Base-256 digits of Catalan's constant G = Σ(−1)ⁿ/(2n+1)². Irrationality and transcendence both unproven; normality unknown.
Standard analysis sees: rich, high-entropy values; aperiodic / broadband; high-complexity (noise-like); monofractal; high-dimensional / space-filling. The atlas detects no named structure beyond this.
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
