+
+## Task
+
+Create `/docs/implementation-plans/property-model-foundation-implementation-plan.md`.
+
+The plan must define the runtime property model contract:
+
+- `Property` is the base class for element properties and sections.
+- `PropertyKind` identifies concrete property families; phase 1 supports only `Shell`.
+- `ShellProperty` derives from `Property`.
+- `Domain` owns property objects through RAII.
+- `Domain` validates duplicate property ids and missing material ids.
+- `Element::propertyId()` remains an id reference; elements do not own property objects.
+
+Keep out of scope:
+
+- shell section stiffness;
+- material constitutive matrices;
+- shear correction;
+- element formulation;
+- assembly, solver, HDF5 output, and reference comparison.
+
+## Tests To Write First
+
+- Documentation-only step. No C++ test is required in this step.
+
+## Acceptance Criteria
+
+```powershell
+python -m unittest discover -s scripts -p "test_*.py"
+```
+
+## Verification Notes
+
+1. Confirm the plan does not change MITC4 formulation or tolerance policy.
+2. Confirm the plan keeps solver state out of `Domain`.
+3. Update `phases/property-model-foundation/index.json` for this step result.
