Implementation Scope

Post-step ABI correction note: the original step 7 implementation deliberately deferred the fixed-form Abaqus UEL wrapper. The follow-up correction report docs/corrections/uel-3d-euler-beam-uel-abi-correction.md supersedes that deferred-wrapper status and records the added wrapper, NSVARS>=1 policy, and LFLAGS(1)/(4) checks.

Production source added in this step:

src/fortran/uel_3d_euler_beam_kernel.f90
src/fortran/uel_3d_euler_beam_abi_adapter.f90

The implementation covers the approved no-Abaqus scope:

12-by-12 Euler-Bernoulli local stiffness matrix.
Local frame construction from node coordinates and PROPS(7:9).
K_global = T^T*k_local*T.
Static residual RHS(1:12,1) = -K_global*U(1:12).
AMATRX and RHS selection for LFLAGS(3)=1, 2, and 5.
Shape, property, geometry, orientation, and unsupported-request diagnostics.
Deterministic zeroing of RHS, AMATRX, and ENERGY; PNEWDT unchanged for valid calls.

The fixed-form Abaqus UEL wrapper remains deferred because the approved step 7 no-Abaqus tests target the kernel and ABI adapter only.

Harness Support Changes

Two validation harness fixes were required after the step 6 RED manifest became executable:

scripts/validate_fortran.py now creates each build/fortran-tests/<test-name>/ directory before invoking Intel Fortran.
scripts/fortran_toolchain.py now invokes the oneAPI environment script through ComSpec or discovered cmd.exe and sets a minimal Windows PATH for the child command shell.

These changes are covered by updated Python harness tests in:

scripts/test_validate_fortran.py
scripts/test_fortran_toolchain.py

Command Log Summary

order	command	exit_code	result	evidence
1	`python scripts/test_validate_fortran.py -k build_commands_create`	1 then 0	RED then GREEN	failed before build-dir creation fix; passed after `build_dir.mkdir(...)`
2	`python scripts/test_fortran_toolchain.py -k wrap_command`	1 then 0	RED then GREEN	failed before absolute `cmd.exe` and minimal PATH wrapper; passed after wrapper update
3	`python -m unittest discover -s scripts -p "test_*.py"`	0	pass	57 Python harness tests passed
4	`python scripts/validate_reference_artifacts.py`	0	pass	reference artifact metadata validation succeeded
5	`python scripts/validate_fortran.py`	0	pass	all six no-Abaqus Fortran manifest executables compiled and passed with Intel `ifx` through oneAPI env script
6	`python scripts/validate_workspace.py`	0	pass	reference validation and Fortran validation both succeeded

No-Abaqus Fortran Tests Passed

manifest_test	result
`uel_3d_euler_beam_kernel_stiffness`	pass
`uel_3d_euler_beam_kernel_transform_modes`	pass
`uel_3d_euler_beam_abi_static`	pass

Handoff to Step 8

Step 8 can proceed to validation readiness using the passing no-Abaqus evidence above. External Abaqus reference artifacts remain absent and must still be user-generated before solver-result comparison.
