A08

• Input: A framework-like artifact, evidence, uses, failures, and constraints.
• Operation: Sequence characterization, comparison, minimal redesign, implementation test, and reassessment while carrying trace links forward.
• Output: Tested, versioned redesign with decision history.
• Scope conditions: Artifacts that are inspectable, modifiable, and testable.
• Failure conditions: A stage is skipped; evidence links break; comparison baseline is weak; tests are not prospective.
• Predicted effect: The bundle may reduce late rework beyond the sum of individual stages.
• Measurement: Rework time, defect escape, and interaction contrast in a factorial study.
• Implementation test: Independently execute all stages from frozen inputs.
• Decision rights: Stage owners propose; artifact owner accepts.
• Uncertainty handling: Unresolved findings carry forward.
• Verification: Stage gates and final outcome test.
• Provenance: End-to-end lineage.
• Implementation cost: Highest of the candidate set.
• Limitations: No explicit interaction form or directional factorial contrast exists; therefore H2 audit fails. Direct: sequence. Inference: possible interaction.
