inter-stem-validation

Apply the strict seven-step sequence: identify assemblages, relations, tensions, concentration, condition modification, transformation, and possible propagation. The decisive test is whether the crossing modifies the conditions under which the assemblages function, not whether two domains are connected.

An ordinary node concentrates relations and tensions within one assemblage or territory. An inter-stem node crosses assemblage boundaries and changes the conditions under which those assemblages function. Every inter-stem node is a relational concentration, but not every concentration is inter-stem.

No. A title or interdisciplinary theme is insufficient. The analysis must reconstruct a transformation, such as representation becoming intervention, showing how relations between AI and biological assemblages change the conditions of biological design or experimentation.

No. Propagation is possible but not mandatory. A candidate can be a strong inter-stem node without a demonstrated propagation pathway, but any claimed propagation must be independently supported with evidence of what transforms and where it moves.

False positives include classifying a candidate merely because two domains are mentioned, AI is applied to another field, the topic is socially important, or the section has a plus sign in its title. Connection and interdisciplinarity alone never establish inter-stem status.

Reject it when the concentration remains within one assemblage, when no condition of functioning changes, or when evidence only supports a cross-assemblage connection without transformation. Asymmetric, mediated, or contingent transformations should not be rejected merely for lacking a simple causal chain.
