Angular + Go + PostgreSQL sample with strict per-tenant isolation. - Backend: Go API (basic auth, tenant-scoped repository layer, pgx pool) - Frontend: Angular 22 SPA (search, checkout, bookings, dashboard) - Database: schema, seed data and demo bookings migrations - Tests: 311 across Go (integration), Angular (unit) and Playwright (e2e), plus a generated evidence report with PDF export - Security: whitebox VAPT report under security/ Secrets (.env, tokens, DB credentials) are git-ignored.
