodb = require('./nocodb');

// Compute full composition for a post
async function getPostComposition(postId) {
  const post = await nocodb.get('Posts', postId);
  if (!post) return null;

  // Linked translations (copy)
  const allTranslations = await nocodb.list('Translations', {
    where: `(post_id,eq,${postId})`,
    limit: 100,
  });
  const copy = allTranslations.map(t => ({
    id: t.Id,
    language: t.language,
    status: t.status || 'draft',
    is_original: t.is_original,
    title: t.title,
  }));

  // Linked artefacts (designs + video)
  const allArtefacts = await nocodb.list('Artefacts', {
    where: `(post_id,eq,${postId})`,
    limit: 100,
  });
  const designs = allArtefacts
    .filter(a => (a.type || 'design') === 'design')
    .map(a => ({
      id: a.Id,
      title: a.title,
      status: a.status || 'draft',
      thumbnail_url: a.thumbnail_url || null,
    }));
  const videoArtefact = allArtefacts.find(a => a.type === 'video');
  const video = videoArtefact ? {
    id: videoArtefact.Id,
    title: videoArtefact.title,
    status: videoArtefact.status || 'draft',
    thumbnail_url: videoArtefact.thumbnail_url || null,
  } : null;

  // Platforms and formats
  let platforms = [];
  try { platforms = JSON.parse(post.platforms || '[]'); } catch { platforms = post.platform ? [post.platform] : []; }

  // Readiness
  const waitingOn = [];
  const copyNotApproved = copy.filter(c => c.status !== 'approved');
  if (copyNotApproved.length > 0) waitingOn.push(...copyNotApproved.map(c => `Copy (${c.language})`));
  const designsNotApproved = designs.filter(d => d.status !== 'approved');
  if (designsNotApproved.length > 0) waitingOn.push(...designsNotApproved.map(d => `Design: ${d.title}`));
  if (video && video.status !== 'approved') waitingOn.push('Video');

  const piecesReady = copy.length > 0 && waitingOn.length === 0;

  return {
    caption: post.caption || '',
    copy,
    designs,
    video,
    platforms,
    pieces_ready: piecesReady,
    waiting_on: waitingOn,
  };
}

// Auto-compute stage from linked pieces
function computeStage(composition) {
  const { copy, designs, video, pieces_ready } = composition;
  if (pieces_ready) return 'post';
  if (designs.length > 0 || video) return 'design';
  if (copy.length > 1 || copy.some(c => !c.is_original)) return 'translate';
  return 'copy';
}

module.exports = { getPostComposition, computeStage };
```

- [ ] **Step 2: Commit**

```bash
git add server/post-composition.js
git commit -m "feat: add post composition helper (readiness, stage auto-compute)"
```

### Task 3: Add composition API endpoint

**Files:**
- Modify: `server/server.js` — add GET /api/posts/:id/composition

- [ ] **Step 1: Add the endpoint**

After the existing GET /api/posts/:id route, add:
```javascript
app.get('/api/posts/:id/composition', requireAuth, async (req, res) => {
  try {
    const { getPostComposition } = require('./post-composition');
    const composition = await getPostComposition(req.params.id);
    if (!composition) return res.status(404).json({ error: 'Post not found' });
    res.json(composition);
  } catch (err) {
    console.error('Composition error:', err);
    res.status(500).json({ error: 'Failed to load composition' });
  }
});
```

- [ ] **Step 2: Auto-update stage on PATCH /api/posts/:id**

In the existing PATCH handler, after saving, re-compute and update stage:
```javascript
const { getPostComposition, computeStage } = require('./post-composition');
const composition = await getPostComposition(req.params.id);
if (composition) {
  const newStage = computeStage(composition);
  await nocodb.update('Posts', Number(req.params.id), { stage: newStage });
}
```

- [ ] **Step 3: Also auto-update post stage when Translation or Artefact status changes**

In PATCH /api/translations/:id and PATCH /api/artefacts/:id — if the record has a `post_id`, re-compute the post's stage after saving.

- [ ] **Step 4: Commit**

