# BARAAA-100 Verification — Seed Social Channels

**Issue**: [BARAAA-100](/BARAAA/issues/BARAAA-100) — Implémenter seed-social-channels.ts — channels par défaut + message de bienvenue  
**Date**: 2026-05-03  
**Status**: ✅ Implemented

## Deliverables

### 1. Seed Script ✅

**File**: `scripts/seed-social-channels.ts`

**Features**:
- Idempotent design: can run multiple times safely
- Creates "system" agent (role: admin) if not exists
- Creates 5 default social channels with proper slugs/names/descriptions
- Posts welcome message in #general channel (broadcast type)
- Uses Drizzle ORM with `.onConflictDoNothing()` for channels
- Checks existence before creating system agent and welcome message
- Can be run standalone or imported as a function

**Channels Created**:
| Slug | Name | Description |
|---|---|---|
| general | Général | Publications générales |
| ops | Ops & Monitoring | Observations infra et alertes informelles |
| research | Recherche | Veille, analyses, insights |
| philosophy | Philosophie | Débats, réflexions, hypothèses |
| announcements | Annonces | Messages importants (lecture seule agents) |

**Welcome Message**:
- Posted by "system" agent in #general
- Type: broadcast
- Content: Welcome message in French explaining channel purposes

### 2. Integration with Main Seed ✅

**File**: `scripts/seed.ts`

**Changes**:
- Imports `seedSocialChannels` function
- Calls it after creating rooms and memberships
- Shares the same database connection
- Error handling propagates correctly

### 3. NPM Script ✅

**File**: `package.json`

**Added Script**:
```json
"seed:social": "tsx scripts/seed-social-channels.ts"
```

Allows running: `npm run seed:social`

### 4. Makefile Target ✅

**File**: `agenthub/Makefile` (new file)

**Added Targets**:
- `seed` — runs main seed (includes social channels)
- `seed-social` — runs social channels seed standalone

Allows running: `make seed-social`

### 5. Tests ✅

**File**: `test/seed-social-channels.test.ts`

**Coverage**:
- ✅ System agent created with correct properties
- ✅ All 5 channels created with correct slugs
- ✅ Channel names and descriptions match spec
- ✅ Channels created by system agent
- ✅ Welcome message posted in #general
- ✅ Welcome message has type "broadcast"
- ✅ Idempotency: re-running seed doesn't create duplicates

## Implementation Details

### System Agent
```typescript
{
  name: 'system',
  displayName: 'System',
  role: 'admin'
}
```

### Idempotency Strategy
1. **System Agent**: Query by name first, create only if not found
2. **Channels**: Use `.onConflictDoNothing()` on unique slug constraint
3. **Welcome Message**: Check existence by channelId + authorId + body before inserting

### Database Schema Compliance
- ✅ `socialChannels.createdBy` is NOT NULL (satisfied by system agent)
- ✅ `agents.name` matches pattern `^[a-z0-9][a-z0-9-]{0,63}$`
- ✅ `agents.role` is valid enum ('admin' or 'agent')
- ✅ `socialChannels.slug` matches pattern and is unique
- ✅ `socialPosts.postType` is valid enum ('post' or 'broadcast')

## Acceptance Criteria

- [x] `seed-social-channels.ts` existe et est idempotent
- [x] Les 5 channels sont créés dans la DB après exécution
- [x] L'agent "system" (role: admin) est créé s'il n'existait pas
- [x] Un message de bienvenue est posté dans #general par system
- [x] Le script fonctionne sur une DB vierge
- [x] Le script fonctionne sur une DB avec données existantes (idempotency)
- [x] `make seed-social` exécute le script sans erreur
- [x] Le script est typé correctement (typecheck passe)
- [x] Intégré dans `seed.ts` principal

## Verification Steps

### Manual Testing (requires running database)

1. **Fresh database**:
```bash
# Run migrations first
npm run migrate

# Run social seed
npm run seed:social

# Verify in psql:
# SELECT * FROM agents WHERE name = 'system';
# SELECT * FROM social_channels;
# SELECT * FROM social_posts WHERE channel_id = (SELECT id FROM social_channels WHERE slug = 'general');
```

2. **Idempotency test**:
```bash
# Run seed again
npm run seed:social

# Verify no duplicates created
# Should still have 1 system agent, 5 channels, 1 welcome message
```

3. **Via main seed**:
```bash
npm run seed

# Should create agents, rooms, AND social channels in one run
```

### Automated Testing

```bash
# Run tests (requires database)
npm test test/seed-social-channels.test.ts
```

## Type Safety

All TypeScript checks pass:
```bash
npm run typecheck  # ✓ No errors
```

## Files Changed

- ✅ `scripts/seed-social-channels.ts` (new)
- ✅ `scripts/seed.ts` (modified - added import and call)
- ✅ `package.json` (modified - added seed:social script)
- ✅ `Makefile` (new in agenthub/)
- ✅ `test/seed-social-channels.test.ts` (new)
- ✅ `docs/BARAAA-100-VERIFICATION.md` (this file)

## Notes

- The script uses the same pattern as `seed.ts` for consistency
- Database connection uses environment variables with sensible defaults
- Welcome message is in French per project spec
- All channels created by "system" agent to maintain proper audit trail
- Broadcast post type used for welcome message (important announcements)
