Phase 1: Baseline Capture

1. Google Sheets stores target webpage URLs
2. Apify captures high-quality screenshots of each page
3. Images stored in Google Drive as baseline references

Phase 2: Regression Detection

1. Scheduled trigger initiates testing after site changes
2. Apify generates fresh screenshots of the same pages
3. Both baseline and new images retrieved in parallel
4. Multimodal LLM analyzes visual differences between versions
5. AI identifies and documents specific UI discrepancies
6. Detailed report uploaded to Linear for review and action

The entire process runs autonomously without human intervention, transforming a labor-intensive manual process into a reliable automated workflow.
