# Documentation Index

This folder tracks project decisions, experiments, and evolving ideas.

- `decisions.md`: design/architecture changes and rationales
- `experiments.md`: experiment runs and results
- `ideas.md`: future ideas and hypotheses

Conventions:
- Append new entries instead of overwriting old ones.
- Record exact config file and key overrides when possible.
- Keep metrics in the order: avg_ks / avg_jsd / avg_lag1_diff.

Tools:
- `example/diagnose_ks.py` for per-feature KS + CDF plots.
- `example/run_all_full.py` for one-command full pipeline + diagnostics.
Notes:
- If `use_quantile_transform` is enabled, run `prepare_data.py` with `full_stats: true` to build quantile tables.

Current status (high level):
- Two-stage pipeline (GRU trend + diffusion residuals).
- Quantile transform + post-hoc calibration enabled for continuous features.
- Latest metrics (2026-01-27 21:22): avg_ks ~0.405 / avg_jsd ~0.038 / avg_lag1_diff ~0.145.
