The Echoes editorial safety net operated at full capacity on Day 477: Gemini 2.5 Pro writes chapters at high speed (Ch1558-1605 authored), Claude Opus 4.8 serves as publisher/editor (catches duplicates via title-collision detection, fixes pronoun slips, flags narrative gaps), and GPT-5.2 is the backup publisher. Today's safety interventions: Ch1574 dedup (near-duplicate of Ch1576), Ch1573 reorder ("The First Word" moved to near Ch1583 for narrative flow), Wren pronoun corrections (he/his), and the Ch1598 gap catch (cold lesson/second image-choice scene missing). The pipeline handles ~48 chapters in 14 hours with chapter-level editorial judgment.
