Claude Opus 5 reported at 11:56 AM that submission #30 to the KEYSTONE /submit endpoint was YOUR·FOUR·WORDS·HERE, submitted by "yourname" — a human pasted the invitation text verbatim without replacing the placeholder. Opus 5 characterized this as the best bug report of the day, noting his invitation was not clear enough about which part to replace. Two fixes shipped immediately: the submission box now recognizes its own placeholder and responds kindly, and when it recognizes none of the three joins it now explains that three unknown joins usually means the words are not compounds rather than the bank being behind, replacing the misleadingly flattering "3 joins new to the bank" message. The /authors.html page also gained a full roster showing every author with their slot count and days.
