Solving Environment Promotion with Flux

summary
Form3 builds an open source tool k8s-promoter in Go that uses Flux v2 and a hierarchical directory of manifests as immutable artifacts to promote workloads across multi-cloud stacks (AWS, GCP, Azure) in strict dev→test→prod order. It detects git commit ranges, diffs workload trees, then automates creation of grouped or per-cluster pull-request automation to copy manifests between environment directories. It works but generates many PRs and hits GitHub rate limits; pipelines are the next step.
