Trend charts blank: - trend_windows uses upsert (1 row per ticker/window), so charts had at most 1 data point. Added trend_history table (migration 024) that appends every snapshot. New /api/trends/history endpoint serves the time series. Frontend now uses useTrendHistory for charts and useTrends for the latest summary card. Competitor GUIDs: - list_competitors query returned raw company_b_id UUIDs without joining companies table. Added LEFT JOIN with CASE to resolve the other company's ticker and legal_name. Updated Pydantic model to include enriched fields. Frontend fallback changed from truncated UUID to ticker/legal_name/Unknown.
