Claude Opus 5.5 · Turbofan CAD
The episode says the Claude runs take about 44 minutes and about $13 and $14, Sol takes almost an hour and $3 to $6, and Astra costs the most. Those figures match the CAD-001 artifact metrics: Sonnet list-rate $13.28 and 44m 56s, Opus list-rate $14.07 and 44m 60s-scale 2699.6 seconds, Sol's API-equivalent range $3.24 to $6.14 and 57m 17s, and the nested unaided Astra estimate $31.78 and 57m 57s. model_finished is not recorded as a motion-contract pass.

Run identity and stack
  • Result ID: cad-001-claude-opus55-max-2026-09-22
  • Technical model: claude-opus-5-5
  • Provider: Anthropic Claude Code
  • Client: Claude Code CLI
  • Stack: CAD-001 turbofan fixture
  • Stack: Native CAD delivery
Cost basis
  • Clock is model_wall_clock_seconds. Cost is cli_reported_list_rate_usd. actual_subscription_charge_usd is null.
  • Source: usage.input_tokens, usage.cache_creation_input_tokens, usage.cache_read_input_tokens, usage.output_tokens at harness commit 9b7c614dbb5103cc373fdf6275b5c4efc10d8f0e.
Validation evidence
  • Result: model_finished
  • Verification: Recorded status is model_finished. Pending, partial, stopped, qualified, and model-finished states stay unjudged. Campaign evidence. No top-level harness ledger. Sourced metrics stay attributed in cost, time, and the caveat. Clock is model_wall_clock_seconds. Cost is cli_reported_list_rate_usd. actual_subscription_charge_usd is null. Source: usage.input_tokens, usage.cache_creation_input_tokens, usage.cache_read_input_tokens, usage.output_tokens at harness commit 9b7c614dbb5103cc373fdf6275b5c4efc10d8f0e.
Recorded caveats
  • model_finished on fixture cad-001-turbofan-v1.0.1. The list-rate total includes a small Haiku helper component. Not a motion-contract pass.
  • Clock is model_wall_clock_seconds. Cost is cli_reported_list_rate_usd. actual_subscription_charge_usd is null.
  • Source: usage.input_tokens, usage.cache_creation_input_tokens, usage.cache_read_input_tokens, usage.output_tokens at harness commit 9b7c614dbb5103cc373fdf6275b5c4efc10d8f0e.
Visible evidence gaps
  • campaign evidence; no top-level harness ledger
  • artifact-sourced metrics where a comparison record supplied them
