-## Recommended First Vertical Slice
-- [ ] Track 5 to 10 symbols
-- [ ] Ingest one market data API, one news API, and one filings source per symbol group
-- [ ] Persist raw artifacts to MinIO and metadata to PostgreSQL
-- [ ] Extract structured document intelligence through Ollama
-- [ ] Generate 7-day company trend summaries with market context
-- [ ] Produce paper-trade recommendations only
-- [ ] Publish analytical facts for bars, signals, and paper trades into MinIO
-- [ ] Expose a simple dashboard with evidence, trend cards, and prediction-vs-outcome views
+## Phase 17 - First Vertical Slice: Live Pipeline End-to-End
+
+- [ ] 17. Activate the full data pipeline for a set of tracked symbols
+- [ ] 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
+  - 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`
+  - Confirm ingestion queue has items: check Redis keys via `kubectl exec`
+  - Fix any issues with the scheduler → source → Redis queue flow
+  - _Requirements: 3.1, 3.2_
+
+- [ ] 17.3 Validate ingestion workers pull data from Polygon and persist to MinIO/PostgreSQL
+  - Check ingestion worker logs for successful API calls to Polygon
+  - Verify raw market data artifacts land in MinIO `stonks-raw-market` bucket
+  - Verify document metadata rows appear in PostgreSQL `documents` table
+  - Verify `ingestion_runs` table shows completed runs with `items_fetched > 0`
+  - Debug and fix any adapter errors (auth, rate limits, response parsing)
+  - _Requirements: 4.1, 4.2, 4.3_
+
+- [ ] 17.4 Validate parser normalizes documents and extractor produces intelligence
+  - Check parser worker logs for document processing
+  - Verify normalized text appears in MinIO `stonks-normalized` bucket
+  - Verify `parse_quality_score` and `parse_confidence` are set on documents
+  - Check extractor worker logs for Ollama calls
+  - Verify `document_intelligence` rows appear with summaries, sentiments, and impact records
+  - Verify `document_impact_records` link intelligence to companies
+  - Debug any Ollama connection or schema validation issues
+  - _Requirements: 5.1, 5.2, 6.1, 6.2, 6.3_
+
+- [ ] 17.5 Validate aggregation produces trend summaries
+  - Check aggregation worker logs for trend window generation
+  - Verify `trend_windows` table has entries with direction, strength, confidence
+  - Verify `trend_evidence` table links trends to contributing documents
+  - Verify contradiction scores are computed
+  - Check the dashboard Trends page shows trend cards with real data
+  - _Requirements: 7.1, 7.2, 7.3_
+
+- [ ] 17.6 Validate recommendation engine produces paper-trade recommendations
+  - Check recommendation worker logs for recommendation generation
+  - Verify `recommendations` table has entries with action, confidence, thesis
+  - Verify `recommendation_evidence` links recommendations to documents
+  - Verify risk evaluation runs and `risk_evaluations` table has entries
+  - Check the dashboard Recommendations page shows real recommendations
+  - _Requirements: 8.1, 8.2, 8.3_
+
+- [ ] 17.7 Validate lake publisher writes analytical facts to MinIO/Trino
+  - Check lake-publisher worker logs for Parquet writes
+  - Verify MinIO `stonks-lakehouse` bucket has partitioned Parquet files
+  - Verify Trino can query the lakehouse tables via the SQL Explorer page
+  - Test a sample query: `SELECT * FROM lakehouse.stonks.documents LIMIT 10`
+  - _Requirements: 10.1, 10.2, 10.3_
+
+- [ ] 17.8 Validate dashboard shows live data across all pages
+  - Verify Home page shows non-zero metrics (active companies, documents, recommendations)
+  - Verify Companies page lists seeded companies with source counts
+  - Verify Documents page shows ingested documents with parse quality badges
+  - Verify Trends page shows trend cards with real direction/strength
+  - Verify Recommendations page shows generated recommendations
+  - Verify Ops Pipeline page shows document stage counts
+  - Verify Ops Ingestion page shows throughput data
+  - Take screenshots or curl key endpoints to confirm
+  - _Requirements: 13.1, 13.2, 13.3, 13.4, 13.6_
