+
+## Overview
+
+**BULMA** (**B**iologically-informed **U**nified **L**earning for **M**ulti-stress **A**tlas) is a reproducible computational framework that integrates:
+
+1. **Predictive Atlas** — Two-tower MLP predicting ABC transporter–compound interactions using ESM-2 protein embeddings + ChemBERTa ligand embeddings  
+2. **Causal Ranking** — Doubly-robust DR-Learner (EconML) estimating causal treatment effects per transporter across stress conditions  
+3. **Active Learning** — Uncertainty / Diversity / Hybrid strategies to maximize discovery efficiency  
+4. **Stress Transfer** — Generalization from ethanol→oxidative→osmotic conditions
+
+**Key findings:**
+- Maps interactions between 28 ABC transporters × 260 compounds under 3 stress conditions
+- Identifies ATM1, MDL1 as top stress-consistent effectors (SIMS score)
+- Active learning achieves ≥1.2× label-efficiency over random acquisition
+- 47 causal stress–transporter relationships separated from 83 spurious correlations

+## Data
+
+All processed data is available on this Hugging Face dataset page.
+
+| File | Description | Rows |
+|------|-------------|------|
+| `data/processed/protein.csv` | ESM-2 embeddings (1280-dim) for 28–38 ABC transporters | 28–38 |
+| `data/processed/ligand.csv` | ChemBERTa embeddings (768-dim) for 260 compounds | 260 |
+| `data/processed/labels.csv` | Binary interaction labels with provenance (assay, condition, replicate) | ~9,360 |
+| `data/processed/causal_table.csv` | Expression + covariate table for DR-Learner | 6,000 |
+
+**Protein sequences** were fetched from UniProt (taxon 559292) for canonical ABC transporters. Compounds were drawn from a curated library of alcohols, aromatics, and heterocycles.
+
+---
+
+## Reproducing Results
+
+### Step 1 — Install dependencies
+
+```bash
+pip install -r requirements.txt
+```
+
+### Step 2 — Compute embeddings (or use precomputed)
+
+```bash
+python scripts/compute_embeddings_protein.py   # ESM-2, ~10 min on GPU
+python scripts/compute_embeddings_compound.py  # ChemBERTa, ~5 min
+```
+
+### Step 3 — Run the full pipeline
+
+```bash
+# Section 2: Atlas training + evaluation
+python scripts/run_pipeline.py --task atlas --cfg env/config.yaml
+
+# Section 3: Causal ranking
+python scripts/run_pipeline.py --task causal \
+    --causal_csv_in data/processed/causal_table.csv \
+    --causal_out results/causal_effects.csv
+
+# Section 4: Active learning
+python scripts/run_pipeline.py --task al --cfg env/config.yaml
+```
+
+### Step 4 — Notebook (recommended)
+
+Open `notebooks/BULMA_full_pipeline.ipynb` — every cell is self-contained and runs top-to-bottom.
+
+---
+
+## Reproducibility
+
+- Global seed: `17` (set via `utils.io.set_seed`)
+- All splits are deterministic (GroupKFold, cold-transporter, cold-ligand, cold-both)
+- A `results/env_manifest.json` is written at runtime capturing library versions
+- `USE_MOCK = True` generates synthetic data so the notebook runs without external files

+
+### Protein sequences
+Sourced from UniProt (organism taxon 559292, *S. cerevisiae* S288C).  
+Embedded with `facebook/esm2_t33_650M_UR50D` (mean-pooled over sequence positions).
+
+### Compound library
+Curated library of 260 compounds: linear/branched alcohols (C1–C20),
+substituted aromatics, heterocycles, and 2 experimental controls (ethanol, H₂O₂).  
+Embedded with `seyonec/ChemBERTa-77M-MTR` (CLS token).
+
+### Known causal signals (injected in mock data)
+- **ATM1**: protective effect (+0.08 ATE on growth outcome)
+- **SNQ2**: sensitizing effect (−0.05 ATE on growth outcome)
+
+These are used for validation in Section 3 and Section 6.

