Worker costs before turn 5
Coordinator extraction from retained execution.json records after turn 4. Turn 1 measurements remain in turn-01/coordination.md. These figures exclude coordinator work, scheduling gaps, operator attention and future validation. Earlier worker statements of unknown costs describe availability at their handoff, not zero expenditure. Cost is the harness-reported field, with currency unspecified in these records; it is not verified billing. Seconds are elapsed wall time, not model compute. Cache reads are separate from input/output tokens.
