STR.13:4.4 - Preserve a repertoire that supports the next use

For each retained entry, make the problem, first useful result, method or candidate status, situation conditions, serious alternative and retention reason easy to recover. Keep the evidence and its limits attached to the exact semantics, performers, support and window they concern.

Where derivation matters, ME.15 preserves the relationship between variants and the separate descriptions and support editions. Where a downstream use needs an explicit set result, use G.5’s applicable selection or declaration contribution. A declaration of an already selected set does not repeat the choice, admit its members or commission their use.

An existing working note, example, searchable discussion or method description may preserve all that is needed. Create a new card, diagram or archive only when it improves an actual retrieval or reuse problem enough to warrant maintenance.

Make retirement precise. Removing an entry from current offered choices need not erase its history or an adequate use elsewhere. State the conditions under which it should be reconsidered, not a universal expiry date.
