TASK-002 Changelog: Legacy Project Migration

---

[2025-07-12] - Backup System Implementation

Summary

Analyzed the v1.1.0 template-project and discovered that projects are already at version "4" (the current supported version). Created the project backup utility for safe migrations.

Key Discovery

Legacy projects from Noodl v1.1.0 are already at project format version "4", which means:

• No version upgrade is needed for the basic project structure
• The existing ProjectPatches/ system handles node-level migrations
• The Upgraders in projectmodel.ts already handle format versions 0→1→2→3→4

Files Created

• packages/noodl-editor/src/editor/src/utils/projectBackup.ts - Backup utility with:
  • createProjectBackup() - Creates timestamped backup before migration
  • listProjectBackups() - Lists all backups for a project
  • restoreProjectBackup() - Restores from a backup
  • getLatestBackup() - Gets most recent backup
  • validateBackup() - Validates backup JSON integrity
  • Automatic cleanup of old backups (default: keeps 5)

Project Format Analysis

project.json structure:
├── name: string            # Project name
├── version: "4"            # Already at current version!
├── components: []          # Array of component definitions
├── settings: {}            # Project settings
├── rootNodeId: string      # Root node reference
├── metadata: {}            # Styles, colors, cloud services
└── variants: []            # UI component variants

Next Steps

• Integrate backup into project loading flow
• Add backup trigger before any project upgrades
• Optionally create CLI tool for batch validation
