Progress

Current State

• Project direction is defined as a Korean FEM surrogate tutorial using NumPy/SciPy 2D Euler-Bernoulli beam/frame analysis and scikit-learn surrogate models.
• Documentation files have been populated for PRD, architecture, ADR, and model-specific theory.
• BeamExamples/CantileverBeam.txt and BeamExamples/CantileverBeam_Displacements.txt are designated as canonical solver verification fixtures.
• Implementation work is active on branch codex/harness-implementation.

Completed

• Replaced template project instructions in AGENTS.md.
• Removed UI-oriented documentation from the planned scope.
• Added theory document structure under docs/theory/.
• Updated PRD and architecture to require BeamExamples-based solver regression verification.
• Added PROGRESS.md and WORKNOTES.md as mandatory handoff files and documented their workflow in AGENTS.md.
• Created Harness phase files under phases/.
• Completed phase 0-project-foundation step 0: pyproject.toml, package skeleton, artifact directories, and lint configuration.
• Completed phase 0-project-foundation step 1 with TDD: package import smoke tests and femsurrogate.__version__.
• Completed phase 1-beam2d-solver step 0 with TDD: BeamExamples input and displacement parser.
• Completed phase 1-beam2d-solver step 1 with TDD: frame local stiffness and transformation matrix.
• Completed phase 1-beam2d-solver step 2 with TDD: sparse global assembly, constrained DOF handling, load vector assembly, and linear static solve.
• Completed phase 1-beam2d-solver step 3 with TDD: BeamExamples displacement regression and analytical cantilever tip check.
• Completed phase 2-dataset-and-surrogates step 0 with TDD: LHS sampling, dataset schema, Beam2D case runner, and dataset builder.
• Completed phase 2-dataset-and-surrogates step 1 with TDD: common split/evaluate utilities, metrics, timings, and prediction table.
• Completed phase 2-dataset-and-surrogates step 2 with TDD: scikit-learn model builders and registry for RSM, GPR, Random Forest, Gradient Boosting, and MLP.
• Completed phase 2-dataset-and-surrogates step 3 with TDD: plotting diagnostics and metric comparison helpers.
• Completed phase 3-notebooks-and-final-verification step 0: dataset notebook, reference CSV, and metadata JSON.
• Completed phase 3-notebooks-and-final-verification step 1: five surrogate model notebooks with metrics, predictions, and diagnostic figures.
• Completed phase 3-notebooks-and-final-verification step 2: comparison notebook and model comparison outputs.
• Completed phase 3-notebooks-and-final-verification step 3: full pytest, ruff, and all notebook execution checks.

In Progress

• None.

Blockers

• None recorded.

Verification

• Documentation checks were run manually with PowerShell/rg to confirm required BeamExamples references and absence of stale template terms.
• Verified that AGENTS.md references PROGRESS.md and WORKNOTES.md, both files exist, and stale template terms are absent.
• uv sync passed.
• uv run python -c "import femsurrogate; print(femsurrogate.__name__)" printed femsurrogate.
• uv run ruff check . passed after excluding existing local harness infrastructure from ruff scope.
• RED: uv run pytest tests/test_project_structure.py -q failed because femsurrogate.__version__ was missing.
• GREEN: uv run pytest tests/test_project_structure.py -q passed with 2 tests.
• uv run ruff check . passed.
• RED: uv run pytest tests/test_beamexamples_io.py -q failed because femsurrogate.fea.io did not exist.

• uv run ruff check . passed after solver import formatting was corrected.
• RED: uv run pytest tests/test_cantilever_fixture_regression.py -q failed because femsurrogate.fea.benchmark did not exist.
• Regression discovery: fixture comparison then exposed an Rz sign convention mismatch; the element convention was aligned to BeamExamples clockwise-positive Rz.

Next Actions

• Review generated tutorial outputs and continue with documentation polish or additional explanatory notebook text if desired.
