# Backtest Tweaks

`POST /v1/backtests/{run_id}/tweaks`

## Request

- Base URL: `https://api.quantradin.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.quantradin.com/v1/backtests/{run_id}/tweaks`
- Auth: none declared

Up to four concrete tweaks for a graded run, each with a plain-words why and
a FULL patched spec the member can apply with one click.

AI proposes; NOTHING auto-applies; the engine re-grades on the member's click.
A tweak whose spec does not validate keeps its explanation and loses its Apply
button — we never hand back a spec that cannot run.

Session-cookie only (an account key pair gains no AI access). 404 on a missing
or foreign run — byte-identical either way, so probing another member's ids
tells a stranger nothing.

## Path parameters

- `run_id` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
