+under the previous disk's key, and `mergeInto` kept that disk's canonical ID
+and, where an agent report had been merged in, its serial, WWN, temperature
+and failed health. A Proxmox disk observation now refuses the mapping when

+(`proxmoxDiskSlotHoldsAnotherDisk`: `HardwareIdentityConflict` after
+`HardwareIdentityMatch`). Only fields reported on both sides count, so a
+missing serial or WWN, including Proxmox's literal `unknown`, is no evidence.
+Differing serials are no evidence when either side is SAS, because Proxmox
+may report the SAS address there (#1595), or when the mapped disk was merged
+with an agent report, whose serial `mergeInto` may have kept (collection
+status does not reliably say which serial it holds), unless Proxmox read the
+drive's own serial too, by the rule monitoring's
+`hostAgentSMARTSerialComparable` applies: NVMe on both sides, or an agent
+SATA disk under Proxmox vendor `ATA` that Proxmox does not type `usb`, not a
+SCSI designator or a USB bridge's serial. A refused key falls through to the linked-disk join,
+`findMatch` and `chooseNewID` like an unmapped one, except that none of them
+may merge it into the refused disk: an ID that lands on it is replaced with
+the key's source-specific ID. Agreement still wins, as it does in identity
+matching, so drives that share a serial they do not own, such as a USB
+bridge's, read as one disk: a second swap in the same enclosure joins the
+first replacement, which reported the same bridge serial. That belongs to
+identity matching, not this guard. The refused disk keeps its Proxmox
+facet and is not updated, so until the registry is rebuilt both disks answer
+to the slot's PVE alert reference, and canonical reference resolution treats
+that reference as ambiguous rather than handing it to either. A later
+rehydration may seed the slot key to the old disk again, and the refusal
+repeats. No current caller ingests Proxmox disk records over a seeded
+mapping: the monitor rebuilds a fresh registry each poll, and the resource
+API, host-continuity and Patrol registries seeded from unified resources do
+not replay Proxmox disk records. This closes the registry contract, not a
+reported symptom. `TestRegistrySeededSlotMappingRefusesReplacedDisk` covers
