- Emit tool_start/tool_end SSE events from dashboard chat backend and parse them in streaming client helpers
- Track in-flight and completed tool calls in useChat/useQuickChat to preserve tool output summaries alongside assistant messages
- Render collapsed tool call preview blocks in ChatView and QuickChatFAB with dedicated tokenized styles for compact output summaries
- Expand frontend and backend test coverage for SSE tool events, hook state transitions, and collapsed preview rendering behavior
- Add a changeset for @gsxdsm/fusion documenting the new tool-call display behavior
- Rename core loader, dashboard server chat/planning routes, and frontend agent IDs/storage keys from kb-agent to fn-agent naming
- Update dashboard hooks and components (agent list, chat view, quick chat) to use the new fn agent key prefixes consistently
- Refresh engine, dashboard, core, and CLI tests/mocks to remove remaining kb-agent route and temp prefix references
- Update storage/gap-analysis docs to reflect fn agent key names and add a @gsxdsm/fusion patch changeset for the rename
- Trigger onError for unexpected AbortError failures in streamChatResponse while ignoring user-initiated closes
- Keep quick chat user messages on send errors, reset streaming state, and reload messages from the server
- Persist partial assistant output (including thinking-only fallbacks) when AI processing fails mid-stream
- Add regression coverage for stream abort handling, quick chat error UX, and partial-response persistence
- Make useChat and useQuickChat sendMessage synchronous and update consumers to call it without awaiting
- Allow ChatView and QuickChatFAB inputs to remain editable while responses stream
- Keep quick chat send disabled during active streaming to prevent concurrent sends
- Add hook and component tests for synchronous sendMessage and non-blocking input behavior
- Remove unnecessary .reverse() calls when setting messages in useChat.
- Keep paginated prepend behavior intact by using backend chronological ordering directly.
- Update useChat tests to provide message fixtures in oldest-first order.
- Add KB agent fallback support in useQuickChat and allow switching sessions by agent plus model override
- Introduce session target key matching so same target reloads messages while different model selections create distinct sessions
- Update QuickChatFAB to lazy-load models, show model override UI, and keep quick chat usable for model-only conversations
- Add and expand hook/component tests to cover model selection flows, KB session creation, and default-model reset behavior
