## Current State

- Active objective: 3D Euler-Bernoulli beam Abaqus/Standard `UEL`
- Active phase: `phases/uel-3d-euler-beam`
- Active owner: unassigned
- Current status: completed ad hoc UEL ABI research correction note after step 7 implementation review
- Next action: correct the Abaqus-facing UEL wrapper/interface mismatch before executing `phases/uel-3d-euler-beam/step8.md` validation-readiness step

## Completed

  - Updated `phases/uel-3d-euler-beam/index.json` step 0 to `completed`.
- Completed step 1 research for `uel-3d-euler-beam`.
  - Created `docs/research/uel-3d-euler-beam-research.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 1 to `completed`.
- Completed step 2 formulation for `uel-3d-euler-beam`.
  - Created `docs/formulations/uel-3d-euler-beam.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 2 to `completed`.
- Completed step 3 numerical review for `uel-3d-euler-beam`.
  - Created `docs/numerical-reviews/uel-3d-euler-beam.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 3 to `completed`.
- Completed step 4 interface contract for `uel-3d-euler-beam`.
  - Created `docs/io-definitions/uel-3d-euler-beam.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 4 to `completed`.
- Completed step 5 test/reference model planning for `uel-3d-euler-beam`.
  - Created `docs/reference-models/uel-3d-euler-beam.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 5 to `completed`.
- Completed step 6 RED no-Abaqus test creation for `uel-3d-euler-beam`.
  - Created `tests/fortran/manifest.json`.
  - Created `tests/fortran/uel_3d_euler_beam/test_support.f90`.
  - Created `tests/fortran/uel_3d_euler_beam/test_kernel_stiffness.f90`.
  - Created `tests/fortran/uel_3d_euler_beam/test_kernel_transform_modes.f90`.
  - Created `tests/fortran/uel_3d_euler_beam/test_abi_static.f90`.
  - Created `tests/fortran/uel_3d_euler_beam/test_invalid_inputs.f90`.
  - Created `docs/build-test-reports/uel-3d-euler-beam-red.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 6 to `completed`.
- Completed step 7 Fortran implementation for `uel-3d-euler-beam`.
  - Created `src/fortran/uel_3d_euler_beam_kernel.f90`.
  - Created `src/fortran/uel_3d_euler_beam_abi_adapter.f90`.
  - Added source-smoke no-Abaqus tests under `tests/fortran/`.
  - Updated `tests/fortran/manifest.json` with the source-smoke tests.
  - Fixed `scripts/validate_fortran.py` to create per-test build directories.
  - Fixed `scripts/fortran_toolchain.py` to use `ComSpec`/absolute `cmd.exe` and a minimal Windows PATH for oneAPI env setup.
  - Created `docs/build-test-reports/uel-3d-euler-beam-green.md`.
  - Updated `phases/uel-3d-euler-beam/index.json` step 7 to `completed`.
- Completed ad hoc UEL ABI format research after user review feedback.
  - Created `docs/abaqus-uel-subroutines-research.md`.
  - Confirmed current source has no top-level Abaqus-callable `SUBROUTINE UEL(...)` wrapper under `src/fortran`.
  - Confirmed `uel3deb_abi_static` is a no-Abaqus adapter, not the manual Abaqus UEL ABI.
  - Identified a likely Abaqus input contract issue: documented `*USER ELEMENT, VARIABLES` must be greater than zero, so the current `NSVARS=0` / `VARIABLES=0` contract should be corrected before external Abaqus validation.

## In Progress

- None.

## Blocked

- None.

## Last Verification

Latest verification after creating the UEL ABI research document:

```bash
python -m unittest discover -s scripts -p "test_*.py"
python scripts/validate_workspace.py
git diff --check
```

Result: all passed.
- `python -m unittest discover -s scripts -p "test_*.py"`: 57 tests passed.
- `python scripts/validate_workspace.py`: reference artifact validation succeeded; six Fortran manifest executables compiled and passed with Intel `ifx`; workspace validation succeeded.
- `git diff --check`: passed with line-ending warnings only.

Previous verification after completing step 7 Fortran implementation:


```bash
python -m unittest discover -s scripts -p "test_*.py"
python scripts/validate_fortran.py
python scripts/validate_reference_artifacts.py
python scripts/validate_workspace.py
```

Result: all passed.
- `python -m unittest discover -s scripts -p "test_*.py"`: 57 tests passed.
- `python scripts/validate_fortran.py`: six Fortran manifest executables compiled and passed with Intel `ifx` through oneAPI env script.
- `python scripts/validate_reference_artifacts.py`: reference artifact metadata validation succeeded.
- `python scripts/validate_workspace.py`: succeeded.

## Next Agent Checklist

- Read `AGENTS.md`, `PLAN.md`, `PROGRESS.md`, and `WORKNOTE.md`.
- Confirm no other owner is active in this file.
- Correct the Abaqus-facing `UEL` wrapper/interface mismatch before `phases/uel-3d-euler-beam/step8.md`.
- Update this file when step status changes or before handing off.
