# Frontend: chat views re-fetch full conversation on every new-message socket event

**Severity:** medium
**Domain:** Chat
**Labels:** performance, frontend

## Description

`src/sections/chat/view/buyer-chat-view.tsx:157` calls the full conversation fetch whenever a `new-message` socket event fires. With the chat messages stored as an embedded array (see ISSUE-072), this re-fetches the entire conversation history on every incoming message, causing high network and backend load in active chats.

## Options

1. Append the message from the socket payload to local state; only re-fetch on gaps/errors.
2. Keep re-fetch but debounce it.
3. Hybrid: optimistic append plus periodic reconciliation.

## Recommendation

Append the payload message directly and reconcile only on inconsistency. This changes data-flow correctness assumptions.

## Affected Files

- `frontend/src/sections/chat/view/buyer-chat-view.tsx:157`
- `frontend/src/sections/chat/view/seller-chat-view.tsx` (similar pattern)
