Prompt and implementation changelog

Prompt

Create a CMS React application with a Go backend, initialize a Git repository, and prepare the security foundation first. Add an extensible external identity-provider login beginning with Google, a protected test page, and an admin login at /admin/login whose link is never exposed in user-facing pages. Use Goose for migrations and GORM for persistence. Structure the backend into web handlers, web-to-domain mapping, domain-only services, database models, repositories, and domain/database mappers. Prefix interfaces with I. Use Go 1.27.1 and the latest React. Keep this changelog in ui/changelog.md.

Tasks completed

• Initialized a local Git repository on the main branch; GitHub remote configuration is intentionally left for later.
• Added a Go 1.27.1 backend module with configuration via environment variables.
• Added layered backend packages for domain, web handlers and mapping, services, repositories, persistence models, and persistence mapping.
• Added GORM with SQLite as the local database driver and Goose migrations for users, administrators, and sessions.
• Added an OAuth provider abstraction and Google OAuth authorization-code flow with state validation, userinfo lookup, and an HTTP-only session cookie.
• Added health, session, Google auth, protected test, and hidden admin login routes.
• Added a React/Vite frontend with a public Google sign-in page, protected /test page, and /admin/login route without a visible navigation link.
• Added environment examples, ignore rules, README documentation, and backend unit tests.
• Verified Go tests and prepared frontend typecheck/build scripts.
