# 🟠 updatePurchaseRequest uses PUT but backend only registers PATCH — all purchase request edits fail

**Severity:** major
**Domain:** Purchase Request
**Labels:** bug, frontend, major, broken-feature

## Description

The frontend updatePurchaseRequest action (marketplace.ts line 71) calls axiosInstance.put against '/marketplace/purchase-requests/:id'. Backend registers PATCH (not PUT) on /purchase-requests/:id. PUT returns 404 from the controller router.

## Current Behavior

Purchase request edits from the buyer edit view fail with 404/405.

## Expected Behavior

updatePurchaseRequest should call axiosInstance.patch().

## Affected Files

- `frontend/src/actions/marketplace.ts`
