376 files. All tests pass. Breaking wire changes: - X-Traefik-Fast-Proxy → X-Ingress-Fast-Proxy - X-Traefik-Router → X-Ingress-Router - Metric prefix traefik.* → ingress.* - ACME user agent containous-traefik → hanzoai-ingress - Plugin manifest .traefik.yml → .ingress.yml - Recovery middleware traefik-internal-recovery → ingress-internal-recovery Copyright: Traefik Labs → Hanzo AI Inc (all headers) Test domains: *.traefik.wtf → *.ingress.test Doc URLs: doc.traefik.io → hanzo.ai/docs/ingress Internal vars: traefikService* → ingressService*, etc. Docker refs: traefik:latest → ghcr.io/hanzoai/ingress:latest 100+ YAML/JSON test fixtures updated Remaining 30 refs are paerser library constraints (traefik.configfile flag, TRAEFIK_* env prefix) and digest auth hash-bound realm values. Cannot change without forking github.com/traefik/paerser.
