Module decision 

Decision pattern storage and CITL trainer module

This module provides:

• PatternStore: Stores and retrieves decision patterns using cosine similarity search
• CitlTrainer: Correlation-Informed Transfer Learning for error-fix prediction

GH-28: DecisionPatternStore

Stores DecisionPattern instances with feature-weight vectors and supports nearest-neighbor retrieval via cosine similarity.

GH-29: DecisionCITL trainer

Trains a simple linear correlation model from ErrorFixPair samples, then predicts fix feature vectors from error feature vectors.

Structs

CitlTrainer

CITL trainer that learns a linear mapping from error features to fix features.

DecisionPattern

A decision pattern with feature weights and metadata.

ErrorFixPair

An error-fix training pair for CITL.

PatternStore

Store for decision patterns with cosine-similarity retrieval.
