 ## Phase 17 - First Vertical Slice: Live Pipeline End-to-End
 
-- [ ] 17. Activate the full data pipeline for a set of tracked symbols

+- [-] 17. Activate the full data pipeline for a set of tracked symbols
+- [x] 17.1 Seed initial symbols and configure sources via the dashboard
   - Use the dashboard Companies page to add 5-10 symbols (e.g. AAPL, MSFT, GOOGL, AMZN, TSLA, NVDA, META, JPM, V, UNH)
   - For each company, add sources via the Company Detail → Sources tab: one `market_api` source (Polygon), one `news_api` source, one `filings_api` source
   - Configure source `config` JSON with the correct Polygon endpoint patterns per ticker
   - Verify companies and sources appear in the dashboard and via `curl https://stonks-registry.celestium.life/companies`
   - _Requirements: 1.1, 1.2, 1.3, 2.1_
 
-- [ ] 17.2 Wire the scheduler to enqueue ingestion jobs for active sources
+- [-] 17.2 Wire the scheduler to enqueue ingestion jobs for active sources
   - Verify the scheduler service reads active companies and sources from PostgreSQL
   - Verify it enqueues Redis jobs for each source on its polling interval
   - Check scheduler logs: `kubectl logs -n stonks-oracle deployment/scheduler --tail=50`
