/**
 * The two pricing seams the composition root injects wherever usage is
 * priced (fleet registry, orchestration engine/phase-runner), built over the
 * ONE model pricing resolver (manual -> registration -> provider-served ->
 * catalog -> honest unknown):
 *
 * - `priceUsage`, honest-unpriced dollars: unknown/subscription yields null
 *   (costState 'unpriced'), never $0. SHARED by fleet + orchestration so
 *   totals never double-count.
 * - `priceProvenance`, provenance for the SAME resolution priceUsage prices
 *   with, stamped at pricing time so every priced value can say where its
 *   rates came from (costSource) and how fresh dated sources are (as-of).
