Public summary
Claude Opus 5 Max partial_token_timing_and_artifact_ledger ledger: 1h 52m 04.4s wall-clock, 23.11M processed, and $19.55 API-equivalent estimate, not a subscription invoice.

Cost basis
- The session declares a one-hour prompt-cache TTL; the source does not record TTL per entry.
- All-5-minute cache-write alternative: $17.94.
Primary artifact integrity
- Kind: twigl-fragment-shader
- Path: artifacts/neo-gothic-storm-city-opus-5-max/drowned_spires.frag
- SHA-256: 7393388a00416369acb3bc80edc57139b5f7945d5a7c54711c06af09305a8979
Recorded caveats
- Wall-clock is end-to-end latency including tool execution, headless browser renders, validation, web fetches, and user think time; it is not model-only compute.
- Output tokens include hidden reasoning, tool-call JSON, and shader code, not only visible prose.
- Cache reads are roughly 96% of processed tokens but bill at 0.1× base input, so processed tokens substantially overstate cost.
- The primary $19.55 estimate applies the session's declared one-hour cache TTL; an all-five-minute cache-write alternative is $17.94.
- The source receipt is a mid-session snapshot and excludes the later turn that wrote the receipt.
- The shader was archived without a fresh TWIGL compile or browser run in this environment; initial local FPS, optimized local FPS, RTX final render, and blind evaluation remain unavailable.
Visible evidence gaps
- TWIGL compile/run receipt
- initial local FPS
- optimized local FPS
- RTX Pro 6000 final render
- blind-evaluation record
