To prevent dead-end sequences from entering the synthesis pipeline, computational hits must pass through quantitative triage filters before chemical synthesis begins.

Synthesizability screening combines historical flow-synthesis traces with physical chemistry rules. Two key metrics quantify aggregation risk:
