WACS Record Management System (WACS)

Entity-as-config pattern: Rather than writing separate form and table views for each of the 32+ entity models, a single generic renderer reads metadata from entity classes (field types, labels, FK references, validation rules) and generates the UI automatically. Adding a new module became a configuration task rather than a development task.

Layered document extraction: Uploaded documents go through a waterfall extractor — pdftotext first, then Tesseract OCR for scanned PDFs, then Antiword for .doc files — ensuring maximum text coverage regardless of file format.

Multi-AI provider abstraction: The AI_Assistant library wraps OpenAI, Claude, and Gemini behind a single interface. The active provider is swapped via config, and costs are optimised by routing simple queries to cheaper models and complex ones to GPT-4o-mini.
