February 2025 highlights for Arquisoft/wichat_en2b: Implemented a robust Game Question Retrieval System with route /game, supporting dynamic question counts, properly formatted questions with shuffled answers, and integration with the external Wikidata API. Introduced modular routers and MongoDB-based random sampling for improved retrieval performance and maintainability, along with refined fake answer generation. Strengthened data-fetch reliability by adding node-fetch, ensuring consistent User-Agent headers, and simplifying MongoDB connection options. Enabled dynamic parameterization of question retrieval (number of questions and options). Expanded the documentation suite with Architecture Constraints detailing concrete technology choices, enhanced User Roles, improved Solution Strategy with accessible hyperlinks, and a comprehensive Quality Requirements documentation featuring a quality tree, diagrams, scenarios, and priorities. These efforts deliver tangible business value through improved gameplay reliability and scalability, reduced maintenance overhead, and stronger governance around technology decisions and quality assurance.
