 Sedlár (2016) designs and explores substructural epistemic logics under an informational interpretation with the explicit goal of attending to the Scandal of Deduction (SoD) from  section 1.1  above. The motivating idea here is that there are channels from one epistemic state of an agent to another epistemic state of that agent, and that certain epistemic actions (namely acts of reasoning) that facilitate information flow along such channels can be captured by the ternary relation \(R\) that marks channel application in  (13)  above. Punčochář and Sedlár (2017) introduce a substructural epistemic logic for pooling information in a group of agents via structured communication (viz. structured information flow) between them. In this context the binary combination operator \(\circ\) (‘\(\cdot\)’ in Sedlár and Punčochář’s notation) is a pooling operator between the different epistemic states of agents in a communicative group. The authors’ have several examples to suggest that both association and commutation are misguided in this context. Sedlár, Punčochář, and Tedder (2019) provide a semantics for universal and common knowledge operators via the now-familiar informational reading of the non-associative Lambek Calculus under an informational interpretation.
