logicalExp(tag, left, right) lets a producer label a source or native &&, || or ?? case while constructing a canonical conditional graph. It delegates the choice to the shared source FAST sugar and constructs the graph through fromFast.

The operands enter once as external binding identities. Their existing graph objects remain the condition, retained operand or selected right value, so selection preserves identity and keeps the right operand conditional. The bridge accepts well-formed graph operands, including invocation fragments; the consuming boundary retains its ordinary admission responsibilities.

The labels describe source syntax. Canonical graph data contains ?: and strict comparisons, with no logical operator tags. The bridge is a producer convenience rather than an importer for former graph documents.
