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
