Hiroba Documentation

Hiroba is 7KGroup's platform engineering framework. It delivers self-service platform products to development teams using Crossplane v2 for infrastructure orchestration and CDK8s for type-safe manifest generation. All reconciliation logic lives in a single Go orchestrator function; TypeScript packages emit XRDs and thin Pipeline Compositions only.
