Manufactured Rank Is a Spectator: A Causal Test of Nonlinear Low-Rank Adapters in Task Adaptation — data artifact

Slim, reusable data artifact for the paper "Manufactured Rank Is a Spectator: A Causal Test of Nonlinear Low-Rank Adapters in Task Adaptation."

Contents (CSV + JSON; see ARTIFACT_README.md):rca_eta.csv / rca_interventions.json — per-checkpoint retained-gain fraction (eta) and raw scores for the Rank-Content Ablation interventions (truncate-to-nominal-rank, matched-energy random removal, tail-only, tail-spectrum placebo).

mora_rca_control.json — RCA positive control on MoRA (genuine linear high rank).

memorize_runs.csv / memorize_results.json — the rank-demanding memorization sweep: recall, stable/numerical rank, and fold depth |omega*BA| across frequency.

runs.csv — per-run training scores with stable/entropy-rank summaries across the GLUE (DeBERTaV3-base) and commonsense (Llama-3.2-1B QLoRA) tiers.
