#
# Automated search across 5 GNN architectures and hyperparameters
# for predicting Ruby method complexity from AST structure.
#
# Launch:
# ratiocinator research specs/gnn_complexity.yaml
#
# The dataset (22K Ruby methods) is in the repo branch.
# No external data staging needed.
# What to research
topic: "Comparing GNN architectures (GCN, SAGE, GAT, GIN, GraphConv) for predicting Ruby code complexity from Abstract Syntax Trees. The baseline uses GraphSAGE with hidden_dim=64, 3 layers, achieving MAE 4.77 on 22K Ruby methods."
