Indeed no gold star. I've had too mangy AHJs as well as engineers selectively quote parts of codes and leave out exceptions they didn't like, change a single word that changes the entire meaning (this is common in NICET questions where the exact wording in the code is the only correct answer among many that essentially say the same thing but are incorrect), or reference a piece of code that seems to apply but doesn't (the internal galvanizing requirement thread from the beginning of the week?). For this issue though there is the consideration of the accumulation of debris under the first landing but in the case where the space is enclosed, regardless of accessibility,this is also not an issue.
