- Decompress the choice.
Review the actual artifact revision. Record purpose, alternatives, rationale provenance, assumptions and tradeoffs without inventing creator intent.
- Model only what matters.
When engineering deepening applies, externalize the relevant truth, ownership, state, boundary, contract, failure and time/ordering surfaces. Give consequential assumptions their own evidence and revisit lifecycle instead of burying them in rationale.
- Challenge the model.
Name a bounded condition that could disconfirm the choice or assumption. If it is assessed, label the evidence as walkthrough, implemented or runtime-tested. Do not replace missing evidence with a familiar best practice.
- Prove at the declared stage.
Keep specified, walkthrough, implemented and runtime-tested evidence separate and bound checks to the exact decision context.
- Make the next human decision.
Accept, revise or keep the choice pending. Name the owner, smallest coherent next step and revisit trigger.
A separate structure view is optional review guidance, not an extra gate. Keep it separate from the proposed study design.
