+- **CI — Pre-migrated database template extended to all test suites**: The
+  `slow_integration_tests` and `e2e_tests` nox sessions now call
+  `_create_template_db()` and set `CLEVERAGENTS_TEMPLATE_DB` before running,
+  matching the fast-path DB copy already used by `unit_tests`, `integration_tests`,
+  and `coverage_report`. `slow_integration_tests` is also upgraded from `robot` to
+  `pabot` for parallel Robot Framework execution, consistent with `integration_tests`.
+  This eliminates redundant Alembic migrations across all test suites and reduces
+  total test suite wall-clock time. (#2334)

+## Domain Base Model
+
+**Module:** `cleveragents.domain.models.base`
+
+### `DomainBaseModel`
+
+```python
+from cleveragents.domain.models.base import DomainBaseModel
+
+class DomainBaseModel(BaseModel):
+    model_config = ConfigDict(
+        str_strip_whitespace=True,
+        validate_assignment=True,
+        arbitrary_types_allowed=False,
+        populate_by_name=True,
+        use_enum_values=True,
+    )
+```
+
+Shared Pydantic base class for all standard domain-layer models.  Inherit
+from `DomainBaseModel` instead of `pydantic.BaseModel` directly to get the
+canonical domain-layer configuration in one place.
+
+**Configuration semantics:**
+
+| Setting | Effect |
+|---------|--------|
+| `str_strip_whitespace` | Leading/trailing whitespace stripped from all `str` fields on assignment and validation |
+| `validate_assignment` | Field assignments after construction are validated like constructor arguments |
+| `arbitrary_types_allowed=False` | All field types must be Pydantic-compatible — keeps the domain layer clean |
+| `populate_by_name` | Models can be constructed using either the Python field name or the JSON alias |
+| `use_enum_values` | Enum fields are stored and serialised as their underlying primitive values |
+
+**Usage:**
+
+```python
+from cleveragents.domain.models.base import DomainBaseModel
+from pydantic import Field
+
+class MyDomainModel(DomainBaseModel):
+    name: str
+    count: int = Field(ge=0)
+```
+
+> **Note:** This class was introduced in v3.7.0 (PR #1941) to eliminate the
+> duplicated `model_config` that previously appeared in 14 separate domain
+> model files.  It is a pure structural refactor with no behavioral changes.