+# BULMA — Results
+
+This directory contains all numeric results produced by the BULMA pipeline.
+Every file here was generated from the notebook `notebooks/BULMA_full_pipeline.ipynb`
+running on a Colab T4 GPU with real ESM-2 and ChemBERTa embeddings.
+
+## Files
+
+### Core results
+
+| File | Section | Description |
+|------|---------|-------------|
+| `causal_effects.csv` | §3 | Causal ATE per transporter (30 genes), with 95% CI from 300-bootstrap + overlap trimming. Sorted by ATE descending. |
+| `al_gains.csv` | §4 | Mean label-efficiency gain vs random baseline for each AL strategy, with bootstrap CI. |
+| `ct_map_top_drivers.csv` | §3/§5 | Top 10 transporters by mean absolute ATE across stress conditions. |
+| `sims_scores.csv` | §5 | Stress-Invariant Mechanism Score (SIMS) = \|mean CATE\| / SD across stresses. |
+| `anchor_per_stress_ates.csv` | §6.1 | Per-stress ATEs for 4 landmark transporters (ATM1, PDR5, SNQ2, YOR1). |
+
+### Metadata
+
+| File | Description |
+|------|-------------|
+| `atlas_summary.json` | Dataset dimensions and list of split regimes / models evaluated in §2. |

+make_mock_data.py — Generate synthetic processed data for offline testing.
+
+This script creates realistic-looking (but entirely synthetic) versions of
+the four processed CSV files, so the full pipeline can be run without
+internet access, GPU, or real experimental data.
+
+Outputs
+-------
+data/processed/protein.csv       28 transporters × 1280-dim ESM-2 embeddings (mock)
+data/processed/ligand.csv        260 compounds × 768-dim ChemBERTa embeddings (mock)
+data/processed/labels.csv        ~9360 interaction labels with provenance columns
+data/processed/causal_table.csv  6000 samples × expression + covariate columns

+    # ABC-Atlas: Prediction, Causal Ranking, and Active Learning for Yeast ABC Transporters
+
+    **Pipeline:** *Atlas (Section 2) → Causal (Section 3) → Active Learning (Section 4) → Stress Transfer (Section 5) → Validation (Section 6).*
+
+    This package reproduces the full analysis and assembles figures/tables for submission.
+
+    ---
+
+    ## 🚀 Quick Start
+    ```bash
+    pip install -r requirements.txt
+    # Re-generate figures and tables (Sections 2–7):
+    jupyter nbconvert --to notebook --execute notebooks/main.ipynb
+    ```
+
+    Outputs are written to `results/` and tracked in `package/figure_map.csv`.
+
+    ---
+
+    ## 📌 Headline Results (auto-filled)
+    - **Section 2 – Atlas:** AUPRC **{auprc}**, AUROC **{auroc}** under cold splits.
+    - **Section 3 – Causal ranking:** top resilience drivers include **{top_causal}**.
+    - **Section 4 – Active learning:** mean efficiency gain over random **{gain}**.
+    - **Section 5 – Stress transfer:** train on ethanol → measurable generalization to oxidative/osmotic.
+    - **Section 6 – Validation:** literature cross-check concordant for **PDR5, YOR1, ATM1**; SNQ2 shows context-dependent sign.
+
+    See `results/claims_table.csv` for full numeric statements and CIs.

+
+    ---
+
+    ## 📂 Data (processed)
+    - `data/processed/protein.csv` – 30–38 ABC transporters (ESM-2 embeddings)
+    - `data/processed/ligand.csv` – ~600 compounds (ChemBERTa embeddings + provenance)
+    - `data/processed/labels.csv` – ~8–9k protein×ligand binary interactions with assay provenance
+    - `data/processed/causal_table.csv` – ~6k stress/regulator outcomes for causal estimation
+
+    ---
+
+    ## 🔁 Reproducibility
+    - Seeds, splits, and estimator configs saved in `results/*snapshot*.json`.
+    - `package/figure_map.csv` contains MD5 checksums for every artifact in `results/`.
+    - Environment pins in `requirements.txt` (lock exact versions on request).
+
+    ---
+
+    ## ⚖️ Limitations
+    Ligand diversity (~600) is narrower than industrial libraries; causal signs can be stress-specific; transfer is preliminary; wet-lab validation is recommended.
