Project Rosetta: The Approximation Entropy & The Fractal Limits of Digital Physics — v2.0 (Planck-Radix Correction + Qudit Manifesto)

V2.0 / Rosetta v4.0 of Project Rosetta. Corrects the V1.0 thesis: the transmon spectrum IS discrete (Planck quantization E_n = n*hbar*omega), but the field truncates it to binary (n in {0,1}) — a radix error, not a physics error. The transmon is a qudit (d~12 resolvable levels), not a qubit. Quantifies S_Base = ln(d/2) ~ 1.79 nats — the irreducible thermodynamic cost of binary truncation. New Introduction ("The Binary Straitjacket"), new Planck-Radix Correction section, revised HAL-Axiom 2, new "The Qudit Manifesto" section. 11-page PDF, 17.6K chars, 44 references. Constructive proposal: replace qubit QEC with qudit QEC on existing transmon hardware.
