Add the `screen` entrypoint (parallel ~10-wide, cached weights) and run a 24-drug pilot vs HDAC2 (+Zn), ranked by Boltz-2 P(binder). ~$1.3. Result (recovery test at scale): top 9 are ALL HDAC inhibitors (trichostatin-A/vorinostat/panobinostat/belinostat/scriptaid/mocetinostat/ entinostat/apicidin >=0.99; valproic-acid 0.91), clean drop-off to hydroxyurea 0.78 and non-HDAC drugs to dexamethasone 0.03. Captures the structure-activity gradient (hydroxamates > weak fatty-acid > non-HDAC). Honest false negative: romidepsin (potent HDAC inhibitor) ranks low (0.43) -- it's a depsipeptide PRODRUG co-folding doesn't model. Screen mishandles non-standard chemotypes. Screening pipeline validated; next is the full 300-drug discovery run. max_containers=10 (parallel safe once weights cached). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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
