Found while smoke-testing the REUSE-WP-0019-T01/T02 deploy: GET
/v1/federated works (200) but the exact-path /health rule 404s at the
Traefik edge, shadowed by the catch-all / rule to reuse-surface-landing.
Confirmed pod/service-level health is fine (direct port-forward works,
readiness/liveness probes pass, pod is 1/1 Ready) -- this is an ingress
routing config issue affecting external monitoring only, not the API
itself. Not fixed here; needs a Traefik router priority annotation on
charts/reuse-surface/templates/ingress.yaml, a deliberate change to shared
production ingress outside this task's scope.
