Nonlinear Static Newton-Raphson Reference Comparison
Verdict
blocking-pass-with-review-only-findings. FESA HDF5 is the authoritative solver output. The
Abaqus CSV files are read-only external comparison evidence; the observed agreement does not imply
Abaqus S4 internal formulation, integration, stabilization, or recovery equivalence.
Overall handoff status: pass-for-physics-evaluation. This handoff classification records that
all blocking comparisons passed; the detailed verdict above remains
blocking-pass-with-review-only-findings because the six local RF/RM findings are review-only.
The literal execution order was ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT.
The COMPARE commands were
ctest --preset windows-msvc-ninja-debug -R "^NonlinearStaticReference\." --output-on-failure
(exit 0, 905.404 s, 9/9 passed), followed by
ctest --preset windows-msvc-ninja-debug -R "^(NonlinearStaticReference|ReferenceTolerance|Mitc4Reference)\." --output-on-failure
(exit 0, 930.617 s, 9/9 matched tests passed). The fresh full CTest run then passed 302/302;
its command and output tail are recorded in build-test.md.
Artifact check
Every input, displacement CSV, reaction CSV, and stress-inventory CSV was readable, finite where required, unique by declared source key, and identical before and after all copied-input executions.

Fine and coarse required nonlinear CSV rows had exact Frame=Increment 10: Step Time = 1.000.
The HDF5 /steps/Step-1/accepted_frames table had exactly one factor-one row: frame 9, increment
10, load factor 1.0, two Newton iterations. Reference copies and generated artifacts were confined
to these build-local directories:

Compare and classify
Rows were matched by (case_id, accepted_state, canonical_instance_name, source_node_label, component), never CSV order. Required HDF5 projections were factor-one
/steps/Step-1/frames/9/nodal/displacement, generalized_internal_force,
generalized_external_force, generalized_residual, reaction, /model/nodal_constraint_mask,
and /global/equilibrium; the linear control uses /steps/Step-1/frames/0/nodal/displacement.
All required source keys, components, uniqueness and finite checks passed before tolerance.
External families use docs/TOLERANCE.md: reference-only scale, near-zero band 0.01*S, row
relative limit 0.05, and family RMS limit 0.01. rows passed is the deterministic per-row
decision count; U is blocking and UR is warning-only.

Worst absolute rows were fine U PART-1-1/node 2/U3, fine UR
PART-1-1/node 442/UR1, coarse U PART-1-1/node 2/U3, coarse UR
PART-1-1/node 37/UR1, linear U PART-1-1/node 2/U3, and linear UR
PART-1-1/node 44/UR1. No warning-only family failed.
The eight blocking internal families are independent of Abaqus CSV tolerance.

Local reaction RF/RM source-key/inventory/finite prechecks passed, but the following direct row/RMS findings remain review-only and therefore do not change the blocking classification.

RM3 and stress were not numerically compared. Artifact inventory, byte size, timestamp, and
SHA-256 equality before/after all runs prove that no reference artifact changed.
