Given ordered points Pi = (xi, yi), i = 0..N-1 gap_i = distance(Pi, P(i+1)) - (ri + r(i+1)) normalized_gap_i = gap_i / min(W,H) gap_ratio_i = gap_(i+1) / max(gap_i, ε) size_ratio_i = r_(i+1) / max(r_i, ε) Direction vector: v_i = normalize(P(i+1) - Pi) Turn angle: θ_i = acos( clamp(dot(v_(i-1), v_i), -1, 1) ) Rhythm consistency: CV_gap = std(gap_i) / max(mean(gap_i), ε) Important: CV_gap ≈ 0 → mechanical uniform rhythm moderate CV → controlled variation high CV → broken rhythm / possible cluster

Path constraints: mean_turn_angle <= 35° for smooth directional rhythm single strong turn <= 95° if composition uses L/Z structure avoid repeated micro-zigzags: if sign(turn_i) changes > 3 times per 6 points and role != technical_noise: add instability_penalty

context does NOT mutate final layout directly context owner metric → Compo 1.05 receives signal → generate/re-generate local rhythm candidate → local rhythm metrics recomputed → candidate returned to global solver → global solver accepts / rejects / requests another pass
