# 4.4 - Create authorization matrix for REST and Socket.IO

- [x] 4.4 - Create authorization matrix for REST and Socket.IO #taskmaster #priority/high #status/done ⏫ 🆔 tm-4-4 ⛔ tm-2

## Metadata

| Field | Value |
| --- | --- |
| Taskmaster ID | 4.4 |
| Status | done |
| Priority | high |
| Dependencies | 2 |
| Parent | 4 - Define backend security and refactor strategy from latest audit |

## Description

Map every endpoint and realtime event to access level, ownership checks, state preconditions, rate-limit tier, and audit-log requirement.

## Details

Completed. Produced `09 - Audits/Authorization Matrix - REST and Socket.IO.md` and `09 - Audits/Realtime Authorization Spec.md`.

Include public/authenticated/owner/buyer/seller/admin/support/service-role classifications. Socket.IO rooms must be server-derived from authenticated identity, not client-supplied user IDs.

## Verification

No route or socket event remains unmapped; implementation tasks can reference matrix rows directly.
