Public summary

Claude Fable 5.1 Max partial_artifact_and_rounded_usage_ledger ledger: 54m (rounded provider display) wall-clock, Not recorded, and $17.71 provider-reported session cost; not independently recomputable from the rounded display.

Run identity and stack
  • Result ID: neo-gothic-storm-city-fable-5.1-max
  • Technical model: claude-fable-5.1
  • Provider: Anthropic Claude Code
  • Stack: Anthropic Claude Code
  • Stack: Technical model/configuration: claude-fable-5.1
  • Stack: TWIGL fragment shader
  • Stack: Harness v1 neo-gothic storm city prompt
Cost basis
  • No raw session export, exact input-token values, cache TTL, or per-line price receipt was supplied.
Primary artifact integrity
  • Kind: twigl-fragment-shader
  • Path: artifacts/neo-gothic-storm-city-fable-5.1-max/source/drowned_spires_twigl.frag
  • SHA-256: 3963cc3e9e2c02993caaec87e9c1da86f120a8dc1dc2b3814755e17687dea483
Recorded caveats
  • Wall-clock and API duration are whole-minute values displayed by the provider; they are not raw timestamps.
  • The provider abbreviated several token values, so the recorded 11,098,018 processed-token total is an approximation from displayed components.
  • The $17.71 total is provider-reported and is not a verified API-equivalent cost calculation.
  • The rolling local-activity request totals in the report are excluded because they are not session-attributed model-call counts.
  • Static GLSL ES compilation is not a TWIGL runtime or visual-quality check.
Visible evidence gaps
  • raw Claude Code session export or exact machine-readable token receipt
  • per-line pricing and cache-TTL receipt sufficient to recompute cost
  • TWIGL runtime receipt
  • initial and optimized local FPS under identical conditions
  • RTX Pro 6000 1080p60 final render
  • blind-evaluation record