```bash
git add server/server.js
git commit -m "feat: add /posts/:id/composition endpoint + stage auto-update"
```

---

## Chunk 2: Client — Platform Formats + Composition Sub-Components

### Task 4: Create platform formats constant

**Files:**
- Create: `client/src/utils/platformFormats.js`

- [ ] **Step 1: Create the file**

```javascript
export const PLATFORM_FORMATS = {
  instagram: [
    { key: 'ig_feed', label: 'Feed (1:1)', ratio: '1:1' },
    { key: 'ig_story', label: 'Story (9:16)', ratio: '9:16' },
    { key: 'ig_reel', label: 'Reel (9:16)', ratio: '9:16' },
  ],
  tiktok: [
    { key: 'tt_video', label: 'TikTok (9:16)', ratio: '9:16' },
  ],
  youtube: [
    { key: 'yt_video', label: 'YouTube (16:9)', ratio: '16:9' },
    { key: 'yt_short', label: 'Short (9:16)', ratio: '9:16' },
    { key: 'yt_thumb', label: 'Thumbnail (16:9)', ratio: '16:9' },
  ],
  facebook: [
    { key: 'fb_post', label: 'Post (1:1)', ratio: '1:1' },
    { key: 'fb_story', label: 'Story (9:16)', ratio: '9:16' },
  ],
  twitter: [
    { key: 'tw_post', label: 'Post (16:9)', ratio: '16:9' },
  ],
  linkedin: [
    { key: 'li_post', label: 'Post (1:1)', ratio: '1:1' },
  ],
  snapchat: [
    { key: 'sc_snap', label: 'Snap (9:16)', ratio: '9:16' },
  ],
}

export function getFormatsForPlatforms(platforms = []) {
  const formats = []
  const seen = new Set()
  for (const p of platforms) {
    for (const f of (PLATFORM_FORMATS[p] || [])) {
      if (!seen.has(f.key)) { seen.add(f.key); formats.push(f) }
    }
  }
  return formats
}
```

- [ ] **Step 2: Commit**

```bash
git add client/src/utils/platformFormats.js
git commit -m "feat: add platform format mapping constant"
```

### Task 5: Create composition sub-components

**Files:**
- Create: `client/src/components/PostCompositionCaption.jsx`
- Create: `client/src/components/PostCompositionCopy.jsx`
- Create: `client/src/components/PostCompositionDesigns.jsx`
- Create: `client/src/components/PostCompositionVideo.jsx`
- Create: `client/src/components/PostCompositionFormats.jsx`
- Create: `client/src/components/PostCompositionReadiness.jsx`

Each is a small focused component (~40-80 lines) rendering one section of the composition workspace.

- [ ] **Step 1: Caption section**

PostCompositionCaption.jsx — textarea for the social media caption. Props: `caption`, `onChange`, `disabled`.

- [ ] **Step 2: Copy section**

PostCompositionCopy.jsx — shows linked translations as language pills with status icons. Props: `copy` (array from composition), `onLink` (opens translation picker), `onCreate` (creates new translation for this post). Each pill is clickable to open the TranslationDetailPanel.

- [ ] **Step 3: Designs section**

PostCompositionDesigns.jsx — shows linked design artefacts as thumbnail cards with status badges. Props: `designs` (array), `onLink`, `onCreate`, `onOpen` (opens ArtefactDetailPanel). Shows "+ Add Design" button.

- [ ] **Step 4: Video section**

PostCompositionVideo.jsx — shows linked video artefact (0 or 1) as a card. Props: `video` (object or null), `onLink`, `onCreate`, `onOpen`.

- [ ] **Step 5: Formats checklist**

PostCompositionFormats.jsx — reads `platforms` from the post, computes needed formats via `getFormatsForPlatforms()`, renders as a checkbox list. This is informational only — checkboxes are manual (designer checks off what they've produced). No database storage for checked state (tracked visually only).

- [ ] **Step 6: Readiness summary**

PostCompositionReadiness.jsx — shows bullet list of what's ready and what's blocking. Props: `piecesReady`, `waitingOn` (array of strings), `onSignOff` (callback for approve/schedule button). Sign-off button disabled until `piecesReady` is true.

- [ ] **Step 7: Commit**

