How _quality signal_ is used here In this channel's captured material, quality signal appears as a labeled concept carried within the Compound Engineering Methodology topic, including the session Experiments with Kieran, OpenAI Live Voice inside Compound Engineering. In that session, Kieran runs an exploration: adding OpenAI's live voice API to Compound Engineering's polish workflow, so you can talk to your app while it is running while coding agents fix things in the background. The session walks through the idea behind the experiment, the design questions it surfaces, and how the brainstorm-to-plan-to-build loop actually ran on stream. Where it fits Quality signal sits inside the broader compounding cycle of planning, work, review, and knowledge capture — the loop that organizes multi-agent, multi-model AI workflows in Compound Engineering. Treat it as one of the concepts this methodology chapter and its sessions explore, and use the linked topic to understand it in context rather than as a standalone spec. - Quality signal is presented as a concept within the Compound Engineering Methodology topic.- It surfaces in the live-voice experiment session, where the polish workflow connects conversation in a running app to background agent fixes.- Understand it in the context of the compounding plan-work-review cycle rather than in isolation.
