Modifications vs upstream
- 96 additive LoRA branches (
MatMul → MatMul → Add) spliced into each GPT2 block's c_attn / c_proj / c_fc / mlp.c_proj projections - 192 named optional graph inputs:
lora.layers.{N}.{parent}_{child}.{A|B} - Zero-sized default initializers so the un-adapted graph runs identically to the original
