# shared/data/

Holds the backtest cache (SQLite) built by stage 02_fetch_cache.

- `backtest_cache.sqlite3` — keyed by (contract, timespan, window). Cache-first:
  existing rows are never re-pulled from TTG data servers.
- This folder may grow large. Cap discipline lives in `_config/risk-params.md`.
- Delete the .sqlite3 file to force a full re-pull (stage 02 will rebuild it).
