## Reading
Track B FC design targets (5 microVMs/core/sec, ≤5 MiB overhead) are not met
by this flux-vm sandbox cold-create path (~28–65s create, ~5.5 MiB VMM RSS).
Use Firecracker warm pools / snapshots for density claims; this archive is a
host baseline for H5, not a product density identity claim.
