REWIRE aims to make computational reproducibility an integral part of European research culture. The project focuses on mobilizing communities and driving cultural change by embedding reproducible practices at the natural points of the research lifecycle. We will deploy machine-actionable Reproducibility Management Plans (design), Guix-based computational environments (execution), and RO-Crate packaging (publication), supported by tailored training and peer learning. Evidence from pilots and follower organisations, with a focus on widening countries, will inform four major results: the BLUEPRINTS of implementation pathways, a validated technical PLAYBOOK integrated with EOSC services, a role-specific Training Package with Train-the-Trainer, and the REWIRE Network for sustained community exchange. By project end, research communities will have embraced reproducibility as standard practice, reinforced by shared guidance, stewardship, and an active European network.
