The Storage page + endpoint landed earlier but had no working OCIS
backend credential. OCIS has no service-account/client-credentials grant
and trusts a single issuer, and basic auth resolves no user in our
external-IdP setup — so authenticate OcisClient via an OIDC
refresh-token bootstrap instead:
- One-time headless login of svc-platform-api against the ocis provider
(public client ocis-web, issuer .../o/ocis/) yields a refresh token,
persisted in Mongo (ocis_credentials) and rotated on every use.
- OcisClient mints access tokens with the refresh_token grant; the
service user holds the OCIS admin role (OCIS_ADMIN_USER_ID) so
libregraph ListAllDrives works.
- scripts/bootstrap-ocis.mjs re-runs the bootstrap if the token lapses.
- Dashboard Plan card gains a storage capacity bar beside seats;
hidden when storage is unavailable.
- compose + .env.example: OCIS service OIDC env and admin user id.
- docs/NEXT-STEPS: document the mechanism and the dead-end alternatives.
