X-RLVR is an interpretability study and tooling for comparing a base language model with an RLVR-trained model on text reversal. The main workflow takes prompts, loads both models, computes attention, attribution, saliency and logit-lens results, summarizes metrics, and writes comparison visualizations. The README also documents SFT followed by RL training through PRIME-RL; this repository provides a CLI wrapper and configuration files rather than the trainer implementation. Edges reflect the sampled analysis CLI and documented training handoff; training internals are external.
