finances-snapshot

Capture current financial state and update prices.

Steps

1. Fetch latest prices:

   cd ~/Documents/finances && uv run python scripts/fetch_prices.py
   

2. If balance sheet CSVs are stale: ask user to export fresh ones from Copilot Money and drop them in ~/Documents/finances/
3. Capture snapshot:

   uv run python scripts/snapshot.py
   

What Gets Updated

• data/prices/btc.jsonl — latest BTC price from CoinGecko
• data/prices/gold.jsonl — gold spot via yfinance (GC=F)
• data/prices/silver.jsonl — silver spot via yfinance (SI=F)
• data/snapshots.jsonl — new net worth entry (assets, liabilities, BTC, breakdown)
• data/liabilities.jsonl — current liability balances with APRs

Idempotent

Running twice on the same day is safe — snapshot.py skips if today already exists.
