TDD found that 'DIRECT' (6 chars) does not fit in VARCHAR(4). Three columns need widening: supplier_projects.platform, project_supplier_links.platform, supplier_leads.platform. supplier_manual_sync_queue.platform was already VARCHAR(8). Done in the same migration as CHECK extension — single atomic deploy. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
