| 4 | **Статус:** stub hub (2026-05-31) — developmental math / numeracy evidence, **не** CASA spec. |

| 6 | ## Scope |
| 7 | |
| 8 | - Детское развитие **числа и вычисления** (basic calculation, number sense, achievement). |
| 9 | - **Не** путать с `math.numerics-pde` (PDE/численные схемы). |
| 10 | - **Не** путать с `cognition.language-acquisition` (L1); cross-link только где общие когнитивные факторы (oral language, WM). |

| 21 | Human numeracy evidence → **deny** прямой import в F0/bench без engineering bridge. См. `Financial/software/open/casa-ontology-payload/design/` (F0, bukvar phases) — гипотезы only. |
