E.21:4.5.1 - Consume Pattern-Edition Use-Value Evidence Noncompensatorily
When an E.19:4.3.3 replay is current, use that one stable-candidate replay as evidence for the E.21 assessment. During assessment, keep materially affected predecessor and candidate-only uses distinguishable whenever their action, result, boundary, necessity, or consequence can differ; do not copy clean per-use dispositions into the E.21 result. The evaluator still applies every existing coordinate required by the declared scope once. The result names the replay loci in EvaluationEvidenceBasis and carries only distinctions, failures, or improvements that actually change a coordinate rationale or PatternQualityStatus; it does not replace the coordinate set with one use-value score, average replay results, or infer a coordinate value from an E.19 outcome.
Apply these consequences:
| Use-review condition | Mandatory E.21 consequence |
|---|---|
A required prior-edition use probe is regressed | Set status to repairBeforeUse. Every affected coordinate is at most 2 partiallyExpressedForDeclaredUse. Include at least PatternApplicationGuidance and PracticalUseDeltaAndHarmPrevention when action or result was lost; also include each of ClosureAndBoundedNonUseRecoverability, NeighborAuthorityAndBoundedUseFit, UseAffordabilityAndApparatusProportionality, and ClaimJustificationTraceabilityCurrentnessAndReplayability when that coordinate’s claim depended on the use. |
| A completed required new intended-use check establishes insufficient support for the candidate-only use | Set status to repairBeforeUse. Every affected coordinate is at most 2. Include at least PatternApplicationGuidance and PracticalUseDeltaAndHarmPrevention. Additionally cap each of EntityOfConcernPrimacyAndSemioBiasResistance, ClosureAndBoundedNonUseRecoverability, NeighborAuthorityAndBoundedUseFit, UseAffordabilityAndApparatusProportionality, CaseCountercaseAndTransferCoverage, and ClaimJustificationTraceabilityCurrentnessAndReplayability only when the established insufficiency affects that coordinate’s claim. |
| A required new intended-use check is unperformed or its basis is unavailable | Leave the dependent values unestablished and the complete evaluation in draft form under §4.3. Name the missing check and withhold the admissible-use conclusion; preserve supported values elsewhere. A missing check does not establish that the candidate cannot perform the use. |
| An optional new intended-use check is absent or insufficient for the candidate-only use | Do not create a status blocker merely from absent optional breadth. The missing case cannot support a breadth, transfer, or value-5 claim. Reflect the absence in CaseCountercaseAndTransferCoverage and every coordinate whose declared scope actually includes that use. |
| A new intended-use check is adequate for the candidate-only use | No blocker follows from that check. Its evidence may support affected existing coordinates but establishes neither their values nor status by itself. |
The pattern’s subject, problem, action, and result are not stated in usable positive terms: its own EntityOfConcern, first useful move, practitioner action, practical delta, or next useful action cannot be recovered | Set status to repairBeforeUse. PatternApplicationGuidance, EntityOfConcernPrimacyAndSemioBiasResistance, PracticalUseDeltaAndHarmPrevention, and UseAffordabilityAndApparatusProportionality are each at most 2. |
| A required enumeration has an unresolved hidden kind, alien member, hidden proposition, false closure claim, or series whose form contributes nothing to the receiving use | Set status to repairBeforeUse. SemanticKindAndNameRecoverability is at most 2; each of EntityOfConcernAndClaimScopeStability, NeighborAuthorityAndBoundedUseFit, FormalClaimAdmissibilityAndLensFit, and PatternApplicationGuidance is also at most 2 when the unresolved or needless series affects that coordinate’s claim. |
A required prior-edition use is discoverably transferred | No regression blocker follows. The handoff evidence may support NeighborAuthorityAndBoundedUseFit, PatternApplicationGuidance, and ClosureAndBoundedNonUseRecoverability but establishes none of their values by itself. |
A harmful or false prior-edition use is intentionally retired with a positive corrected action or boundary | No regression blocker follows. Evaluate the corrected use and harm prevention on their own evidence. |
| The material-change trigger is false | Apply no new use-review cap. The ordinary complete coordinate, rationale, and result requirements still apply whenever an E.21 result claim is requested. |
The cap is 2, not 3, because 3 sufficientlyExpressedForDeclaredUse already means usable for the declared scope while the required action or semantic member here is unusable. Unrelated strengths, source count, formal cleanliness, or corpus projection cannot compensate for the failed required use. Conversely, preserved, improved, transferred, intentionally retired, or adequate candidate-only evidence can support only the existing coordinates whose claims it actually tests; it cannot raise unrelated coordinates or determine status by label.
