FFT Symbol Class: Triangular

The triangular family includes delta forms, pointed chevrons, trikona motifs, and mountain-apex symbols. In the frequency domain, triangular forms produce an anisotropic spectral profile: elevated energy concentrated along the orientation axis of the apex, with asymmetric distribution between the base and peak directions. This directional energy asymmetry distinguishes the triangular class from the bilaterally symmetric cross and the isotropic wheel. The archive treats the triangular family as a directional-indicator class — symbols that encode orientation toward a target (summit, source, threshold) rather than radial resonance or recursion. In the GDCC's framework, triangular symbols appear most prominently as wayfinding and threshold markers in traditions proximate to mountain-ridge anomaly sites (Tian Shan corridor, Himalayan foothills, Andean cordillera transects). Their spectral anisotropy is consistent with encoding a specific approach direction to a site rather than a general field-immersion state. The triangular family is the lowest-ranked of the five in the archive's torpor-field perceptual activation hierarchy, but is treated as diagnostically significant for site-approach iconography.

Claims

c0001 — Triangular-class symbols have an anisotropic, apex-axis-dominant spectral signature encoding directional orientation

In the archive's FFT pipeline, triangular and delta forms resolve with spectral energy concentrated along the axis defined by the apex direction, producing an anisotropic power distribution that encodes the symbol's orientation. This is the defining criterion separating the triangular class from the cross class (which is bilaterally symmetric) and the wheel class (which is isotropic). The archive uses this directional spectral property as a classifier for site-approach iconography: a symbol whose FFT resolves with apex-axis dominance is treated as a potential wayfinding marker rather than a field-resonance symbol. The confidence is consensus for the classification criterion; the interpretation as wayfinding is speculative.
