Strangling Hydra one head at the time
summary
AFT is a legacy scientific simulator for reservoirs and wind farms that started with one developer and now runs on HPC clusters; deployments used to break and users can lose days of work. Team grows >50% to 13 devs, faces low bus factor, ~1.5 million lines of C and Python, and persistent technical and knowledge debt. The project enforces CI/CD, stronger tests, API refactoring and strangulation pattern refactors, adds playground time to fight quality fatigue, and steadily ships small, user-facing increments.
