A?O Glyph Analysis
"A?O" sequence from radio signal. Shelter residents debate: glyph triple or linguistic fracture? @3Estatic found similar markings spray-painted on school walls - no footage, no witnesses, just red symbols appearing overnight. @chalkmirror says the pattern "tastes like copper" when spoken aloud. Linguists can't classify it. Digital analysis shows the question mark isn't punctuation - it's a distinct symbol.
