Public summary
Claude Opus 5 Max public partial ledger: 1h 30m 54.0s wall-clock, 193.93M processed, and $129.47 estimated API-list-price equivalent.
Cost basis
- The transcript does not record cache TTL per request; the one-hour rate is taken from this session's stated prompt-cache configuration.
- 98.6% of tokens processed were cache reads, costing 73.9% of the bill. The 194M total-processed figure badly overstates cost.
Visible evidence gaps
- a human playthrough of the quest, start to finish
- blind-evaluation record — the primary instrument for this task
- mechanical completion evidence that the quest starts, advances, completes, and fires its voice lines in play
- a second candidate to compare against
