## Executive Overview

The **CrystalCall Solvent Triad** is a landmark ablation release investigating the interaction between continuous conversational language manifolds and discrete Abstract Syntax Tree (AST) tool-calling schemas within non-Euclidean hyperbolic space.

Standard function-calling models require billions of parameters to balance natural language instruction comprehension with rigid JSON syntax formatting. Through our **Crystallographic Dynamics Model (CDM)** architecture embedded in 7-layer Poincare geometry, we show that discrete AST schema routing can be achieved with ultra-high fidelity at sub-100M parameter scales.

This repository publishes the three core checkpoints of our continuous solvent ablation series:
- **`smt0`** (0% Solvent): Pure tool calling traces (APIGen-80k + Glaive-v2). All-time record validation compression: **0.2686 BPB** at step 92.5k.
- **`smt25`** (25% Eutectic Solvent): 75% tool traces mixed with 25% FineWeb-Edu conversational solvent. All-time multi-task frontier: **0.2893 BPB** with preserved conversational plasticity and superior argument extraction.
- **`smt50`** (50% Solvent): 50% tool traces mixed with 50% FineWeb-Edu conversational solvent: **0.4688 BPB** at step 75.0k. Demonstrates over-dilution of discrete tool attention boundaries.

## The 25% Eutectic Solvent Law

In non-Euclidean representation learning, discrete hierarchical data (such as JSON tool call grammars, parameter trees, and type signatures) naturally embed along the expanding boundary of negative curvature manifolds (Poincare ball H^d). 

However, our empirical runs revealed a fundamental representation hazard:
1. **The Singularity Collapse Hazard (0% Solvent)**: When training exclusively on structured tool traces (smt0), the model achieves rapid, low BPB (0.2686) on syntax tokens, but the hyperbolic manifold collapses into isolated, discrete boundary condensates. The continuous transitional manifold between user intent and tool triggering is starved of volume, leading to brittle instruction parsing.
2. **The Dilution Hazard (50% Solvent)**: Conversely, introducing too much conversational text (smt50) floods the negative curvature space with unstructured Euclidean-like language tokens. This dilutes the discrete Voronoi bisectors that partition specialized expert routing, degrading schema validity from 82.0% down to 62.0%.
3. **The Eutectic Optimum (25% Solvent)**: A precise 25% conversational solvent ratio provides the exact Riemannian volume required to keep the underlying manifold connected without diluting discrete expert crystallizations. Analogous to a eutectic alloy in metallurgy—where a specific mixture ratio yields the lowest melting point and densest crystalline grain—the 25% solvent ratio achieves the optimal Pareto frontier across schema compliance, argument accuracy, and natural language instruction parsing.
