| Name | CXCAD2 |
| Title | CXCA.D2 — Cervical Cancer Screening Eligibility |
| Description | Logical model for the inputs and output of the cervical cancer screening eligibility decision (D2). Paired with the QCXCAD2 Questionnaire for data capture and consumed by the CXCAD2DTScreeningEligibilityLogic CQL library. Reflects the binding eligibility rules in Mongolia MOH Order A/641 (2020) section 2.2. Note: the LogicalModel ID is `CXCAD2` (no period) because periods in LogicalModel IDs collide with FSH path generation; the human-readable title preserves the `CXCA.D2` notation. |

  CXCAD2 | C | 0..* | Base | CXCA.D2 — Cervical Cancer Screening Eligibility Constraints: cxca-d2-screen-date-not-future |
  clientAge | 1..1 | integer | Client's age in years on the encounter date | |
