+### 🐛 Bug Fixes
+
+- **Qwen OAuth Mapping:** Reverted `id_token` reliance to `access_token` and enabled dynamic `resource_url` API endpoint injection for proper regional routing (#900).
+- **Model Sync Engine:** Stored the strict internal Provider ID in `getCustomModels()` sync routines instead of the UI Channel Alias format, preventing SQLite catalog insertion failures (#903).
+- **Claude Code & Codex:** Standardized non-streaming blank responses to Anthropic-formatted `(empty response)` to prevent CLI proxy crashes (#866).
+- **CC Compatible Routing:** Resolved duplicate `/v1` endpoint collision during path concatenation for generic Claude Code gateways (#904).
+- **Antigravity Dashboards:** Blocked unlimited quota models from falsely registering as exhausted `100% Usage` limit states in the Provider Usage UI (#857).
