## Summary Completes the workflow persistence overhaul by integrating the new draft system into the app and migrating existing data. Fixes two critical bugs: 1. **QuotaExceededError** - localStorage fills up with workflow drafts, breaking auto-save 2. **Cross-workspace data leakage** - Drafts from one ComfyUI instance appear in another ## Changes - **What**: - `useWorkflowPersistenceV2.ts` - Main composable that hooks into graph changes with 512ms debounce - `migrateV1toV2.ts` - One-time migration of existing drafts to the new scoped format - Updated E2E tests for new storage key patterns - **Why**: Users lose work when storage quota is exceeded, and see confusing workflows from other instances ## How It Works - **Workspace scoping**: Each ComfyUI instance (identified by server URL) has isolated draft storage - **LRU eviction**: When storage is full, oldest drafts are automatically removed (keeps 32 most recent) - **Tab isolation**: Each browser tab tracks its own active/open workflows via sessionStorage - **Debounced saves**: Graph changes are batched with 512ms delay to reduce storage writes ## Migration Existing V1 drafts are automatically migrated on first load. The migration: 1. Reads drafts from old `Comfy.Workflow.*` keys 2. Converts to new workspace-scoped format 3. Cleans up old keys after successful migration --- *Part 4 of 4 in the workflow persistence improvements stack* --------- Co-authored-by: Amp <amp@ampcode.com> Co-authored-by: GitHub Action <action@github.com> Co-authored-by: Simula_r <18093452+simula-r@users.noreply.github.com>
