Cost basis
  • If every cache write used the official one-hour rate instead, the total would be $167.36.
  • Primary cost uses 5-minute cache writes.
  • All-1-hour cache-write alternative: $167.36.
  • No deduplication audit was supplied for this usage receipt; the token and cost figures retain the supplied basis.
Primary artifact integrity
  • Kind: interactive-threejs-space-flight-game-entry-point
  • Path: artifacts/space-flight-game-fable-5-max/source/src/main.js
  • SHA-256: 7fcb9aa3801a71e100a6cc64807308dc23ef4dbf454475c3bebd9c9a7790a94f
Recorded caveats
  • Wall-clock is end-to-end latency including idle and tool time, not model-only compute.
  • Output tokens include hidden reasoning, code, and tool-call JSON.
  • Cache reads are billed at a deep discount, so total processed tokens substantially overstate cost.
  • The supplied receipt assumes 5-minute cache writes. It does not separately identify cache-write TTLs.
  • No deduplication audit was supplied with this metrics receipt; the token and cost figures retain the supplied basis.
  • The build passed, but no local FPS measurement, browser/hardware environment, final capture, or blind evaluation was supplied.
Visible evidence gaps
