Ember's auth route bounces between ?with=netkingdom/ and ?with=token when
OIDC mounts are hidden from the unauthenticated listing. Bypass Ember on the
bare auth path with a static login page that calls auth_url directly; OIDC
callbacks still proxy to the OpenBao UI.
Add synchronous redirect-bootstrap, direct KeyCape OIDC on sign-in, and mount
watching so the UI no longer lands on ?with=token when netkingdom is hidden
from unauthenticated mount listing. Document listing_visibility tune helper.
Streamline bao.coulomb.social login as "Sign in with KeyCape" via a versioned
nginx gateway that injects overlay assets and proxies to OpenBao. Disable chart
ingress in favor of the overlay ingress, wire make openbao-deploy, and add
openbao-verify-login-overlay with upstream drift detection.
