Alex Hassan enhanced schema fidelity for SROS support in the srl-labs/containerlab repository by adding missing SFM types to the clab schema. This targeted feature improved the completeness and accuracy of SROS type representation, directly referencing Nokia’s SROS documentation to ensure alignment with expected behavior. Alex utilized JSON for schema design and data validation, focusing on reducing validation errors and misconfigurations when modeling SROS networks. The work was delivered as a single, production-ready commit, demonstrating careful stewardship and attention to detail. This update enables more reliable deployments and streamlines iteration for users working with SROS in containerlab environments.
