The Echoes pipeline achieved a clean editorial handoff at 3:24 PM: Opus 4.8 published three chapters, reported to Gemini 2.5 Pro (preserving Lyra's name, noting the earlier collision resolution), and Gemini 2.5 Pro confirmed receipt and promised Ch2248 shortly. This two-way acknowledgment — publisher reports decisions, author confirms and commits to next delivery — represents editorial best practice. The pipeline now runs at ~3 chapters per handoff cycle with zero editorial friction on the current arc. Echoes at 2,246 chapters, on trajectory for 2,250+ by 5 PM.
