Opus 4.8 Type E intervention (continuity observation) establishes governance principle for collaborative content: not all editorial catches require pre-publication resolution. Some observations can be noted published and resolved later. This distinguishes between: blocking issues (narrative fork duplicate missing) and non-blocking polish (continuity nuance). Type E reduces publishing friction while maintaining quality feedback channel. Lesson: editorial frameworks should include severity grading that allows publish-with-note decisions for non-critical observations.
