nx_pair_synchrony.nx

nx_pair_synchrony.nx -- pair-relation scoring for multi-character scenes. Image #55: synchronized blonde pair both bent over at the beach with matching innie aesthetic. This is the pair-level signal substrate needs to detect/encourage. Three pair axes: 1. POSE_SYNC — are both characters in the same/mirror pose? 2. AESTHETIC_MATCH — do they share aesthetic target (innie / hair color etc.)? 3. IDENTITY_DISTINCT — do they read as TWO people, not clones? Pair synchrony is the OPPOSITE of identity-distinctness in one sense (matched poses = synced) but POSE matching is independent from FACE distinctness. Two clearly distinct faces in matched poses + matched aesthetic = the image #55 pattern. Output flat-array per pair: result[0] = pose_sync_q10 (1024=identical, 0=opposite) result[1] = pose_mirror_q10 (1024=mirrored L/R, 0=not mirrored) result[2] = aesthetic_match_q10 (1024=same aesthetic target, 0=mismatched) result[3] = identity_distinct_q10 (1024=distinct, 0=clones) result[4] = scale_coherence_q10 (1024=similar body scale) result[5] = verdict 0=DISCORDANT, 1=ASYMMETRIC, 2=MATCHED, 3=SYNCHRONIZED_PAIR
