# TASK-000J Changelog

## Overview

This changelog tracks the implementation of the Canvas Organization System, including Smart Frames, Canvas Navigation, Vertical Snap + Push, and Connection Labels.

### Implementation Phases

1. **Phase 1**: Smart Frames
2. **Phase 2**: Canvas Navigation
3. **Phase 3**: Vertical Snap + Push
4. **Phase 4**: Connection Labels

## [Date TBD] - Task Created

### Summary

Task documentation created for Canvas Organization System.

### Files Created

- `dev-docs/tasks/phase-3/TASK-000J-canvas-organization/README.md` - Full task specification
- `dev-docs/tasks/phase-3/TASK-000J-canvas-organization/CHECKLIST.md` - Implementation checklist
- `dev-docs/tasks/phase-3/TASK-000J-canvas-organization/CHANGELOG.md` - This file
- `dev-docs/tasks/phase-3/TASK-000J-canvas-organization/NOTES.md` - Working notes

### Context

This task was created to address canvas organization challenges in complex node graphs. The primary issues being solved:

1. Vertical node expansion breaking carefully arranged layouts
2. No persistent groupings for related nodes
3. Difficulty navigating large canvases
4. Undocumented connection data flow

The design prioritizes backward compatibility with existing projects and opt-in complexity.

## Blockers Log

_Track any blockers encountered during implementation_

| Date | Blocker | Resolution | Time Lost |
|------|---------|------------|-----------|
| - | - | - | - |

---

## Performance Notes

_Track any performance observations_

| Scenario | Observation | Action Taken |
|----------|-------------|--------------|
| Many nodes in Smart Frame | - | - |
| Minimap with 10+ frames | - | - |
| Long attachment chains | - | - |
| Many connection labels | - | - |

---

## Design Decisions Log

_Record important design decisions and their rationale_

| Date | Decision | Rationale | Alternatives Considered |
|------|----------|-----------|-------------------------|
| - | Smart Frames extend Comments | Backward compatibility; existing infrastructure | New model from scratch |
| - | Opt-in containment (drag in/out) | No forced migration; user controls | Auto-detect based on position |
| - | Vertical-only attachment | Horizontal would interfere with connections | Full 2D magnetic grid |
| - | Label on hover icon | Consistent with existing delete icon | Right-click context menu |

---

## Backward Compatibility Notes

_Track any compatibility considerations_

| Legacy Feature | Impact | Migration Path |
|----------------|--------|----------------|
| Comment boxes | None - work unchanged | Optional: drag nodes in to convert |
| Comment colors | Preserved | Smart Frames inherit |
| Comment fill styles | Preserved | Smart Frames inherit |
| Comment text | Preserved | Becomes frame title |

---

## API Changes

_Track any public API changes for future reference_

### CommentsModel

```typescript
// New methods
addNodeToFrame(commentId: string, nodeId: string): void
removeNodeFromFrame(commentId: string, nodeId: string): void
toggleCollapse(commentId: string): void
isSmartFrame(comment: Comment): boolean
getFrameContainingNode(nodeId: string): Comment | null

// Extended interface
interface Comment {
  // ... existing
  containedNodeIds?: string[];
  isCollapsed?: boolean;
  autoResize?: boolean;
}
```

### Connection Model

```typescript
// Extended interface
interface Connection {
  // ... existing
  label?: {
    text: string;
    position: number;
  }
}
```

### AttachmentsModel (New)

```typescript
interface VerticalAttachment {
  topNodeId: string;
  bottomNodeId: string;
  spacing: number;
}

class AttachmentsModel {
  createAttachment(topId: string, bottomId: string, spacing: number): void
  removeAttachment(topId: string, bottomId: string): void
  getAttachedBelow(nodeId: string): string | null
  getAttachedAbove(nodeId: string): string | null
  getAttachmentChain(nodeId: string): string[]
}
```
