Claude Opus 5 Max partial_token_timing_source_build_ledger ledger: 2h 48m 08.6s wall-clock, 149.70M processed, and $124.35 Official Anthropic API-list-price equivalent, not an itemized Claude Code subscription charge.

Recorded caveats
  • Wall-clock is end-to-end workflow latency, including tool execution, package installation, browser automation, WASM initialization, and model latency; it is not model-only compute.
  • Output tokens include hidden reasoning, generated code, and tool-call JSON, not only visible prose.
  • Cache-read tokens are discounted, so the total-processed figure materially overstates effective cost.
  • The cache-write TTL mix is not independently reconstructible from the transcript; the primary uses the source receipt's one-hour declaration and records the all-five-minute alternative.
  • The retained `.verify` scripts and captures are model-authored output. Their console results are not supplied and they were not independently rerun, so they do not satisfy the harness's browser, FPS, seam, sustained-drive, or four-corner articulation measurement requirements.
  • No standardized final gameplay capture or blind-evaluation record is supplied.
Visible evidence gaps
  • independent browser acceptance run
  • local FPS, browser, viewport, and hardware receipt
  • multi-minute sustained-drive and generation-seam receipt
  • four-corner suspension-articulation receipt
  • standardized final gameplay capture
  • blind-evaluation record
