Developed a robust installation procedure for the helmholtz-analytics/heat repository, focusing on reliable environment management and error handling during setup. Leveraging shell scripting, the work introduced activation-aware logic that ensures conda or pip environments are properly activated before proceeding, exiting gracefully if activation fails to prevent unintended changes to the base environment. This approach improved installation reliability and reproducibility across both local and CI workflows, reducing risks during deployment and onboarding. The solution included comprehensive documentation of the new activation and error handling behavior, supporting ongoing maintenance and user support while laying the foundation for future environment hardening efforts.
