What happens at a boundary?
Conversion, coupling, self-production, and individuation
Compare four accounts of boundaries without collapsing their different questions.

A signal changes form
Start with Beer's organisational account. A boundary transducer converts what crosses between domains. Ask which distinctions can survive, and whether the receiving side can register and act on them.
Interaction changes the participants
Maturana's account adds the history of structural change through recurrent interaction while the organisation defining each unity is conserved. A perturbation triggers a change whose form depends on the recipient's structure. This comparison is editorial; it does not assert a Beer–Maturana lineage.
The unity produces its boundary
In the biological account, a network produces components that regenerate the network and constitute its unity. A boundary is part of this production. The term requires more than endurance, a feedback loop, or a metaphor of organisational life.
Read the conditions before extending the analogy
Varela, Maturana, and Uribe's 1974 paper offers a definition, an illustrative model, and a six-point identification key. The final questions concern whether boundary and other components participate in the network of production.

An individual takes form
Simondon asks how individuation proceeds. In his crystallisation example, each structured region enables further structuring. This use of transduction concerns the formation of individuals and relations, not just translation between already constituted domains. The sequence is a comparison of questions, not a genealogy.
