Month: 2026-05 | Focused on stabilizing the bootlin/training-materials repo by fixing a critical clone issue and preserving build reliability for training materials. The main fix corrected the URL for the k3-image-gen repository to resolve a 403 during clone, preventing blocked onboarding and CI failures. This work enabled downstream automation and ensured training content could be fetched and built without manual intervention.
