docs/gpu_plan.md: cost-efficient plan for running AF3-class co-folding (Boltz-2/DiffDock) on a GPU then paying nothing when idle. - Key insight: structure-track data is tiny (MB of PDBs/SMILES); only the GPU + model weights are heavy -> serverless is ideal. - Recommend Modal (per-second billing, scales to zero = nothing to kill); RunPod as the SSH-box alternative with idle auto-terminate. - Lifecycle: image -> weights Volume (cache, don't re-download) -> run -> git push small results -> teardown automatic. - Phase 1 validate on 3 known binders (~$1) before paying for a screen; Boltz-2 (affinity) on an L4/A10 (24-48GB); est total ~$5-15. gpu/modal_app.py: Modal app skeleton (image, weights volume, GPU cofold() function, local entrypoint); boltz invocation stubbed with TODOs.

Reverso MVP — Sickle Cell Repurposing Pipeline
A minimum viable drug repurposing pipeline for sickle cell disease: build a disease signature from public transcriptomic data, build drug profiles for ~300 small molecules, and rank them by CMap-style connectivity scoring. Validated by a recovery test — do the two known sickle cell drugs (hydroxyurea, L-glutamine) rank near the top?
See PLAN.md for the full specification, locked decisions, and week-by-week build plan.
Quickstart
# Requires Python >=3.11,<3.13 (see note below)
pip install -e . # or: pip install -e ".[dev]" for test/lint tooling
pytest # run unit tests
Python version note: use Python 3.11–3.13 (
python3.13 -m venv .venv). Python 3.14 is not yet supported by all pipeline dependencies (pydeseq2,cmapPy).

The deliverable
When complete, the artifact to share is three files:
docs/recovery_test_report.md— the 2-page write-updata/results/ranked_candidates_v1.csv— the ranked drug list- The signature + drug profile files with provenance
