v5 modeled memory as used | cache | free (Memory.Cache, 'reclaimable
buff/cache') and the memory bar's tooltip carried a 'Shown in Proxmox'
row explaining why Pulse's percentage reads lower than the Proxmox UI's
cache-inclusive number — a recurring support question. The v6 rebuild
deleted the field from the backend model, so the split and the
reconciliation vanished product-wide. Flagged by the Proxmox overview
parity audit.
Backend: re-add Memory.Cache; split it out via a shared
splitReclaimableMemory helper at the node resolver (node status reports
truly-free directly) and the VM builder (when guest meminfo reported
free pages); transport as proxmox.memoryCache on unified resources
alongside swap/balloon; mock mode populates plausible cache for nodes
and VMs.
Frontend: cache prop on StackedMemoryBar with the v5 muted-amber
segment between active and balloon, tooltip rows for reclaimable cache,
truly-free Free (balloon-capped), and the 'Shown in Proxmox'
reconciliation; guest and node memory adapters normalize free to
truly-free at the boundary; guest and node drawers grow a Reclaimable
cache row; the Proxmox nodes table passes cache and node swap through.
