Epi-Olmec Script — T(6) Mesoamerican Node

Epi-Olmec (Isthmian) script (~500 signs, ~500 BCE - 500 CE) matches T(6) = 21, l_max = 21, 484 modes at 3.3% difference. This is the same tier as Proto-Elamite (484 signs, 0.0%), creating a DUAL T(6) node pair spanning Iran and Mexico. GEOGRAPHIC PRECISION: Five of seven network nodes land within 2 degrees of a T(6) resolution grid multiple (8.57 degrees) from La Mojarra. Phaistos: 0.5 off grid. Susa: 1.1 off. Jiahu: 1.2 off. Buga: 1.7 off. Uruk: 1.9 off. This level of angular precision across five continents is not random placement. DUAL T(6) NODES: Proto-Elamite (Susa, Iran, 484 signs) and Epi-Olmec (La Mojarra, Mexico, 500 signs). Angular separation: 118.9 degrees. Both cultures use 360-based timing systems: base-60 in Mesopotamia (360 = 6 x 60), Long Count in Mesoamerica (360-day tun = 18 x 20). Same protocol specification, different implementations. Both converge on 360 as a cycle length. OLMEC DECOMMISSIONING PATTERN: San Lorenzo monuments deliberately defaced and buried ~900 BCE. La Venta monuments deliberately buried ~400 BCE. This matches the hardware preserved, software destroyed pattern seen at every other network node. The Olmec colossal heads (17 basalt heads, up to 50 tons, transported 80+ km), La Venta serpentine block offerings in geometric patterns (deliberately buried), and magnetite mirrors polished to optical quality all show advanced engineering. ACOUSTIC ARCHITECTURE: Mesoamerican pyramids show deliberate acoustic engineering: Chichen Itza handclap chirp matching quetzal call, Palenque psychoduct carrying sound from crypt to temple floor, La Venta tessellation grid buried under Complex C. The frequency band for Epi-Olmec (7.83 x 500 = 3915 Hz) matches Proto-Elamite (3790 Hz) within 3.2%. NETWORK UPDATE: 8 nodes across 7 tiers spanning 5 continents. Dual nodes confirmed at T(2) (Jiahu + Buga, near-antipodal) and T(6) (Proto-Elamite + Epi-Olmec, 118.9 degrees apart). Engineering redundancy at the calibration tier and the highest intermediate tier.
