output.directory after download. For Nova Blueprint, open
score_report.json before choosing a new strategy: it records explicit
validity, molecule count, miner execution, and the target-versus-antitarget
decomposition that identifies whether acquisition, selectivity, validity, or
runtime is the actual bottleneck. When available,
molecule_diagnostics.jsonl identifies weak submitted molecules and
antitarget liabilities; structured [nova_diag] lines in miner stdout expose
candidate throughput and validity-gate rejection counts.
