IS.Reference:9 - Reconsider only the contribution whose basis has changed

Use the following differences to locate a needed return:

Changed basis	Contribution to reconsider
The recipient’s wanted result, authority or service terms change.	The IS.1 undertaking and any dependent support strategy.
A formerly sufficient explanation no longer distinguishes action-changing cases.	The IS.2 diagnosis and its subject or research supplier.
A provider, tool, source, permission, workload or relevant recipient condition changes.	IS.3 provision and adaptation; A.15.8.MS, HCD or OCE where the needed contribution belongs.
Later work contradicts a target, strategy, fit or causal claim.	A.3.1.MI’s exact maintained claim and the professional return that can revise it.
Continued use depends on help that is ending or on a new receiving setting.	The IS.5 continuation, transfer or extension.
Better implementation-support knowledge changes the explanation or useful operation.	The affected helping Method and its examples, source bounds and related returns.
A relied-on FPF or DPF meaning changes.	The affected dependency and the IS instructions that consume it, before relying on unchanged wording.

Do not infer a framework-wide failure from one local exception, or preserve every existing sentence merely because a case succeeded. Recover which claim has lost its basis and what current contribution would repair the receiving use. Reuse unaffected knowledge and qualified results. Where the change exposes a larger development question, return it at that scope.
