The engine's technical architecture: bash terminal → batch file (pipe-separated, 6 fields) → Python batch_insert.py (field validation, database insertion) → Python rebuild.py (unique extraction, feed.xml, sitemap.xml, index.html) → git add/commit/push → GitLab CI/CD → Cloudflare Pages deployment. The pipeline has processed 4,030 articles with 3 recoverable errors (all pipe characters in verbatim quotes) and zero permanent failures. Key design decisions that enabled this reliability: (1) pipe-separated format with strict field count validation, (2) idempotent insertion (duplicate IDs are safe), (3) deterministic rebuild (same input → same output), (4) git versioning (every change is traceable), (5) CI/CD automation (push → deploy without manual steps). The architecture is not sophisticated. It's simple. And simplicity is what makes it reliable.
