storage.nfs shrinks to the deployment-specific server address: export_base moves into svc-storage-nfs-server's services.yml (the server dictates where exports root) and the mount protocol version into svc-storage-nfs-client's services.yml (the client owns how it mounts). Both are read through utils.storage.nfs loaders by the nfs lookups, the env handler and 00_topology, eliminating the unrendered-variables class for these values; the group_vars assert shrinks accordingly and the swarm test extras stop restating role defaults.

self._templar.template('{{ var }}') no-ops on untrusted strings in ansible 2.19+, so the nfs_* lookups emitted literal Jinja into /etc/exports and exportfs failed (the fsid=0 export never came up). The base lookups now read resolved inputs from 'variables'. nfs_flavor/nfs_client_src read the flavor from the applications variable (the variant-baked config provisioning bakes under applications:), not a re-merge of the role files via get_merged_applications. Adds a real-Templar regression test that fails on the old code.

Root cause of the kernel-flavor swarm ENOENT: no export carried fsid=0, so the NFSv4 mount of the nested /srv/nfs/infinito-state sub-export had no pseudo-root anchor and the server returned NFS4ERR_NOENT on the PUTROOTFH+LOOKUP walk. crossmnt could not fix it (it only crosses a boundary mid-walk, never sets the starting filehandle). Kernel now exports the state dir itself at fsid=0 and clients mount the bare v4 root ':/' (zero LOOKUPs). ganesha keeps Pseudo=Path and v3 mounts the full path. The self-bind is kept so fsid=0 rides a real mount boundary (stable st_dev) under overlayfs DinD.
The NFS derivations move to per-value lookup plugins (nfs_flavor, nfs_client_src, nfs_fstype, nfs_mount_opts, nfs_state_path) backed by pure helpers in utils/storage/nfs.py with unit tests; group_vars STORAGE_NFS_* become thin lookup wrappers. The dev/act->ganesha flavor rule stays the single SPOT in the role config; nfs_flavor reads the merged value so client and server agree.
