- Add NestJS/Prisma/PostgreSQL backend with auth, dashboard stats, reports, templates, users, departments, settings, files, AI, speech, audit logs, and HTML sanitization.

- Add Prisma schema, migrations, seed data, persistent app sessions, Docker/Nginx deployment files, and upload volume configuration.

- Add Vitest, Playwright, backend integration tests, and project documentation for requirements, design, permissions, API contracts, testing, deployment, security, and progress.
