이전 Step 전제

Step 0이 app-level path/log request fields를 만들었고 기존 linear invocation이 <stem>_results.h5를 사용한다.

Domain stores procedure identity and raw four *STATIC values only. Factor sequence is derived in Step 5. PRESELECT output requests are warning no-ops and do not create Domain, Analysis, or HDF5 state.

RED

Add tests first.

NSNR-IO-001: *STEP, NLGEOM=YES maps to StaticProcedureKind::kNonlinearFullNewton.
NSNR-IO-002: *STEP, NLGEOM=NO maps to kLinearSmallDisplacement and existing shell linear tests keep passing.
NSNR-IO-003: missing NLGEOM keeps current linear behavior.
NSNR-IO-004: nonlinear *STATIC requires four finite positive values and time period exactly 1.0.
NSNR-IO-005: raw values are preserved in StepDefinition without derived factor list.
NSNR-IO-006: unsupported nonlinear procedure or mixed linear/nonlinear steps fail closed with unsupported-analysis-procedure.
NSNR-IO-007: S4 and S4R shell definitions remain approved nonlinear semantic inputs.
NSNR-IO-008: mixed B33/S4 nonlinear model fails with unsupported-mixed-element-model.
NSNR-IO-009: *OUTPUT, FIELD, VARIABLE=PRESELECT is accepted with deterministic warning and no Domain state.
NSNR-IO-010: *OUTPUT, HISTORY, VARIABLE=PRESELECT is accepted with deterministic warning and no Domain state.
NSNR-IO-011: malformed PRESELECT parameters fail as input errors.

Run:

cmake --build .harness/build --config Debug
ctest --test-dir .harness/build -C Debug -R "Domain|DomainMapping|Abaqus" --output-on-failure

Expected: new tests fail. Unexpected pass stops the Step.

GREEN

Extend StaticStepDefinition and StepDefinition exactly with the fields and accessors above.
Update domain construction so source-order boundaries and loads remain deterministic.
Update domain_mapping_context to parse NLGEOM=YES, preserve raw *STATIC, emit PRESELECT warnings, and keep PRESELECT out of Domain state.
Preserve existing linear shell and beam mappings.

상태 기록

Only Step 1 status and one-line summary/error/blocked payload may be updated by the Implementation Agent. Executor owns timestamps, commits, retry, and next Step selection.

금지사항

Do not add LoadFactorSequence() to Domain. 이유: factor sequence ownership belongs to Step 5 control.
Do not store PRESELECT flags in Domain or HDF5 state. 이유: approved I/O contract makes PRESELECT an ignored warning no-op.
Do not alter requirements or I/O docs. 이유: upstream contracts are approved.
