Scientific glossaryBiochemical Precursor Node (X30)Origin: Yolia's safe educational catalogExact route: /biblioteca?ruta=glosario/x30_cbga_precursor_node FULL TOPICBiochemical Precursor Node (X30) Easy explanation It's the central checkpoint: it checks whether all the X30's previous tools have already given the green light before considering the precursor pathway the plant uses to build its compounds. It never measures or promises a percentage of resin acids — it only monitors the biological pathway. Medium explanation It only moves forward if there is no critical risk in the case and if the previous tools (glandular phase, flow, balance, integrity) have already passed. It is a convergence node, not a standalone tool. Advanced explanation It blocks with CRITICAL_RISK if the case's risk level is critical, or with NOT_SECRETORY_PHASE if the glandular phase is not yet secretory. It is deliberately conservative: by design, it never calculates or exposes a resin acid percentage — that is an explicit product decision, not a technical limitation.
