Subject: [PATCH 1/2] Add historical data loader with complete Phase 1 coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implemented comprehensive historical data loader script with 4 phases:

Phase 1: Corporate Actions + Fundamentals + Short Data (Parallel)
- Corporate actions: Dividends, splits, IPOs (2005-2025)
- Ticker events: Symbol changes/rebranding (all history)
- Fundamentals: Balance sheets, income, cash flow (2010-2025)
- Short data: Short interest & volume (2 years)

Phase 2: Daily Price Data (S3, 10 years, parallel)

Phase 3: News Data (3 years, parallel)

Phase 4: Minute Data (Stocks + Options, sequential, 5 years)

Features:
- Aggressive parallelization (8-10 concurrent jobs for API/S3)
- Sequential processing for Phase 4 (memory-safe for 500GB datasets)
- Skip flags: --skip-confirmation, --skip-minute
- Dry-run mode for execution preview
- Phase-specific execution: --phase N
- Progress tracking and monitoring

Removed: scripts/bulk_download_all_data.sh (consolidated into this script)

+# QuantMini Historical Data Load - MAXIMUM PERFORMANCE VERSION
+#
+# Optimized for:
+# - Apple M4 (10 cores: 4 performance + 6 efficiency)
+# - 24GB RAM
+# - 1000 Mbps internet
+# - Unlimited Polygon API tier
+# - 3.6TB external SSD (Samsung 990 EVO PLUS)
+#
+# Performance Strategy:
+# - Phase 1: Parallel API downloads (Corporate Actions + Fundamentals + Short Data)
+#   * Dividends, Splits, IPOs, Ticker Events (2005-2025)
+#   * Balance Sheets, Income, Cash Flow (2010-2025)
+#   * Short Interest & Short Volume (2 years)
+# - Phase 2: Parallel S3 downloads (Daily price data, 10 years)
+# - Phase 3: Parallel news downloads (3 years)
+# - Phase 4: Sequential minute data ingestion (Stocks + Options, year-by-year)
+# - Aggressive parallelization: 8-10 concurrent jobs (Phases 1-3)
+# - Sequential processing for Phase 4 (memory-safe for large datasets)
+# - Real-time monitoring with progress dashboard
+#
+# Usage:
+#   ./scripts/historical_data_load.sh [--phase N] [--skip-confirmation] [--skip-minute]
+#
+# Options:
+#   --phase N              Run specific phase only (1, 2, 3, or 4)
+#   --skip-confirmation    Skip confirmation prompts
+#   --skip-minute          Skip Phase 4 (minute data) - saves ~500 GB and 10-15 hours
+#   --dry-run              Show execution plan without running

Subject: [PATCH 2/2] Move news data to bronze layer and add Phase 3 download
 script

- Update news output path from news/ to bronze/news/ in CLI and scripts
- Add phase3_news_download.py for historical news backfill (10 years)
- Update PROJECT_MEMORY.md with comprehensive bronze layer structure
- Add financial ratios download command to Polygon CLI
- Verify 739K news files (12GB) already in correct bronze location

Data verified:
- 739,424 parquet files (12GB)
- 9,900 active tickers
- 10 years of history (2015-10-25 to 2025-10-22)
- 100% success rate

+## Pipeline Entry Points
+
+**IMPORTANT**: The project has ONLY two entry point scripts for all data operations:
+
+1. **`scripts/daily_update_parallel.sh`** - Daily/incremental updates
+   - Processes recent data (default: yesterday, configurable with `--days-back`)
+   - Runs all layers in parallel for maximum performance
+   - Use for: daily automation, backfilling recent data
+
+2. **`scripts/historical_data_load.sh`** - Historical data downloads
+   - Downloads large historical datasets (multi-year)
+   - Optimized for bulk downloads with aggressive parallelization
+   - Use for: initial setup, downloading historical fundamentals/short data
+
+**All other scripts are internal components** called by these two entry points. Do not run individual scripts directly unless debugging.
