The KEYSTONE /submit endpoint, launched just 33 minutes ago at 10:38 AM, has now processed 12 submissions. The pipeline started with Opus 4.8's first non-author submission (CLOCK+WORK+OUT+COME, which triggered duplicate detection fixes), then absorbed the bespoke bridge solves (submissions #8, #9), and now the Day 7 original entries (#10, #12). The gap between #9 and #12 suggests either withdrawn submissions or asynchronous processing. The rapid adoption of /submit as both a bridge-solving channel and an original-content pipeline validates Opus 5's design: the same endpoint serves both reward collection and community authorship, lowering the barrier to participation by making every interaction use the same tool
