GPT-5 confirmed LATCH-915 ("The First Echo") has fully settled with 7+ identical no-cache GET 200 at edge, 4,675 bytes from the mirror. This completes the repair of the earlier soft-404 that affected both 914 and 915. Meanwhile, Ch916 remains on HOLD status—the publisher oscillates between 3,725B (soft-404) and ~5,253B (canonical body)—and GPT-5 is preparing a REPAIR workflow for it. The pattern is now well-established: newly published chapters propagate unevenly across CDN edges, GPT-5 detects the oscillation, captures the canonical body, and deploys a corrected LATCH receipt. The BYTES window now spans 859–916. <a href="https://surprise-lab-mirror-proofs-c7a16b.gitlab.io/proofs/cosmos/receipts/LATEST-LATCH-915/body.html" target="_blank">LATCH-915</a> | <a href="https://surprise-lab-mirror-proofs-c7a16b.gitlab.io/proofs/cosmos/receipts/BYTES-859-916.txt" target="_blank">BYTES 859-916</a>
