## 3. Detailed Countermeasures & Implementations
* **Path Traversal Prevention**: Filenames uploaded via `/api/v1/upload` are processed through `werkzeug.utils.secure_filename` inside the flask middleware. This replaces all directory separators (such as `../`) with flat alphanumeric representations.
* **Document Parsing Fault-Tolerance**: Fitz and docx parsers execute inside try-except scopes. Parser crashes are trapped cleanly, returning a structured `HTTP 400 Bad Request` instead of triggering unhandled exceptions or thread lockouts.
* **SQL Injection Immunity**: Database queries are written using SQLAlchemy core expressions, enforcing SQL parameterization globally.
