## 3. Canonical Longevity Vector Impacts (The 8 Longevity Pillars)
- **Bone Density & Connective Matrix**: **78/100** [Rank #32 of 142 in Bone Matrix] - Effect: Stimulates osteoblast mechanotransduction, tendon remodeling, and connective tissue collagen deposition
    - Mechanism: Axial mechanical loading and collagen peptides trigger Piezo1 mechanosensation and osteoblast extracellular matrix mineralization.
- **Cellular Longevity & Autophagy**: **82/100** [Rank #64 of 131 in Cellular] - Effect: Maintains genomic stability, telomeric integrity, extracellular collagen matrix, and mitochondrial proteostasis
    - Mechanism: Activates nuclear transcription factors (SIRT1/RAR), photobiomodulates cytochrome c oxidase, or enhances DNA strand break repair.
