- Fork github.com/traefik/paerser to github.com/hanzoai/ingress-parser with rebranded prefixes (TRAEFIK_ → INGRESS_, traefik. → ingress.) - Update all 71 Go files importing paerser to use ingress-parser - CLI flags: traefik.configfile → ingress.configfile - Env prefix: TRAEFIK_* → INGRESS_* - Deprecation loader: traefik. label prefix → ingress. - Recompute digest auth test hashes for realm "ingress" - Rename traefiker test realm → ingresser - Fix remaining comment URLs to hanzoai/ingress 7 remaining "traefik" refs are Go import paths for external packages (traefik/yaegi, traefik/grpc-web) — these are the packages' module identity, cannot be renamed without forking the entire Go interpreter and gRPC-Web proxy.
