PR1 Summary: Project Scaffold + DB + Price Loader

Status: Complete
Date: 2025-12-13

What was built

1. Project scaffold

  • pyproject.toml with all dependencies (SQLAlchemy, Alembic, yfinance, pandas, pytest, ruff, black, etc.)
  • src/pote/ layout with config, db, and ingestion modules
  • .gitignore, .env.example, Makefile for dev workflow
  • Docs: README.md + 6 .md files in docs/ covering MVP, architecture, schema, sources, safety/ethics, and dev setup

2. Database models (SQLAlchemy 2.0)

  • Officials: Congress members (name, chamber, party, state, bioguide_id)
  • Securities: stocks/bonds (ticker, name, exchange, sector)
  • Trades: disclosed transactions (official_id, security_id, transaction_date, filing_date, side, value ranges)
  • Prices: daily OHLCV (security_id, date, open/high/low/close/volume)
  • Metrics stubs: metrics_official and metrics_trade (Phase 2)

Includes proper indexes, unique constraints, and relationships.

3. Alembic migrations

  • Initialized Alembic with env.py wired to our config
  • Generated and applied initial migration (66fd166195e8)
  • DB file: pote.db (SQLite for dev)

4. Price loader (PriceLoader)

  • Fetches daily price data from yfinance
  • Idempotent: skips existing dates, resumes from gaps
  • Upsert logic (insert or update on conflict)
  • Handles single ticker or bulk fetches
  • Logging + basic error handling

5. Tests (pytest)

  • tests/conftest.py: fixtures for in-memory DB, sample officials/securities/trades/prices
  • tests/test_models.py: model creation, relationships, unique constraints, queries (7 tests)
  • tests/test_price_loader.py: loader logic, idempotency, upsert, mocking yfinance (8 tests)
  • Result: 15 tests, all passing

6. Tooling

  • Black + ruff configured and run (all code formatted + linted)
  • Makefile with targets: install, test, lint, format, migrate, clean
  • Smoke-test script: scripts/fetch_sample_prices.py (verified live with AAPL/MSFT/TSLA)

What works now

  • You can spin up the DB, run migrations, fetch price data, and query it
  • All core Phase 1 foundations are in place
  • Tests confirm models and ingestion work correctly

Next steps (PR2+)

Per docs/00_mvp.md:

  • PR2: QuiverQuant or FMP client for Congress trades
  • PR3: ETL job to populate officials and trades tables
  • PR4+: Analytics (abnormal returns, clustering, signals)

How to run

make install
source venv/bin/activate

# Run migrations
make migrate

# Fetch sample prices
python scripts/fetch_sample_prices.py

# Run tests
