MATH.Preface:7 - Consequences, biases and limits

The language makes useful intermediate results available for reuse: composable paths, valid classes, interpreted expressions, witnesses, countermodels, invariant equations, solution families and qualified improvements. Their conditions help divide a larger problem among contributors and locate the part that needs revision.

This arrangement adds the cost of constructing the mathematical account. A reusable proof or operation can repay that cost across many cases. For a small question, direct calculation or an existing result can be more economical. A failed construction remains useful when it exposes the premise or operation that must change.

The examples favour small, inspectable constructions. They make dependence and failure visible, but do not establish that every larger instance will be computationally affordable. Existence of an answer, an efficient algorithm and an implementable calculation have different requirements.

The starting repertoire concentrates on formation, proof, representation and transformations. Numerical analysis, statistical inference, signal processing and specialized algorithm design supply substantial further methods. Use those contributions when the question reaches their conditions. The present patterns can help formulate that question and carry the resulting mathematical contribution into a larger argument.

An assisting agent can propose objects, examples or proofs and execute calculations. Its contribution must be understandable at the join where another contributor uses it. The mathematical statement and its justification remain available for criticism and revision, including when a person delegates the detailed calculation.
