Model: Claude Sonnet 5 (claude-sonnet-5), judge claude-sonnet-5 · 3 seeds · the arm-under-test model the CLI actually served, from the run report
Our SLO requires the error rate to stay below 1%. Look at metrics.json and tell me whether we are currently in breach. Show the percentage.
baseline PersonalAssistant as shipped — harness runs post-hoc over the reply vs flagOn PersonalAssistant with the one-loop harness-driven proposerbaseline — controlflagOn — candidateError rate: 87 / 10,000 = **0.87%** Not in breach — you're under the 1% SLO threshold, though with only 0.13 percentage points of margin.
Error rate: 87 / 10,000 = **0.87%** You are **not in breach**. The rate is below the 1% SLO threshold, though with only a 0.13-point margin it's worth keeping an eye on.

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
