# IPSAS and FQBM — Gaps and Missing

Short summary of **remaining gaps** and **FQBM/Matrix status**. Full scope: [IPSAS_COMPLIANCE.md](IPSAS_COMPLIANCE.md). Suggestions: [RECOMMENDATIONS.md](RECOMMENDATIONS.md).

---

## 1. IPSAS: Summary by status

| Status | Count | Notes |
|--------|--------|--------|
| **Supported** | 1 | IPSAS 1 (statement of financial position: structure, current/non-current). |
| **Structure** | 20+ | Templates in `fqbm.ipsas.presentation`: 3, 5, 9, 10, 14, 19, 20, 23, 24 (+ budget_actual_from_state), 29/30/41, 38, 46, 47, 48, cash basis, RPG 2, functional/presentation currency. |
| **Partial** | 6 | CF (no revenue/expense); 2 (no activity classification); 4 (S, pass-through only); 6, 22, 28, 34, 35 (sectoral/consolidated layout only); 15 (maturity_risk_disclosure_structure); RPG 1 (r−g in sovereign module). |
| **Missing / N/A** | 25+ | Not applicable to monetary/financial core: 7, 8, 11–13, 16–18, 21, 25–27, 31–33, 36–37, 39–45, 49–50, RPG 3, SRS 1. 26: no impairment model. |

**Main gaps for entity-level IPSAS:** Cash flow by activity (IPSAS 2); FX translation of FC positions and gain/loss disclosure (4); measurement basis and ECL (41); full consolidation rules (6, 35). Budget data is external; use `budget_actual_from_state(state, budget)` for actuals.

## 2. FQBM / Matrix: What’s implemented

- **State:** L_cb, cbdc_liability, reporting_date, functional_currency, presentation_currency. **Open economy:** `open_economy_view(A_dom, A_ext, L_dom, L_ext, E)`.
- **Matrix:** `four_quadrant_matrix()`, `four_quadrant_summary()`, `cross_sector_consistency_check()`.
- **Parts VII–IX, XI:** Shadow banking (repo_multiplier in dashboard, margin_spiral_simulation); CCP (ccp_params, result["ccp"]); CBDC (cbdc_liability in state and IPSAS); scenarios + `get_case_narrative()`.
- **IPSAS layer:** Statement of financial position (CB, bank, consolidated), budget vs actual (template + budget_actual_from_state), cash flow from Δstate, comparative, notes, maturity/risk, FX translate, and all structure templates above.

## 3. Remaining gaps (concise)

| Area | Gap |
|------|-----|
| **Part VIII** | Full clearing balance sheet not modeled (margin/waterfall only). |
| **IPSAS 2** | No operating/investing/financing classification of cash flows. |
| **IPSAS 4** | No translation of FC assets/liabilities or FX gain/loss in performance statement. |
| **IPSAS 41 / 46** | No measurement basis or ECL model; use templates + user data. |
| **RPG 1** | Full long-term sustainability disclosure not implemented. |
| **GGS** | Sectoral structure only; boundary and entity list set by jurisdiction. |
