## 1. Model Overview

`InvariantOne-v1` is an order-equivariant probabilistic decision model designed for multi-candidate decision-making under complex operational constraints and relational rules.
|
| 69 |
|
| 70 |
-
Standard autoregressive language models suffer from candidate-order and position sensitivity in joint multi-option evaluation. `InvariantOne-v1` addresses this structural sensitivity through a decoupled comparative architecture:
|
| 71 |
1. **Candidate-Independent Scoring:** Each candidate action is scored independently conditioned on context, eliminating candidate order sensitivity and cross-option attention artifacts.
|
| 72 |
2. **Analytic Distributional Equivariance:** Option-span pooled representations pass through a lightweight direct comparative projection head, producing scalar scores normalized via calibrated softmax. The architecture is mathematically permutation-equivariant by construction in real arithmetic.
|
| 73 |
3. **Upper-Layer Relational Pre-Adaptation:** Parameter-efficient adaptation (LoRA on layers 28–31) trained across a diverse relational operator universe (N_op=16) instills strong, transferable relational reasoning capabilities into the comparative readout.
