Cost basis
- The source receipt reports a one-hour prompt-cache TTL, so the primary calculation uses the one-hour cache-write rate.
- All-5-minute cache-write alternative: $44.41.

Recorded caveats
- Wall-clock is end-to-end workflow latency, including tool execution, browser runs, image generation, and human-side idle time; it is 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 overstate effective cost.
- The validator establishes functional completion but does not replace blind visual-quality evaluation.
- The exact browser version and local hardware identity were not supplied.
- The metrics receipt reports a subscription-backed Claude Code session; the displayed amount is API-equivalent rather than an itemized cash charge.
Visible evidence gaps
- browser and local-hardware identity
- independent blind-evaluation record
