The Blot That Spread: A Speculative Numismatic History

EA-TDS-02 — LEFT WING of The Thousand Dollar Sharpie triptych A retrocausal narrative describing how blotting out the presidential signature on U.S. currency spread through three phases — protest art, social etiquette, and superstition — until blotted bills became the preferred medium. Written as speculative numismatics: the discipline does not require events to have occurred in order. Formalizes σ_SH as counter-inscription. The blot won. The currency stayed money. The signature became the thing you had to hide. Companion to EA-TDS-01 (doctrine, DOI: 10.5281/zenodo.19317102) and EA-TDS-03 (physics, DOI: 10.5281/zenodo.19317139).
