# 3D Euler-Bernoulli Beam UEL RED Test Report

## Metadata
- feature_id: uel-3d-euler-beam
- source_reference_models: `docs/reference-models/uel-3d-euler-beam.md`
- status: red-evidence-recorded
- owner_agent: implementation-agent
- date: 2026-06-11

## Scope

This report records the step 6 RED evidence after adding no-Abaqus Fortran tests and `tests/fortran/manifest.json`.

Production Fortran source was not added in this step. The expected RED condition is a compile failure from missing planned production source:

- `src/fortran/uel_3d_euler_beam_kernel.f90`
- `src/fortran/uel_3d_euler_beam_abi_adapter.f90`

## Test Files Added Before Production Code

| manifest_test | source file |
| --- | --- |
| `uel_3d_euler_beam_kernel_stiffness` | `tests/fortran/uel_3d_euler_beam/test_kernel_stiffness.f90` |
| `uel_3d_euler_beam_kernel_transform_modes` | `tests/fortran/uel_3d_euler_beam/test_kernel_transform_modes.f90` |
| `uel_3d_euler_beam_abi_static` | `tests/fortran/uel_3d_euler_beam/test_abi_static.f90` |
| `uel_3d_euler_beam_invalid_inputs` | `tests/fortran/uel_3d_euler_beam/test_invalid_inputs.f90` |
| shared support | `tests/fortran/uel_3d_euler_beam/test_support.f90` |

## Command Log Summary

| order | command | exit_code | result | evidence |
| --- | --- | --- | --- | --- |
| 1 | `python -m json.tool tests/fortran/manifest.json` | 0 | pass | manifest JSON parsed successfully |
| 2 | `python -m unittest discover -s scripts -p "test_*.py"` | 0 | pass | 56 Python harness tests passed |
| 3 | `python scripts/validate_reference_artifacts.py` | 0 | pass | reference artifact metadata validation succeeded |
| 4 | `python scripts/validate_fortran.py` | 1 | environment failure before RED | current `cmd.exe` child process sees empty `%PATH%`; nested `cmd` command is not found |
| 5 | `$env:PATH='C:\Windows\System32;C:\Windows;C:\Users\user\miniforge3'; C:\Users\user\miniforge3\python.exe scripts/validate_fortran.py` | 1 | expected RED | `ifx` reached compile and failed because `src/fortran/uel_3d_euler_beam_kernel.f90` does not exist |
| 6 | `python scripts/validate_workspace.py` | 1 | environment failure before RED | reference validation passed, then Fortran validation hit the same nested `cmd` lookup issue |
| 7 | `$env:PATH='C:\Windows\System32;C:\Windows;C:\Users\user\miniforge3'; C:\Users\user\miniforge3\python.exe scripts/validate_workspace.py` | 1 | expected RED | reference validation passed, then Fortran validation failed on missing production kernel source |
| 8 | `$env:HARNESS_FORTRAN_VALIDATION='detect'; python scripts/validate_workspace.py` | 0 | pass | reference validation passed; Fortran manifest/compiler detection mode produced no compile commands |

## RED Failure Classification

- classification: `fortran-compile`
- first implementation-owned failure after environment normalization: missing planned production source
- primary evidence tail:

```text
xfortcom: Severe: No such file or directory
... file is 'C:\git\AbaqusSubroutineDev\src\fortran\uel_3d_euler_beam_kernel.f90'
compilation aborted for C:\git\AbaqusSubroutineDev\src\fortran\uel_3d_euler_beam_kernel.f90 (code 1)
```

The subsequent module import errors in `test_kernel_stiffness.f90` are secondary to the missing kernel module source.

## Environment Note

This Codex process can find `cmd.exe` from PowerShell and Python, but a child `cmd.exe` invoked during `validate_fortran.py` sees an empty `%PATH%` unless a minimal `PATH` is set explicitly. The normalized command above confirms that Intel oneAPI `ifx` is available through the configured oneAPI env script and that the actionable RED failure is the missing production source, not a missing compiler.

## Handoff to Step 7

Implement the minimum production Fortran needed to turn the four manifest tests GREEN:

- `src/fortran/uel_3d_euler_beam_kernel.f90`
- `src/fortran/uel_3d_euler_beam_abi_adapter.f90`

The Abaqus fixed-form `UEL` wrapper remains planned for the implementation gate but is not required to satisfy these no-Abaqus RED tests unless the step 7 plan explicitly includes it.
