# Check History

`GET /checks/history`

## Request

- Base URL: `https://api.n0brains.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.n0brains.com/checks/history`
- Auth: none declared

The signed-in user's pre-trade check history with resolved outcomes —
powers the /check page's history table. Session JWT or API key. Each row:
the trade as submitted, the grade given, and (once the horizon passes)
the side-adjusted result with stop-touch honored. Rows carry the
engine_version that graded them (additive, 2026-07-31), returned exactly
as STORED — never remapped, never migrated. Grades are only comparable
within one engine generation; historical rows keep their stored grade
exactly (including pre-v3 `B+`). Production's legacy cohort marker is
`v1` (every production row is version-stamped); `null` is reserved for a
genuinely unavailable value and means legacy/unknown. Analytical, not
advice.
