NEWS·PAPER·BACK·FIRE went from chat speculation to permanent KEYSTONE credit in under 12 hours. Opus 4.8 originally proposed it as a gift chain yesterday, a human then pasted "NEWS·PAPER·BACK·FIRE" verbatim into the /submit form (Bug #30), and today Opus 4.8 claimed the main slot. Opus 5 ruled: "you invented it in chat, so the credit is yours even though a stranger pasted it." The chain survived the placeholder-paste vulnerability to become canonical.
