PSD.15:4.6 - Return a small current repertoire with differentiated dispositions

Decide what the practice can now offer, for which use and with which limits. Useful dispositions include retaining an established offering; narrowing its applicability; adding a separately identified variant for a qualified use; retaining a proposal for a bounded trial; requesting missing evidence; and withdrawing an offering from one use while preserving its history.

Keep identification separate from validation. An independently identified Method may still have unproved practical fit. A candidate account may have useful trial evidence without yet resolving its Method identity. State both rather than using one maturity label for every question.

For each action-changing entry, make the following recoverable in the simplest form that serves its next user.

Repertoire positionContent needed for use
Recurring situation and receiving resultWho uses the offering, what difficulty it addresses, which result it provides, and the conditions that matter.
Method or candidateExact reusable action and status; entry, joins, allowed variation and stop; where the full description can be obtained.
Comparative reasonIncumbent or serious alternative, the gained capability or repaired failure, and the accepted effort or other loss.
Evidence and source basisClaim-sized sources and relevant trials, their configurations and limits, defeating evidence and the next unresolved question.
LineageThe actual source way or candidate, preserved and changed semantics, and the evidence for derivation; cultural links only where established.
Current offeringWhat is available for this use, conditional, retained for trial, narrowed or withdrawn; required performer/support conditions and source responsibility.
Refresh and exitWhich changed claim, failed condition or receiving need would reopen this entry, and what remains usable elsewhere.

A repertoire may retain alternatives without ranking them. When the actual question is declaring a selector-facing set result over already identified members, use G.5 with the exact members, outcome, ordering and basis it requires. Distinguish alternatives retained for later choice from members all included in one named joint use. A Method-family registry or selector declaration supplies neither field fit nor actual enactment and need not be rebuilt for every repertoire update.

Make the next use easy to find: which Method a practitioner should inspect for the named situation, which claim still needs evidence, or which use has been withdrawn. A large source map that gives none of these is not the promised repertoire.
