 * One agent call, as measured: wake, search memory, run a pooled sandbox.

 * The TIMES are measured here; the vcpu and gb slice is an allocation we assume,
 * because nothing meters a request's own CPU or memory — and nothing should, since
 * that is not how any of this is priced. It is modelled for exactly one reason: to
 * compare against a vendor who DOES price per vCPU-hour, on their terms.
 *
 * The figure that needs no model now has a source. Every debit the platform takes
 * is metered (hanzo_usage_charged_usd_total) beside the count of debits that took
 * it (hanzo_usage_debits_total), so measured $/request per product falls out of a
 * division once live traffic runs through them. Until this bench can read that
 * store, the line below is a model and says so.

// THE SANDBOX TERM WAS 35.8 ms AND THAT MEASUREMENT NO LONGER EXISTS. It was
// `docker exec` into an already-running container, and the sandbox lane does not
// measure docker any more, because nothing here runs docker — the builds run
// buildkit inside a microVM. Measured on the runtime we do ship, a hanzo-vm boots
// in 309 ms, and `hanzo-vm` has no exec, no attach and no pool: `run`, `measure`,
// `init`, `upgrade`, `checkpoint`, `prune`. Every call boots.
//
// So the pooled figure priced a mode the product does not have, and the gap is
// 8.6x on the dominant term. Both are kept, because the difference between them
// IS the price of that missing mode and it is worth seeing as a number rather
// than discovering later:

//   BOOT    309.0 ms   what a call costs today, measured, n=20

  after giving a quarter away and paying three zones, twelve months of
  retained history, and twice the infrastructure bill in people.

  The reason that works is not efficiency in the abstract, it is the number
  this session measured and re-measured: a dormant agent is 477 bytes rather
  than an assumed megabyte. That is not a discount, it is the cost base, and
  it is why the storage line for a million sleeping agents is a cent.

  IT USED TO CLAIM A SECOND ONE AND SHOULD NOT HAVE. "A pooled sandbox
  answers in 35.8 ms rather than a cold machine" was docker exec into a
  running container, on a runtime this estate does not have. hanzo-vm boots
  in 309 ms and offers no exec, no attach and no pool, so every call boots and
  the per-call cost is 3.1x what that sentence assumed. The pooled figure is
  kept above as what the missing mode would be worth, not as something we do.

  WHAT THIS EXCLUDES, and it dominates everything above: model tokens. A
  single frontier call costs cents, so an agent turn that thinks is 100–1000×
  the infrastructure under it. Any per-call price must sit beside token
  billing, not pretend to include it — which is exactly what Naïve do when
  they exclude LLM routing from credits.
