System Architecture

Multi-Tenant Structure

Newsletter (slug: "accounting")
  → publication_id (UUID)
    → Campaigns (daily)
      → RSS Posts (scored, assigned)
        → Articles (generated from posts)
          → Email (sent via MailerLite)

CRITICAL: ALL database queries MUST filter by publication_id

Issue Status Lifecycle

draft → processing → ready → approved → sent
         ↓ (if error)
       failed

Status Meanings:

• draft: Issue created, ready for workflow
• processing: Workflow actively running
• ready: Content generated, ready for review
• approved: Manual approval for sending
• sent: Published to subscribers
• failed: Workflow error occurred

Note: "Issue" replaced "campaign" in the codebase. The issues table was formerly newsletter_campaigns.

Core Workflow: 10-Step RSS Processing

Location: src/lib/workflows/process-rss-workflow.ts Architecture: Vercel Workflows Timeout: 800 seconds per step Trigger: /api/cron/trigger-workflow (every 5 minutes)

Workflow Steps

1. Setup (800s)

   • Create tomorrow's campaign
   • Select AI apps/prompts
   • Assign top 24 posts (12 primary + 12 secondary)
   • Run deduplication

2. Generate Primary Titles (800s)

   • Generate 6 primary headlines

3-4. Generate Primary Bodies (800s each)

• Batch 1: Generate 3 primary articles
• Batch 2: Generate 3 more primary articles

5. Fact-Check Primary (800s)

   • Fact-check all 6 primary articles
   • Store fact_check_score (0-10)

6. Generate Secondary Titles (800s)

   • Generate 6 secondary headlines

7-8. Generate Secondary Bodies (800s each)

• Batch 1: Generate 3 secondary articles
• Batch 2: Generate 3 more secondary articles

9. Fact-Check Secondary (800s)

   • Fact-check all 6 secondary articles

10. Finalize (800s)

    • Auto-select top 3 per section
    • Generate welcome section
    • Generate subject line
    • Set status to draft
    • Unassign unused posts

Workflow Best Practices

✅ Error Handling Pattern:

let retryCount = 0
const maxRetries = 2

while (retryCount <= maxRetries) {
  try {
    await processStep()
    return  // Success
  } catch (error) {
    retryCount++
    if (retryCount > maxRetries) {
      console.error('[Step X/10] Failed after retries')
      throw error
    }
    console.log(`[Step X/10] Retrying (${retryCount}/${maxRetries})...`)
    await new Promise(resolve => setTimeout(resolve, 2000))
  }
}

✅ Logging Pattern:

// One-line summaries with prefixes
console.log('[Workflow] Step 1/10: Setup complete, 24 posts assigned')
console.log('[AI] Batch 1/4: Scored 3 posts, avg: 7.2')
console.error('[DB] Query failed:', error.message)

Log Prefixes:

• [Workflow] - Vercel Workflow orchestration
• [RSS] - RSS processing
• [AI] - OpenAI/Claude API calls
• [DB] - Database operations
• [CRON] - Cron job execution

Critical Rules

1. Multi-Tenant Isolation

ALWAYS filter by publication_id:

// ✅ CORRECT
const { data } = await supabaseAdmin
  .from('articles')
  .select('*')
  .eq('campaign_id', campaignId)
  .eq('publication_id', newsletterId)  // REQUIRED

// ❌ WRONG - Data leakage!
const { data } = await supabaseAdmin
  .from('articles')
  .select('*')
  .eq('campaign_id', campaignId)

2. Date/Time Handling

NEVER use UTC conversions for date comparisons:

// ✅ CORRECT: Local date comparison
const dateStr = date.split('T')[0]  // "2025-01-07"
const today = new Date().toISOString().split('T')[0]
if (dateStr === today) { /* ... */ }

// ❌ FORBIDDEN: UTC conversion shifts dates
date.toISOString()  // Wrong timezone!
date.toUTCString()  // Breaks comparisons!

Why: UTC conversion shifts dates by timezone. Users expect Central Time.

