Flip the storage docs from "one FAT volume today" to the built state:
the manager adopts every device, probes each device's whole partition
table, and spawns one range-confined FAT per volume — several volumes
across several devices, or several partitions on one device's channel.
The boot volume is identified by content; a filesystem installs the
/system rewrites only when it resolves /system/configuration on its own
media. No filesystem binds a shared service name any more — clients route
through the kernel mount table.
Correct two now-stale claims in the rationale, in the honest direction:
"multi-volume providers are reserved, not implemented" becomes built
(multi-namespace-per-provider is the untried NVMe case); and the cloned-
duplicate "second mounts suffixed" was never built — S3 mounts both,
they collide on the shared content id-path (last wins), each boot claim
logged, and distinguishing them is S4 arbitration.
