Hanzo CI/CD / cicd (push) Failing after 9m46s
CI/CD / cicd (push) Failing after 10m4s
Most of it was stale, not cosmetic: the docs taught `TRAEFIK_*` env, `traefik.http.*` labels, `traefik.ingress.kubernetes.io/` annotations, `.traefik.yml` plugins and `traefik_*` metrics. This binary answers to `INGRESS_*`, `ingress.http.*`, `ingress.kubernetes.io/`, `.ingress.yml` and `ingress.*` — a reader following the old text configured nothing. Two were worse than stale. Gateway API examples gave `group: traefik.io` for an IngressService backendRef, which kubernetes.go:1265 refuses against hanzo.ai. The contributing guide built with `github.com/traefik/ingress` ldflags against a module that is `github.com/hanzoai/ingress/v3`. script/code-gen.sh globs `hanzo.ai_*.yaml` and matched nothing — the per-CRD dumps had been deleted and never regenerated, so `cat` failed the script under `set -e`. controller-gen v0.19.0 restores all ten; they concatenate byte-for-byte into the committed definition and fixture. CHANGELOG.md is untouched: 6,789 lines of imported release history, where a rewrite would falsify the record rather than rebrand it. `@traefiklabs/faency`, `traefik/whoami`, k3s's `--disable=traefik`, the `traefik.io` CRD group and the MIT attribution stay — upstream's addresses, not our brand.
