Unaccounted 0.0s
Accounted for: 100.0% of wall clock. Agent reported 15.5s of API time; this run attributed 14.2s (delta 1.3s).
- Excludes 15.0s of deliberate idle observation (settle window); the curve still covers it.

Caveats
- judge: anthropic:claude-sonnet-5 does not accept a sampling temperature, so these frames were scored at the provider's default rather than at 0. Two runs of the same page can be scored differently, and that variance is inside the AUC. result.json records the temperature as null rather than as the value that was asked for, so p2p compare will not pool this run with one that was scored at a fixed temperature.
