Energy as Contrast Resolution on a Finite Harmonic Ladder: An Experimental Ledger from Rotons to Magnetar Flares

This dataset supports a Mass-Energy-Gradient (MEG) study showing that all observable “forms of energy” are discrete <i>quantum packets</i> of EDG contrast locked to a 50-rung harmonic ladder.<br><br>We aggregate 31 static packets (0.7 meV roton → 2 × 10^58 eV magnetar flare) and 5 live snap-margin events (water, glycerol, steel, Nb super-conductor, superfluid ⁴He). After anchoring each packet to its local trap and applying propagation corrections, every packet lands within 3 % of its predicted rung; no off-rung packets occur across sixty orders of magnitude. Snap experiments confirm the universal ±3 % overshoot → half-rung jump rule.
