  threeLiveCharacteristicsAtMost:
    - characteristicRef: InterfaceStandardizationShare
      currentCue: controller ports are named by the same API family, but three field variants still require adapter-specific wiring.
      repairDirection: narrow the interface grammar and name the allowed variation before counting the interface as standardized.
      claimUseClass: local repair cue
      forbiddenOverread: the public API label is not substitutability or procurement suitability.
    - characteristicRef: SubstitutabilityWidth
      currentCue: two alternate controller boards pass the bench test, but only one has the required thermal envelope and connector constraints.
      repairDirection: state the substitution conditions and the exception before using the alternative count.
      claimUseClass: report-only proxy until C.16 or selection use is being made
      forbiddenOverread: the alternate-board count is not a selection result.
    - characteristicRef: EvidenceReuseShare
      currentCue: electrical-safety evidence is reused, while environmental evidence is recreated per enclosure variant.
      repairDirection: split reusable evidence package from variant-specific evidence and add source-return condition.
      claimUseClass: local repair cue with possible evidence-package use
      forbiddenOverread: reused evidence is not assurance sufficiency.
  observedProblem: the team says the platform is modular because interfaces are public and evidence is reusable, but field replacement and certification still create variant-specific work.
  relatedClaimPatternLocatorsIfClaimed: A.6.M for the module-interface relation; C.31.RSA if report-only share becomes reusable-structure accounting; A.10 or B.3 only if an exact evidence-use or assurance-use assertion is being made.
  stopCondition: stop at local repair until measurement basis, comparability basis, and any selection or assurance use are declared under their subject patterns.

Near miss: a high interface-standardization count alone is not a C.31 improvement. If field-service work, source-return events, or variant-specific evidence increase, the vector records that proxy divergence and returns to repair rather than treating the count as architecture quality.
