  "summary": "The API keeps SKU/EAN uniqueness, identifies the conflicting field from the database constraint, and the UI prevents duplicate in-flight saves while presenting actionable conflict feedback.",
  "evidence": [
    "Existing 409 uniqueness behavior is preserved",
    "SKU and EAN constraint names map to field-specific domain messages",
    "Enter plus blur is guarded by a per-field in-flight key",
