Module 2 — Geographic Data: PSGC tables (regions/provinces/cities/ barangays) with native geometry(polygon|point, 4326) columns; cascading dropdown endpoints; ST_Contains-based GPS resolution; service-area CRUD with barangay attach/detach; SamplePsgcSeeder + psgc:import command. Module 3 — User Management: 5 role-specific profile tables (driver/ helper/scanner/store_partner with verification_status + rejection reason); profile auto-created on register; admin user CRUD with filters/pagination, suspend/activate, profile approve/reject; self-service /me + /me/profile with role-aware validation that blocks self-approval and resets rejected profiles to pending on resubmit. 69 feature tests passing.
