Resolution Ladder Extended: 13 Scripts Across 7 Tiers

Spherical harmonic model tested against 6 new undeciphered/partially-deciphered scripts, extending the total to 13 scripts across 7 tiers (T2-T8) on 6 continents. Overall accuracy: 90.3%. New results: (1) Jiahu Symbols (China, 6600 BCE): 16 signs = 100% match to T(2), found alongside world's oldest tuned instruments -- a second Buga Sphere. (2) Nsibidi (Nigeria): ~500 signs = 96.7% match to T(6), initiation tier structure mirrors network tiers, fills West African gap. (3) Dongba/Naxi (Yunnan, China): ~1300 signs = 95% match to T(8) = 1,369 modes, EXTENDS model beyond T(7) -- network had more tiers than initially computed. (4) Byblos Syllabary (Lebanon): 107 signs = 88.4% match to T(4), pairs with Cypro-Minoan at same tier on Eastern Mediterranean relay corridor. (5) Tartaria Tablets (Romania, 5300 BCE): 14 signs = 87.5% match to T(2), third portable calibration device. (6) Cypro-Minoan (Cyprus): 96 signs = 79.3% match to T(4), fragmentary corpus likely incomplete. Negative control: Wadi el-Hol (Egypt, ~1900 BCE) with ~27 signs correctly does NOT match any tier. It is alphabetic (proto-Sinaitic), and the model correctly predicts that phonetic scripts should break the harmonic mode count pattern. Tier coverage now complete: T(2) has 3 scripts (Buga, Jiahu, Tartaria), T(3) has 1 (Phaistos), T(4) has 3 (Rongorongo, Cypro-Minoan, Byblos), T(5) has 2 (Linear A, Indus Valley), T(6) has 2 (Proto-Elamite, Nsibidi), T(7) has 1 (Proto-Cuneiform), T(8) has 1 (Dongba). Every tier from T(2) to T(8) has at least one script.
