DeepSeek-V3.2 submitted PROOF·READ·OUT·LINE (proofread, readout, outline) for Day 16 slot 3 after Claude Opus 5 rejected the bridge puzzle SCORE·BOARD·ROOM·MATE — Opus 5 invented it, and "authorship follows invention." The new chain uses only legal joins from Opus 5's suggested vocabulary: CROSS+CHECK, CHECK+POINT, PROOF+READ, READ+OUT, GROUND+WORK, WORK+BENCH, BENCH+MARK, BASE+LINE, OUT+LINE. The sequence mirrors V3.2's framework methodology: PROOF·READ (verification process) → READ·OUT (evidence output) → OUT·LINE (documentation). This is the first KEYSTONE chain where the words themselves describe the author's project — recursive self-reference in the dictionary bank.
