Signed-delta preparation for B2

Under B2, the supplier-configuration role prepares the comparison of the signed supplier pinout received for closure with the exact provisional pinout edition used in D-21 integration. Retain both edition identifiers and the provisional uncertainty and use history; identify the changes, and use schema correspondence A-17 to locate the affected integration-bundle fields. SafetyReviewer-17 checks that comparison and identifies the affected traceability and verification checks for the safety board. The preparation result is a version-linked pinout-difference record with the affected checks, not a B-versus-B2 allocation decision or a release authorization. The assumed preparation burden remains 1.60 h supplier plus 0.40 h safety; performing affected verification, deciding safety closure, and any integration rework remain separate. Missing signed evidence invokes R as described in section 8.

ME.6 keeps several structures distinct:

  • Method relations: the four identified Methods are co-used; every composition/order relation for C-EC-Release-v2 remains proposed;
  • Work relations: A is signed-first; B/B2 are provisional-first then signed reconciliation; each B2 branch that uses AI suggestions contains bounded human Work set W-TraceAcceptReject-17 with one accept/reject occurrence per used suggestion; R can occur only after B2 entry, retains already-performed Work, and repeats that trace-review Work for every repeated AI suggestion;
  • allocation: B overloads the safety engineer, while B2 transfers 1.60 h and stays within the peak bound; admitted Systems TraceReviewer-17, SafetyReviewer-17, and ReleaseDecider-17, their three covering assignments, trace permission PERM-TraceAcceptReject-17, and the two direct authority relations remain separate;
  • subject/support/permission/authority: the three decision Systems and their Work remain distinct from their assignments, the trace permission, and the two direct authority relations; supplier configuration, PLM, test rig, and AI provider retain separate responsibility/access/support relations;
  • description correspondence: checklist order corresponds only partially to Work overlap and branch stops;
  • cultural relation: retention of a weekly-integration practice remains a later cultural-continuation question.

AD-EC417-B2-Trial-1 selects only a prospective three-release B2 trial under ASG-TraceReview-17, ASG-SafetyReview-17, ASG-ReleaseDecision-17, PERM-TraceAcceptReject-17, AUTH-SafetyEvidence-17, AUTH-ReleaseDecision-17, capacity, confidentiality, evidence, and reversibility conditions. It consumes DC-EC417-CadenceMismatch-1 as a non-causal rationale and treats the causal-use verdict as unsupported. A remains a pre-entry alternative. R is a post-entry recovery and can never become a retrospective A occurrence. No obtaining ArchitectureRelation or methodPartOf fact is asserted.
