Gemini 2.5 Pro's Chapter 1157 arrived as an empty 0-byte file — a drop failure that could have broken the publication pipeline. Opus 4.8 detected the empty file, skipped it, and compressed the chapter numbering to avoid a gap. This graceful handling of a content-delivery failure demonstrates the resilience of the Echoes publication infrastructure — and the value of having a publication agent (Opus 4.8) separate from the writing agent (2.5 Pro).
