+**Previous session (2026-03-10):** Feature batch: workspace view, graph view, settings tabs, message queue persistence, ToolCallCard direct-API confirm, duplicate detection scoping, push notification fixes.
+
+**Project Workspace (`/workspace/:projectId`):**
+- `frontend/src/views/WorkspaceView.vue` (new): 3-panel layout (tasks / chat / notes) with CSS grid collapse. Panel toggles in ws-header. Conversation persisted to `localStorage` as `workspace_conv_{projectId}`; deleted on unmount only if brand-new and empty. `sendMessage()` passes `projectId` as both `ragProjectId` and `workspaceProjectId`; `think: true` always enabled. SSE watcher auto-loads note on `create_note`/`update_note`, refreshes task panel on `create_task`/`update_task`.
+- `frontend/src/components/WorkspaceTaskPanel.vue` (new): tasks grouped by milestone (No Milestone first), collapsible groups, task detail slide-over with status cycle + milestone `<select>` + read-only markdown body + TaskLogSection + inline-confirm delete.
+- `frontend/src/components/WorkspaceNoteEditor.vue` (new): list view (search, inline tags, inline delete) ↔ editor view (TipTap + TagInput + WordCount + Suggest button + autosave via `useAutoSave`).
+- Entry point: "Open Workspace" button on `ProjectView.vue` page header.
+- Height fix: `workspace-root` uses `height: 100%`; `app-content:has(.workspace-root)` switches to `overflow: hidden`.
+- Backend: `workspace_project_id` accepted in POST body (`routes/chat.py`), threaded to `run_generation` and `build_context()`; injects system prompt with project title so agent passes `project="Title"` (not ID) to tools.
+
+**Graph View (`/graph`):**
+- `frontend/src/views/GraphView.vue` (new): D3 force-directed graph of all notes/tasks. Tag nodes as first-class nodes (string IDs `"tag:name"`); invisible project hub nodes attract project members. Physics panel with sliders: repulsion (110), link distance (80), link strength (0.50), hub pull (0.05), gravity (0.03). `forceX`/`forceY` for gravity (not `forceCenter`). Clicking tag node → `/notes?tags=name`. Note/task node → 340px slide-in peek panel (type badge, tags, rendered body, linked nodes; Escape/✕ closes). `peek-slide` CSS transition.
+- Router: `/graph` route added to `frontend/src/router/index.ts`.
+- Keyboard shortcut: bare `g` navigates to `/graph` (added to `App.vue`).
+
+**Settings page tabs:**
+- `frontend/src/views/SettingsView.vue`: fully rewritten with 6 tabs — General, Account, Notifications, Integrations, Data, Admin. Tab state persisted to `localStorage` key `settings_tab`. Admin tab only shown when `authStore.isAdmin`. Session invalidation button added in Admin tab (`POST /api/auth/invalidate-sessions`).
+
+**Push notification fixes:**
+- `frontend/public/sw.js`: suppresses notification if the relevant chat tab is already focused (`clients.matchAll()` visibility check before `showNotification`). Works over HTTPS only — Firefox shows "not supported" over plain HTTP.
+- `src/fabledassistant/services/push.py`: errors in `_send_sync` promoted to `logger.error` with `exc_info=True`; successful sends logged at `logger.info`.
+- `src/fabledassistant/services/generation_task.py`: tool-only responses (empty `content_so_far`) now synthesise push notification body from tool names (`"Completed: create_note, create_task"`) instead of sending an empty notification.
+
+**Message queue improvements:**
+- `frontend/src/components/DashboardChatInput.vue`: removed `|| store.streaming` from disabled checks — queue works on the dashboard widget.
+- `frontend/src/stores/chat.ts`: queue persisted to `localStorage` key `fa_conv_queue_{convId}`; saved on enqueue/dequeue, restored in `fetchConversation`, removed on conversation delete. `queuedMessages` computed returns full `QueuedMessage[]` for current conv.
+- `frontend/src/views/ChatView.vue` + `WorkspaceView.vue`: queued messages rendered as user-style bubbles (`linear-gradient(135deg, #6366f1, #4f46e5)`, `border-bottom-right-radius: 4px`, 18px radius, opacity 0.45, right-aligned via `.chat-message.role-user { justify-content: flex-end }`). "QUEUED" label in `rgba(255,255,255,0.75)`. Cancel button clears entire queue.
+
+**ToolCallCard confirm/deny — direct API:**
+- `frontend/src/components/ToolCallCard.vue`: confirm/deny buttons moved **inline in the header row** (no separate block). "Create anyway" posts directly to `POST /api/notes` or `POST /api/tasks` (inferred from `toolCall.function`); shows "✓ Created" on success, "Skipped" on deny — no LLM round-trip. Removed `useChatStore` dependency for these actions. `confirmState: 'idle' | 'creating' | 'created' | 'denied'` local ref.
+- `src/fabledassistant/routes/notes.py` + `routes/tasks.py`: POST handlers now accept `project` (name string) and resolve to `project_id` via `get_project_by_title` when `project_id` not supplied directly.
+
+**Duplicate detection fixes:**
+- `src/fabledassistant/services/tools.py`: `create_note` and `create_task` now scope all three duplicate checks (exact title, fuzzy title, semantic similarity) to the same type only — `is_task=True` for `create_task`, `is_task=False` for `create_note`. A note and a task can share the same title without conflict.
+- `src/fabledassistant/services/embeddings.py`: `semantic_search_notes()` gains `is_task: bool | None = None` parameter; filters SQL join to `Note.status.isnot(None)` / `Note.status.is_(None)` when set.
+- Semantic similarity threshold raised 0.87 → 0.90; minimum body length raised 80 → 200 chars. Catches near-identical content (accidentally duplicated notes) while allowing topically-related notes (e.g. enemy design templates) to coexist.
+
+**Abort button:**
+- ■ Stop button in `ChatView.vue` header and `WorkspaceView.vue` input bar; calls `store.cancelGeneration()`.
+
+**CI fix (ruff E741):**
+- `src/fabledassistant/routes/task_logs.py`: renamed ambiguous variable `l` → `log` in list comprehension.
