What the Evidence Supports

Part V has supplied two different forms of evidence for MAGE.

The DocAble case provides depth. Its longitudinal record shows engineering structures emerging, changing, and sometimes being replaced under sustained implementation pressure. The case makes sequence and mechanism visible: missing representations can make global properties difficult to reason about; missing enforcement can leave consequential obligations dependent on repeated judgment; recurring failures can motivate durable changes to the environment; and explicit models can move from analytical aids into structures that participate directly in realization.

The industrial reconstructions provide breadth of realization. Systems developed independently under different constraints exhibit related moves: externalizing engineering knowledge, constraining delegated work, producing independent evidence, governing admission, and preserving useful judgment in structures later work can inherit. They also show that those moves need not share DocAble's architecture, terminology, or mechanisms.

The two forms of evidence have different limits. One deeply observed system cannot establish population-level effects or show that MAGE uniquely explains its development. Selected industrial accounts provide variation but less process history and do not constitute a representative sample. Neither view establishes that adopting MAGE causes greater productivity, quality, or safety.

What the evidence supports is narrower and sufficient for the next step: the constructs recur, the proposed mechanisms are plausible in practice, and their relationships are consequential enough to require explanation.

Part VI develops that explanation as a theory and asks what should follow if it is right.
