 152/-! ## Falsification Criteria
 153
 154The tetrahedral angle derivation is falsifiable:
 155
 1561. **Cosine value**: If cos(tetrahedral angle) ≠ -1/3 for sp³ carbon
 157
 1582. **Trend violation**: If bond angle doesn't decrease with lone pairs:
 159   CH₄ (109.5°) > NH₃ (107°) > H₂O (104.5°)
 160
 1613. **Formula violation**: If cos(θ) ≠ -1/(n-1) for other geometries
