  "summary": "You can build exactly what was requested and still miss what was needed.",
  "kind": "question",
  "body": "Separate two questions. Verification asks whether the result meets the specified requirements. Validation asks whether it supports the intended use under relevant conditions. Keep evidence for both; passing a technical acceptance test cannot repair a requirement that describes the wrong outcome.",
  "limits": [
    "A happy demonstration is not sufficient validation either. Include relevant constraints and exceptions without treating a small sample as every possible use."

  "example": "An export contains every required column, but its users cannot identify rejected records. Format conformance passed; the operational need remains unresolved.",
  "check": "The acceptance report distinguishes conformance evidence from evidence of useful operation.",
  "question": "Which requirement does this test verify? · Which real user task and operating conditions does validation represent? · What would reveal that the specification was satisfied but the job still failed?",