3. Performance & Limits

Hard Limits (Vercel):

• Workflow step timeout: 800 seconds (13 minutes per step)
• API route timeout: 600 seconds (10 minutes max)
• Log size: 10MB maximum
• Memory: 1024MB default

AI Integration

Standard Pattern: callAIWithPrompt()

Location: src/lib/openai.ts

import { callAIWithPrompt } from '@/lib/openai'

const result = await callAIWithPrompt(
  'ai_prompt_primary_article_title',  // Key in app_settings
  newsletterId,
  {
    title: post.title,
    description: post.description,
    content: post.full_article_text
  }
)
// result = { headline: "Your Generated Title" }

How it works:

1. Loads complete JSON prompt from app_settings table
2. Replaces placeholders (e.g., {{title}}, {{content}})
3. Calls AI API (OpenAI or Claude)
4. Returns parsed JSON response

Prompt Storage Format

INSERT INTO app_settings (key, value, publication_id, ai_provider)
VALUES (
  'ai_prompt_primary_article_title',
  '{
    "model": "gpt-4o",
    "temperature": 0.7,
    "max_output_tokens": 500,
    "response_format": { "type": "json_schema", "json_schema": {...} },
    "messages": [
      {"role": "system", "content": "You are a headline writer..."},
      {"role": "user", "content": "Title: {{title}}\n\nWrite a headline."}
    ]
  }',
  'newsletter-uuid',
  'openai'
);

All parameters stored in database, not hardcoded.

Database Schema (Key Tables)

Note: "Issues" replaced "campaigns" in the database. The table issues was formerly newsletter_campaigns.

publications (formerly newsletters)
  ├── issues (status: draft → processing → ready → sent)
  │   ├── issue_articles (primary section, 6 generated, 3 active)
  │   ├── secondary_articles (secondary section, 6 generated, 3 active)
  │   └── rss_posts (assigned posts)
  │       └── post_ratings (multi-criteria scores)
  │
  ├── rss_feeds (active/inactive, section assignment)
  ├── publication_settings (key-value config, scoped by publication_id)
  ├── advertisements (advertorials for rotation)
  ├── issue_advertisements (tracks ad usage per issue)
  └── archived_articles, archived_rss_posts (historical data)

---

API Route Template

// app/api/[feature]/route.ts
import { NextRequest, NextResponse } from 'next/server'
import { supabaseAdmin } from '@/lib/supabase'

export async function POST(request: NextRequest) {
  try {
    const body = await request.json()

    if (!body.campaignId) {
      return NextResponse.json(
        { error: 'Missing campaignId' },
        { status: 400 }
      )
    }

    const result = await processData(body)
    return NextResponse.json({ data: result })

  } catch (error: any) {
    console.error('[API] Error:', error.message)
    return NextResponse.json(
      { error: 'Internal server error' },
      { status: 500 }
    )
  }
}

export const maxDuration = 600  // 10 minutes for long operations

Common Tasks

Create New Campaign

const { data: campaign } = await supabaseAdmin
  .from('newsletter_campaigns')
  .insert({
    publication_id: newsletterId,
    date: tomorrowDate,  // YYYY-MM-DD format
    status: 'draft',
    subject_line: null
  })
  .select()
  .single()

Assign RSS Posts to Campaign

await supabaseAdmin
  .from('rss_posts')
  .update({
    campaign_id: campaignId,
    assigned_at: new Date().toISOString(),
    section: 'primary'  // or 'secondary'
  })
  .in('id', topPostIds)
  .eq('publication_id', newsletterId)  // REQUIRED

Generate Article Content

const result = await callAIWithPrompt(
  'ai_prompt_primary_article_body',
  newsletterId,
  {
    title: post.title,
    description: post.description,
    content: post.full_article_text
  }
)

await supabaseAdmin
  .from('articles')
  .insert({
    campaign_id: campaignId,
    publication_id: newsletterId,  // REQUIRED
    rss_post_id: post.id,
    headline: result.headline,
    article_text: result.body,
    fact_check_score: null,
    is_active: false
  })

Troubleshooting

Campaign Stuck in "processing"

-- Check workflow status
SELECT id, status, date, created_at, updated_at
FROM newsletter_campaigns
WHERE status = 'processing'
AND publication_id = 'your-newsletter-id'
ORDER BY created_at DESC;

-- Reset to draft (if needed)
UPDATE newsletter_campaigns
SET status = 'draft'
WHERE id = 'campaign-id'
AND publication_id = 'your-newsletter-id';

Posts Not Scoring

1. Check RSS ingestion: /api/cron/ingest-rss logs
2. Verify criteria config: SELECT * FROM app_settings WHERE key LIKE 'criteria_%' AND publication_id = ?
3. Check prompts exist: SELECT * FROM app_settings WHERE key LIKE 'ai_prompt_criteria_%' AND publication_id = ?
4. Verify feeds active: SELECT * FROM rss_feeds WHERE active = true AND publication_id = ?

Workflow Failures

1. Check Vercel logs: vercel logs --since 1h
2. Check workflow monitor cron: /api/cron/monitor-workflows
3. Look for timeout errors (step > 800s)
4. Check retry count in logs
