# 🟠 select-offer does not send per-seller socket events or notifications to winning or losing sellers

**Severity:** major
**Domain:** Seller Offer
**Labels:** bug, backend, major, notifications, socket

## Description

POST /purchase-requests/:id/select-offer route (routes.ts lines 1300-1438) emits only a single purchase-request-update event to the request room. It does NOT call notifyOfferAccepted, does NOT call notifyOfferRejected for losing sellers, and does NOT emit seller-offer-update events. Those notifications only fire via SellerOfferService.updateOfferStatus().

## Current Behavior

After a buyer selects an offer via select-offer, the winning seller receives no notification and losing sellers receive no rejection notification.

## Expected Behavior

The select-offer path should emit per-seller socket events and notifications equivalent to what SellerOfferService.acceptOffer() does — notify the winning seller and each losing seller.
