3. Separate observed differentiation, causal support, and today’s decision
The twenty-release window records eight reopened releases. Six of those eight had a late supplier-pinout/integration-bundle mismatch before rig reservation. The rig was available in seven of the eight reopened releases; two rig-outage cases elsewhere in the window completed under the same procedure when backup capacity appeared. Two earlier comparable quarterly-cadence releases reconciled the same versioned input before their safety boards and did not reopen.
DA-EC417-CadenceDifferentiation-1 retains a partial descriptive account of the counts and timing/co-occurrences above. This application does not supply the dated source editions, variant appearances, selection decisions, and diagnostic rival comparison needed to complete the differentiation history. Keep that reconstruction gap; these observations neither complete ME.19’s historical result, choose B2, nor identify a causal effect. ME.19:5.1 supplies a filled constructed signoff history to show that separate operation, not evidence about EC-417.
The receiving causal-use question is CUQ-EC417-CadenceEffect-1: would entering provisional-evidence reconciliation at D-21, rather than waiting for signed evidence at D-8, reduce mismatch-related reopenings in EC-417-like releases for this team, supplier, and change class? CUR-EC417-CadenceEffect-1 records causalUseClaimKind = causalEffectClaim and target rung interventionalActionRung.
Its actual components are:
evidencePathRefs = [EP-EC417-BundleSequence-20, EP-EC417-RigAvailability-20, EP-EC417-QuarterlyCadence-2];empiricalDataRegimeRefs = [EDR-EC417-NaturalReleaseHistory];- no identification result and no estimate result;
- common threat screen
CTS-EC417-CadenceEffect-1, withcausalUseQuestionRef = CUQ-EC417-CadenceEffect-1.
The threat screen keeps intervention consistency, confounding/exchangeability, overlap, interference, missingness/selection, measurement, and target transport as live threats; temporal ordering alone is clear. routedThreatRefs = []: no specialist result closes a live threat. The C.28 verdict is therefore unsupported.
No positive interventional causal reliance is supported. The observed timing and co-occurrence remain in separate non-causal result DC-EC417-CadenceMismatch-1 as a trial hypothesis and design constraint. Unsupported uses include the claims that cadence mismatch caused the reopenings or that B2 will reduce them. Reopen only when a governed comparison or replayable identification/bound result varies reconciliation timing while rig availability, approver capacity, outcome definition, and evidence access are controlled or explicitly modeled.
Today’s architecture decision remains separate. AD-EC417-B2-Trial-1 may consume the non-causal mismatch result, capacity calculation, the covering trace/safety/release assignments, PERM-TraceAcceptReject-17, the two independently supported direct authority relations, and reversibility to choose a bounded trial. It may not consume the unsupported causal-use result as positive evidence.
