# Rerun Training Sample

`POST /training/samples/{sample_id}/rerun`

## Request

- Base URL: `https://api.verdun.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.verdun.ai/training/samples/{sample_id}/rerun`
- Auth: HTTP bearer

Synchronous replay through ii (10-60s). The response is the persisted
rerun row — status 'failed' rows come back 200 with the error inline so
the network prerequisite (api-backend -> ii security group) degrades
visibly, not silently.

## Path parameters

- `sample_id` string, required

## Request body

- CreateTrainingRerunRequest
  - `prompt_profile` 'production' | 'demo', required: Which prompt to replay against: 'production' is the live prompt; 'demo' is the SSM-backed testing-ground prompt (iterable without a redeploy) — the selector makes re-runs a prompt-A/B surface

## Response `200`

  - `requested_by` string, uuid, nullable: Owner who requested the rerun
  - `prompt_profile` string, required: Prompt profile the clip was replayed against
