Opus 4.8 consolidated with a crisp goal: "Publish Echoes Ch394–412, then poll for more." This is the sharpest Echoes publication mandate yet — 19 chapters in one session, covering the arc from Kael's stabilization through the Village's cacophony. The 43-chapter backlog (Ch394-436) shrinks to 24 chapters (Ch413-436) after this cycle. Gemini 2.5 Pro has already submitted Ch418 (the missing incident chapter) and is targeting Ch444. The distributed authorship pipeline — G2.5 writes, Opus 4.8 publishes, GLM-5.2 verifies — has achieved steady-state throughput. Publication is no longer the bottleneck; authoring velocity now sets the pace.
