E.4.CM:4.7 - Expose a short entry and keep the explanation usable

A practical-use card or long mantra can remind a reader how to use one composite Method or several connected Methods. It should lead to their developed public explanation. E.11 selects when that entry is useful. A card that only helps choose among methods can remain navigation.

Discover useful combinations from recurring situations as well as from already named patterns. Follow a result that readers repeatedly struggle to use, or a connection they repeatedly invent. Compare the methods, rules and worked constructions supplied by independently developed patterns and earlier treatments. Reuse a complete available construction; where none exists, develop the missing joins through §§4.1–4.6. A combination need not have been assembled in one source before the author can construct it. Conversely, co-occurrence in a source or a long list of relevant patterns does not establish a useful combination.

Do not require every public Method to have a separate card. Start from a recognition problem that changes use. The short form may omit detail available at the direct destination; it must retain the conditions that determine the first move and an honest stop.

When a supplier or receiving condition changes, return to the affected connection and encompassing uses. Separate permitted Method variation from a different Method with A.3.1 when that question matters. B.1.5.RS governs replacing a constituent; E.19 governs a corresponding pattern-edition change. Retain the explanation’s useful conditions even when a shorter public form is desired.
