Implements Phase 6.1 of the state management refactoring plan.
Added detailed documentation for all 5 critical sync points in the
state management architecture, making data flow explicit and traceable.
Sync Points Documented:
1. Document → graphStore (useActiveDocument.ts:67-80)
- When: Active document switches
- What: Loads timeline state into editor
- Direction: ConstellationDocument → graphStore
2. graphStore → timeline current state (useActiveDocument.ts:197-214)
- When: Graph changes detected
- What: Updates timeline's current state
- Direction: graphStore → timeline.states[currentStateId]
3. timeline → document (workspaceStore.ts:789-818)
- When: Document save
- What: Serializes timeline to storage
- Direction: timelineStore → document.timeline → localStorage
4. document types → graphStore (workspaceStore.ts:1018-1034)
- When: Type management operations
- What: Syncs types to editor if active
- Direction: document → graphStore (if active)
5. timeline → graphStore (timelineStore.ts:286-311)
- When: Timeline state switch
- What: Loads state's graph into editor
- Direction: timeline.states[targetId] → graphStore
Each sync point includes:
- ✅ Visual separator for easy identification
- ✅ Trigger condition (when it occurs)
- ✅ Data being synchronized (what changes)
- ✅ Source of truth clarification
- ✅ Data flow direction
- ✅ Context and rationale
Benefits:
- Clear understanding of data flow through the system
- Easier onboarding for new developers
- Prevents accidental breaking of sync relationships
- Makes debugging state issues much faster

Removes ~350 lines of legacy code from single-document system.
Changes:
- Delete src/stores/persistence/loader.ts (legacy load functions)
- Delete src/stores/persistence/saver.ts (legacy save functions)
- Delete src/stores/workspace/migration.ts (no migration support needed)
- Create src/stores/workspace/documentUtils.ts (consolidated utilities)
Extracted and consolidated:
- validateDocument() - document structure validation
- getCurrentGraphFromDocument() - extract current graph from timeline
- deserializeGraphState() - convert storage to runtime format
- serializeActors/Relations/Groups() - convert runtime to storage format
- createDocument() - create new document with initial timeline state
Updated imports:
- workspaceStore.ts: use documentUtils instead of loader/saver
- useActiveDocument.ts: use documentUtils.getCurrentGraphFromDocument
- fileIO.ts: use documentUtils for serialization/validation
- persistence.ts: use documentUtils.validateDocument
- graphStore.ts: remove legacy loadGraphState, start with empty state
Removed legacy storage keys:
- LEGACY_GRAPH_STATE from workspace/persistence.ts
- hasLegacyData() function (no longer needed)
- References to LEGACY_GRAPH_STATE in cleanupStorage.ts
Impact:
- No breaking changes for existing users (workspace format unchanged)
- Cleaner code organization (all document utils in one place)
- No migration support (old documents will not be loaded)
- Reduced technical debt (~350 lines removed)

Implements comprehensive group minimize/maximize functionality and migrates
to React Flow v12 (@xyflow/react) with improved edge routing.
## Group Minimize/Maximize Features:
- Minimized groups render as compact 220×80px solid rectangles
- Original dimensions preserved in metadata and restored on maximize
- Child actors hidden (not filtered) to prevent React Flow state issues
- Solid color backgrounds (transparency removed for minimized state)
- Internal edges filtered out when group is minimized
- Dimension sync before minimize ensures correct size on maximize
## Floating Edges:
- Dynamic edge routing for connections to/from minimized groups
- Edges connect to closest point on minimized group border
- Regular actors maintain fixed handle connections
- Smooth transitions when toggling group state
## React Flow v12 Migration:
- Updated package from 'reactflow' to '@xyflow/react'
- Changed imports to named imports (ReactFlow is now named)
- Updated CSS imports to '@xyflow/react/dist/style.css'
- Fixed NodeProps/EdgeProps to use full Node/Edge types
- Added Record<string, unknown> to data interfaces for v12 compatibility
- Replaced useStore(state => state.connectionNodeId) with useConnection()
- Updated nodeInternals to nodeLookup (renamed in v12)
- Fixed event handler types for v12 API changes
## Edge Label Improvements:
- Added explicit z-index (1000) to edge labels via EdgeLabelRenderer
- Labels now properly render above edge paths
## Type Safety & Code Quality:
- Removed all 'any' type assertions in useDocumentHistory
- Fixed missing React Hook dependencies
- Fixed unused variable warnings
- All ESLint checks passing (0 errors, 0 warnings)
- TypeScript compilation clean
## Bug Fixes:
- Group drag positions now properly persisted to store
- Minimized group styling (removed dotted border, padding)
- Node visibility using 'hidden' property instead of array filtering
- Dimension sync prevents actors from disappearing on maximize

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

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.

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

Fixes an issue where nodes from a previous document would persist when
creating a new document after closing all documents.
The problem occurred because:
1. When all documents were closed (activeDocumentId becomes null), the
graph store wasn't being cleared
2. When a new document was created, stale data from the old document
could contaminate the new document through race conditions
Changes:
- Clear nodes and edges from graph store when activeDocumentId is null
- Add safeguard to prevent saving stale graph data to newly created
documents before they've been fully loaded
- Maintain proper state tracking to prevent cross-document contamination

Added lastSyncedStateRef to track the graph state that was last loaded/synced
for each document. This prevents stale comparisons when switching between
documents by ensuring dirty checks only run against the correct document's
state.
Changes:
- Track last synced state (nodes, edges, nodeTypes, edgeTypes) per document
- Skip dirty check if graph state belongs to a different document
- Compare current graph state against last synced state instead of active document
- Update last synced state reference when loading or saving changes
