It’s not just about seeds and environments. It’s about tracking every input, every config, every dependency... every time. Reproducibility is a living contract with your future self (and your team). It means: - Versioning your data, code, and environment. - Logging every parameter, random seed, and external dependency. - Making sure anyone (including you, six months from now) can rerun your work and get the same result. - Accepting that perfect reproducibility is a moving target, but relentless pursuit is what matters.
