This repository consolidates three previously separate projects into a single monorepo while preserving full Git history:

• milestone1/ — Movie Explorer (Flask + TMDB/Wikipedia, Cloud Run)
• milestone2/ — Movie Review App (Flask + Auth + Postgres, App Engine)
• milestone3/ — Full‑stack SPA (Flask API + React client)

Structure was created using git subtree so each subdirectory contains its original commit history, authorship, and tags (if any).

Common tasks:

• Backend (Flask): see each subproject's README for setup and env vars.
• Frontend (React): cd milestone3/client && npm install && npm start.

Notes:

• Future updates from the original repos can be pulled via git subtree pull --prefix=<subdir> <remote> <branch>.
• Issues/PRs from the original repositories are not migrated automatically.

CI

• Automated quality gates via GitHub Actions:
  • Python: Ruff + Black (check) + MyPy + pip-audit
  • React: ESLint (Airbnb) + production build
  • Security: CodeQL (Python & JavaScript)
• Triggers: push/PR (path filtered), weekly schedule, and manual dispatch.
• Dependabot keeps pip/npm dependencies up to date with weekly PRs.
