Validation demo · question.v1

This demo is only about “structured output vs content” — no engine details.

✅ Positive case · metal-green pass

Valid question JSON (good_single_choice.json: schema / stem / 4 options / answer / explanation complete)

→ Metal-green pass · status=active

🟡 Negative case · quarantined for review

Missing stem / bad options (structural defects like bad_missing_schema.json)

→ Quarantined 🟡 · status=pending_review

Note: every AI output must pass validation; structural defects are quarantined for review, never silently dropped.
