How much theory must be reconstructed for a first use? Adapt van Oostrum, Langer and Ay (2025), Introduction and §§1–2, 4: connect the operational question to stated model variables and inference, work an example, and recover deeper derivations when they are needed. The alternative is to use an interpreted supplied implementation. Retain that cheaper route when it suffices; reconstruct dependencies when adaptation or explanation requires them. Sections :4.1–:4.4 make that choice explicit. The source provides a discrete active-inference account and a minimal implementation, not evidence that one learning sequence suits every practice or agent.

How can notation reveal what an application still lacks? Adapt SICM’s Preface: recover function arguments, substitutions and composition where implicit conventions obscure the operation. A familiar conventional expression is cheaper when the reader can already use it reliably. Sections :4.2–:4.4 therefore call for operative reconstruction at the unresolved step; :5.2 supplies a case. The selected contribution is explicit operation recovery. Its source’s strong requirement of automatic interpretability is appropriate for computational exposition; ordinary use may be settled by a clear hand-worked construction.

What does a theory’s formal structure contribute to an application? Adopt Baez and Stay, §2.3’s constructive comparison of cartesian and monoidal operations. A familiar “parallel composition” description can leave input duplication unresolved. Section :5.1 obtains the required operation or the obstruction under stated rules, then asks whether the receiving practice can supply it. This pays the cost of recovering only the consequential structure. The broader cross-disciplinary correspondences in that paper do not establish the physical copying operation in our case.

The common method is a synthesis of these contributions. Reopen it when a better approach obtains a usable application with less reconstruction, when a recurring failure requires another connecting operation, or when changed tools alter the contribution the receiver must understand.
