Implements a comprehensive label system and completely redesigns all
filtering (labels, actor types, relation types) to use intuitive positive
filtering where empty selection shows all items.
Label System Features:
- Create, edit, delete labels with names, colors, and scope (actors/relations/both)
- Inline editing with click-to-edit UI for quick modifications
- Quick-add label forms in config modals
- Autocomplete label selector with inline label creation
- Label badges rendered on nodes and edges (no overflow limits)
- Full undo/redo support for label operations
- Label validation and cleanup when labels are deleted
- Labels stored per-document in workspace system
Filter System Redesign:
- Changed from negative to positive filtering for all filter types
- Empty selection = show all items (intuitive default)
- Selected items = show only those items (positive filter)
- Consistent behavior across actor types, relation types, and labels
- Clear visual feedback with selection counts and helper text
- Auto-zoom viewport adjustment works for all filter types including labels
Label Cleanup & Validation:
- When label deleted, automatically removed from all nodes/edges across all timeline states
- Label references validated during node/edge updates
- Unknown label IDs filtered out to maintain data integrity
UI Improvements:
- All labels rendered without overflow limits (removed +N more indicators)
- Filter checkboxes start unchecked (select to filter, not hide)
- Helper text explains current filter state
- Selection counts displayed in filter section headers

Implements configurable shape variants for actor nodes, allowing visual
differentiation of node types beyond just color.
Features:
- Five shape options: rectangle, circle, rounded rectangle, ellipse, pill
- All shapes use pure CSS (border-radius) for consistent behavior
- Auto-grow with content
- Perfect shadow and selection/highlight effects
- Proper React Flow handle alignment
- Shape selector UI with visual previews
- Migration logic for existing documents (defaults to rectangle)
Shape characteristics:
- Rectangle: Standard, general purpose
- Circle: Round, for people and concepts
- Rounded Rectangle: Soft edges, friendly appearance
- Ellipse: Oval/horizontal, for processes and stages
- Pill: Capsule, compact for tags and labels
Technical approach:
- Uses border-radius for all shapes (no clip-path)
- Ensures boxShadow follows shape contours properly
- Each shape component maintains consistent props interface
- NodeShapeRenderer routes to appropriate shape component

Refactors the type management system to properly follow the
Workspace→Document→Timeline→Graph hierarchy, where nodeTypes and
edgeTypes are owned by the document rather than being independent
state in graphStore.
Changes:
- Add type management actions to workspaceStore (document-level)
- Update workspaceStore.saveDocument to stop copying types from graphStore
- Modify useActiveDocument to only track node/edge changes for dirty state
- Update useGraphWithHistory to route type operations through workspaceStore
- Update useDocumentHistory to read/restore types from document
Architecture:
- Document: Source of truth for types (persistent storage)
- graphStore: Synchronized working memory (optimized for React Flow)
- useActiveDocument: Bridge that syncs document → graphStore
- Type mutations: Always go through workspaceStore, then sync to graphStore
This ensures proper data ownership while maintaining graphStore as a
performance optimization layer for the UI.

Fixed critical bug where importing a document would lose all timeline
states except the current one. Also cleaned up unused legacy persistence
functions.
Changes:
- Import now preserves complete document structure with all timeline states
- Export already worked correctly, serializing all timeline states
- Updated fileIO to return full ConstellationDocument instead of just graph
- Removed unused legacy functions: hasSavedState, getLastSavedTimestamp, clearSavedState
- Removed unused graphStore export/import (replaced by workspace-level system)
- Updated type definitions to reflect removed functions
The import process now correctly:
1. Accepts full ConstellationDocument from imported JSON
2. Preserves all timeline states and relationships
3. Loads complete timeline into timelineStore
4. Maintains document title and metadata

Removes duplicate confirmation dialogs when deleting documents.
Previously, users were asked twice: once by the UI component's custom
dialog and again by window.confirm in the store.
Changes:
- Remove window.confirm from workspaceStore deleteDocument function
- Add useConfirm hook to DocumentTabs component for delete action
- Consistent confirmation UX across DocumentManager and DocumentTabs
Both components now show the same styled confirmation dialog with
proper handling of unsaved changes warnings.

Implements a comprehensive timeline system that enables documents to contain
multiple constellation states with branching timelines. This allows users to
create different versions of their analysis for temporal evolution, alternative
scenarios, or what-if analysis.
Core Features:
- Timeline store managing multiple states per document with branching structure
- Visual timeline panel with React Flow-based state graph visualization
- State management: create, switch, rename, duplicate (parallel/series), delete
- Per-state undo/redo history (max 50 actions per state)
- Context menu for timeline node operations
- Collapsible timeline panel (always visible, moved toolbar to panel header)
Architecture Changes:
- Document structure: removed top-level graph field, states now only in timeline
- Global types: nodeTypes and edgeTypes are now global per document, not per state
- State graphs: only contain nodes and edges, types inherited from document
- Persistence: full timeline serialization/deserialization with all states
- History system: converted from document-level to per-state independent stacks
Timeline Components:
- TimelineView: main timeline visualization with state nodes and edges
- BottomPanel: collapsible container with timeline controls in header
- StateNode: custom node component showing state info and active indicator
- CreateStateDialog: dialog for creating new timeline states
- RenameStateDialog: dialog for renaming existing states
- Context menu: right-click operations (rename, duplicate parallel/series, delete)
Document Management:
- Documents always have timeline (initialized with root state on creation)
- Timeline persisted with document in localStorage
- Export/import includes complete timeline with all states
- Migration support for legacy single-state documents
Store Updates:
- timelineStore: manages timelines, states, and timeline operations
- historyStore: per-state history with independent undo/redo stacks
- workspaceStore: saves/loads timeline data, handles global types
- panelStore: added timeline panel visibility state
- useActiveDocument: syncs timeline state with graph editor
Context Menu Improvements:
- Smart viewport edge detection to prevent overflow
- Click-outside detection for React Flow panes
- Consistent styling across application
Files Added:
- src/types/timeline.ts - Timeline type definitions
- src/stores/timelineStore.ts - Timeline state management
- src/components/Timeline/TimelineView.tsx - Main timeline component
- src/components/Timeline/BottomPanel.tsx - Timeline panel container
- src/components/Timeline/StateNode.tsx - State node visualization
- src/components/Timeline/CreateStateDialog.tsx - State creation dialog
- src/components/Timeline/RenameStateDialog.tsx - State rename dialog
Files Removed:
- src/stores/persistence/middleware.ts - Obsolete persistence middleware
Documentation:
- Added comprehensive timeline feature documentation
- Implementation checklists and quick reference guides
- Temporal analysis concepts and UX guidelines

Implements toast notifications from UX_ANALYSIS.md to provide clear,
non-intrusive feedback for user actions.
Features:
- Toast store with Zustand for global state management
- Four toast variants: success, error, info, warning
- Auto-dismiss after configurable duration (default 4s)
- Max 3 visible toasts with FIFO queue
- Smart positioning that avoids right panel overlap
- Smooth slide-in/fade-out animations
Notifications added for:
- File operations (import/export success/errors)
- Document operations (create/delete/rename/duplicate)
- Workspace operations (import/export)
Toast container dynamically repositions based on right panel state
to ensure toasts never overlap with critical UI elements.
