- Add centering support to MemoryBank (center_query, apply_centering, mean
persistence in save/load) to remove centroid attractor in Hopfield dynamics
- Add center flag to MemoryBankConfig, device field to PipelineConfig
- Grid search scripts: initial (β≤8), residual, high-β, and centered grids
with dedup-based LLM caching (89-91% call savings)
- Energy landscape visualization: 2D contour, 1D profile, UMAP, PCA heatmap
comparing centered vs uncentered dynamics
- Experiment log (note.md) documenting 4 rounds of results and root cause
analysis of centroid attractor problem
- Key finding: β_critical ≈ 37.6 for centered memory; best configs beat
FAISS baseline by +3-4% F1
