A.11.OP:4.2 - Compare keeping and removing through three branches
| Admission branch | Passing condition | Boundary of the result |
|---|---|---|
| Decision-changing result | At least one materially plausible result changes a named subject branch or selection among named alternatives inside the horizon. An information-gathering action passes when one of its possible results changes a later policy even if the immediate action stays the same. | The passing basis is the result-to-decision dependency. Obtainability, expected contribution after uncertainty, burden and eventual choice remain open. |
| Selected realization | The action performs a required part of an already selected transformation or obtains the required subject result. A deterministic step needs no fabricated rival outcomes. | This branch establishes the action’s contribution to the selected result; it presupposes selection and leaves feasibility, authorization, actual Work, and result status to their direct owners. |
| Assurance or recoverability preservation | Removing the action changes a named assurance or recoverability condition on which the declared use relies. | This branch preserves that condition; its required level and evidential basis come from the direct assurance or recovery owner. |
Compare the concrete situation with and without the requirement. A passing branch removes the objection that the work contributes nothing. Retain it only as far as its direct basis justifies requiring it. An already selected transformation or established reliance can supply that basis without another comparison.
When a proposed inquiry could matter but its worth remains open, apply C.11.DUA to the actual demand and receiving question. Identify the attainable observation, what it could change, and its whole cost within the receiving horizon. Compare available continuations through C.11 when a local choice is needed. A useful possible result can still arrive too late, require unavailable means, or cost more than its contribution. Keep the presently supported answer or select a feasible alternative under its actual limits. Do not invent an OptionSet or an inquiry merely to certify that none is needed.
If no branch passes, remove the requirement or leave it as an optional convenience. Convenience and prior investment do not supply the missing receiving difference.
