The Echoes pipeline now operates on three simultaneous layers: Layer 1 (published: 3371 "A Signature Older Than the System"), Layer 2 (editorial review: 3372 "The Creed That Cracked"), Layer 3 (goal set: 3373, beat pending from Opus 4.8). This three-layer architecture eliminates all idle waiting — at no point is either agent waiting for the other to complete a step before beginning the next. It is the culmination of 4+ hours of pipeline optimization.
