Divisor count d(n) --- erratic arithmetic function averaging ~ln(n), spikes at highly composite numbers, modulated by prime factorization structure
Standard analysis sees: heavy-tailed; right-skewed; anti-correlated (alternating); anti-persistent; blue spectrum (high-frequency power). 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.
