+
+## Global Agent Scope Gate Fix (v0.241.007)
+
+Fixed/Implemented in version: **0.241.007**
+
+### Issue Description
+
+Per-user Semantic Kernel chats could silently fall back to the standard GPT model
+when a user selected a global agent from the chat UI. The frontend showed no
+error because the selection API accepted the agent and the streaming request
+included that `agent_info`, but the backend still dropped into model-only mode.
+
+### Root Cause Analysis
+
+The per-user loader treated every non-group agent as a personal agent during the
+scope gate check. When `allow_user_agents` was disabled and
+`merge_global_semantic_kernel_with_workspace` was enabled, selected global agents
+were blocked before the loader reached the global-agent merge and selection path.
+
+### Technical Details
+
+Files modified:
+- `application/single_app/functions_agent_scope.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/config.py`
+- `functional_tests/test_global_agent_scope_gate.py`
+
+Code changes summary:
+- Added `is_selected_agent_scope_enabled()` to centralize scope gating for
+  personal, global, and group agent selections.
+- Updated `load_user_semantic_kernel()` so global agents bypass the
+  `allow_user_agents` toggle while personal and group agent rules remain intact.
+- Added regression coverage for the global-agent bypass, group-agent enforcement,
+  and loader wiring.
+
+Testing approach:
+- Added `functional_tests/test_global_agent_scope_gate.py` to validate the scope
+  helper behavior and confirm the per-user loader uses it.
+
+Impact analysis:
+- Global agents selected in per-user chat mode now remain on the agent invocation
+  path instead of silently reverting to model-only GPT routing.
+- Personal and group scope restrictions continue to behave as configured.
+
+### Validation
+
+Before:
+- The backend logged `Using agent from request` and then immediately logged
+  `User agents are disabled; skipping personal agent load.` for global agents.
+- Requests fell back to `Loading core plugins only for model-only mode...`.
+
+After:
+- Global agent selections are no longer blocked by the personal-agent gate.
+- Group selections still require `allow_group_agents`, and personal selections
+  still require `allow_user_agents`.
+- The regression test protects the shared scope gate and its loader integration.

 ### **(v0.241.007)**
 
-#### New Features
+#### Bug Fixes
 
-*   **Collaborative Conversations Foundation**
-    *   Added the first backend foundation for multi-user collaborative conversations with dedicated conversation, message, and per-user membership state storage in Cosmos DB.
-    *   Added protected APIs for creating personal or group collaborative conversations, accepting invites, inviting or removing members in personal conversations, posting human messages, publishing typing events, and subscribing to a conversation-wide SSE event stream.
-    *   This initial slice keeps the existing single-user chat experience intact while establishing the persistence and eventing layer needed for shared conversation UI, explicit AI invocation, and future read-state improvements.
-    *   (Ref: `collaboration_models.py`, `functions_collaboration.py`, `route_backend_collaboration.py`, `config.py`, `test_collaborative_conversation_foundation.py`)
-
-*   **Core Document Search And Summarization**
-    *   Added a shared backend document search service with a dedicated authenticated API for hybrid search, ordered document-chunk retrieval, and on-demand document summarization.
-    *   Added an always-loaded Semantic Kernel core plugin so every agent and model-only kernel session can search accessible workspace documents, pull full ordered chunk windows for a document, and run hierarchical summarization with optional focus and target-length guidance.
-    *   The new summarization flow can now work across the whole document instead of relying only on distilled top search hits, which improves long-document summarization and creates a reusable foundation for future document comparison workflows.
-    *   (Ref: `functions_search.py`, `functions_search_service.py`, `functions_documents.py`, `route_backend_search.py`, `document_search_plugin.py`, `semantic_kernel_loader.py`)
+*   **Global Agent Scope Gate Fallback**
+    *   Fixed per-user Semantic Kernel chats so selecting a global agent no longer silently falls back to the standard GPT model when personal agents are disabled for the tenant.
+    *   The per-user loader now treats global, personal, and group agent scopes separately, allowing valid global-agent selections to continue through agent invocation while keeping personal and group scope toggles enforced as configured.
+    *   Added regression coverage for the shared scope gate used by the per-user loader.
+    *   (Ref: `semantic_kernel_loader.py`, `functions_agent_scope.py`, `test_global_agent_scope_gate.py`, global agent request routing)
