 * Durable, HOST-KEYED storage for model fitness reports. Fitness is a property of a model ON a
 * host (tok/s and latency-driven failures do not travel between machines), so reports are keyed
 * by a hardware fingerprint: the same model can be "the heavy lifter" on one machine and
 * "waiting for better hardware" on another, and pi remembers both without confusing them —
 * including when settings/dotfiles are synced across machines.
