 ## [Unreleased]
+### Fixed
+- Fixed OAuth scopes on six v2 deal sub-resource write operations (`POST /api/v2/deals/{id}/discounts`, `PATCH`/`DELETE /api/v2/deals/{id}/discounts/{discount_id}`, `POST /api/v2/deals/{id}/installments`, `PATCH`/`DELETE /api/v2/deals/{id}/installments/{installment_id}`) that incorrectly listed `deals:read` alongside `deals:full`, copied from their sibling GET operations - these are now `deals:full` only, matching their read-write nature
 
 ## [33.7.0] - 2026-09-08
