# Supervisory Scenario Replay (DFAST-lite)

`POST /v1/tools/replay_supervisory_scenario`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/replay_supervisory_scenario`
- Auth: none declared

Replays the Fed's published 2026 28-variable supervisory scenario paths (baseline and severely adverse, Q1:2026-Q1:2029) against user-supplied loss and PPNR coefficient functions, producing a quarterly P&L and capital walk. This is a replay of user functions over official published inputs, not the Fed's model and not a DFAST submission.

**Tool URL:** https://ainumbers.co/chaingraph/art-370-supervisory-scenario-replay.html
**AP2/Policy Mandate export:** yes
