R2 Pre-Lock Evidence Snapshot · 2026-05-22 KST
Every axis, on the record.
9-axis GOLD filter applied to 977,415 in silico compounds. Each axis is a live JSON evidence file. We publish negative results (MolFormer LoRA, TYK2 RBFE NaN) alongside positive ones because honest disclosure is a load-bearing scientific claim, not a footnote.
Status — in silico, pre-wet-lab. Every candidate below is a computational prediction. Wet-lab validation (R1 biochemical assay · 5/15–6/15 window) is pending; measured hit-rate and kinase selectivity will be published on this page on arrival. Until then, reported metrics are predictive, not assay-confirmed.

Section 5 · Boltz-2 cofold breakdown
27 compounds · 4 targets · 5-seed ensemble
Each compound co-folded with its target protein 5 times. Mean confidence per row is averaged across all 5 model seeds. CDK4 confidence 0.93 = pocket-aligned binding; TNIK 0.41 reflects novel chemotype outside training distribution (not an affinity signal — pocket fit only).

Section 8 · Honest disclosure
Three things that did not work
Cherry-picking positives is the failure mode of AI drug discovery. Below are three negative results we encountered today, published as evidence in their own JSON files.
_phase_a2_molformer_lora.json
MolFormer-XL LoRA (r=16) multi-task
R 0.565 (5-target mean)
Foundation model + LoRA fine-tune underperforms per-target Morgan+RF baseline (R 0.671). Multi-task interference confirmed: TYK2 0.487, TNIK 0.437, CDK4 0.463, CDK6 0.538, EGFR 0.807. Frozen + Morgan concat closes gap (R 0.666) for n>2000 targets only.
→ Classical feature engineering wins at our dataset scale.
_phase_c_tyk2_rbfe_failure.json
TYK2 RBFE OpenFE 1.7 quickrun
FAILED — NaN
SimulationNaNError: Propagating replica 0 at state 0 resulted in a NaN! · Started from X-ray PDB 4GIH (pdbfixer cleaned, 4841 atoms). NaN persists even with crystal protein — not a Boltz cofold pose issue, fundamental force field or alchemical topology problem.
→ TYK2 ABFE-grade ΔΔG unavailable. R2 falls back to Vina + GNINA + AEV + Boltz.
_phase_e_selectivity_v2.json
Saturn pool selectivity (Kinome v2)
0 / 1000 selective
Median on-vs-off-target diff is OOD-negative (−0.28). Saturn-novel chemotypes lie outside ChEMBL active distribution → unreliable selectivity prediction. 73 compounds show any positive diff, 0 show > 1.0 log unit advantage.
→ R2 CRO biochemical panel (≥20 kinases) required for selectivity anchor. In parallel, a KLIFS-anchored kinome-wide selectivity model is on the roadmap (P1-6) to bring off-target prediction in-distribution for novel chemotypes.
