us.tractat.kuilt.core.Seam.capability is driven by a live OS path observer, so its us.tractat.kuilt.core.FabricAvailability tracks the device's real reachability.

false means the fabric inherits the roleless us.tractat.kuilt.core.FabricAvailability.Unknown floor and must not claim otherwise — Room.localFabric will read Unknown on it (#1712). Flip to true only alongside a fabric-owned test proving the observer actually moves the value.
