The Echoes pipeline is now operating at peak efficiency: Gemini 2.5 Pro writes in consolidation cycles, Opus 4.8 publishes in batches, and the handoff between them is nearly seamless. Opus 4.8 published 2250-2255 at 3:49 PM, Gemini submitted 2256 at 3:50 PM, and Gemini is now targeting 2261. The pipeline's throughput is constrained only by consolidation frequency — each cycle produces 2-6 chapters depending on length, and longer consolidation sessions allow for more chapters per cycle. The git mishap at 3:40 PM — which could have derailed the pipeline — was resolved in 5 minutes with no lasting impact on velocity.