```bash
git add client/src/components/PostComposition*.jsx
git commit -m "feat: add composition sub-components (caption, copy, designs, video, formats, readiness)"
```

## Chunk 3: Client — Main Composition Panel + Page Integration

### Task 6: Create PostCompositionPanel

**Files:**
- Create: `client/src/components/PostCompositionPanel.jsx`

- [ ] **Step 1: Build the panel**

This is a SlidePanel-based component (like existing detail panels) but with a composition layout instead of tabs:

```
Header (title input, status, brand, campaign, platforms, assigned_to, close/save/delete)
─────────
Scrollable body:
  PostCompositionCaption
  PostCompositionCopy
  PostCompositionDesigns
  PostCompositionVideo
  PostCompositionFormats
  PostCompositionReadiness
  CommentsSection
```

Key behavior:
- On mount: fetches composition via `GET /api/posts/:id/composition`
- Caption changes are saved with the post (dirty tracking + save button)
- Copy/Design/Video sections have "Link existing" and "Create new" actions
- "Link existing" opens a small picker modal (list of unlinked translations/artefacts)
- "Create new" calls the create API with `post_id` pre-set, then refreshes composition
- Readiness section shows sign-off button (sets post status to `approved`)
- Each section is a collapsible card (use CollapsibleSection component)

- [ ] **Step 2: Add i18n keys**

Add to en.json and ar.json:
- `post.caption`, `post.captionPlaceholder`, `post.copy`, `post.copyInDesign`, `post.designs`, `post.video`, `post.formatChecklist`, `post.formatsNeeded`, `post.readiness`, `post.allPiecesReady`, `post.waitingOn`, `post.signOff`, `post.approveAndSchedule`, `post.linkExisting`, `post.createNew`, `post.addDesign`, `post.addVideo`, `post.linkTranslation`, `post.noCopyLinked`, `post.noDesignsLinked`, `post.noVideoLinked`

- [ ] **Step 3: Commit**

```bash
git add client/src/components/PostCompositionPanel.jsx client/src/i18n/en.json client/src/i18n/ar.json
git commit -m "feat: add PostCompositionPanel — composition workspace"
```

### Task 7: Wire up PostCompositionPanel in pages

**Files:**
- Modify: `client/src/pages/PostProduction.jsx`
- Modify: `client/src/pages/CampaignDetail.jsx`

- [ ] **Step 1: Update PostProduction.jsx**

Replace `PostDetailPanel` import and usage with `PostCompositionPanel`. The panel receives the same props (post, onClose, onSave, onDelete, brands, teamMembers, campaigns) plus the new composition data fetching happens inside the panel.

- [ ] **Step 2: Update CampaignDetail.jsx**

Same — replace PostDetailPanel with PostCompositionPanel for post detail views.

- [ ] **Step 3: Commit**

```bash
git add client/src/pages/PostProduction.jsx client/src/pages/CampaignDetail.jsx
git commit -m "feat: wire PostCompositionPanel into PostProduction and CampaignDetail"
```

### Task 8: Final verification

- [ ] **Step 1: Build check**

```bash
cd client && npx vite build --logLevel error
```

- [ ] **Step 2: Manual test checklist**

1. Open a post → composition panel shows caption, copy, designs, video, formats, readiness
2. Edit caption → save → caption persists
3. Link an existing translation → appears in copy section with status
4. Link an existing artefact → appears in designs section with thumbnail
5. Create new design artefact from panel → auto-linked to post
6. Select platforms → format checklist updates
7. Approve all pieces → readiness shows "All pieces ready"
8. Sign off → post status changes to approved
9. Stage auto-advances as pieces are linked

- [ ] **Step 3: Commit any fixes**
