Each part appears **once**; relations (composed_of, typical_scale, translates_from, translates_to) connect them into a relational net. The Material layer and the unified chain script reference this index and the Scale registry. --- ## Parts and relations | Part | composed_of | typical_scale | translates_from | translates_to | |:---|:---|:---|:---|:---| | **[[Planck]]** | — | Planck length | — | [[Quark]] | | **[[Quark]]** | — | Planck / strong | [[Planck]] | [[Hadron]] | | **[[Hadron]]** | [[Quark]] | nuclear / fm | [[Quark]] | [[Atom]] | | **[[Atom]]** | [[Hadron]] (nucleus), electron | [[Scale registry\|Atomic]] (Bohr) | [[Hadron]] | [[Molecule]] | | **[[Molecule]]** | [[Atom]] | [[Scale registry\|Molecular]] | [[Atom]] | [[Cell]] (or Unit cell) | | **[[Cell]]** | [[Molecule]] | μm | [[Molecule]] | [[Organism]] | | **[[Organism]]** | [[Cell]] | m | [[Cell]] | — | | **[[Unit cell]]** (optional) | [[Atom]], [[Molecule]] | nm–μm | [[Molecule]] | — | Translation rule: see **[[../../expanded theory applied/further applications/Material layer/Material layer (RST)#V. Layer-to-layer translation|Material layer (RST) §V]]**. The engine builds the scale registry by scanning part notes for a ` ```scale_part ` block (L in meters). **To add a new part** (e.g. Quantum): add a note here and a `scale_part` block; the JSON is generated when the engine runs. --- ## Links - **Scale registry:** [[Scale registry]] (typical L per scale; scripts mirror this). - **Material layer:** [[../../expanded theory applied/further applications/Material layer/Material layer (RST)]] - **RST:** [[../Relational Substrate Theory (RST)]]
