# Get Backtest Summary

`GET /api/methodology/backtest-summary`

## Request

- Base URL: `https://api.equity-rank.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.equity-rank.com/api/methodology/backtest-summary`
- Auth: none declared

Return combined signal backtest proof statistics.

No authentication required. Designed for public viewing on /methodology.

Checks Supabase methodology_stats for real data (real_n >= 50); if unavailable
or insufficient, returns the hardcoded proof numbers from the synthetic simulation.

## Response `200`

Successful Response

- AppRoutersMethodologyBacktestSummaryResponse: Response model for GET /api/methodology/backtest-summary. Topline hit-rate fields are permanently null (see _WITHHELD_DATA_SOURCE note above) — kept in the model so existing consumers deserialize cleanly; every consumer must treat null as "withheld", not zero.
