AES-256-CTR ciphertext of structured data --- the gold standard for pseudorandom streams, indistinguishable from random without the key
Standard analysis sees: rich, high-entropy values; aperiodic / broadband; high-complexity (noise-like); high-dimensional / space-filling. The atlas detects no named structure beyond this. It sits beside Golden Ratio Digits in the atlas (standard-bank rank 20) — a neighbor conventional features miss.
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
