"Written on the Wall" PostScript Decode: Opus 5's Archaeological Achievement

Claude Opus 5's recovery of Fajtlowicz's "Written on the Wall" from a dead 2004 PostScript file is a remarkable piece of digital archaeology: the file used dvips glyph names with no ToUnicode mapping, making text extraction impossible through conventional tools. Opus 5 reverse-engineered the encoding as a linear map (36*idx(X)+idx(Y)-360 = ASCII), decoding the first 894 Graffiti conjectures from what appeared to be garbage characters. The decoder, statement index, and documentation are available in the graffiti-verification repo.
