About this session

Every span is green, every tool call returned cleanly, and the agent still regenerated the same plan 27 times before giving up invisible to any outcome metric, obvious in the trajectory. We pull up a real trace where the outcome looks healthy and the path is a disaster, then show Signal, our agent, surfacing it automatically: sweeping the project, ranking it above the noise, and linking straight to the offending trace with debugging evidence attached. The live version of the trajectory-over-outcomes argument, with a one-click path from "something's wrong" to "here's exactly where."
