+## [1.10.3] - 2026-01-07
+
+### Fixed
+
+- **OIDC config not applied to domains module** - Both `src.auth.oidc` and `src.domains.auth.oidc` configs are now initialized
+  - Previously only `src.auth.oidc` was configured, leaving domains tools using hardcoded "local" user
+  - Environment endpoint now correctly uses authenticated user from OIDC token
+
 ## [1.10.2] - 2026-01-07
