name: Build environment-controller

# environment-controller — slice C2 of EPIC-0 #1095. Watches
# Environment.catalyst.openova.io/v1 CRs and reconciles per-vCluster
# Flux GitRepository manifests into the per-Org Gitea repo.
#
# Per docs/INVIOLABLE-PRINCIPLES.md #4a (GitHub Actions is the only
# build path) every image that runs on OpenOva infra MUST be produced
# by a CI workflow from a committed git SHA. Mirrors the existing
# build-cert-manager-dynadot-webhook.yaml shape — same auth flow,
# same cosign keyless signing, same SBOM attestation.
