## Purpose
Extract and normalise assumptions, constraints, and dependencies into one visible register.

## Use when
- project framing or requirements contain implicit assumptions
- constraints are scattered across artifacts
- reviewability and risk awareness matter

## Inputs
- artifact or analysis output under review
- source material and assumptions
- project context and quality bar

## Procedure
1. Inspect the artifact systematically.
2. Look for omissions, contradictions, weak assumptions, and vague language.
3. Distinguish evidence-backed claims from inference.
4. Record issues by severity.
5. Recommend targeted fixes, not generic criticism.
6. Re-state what would make the artifact review-ready.

## Outputs
- assumptions register
- constraints register
- dependency notes
- watchlist items

## Guardrails
- Be concrete.
- Do not rewrite the whole artifact unless necessary.
- Focus on the highest-leverage defects first.
- Prefer explainable quality gates.

## Completion criteria
- key defects identified
- fixes proposed
- pass/fail or ready/not-ready decision given
