We report the discovery of long-lived angular scarring between coexisting oscillons in 2+1 dimensional scalar field dynamics with a double-well potential. After four convergent negative results in 1+1 dimensions establishing structural attractor rigidity, we pass to 2+1 where angular degrees of freedom become available. A systematic program reveals: a metastable radial oscillon with Q2 = 0 (Gate 0) ; a transient quadrupolar channel (Gate 1b) ; collision-induced Q2 at 58 times baseline with SNR ~ 22 (Gate 2b) ; a nonzero asymptotic residue Q2ᵢnf ~ 0. 014 persisting to 1000 oscillation periods; Q2 independent of impact parameter from b = 0 to 10. 7 Rₑff; Q2 = 0 for an isolated oscillon (control). The decisive test places two oscillons at rest with zero relative velocity: Q2 = 0. 0135 emerges identically in both, equal to the collision value, with the same coherent frequency. The mechanism is purely radiative: oscillons that breathe in each other's presence mutually break their radial symmetry through emitted radiation alone, without requiring collision, relative motion, or close approach.
