SYSE.4:4.5 - Update the engineering-assurance account

After evidence is available, reuse a sufficient engineering-assurance account. Otherwise update or write the account so that the practitioner can recover:

1. the named target claim and decision question;
2. the actual challenge Work and its direct result;
3. the descriptive A.10 evidence/provenance path and currentness basis;
4. the result’s configuration, condition, scale, uncertainty, and applicability limits;
5. the practical change in reliance for this decision; and
6. the smaller earlier answer, specialist question, or next challenge affected by that change.

The account remains a C.2.1 episteme about the named target claim. Its ClaimGraph adds claims about performed Work, direct results, evidence use, changed reliance, and the affected earlier answer. Those named participants do not become a composite EntityOfConcern.

State the reliance change in ordinary language, using a conclusion that fits the case: for example, the claim remains usable for the decision within the stated limits; the practitioner must narrow reliance; the practitioner must replace or withdraw the claim for this use; or available evidence leaves the question unresolved. When the current question is an assurance claim or material reliance threshold, use B.3 for the named assurance-result claim or no-assurance disposition. The engineering-assurance account cites that result; it does not replace it.

When the result is unresolved, identify the missing input that limits this answer—for example, a configuration, comparator, observation window, calibration, causal link, specialist criterion, or independent challenge. Return to the inquiry choice in §4.2 before planning further Work. A narrower supported answer or a justified stop can complete the current question. Missing information establishes neither the target claim nor its negation.
