PSD.14:4.6 - Return only the affected decision-support consequence

Trace the changed premise into the particular claim or disposition that relies on it. Preserve inspected independent results for their current conditions. If dependence or coverage remains unresolved, state that gap; do not label an uninspected branch unaffected.

Current returnWhen it is warrantedWhat happens next
Unchanged within stated conditionsQualified evidence does not alter the relied-on premise, or the changed claim is outside the inspected use.Retain that bounded advice and its current conditions. State the next observation only when an actual follow-up use needs it. This is not authority to continue an intervention.
NarrowedA useful portion still has an adequate basis, but the previous scope, configuration, window or strength is no longer supported.Return the surviving claim and the withdrawn scope explicitly. Do not relabel the narrowed result as the original whole.
Blocked for the affected useA necessary premise, authority condition, observation or interpretation is unavailable or no longer adequate.State what cannot responsibly be advised or relied on now, the missing basis and the receiver who can resolve or reroute it. Preserve separate usable content.
Reopen a named contributorA needed stronger answer warrants an obtainable source, candidate, value, uncertainty, model, consequence, robustness or scope result, considering the complete acquisition burden.Request that bounded result through its direct owner. The present qualified limit can close the earlier answer; a pending request is not the refreshed result.
Compose a later recommendationChanged qualified premises require a different disposition or a newly composed answer to the receiving question.Use PSD.13 with the current premises and remaining gaps. Preserve the earlier recommendation occurrence and the separate later choice.

These are scoped conclusions, not a universal status system or a five-step lifecycle. One event can leave an internal-development claim unchanged, narrow a mixed-arrangement claim to configuration A, block advice about B, and reopen its evaluation supplier. Only the affected combined recommendation needs recomposition.

Keep continue, adjust, refresh and reframe precise. Continuing reliance on unchanged advice is a decision-support return. Adjusting a selected action requires the competent owner and its authorized decision, even if the original formulation remains adequate. Refreshing a model or evidence invokes its supplier and does not itself change action. Reframing reopens the problem or boundary through PSD.3 or PSD.4 when the old question no longer covers the material situation.

For one known reliance question, use A.10 and the direct subject guidance. If a changed source requires discovering and revalidating several actual receiving uses, use A.10.1 for its bounded search, coverage, direct-reliance test and subject-result return. That discovery preserves actual dependence and material gaps; equivalent irrelevant mentions can be grouped. The direct decision-support answer can finish without an additional common account unless a receiver needs that overview. Any no-impact claim still requires adequate coverage and support. Citation or adjacency is not dependence. Use G.11 for currentness, decay and scoped refresh planning/reporting when that is the live result; neither pattern supplies a new domain conclusion or recipient choice.
