Hand-derived nonsquare GEMV [50,122] and GEMM [[58,64],[139,154]] pass. All copy, dot, norm, scale, axpy, GEMV, and GEMM calls cross CBLAS only inside .cpp files.

Review Fix Round 1 — matrix-storage-size-overflow

  • regression_test: tests/unit/math/matrix_test.cpp now constructs Matrix{SIZE_MAX / 2 + 1, 2} and requires std::length_error.
  • RED: cmake --build .harness/build --config Debug --target fesa_tests exited 0; ctest --test-dir .harness/build -C Debug -R DenseMath --output-on-failure exited 8 with 1/2 failures because the wraparound constructor threw nothing.
  • fix: Matrix computes its storage size through a checked helper before vector construction and rejects exactly columns != 0 && rows > SIZE_MAX / columns.
  • GREEN: the same targeted build and DenseMath CTest commands exited 0; 2/2 passed.
  • VERIFY: approved MSVC x64 configure and full Debug build exited 0; targeted DenseMath passed 2/2, discovery found 7 tests, and the full suite passed 7/7. The public-header MKL scan had zero matches, git diff --check exited 0, and git diff --exit-code -- reference/ exited 0.
  • scope: the deferred empty-dot review minor was not changed, reference artifacts remain untouched, and phase Step 9 status/timestamps were not modified.

  • contract_checks: the mapper consumes syntax-only ParsedInput and returns one complete immutable Domain or a categorized diagnostic. It enforces the monotonic top-level/part/assembly/step grammar, B33 only, identity instances only, exact inclusive set generation, case-insensitive references, stable declaration/instance-order internal IDs, and SourceEntityId {instance_name, source_label}. Direct node labels, part and assembly sets, ambiguous multi-instance labels/sets, and direct-versus-set constraint overlap are resolved before Domain success.
  • contract_checks: material and section mapping uses exact E,nu, G=E/(2*(1+nu)), A,I11,I12,I22,J, exact I12=0, Iy=I11, Iz=I22, and n1 -> local y. It requires positive E,G,A,I11,I22,J without adding a nu < 0.5 gate. Nonfinite material, section, and guide data are model failures. Overflow-safe scaled norms apply the exact length and guide-vector inequalities; equality fails, values above pass, and valid finite geometry near 1e308 is accepted without a fallback axis.
  • contract_checks: model-level and step-level boundaries and sole-step CLOAD targets are validated, conflicting expanded node/DOF prescriptions fail, the exact four positive finite *STATIC fields are retained, and the sole canonical result identity is Step-1, frame 0. The exact warning no-op allowlist produces stable ignored-input-keyword diagnostics without changing semantic objects.

  • handoff: AbaqusDomainMapper::map(const ParsedInput&), complete immutable Domain objects, stable expanded node/element/set identities, validated material/section indices, and the sole StaticStepDefinition are available to Step 13 AnalysisModel.

Step 12 Review Corrections

  • A duplicate-*ELASTIC regression test first failed because a second consecutive elasticity record lost the owning-material state. Preserving the immediate material eligibility produced the exact duplicate-entity diagnostic and restored targeted 5/5.
  • Ten monotonic-order regressions first failed at the accepted late-*PART case. Explicit phase state now rejects late model data, assembly sets before or followed by instances, element-before-node, incomplete block closure, and pre-*STATIC or out-of-order history data with invalid-keyword-location.
  • Review edge tests then failed for valid 1e308 geometry and for nonfinite elasticity being classified as input. Context-specific model parsing, overflow-safe scaled geometry comparisons, active beam-section context, exact GENERATE landing, direct/ambiguous target resolution, and exact threshold cases were added. The corrected focused suite passes 5/5 and the full accumulated suite passes 19/19.
  • Focused re-review returned Critical 0 and Important 0. Its sole remaining minor requested an explicit negative transverse-shear context assertion; that table case was added and passes without a production change.

Step 12 Root Review Fix Round 1 — same-token target ambiguity

  • finding: resolveNodeTarget returned one matching node set before computing the direct numeric source-label candidates. A token such as 1 therefore silently selected NSET=1 even when node source label 1 was also a valid interpretation.
  • regression_scope: RejectsUnsupportedAndInvalidPortfolio now constructs an NSET named 1 containing node 2 while node label 1 also exists, and exercises the same token independently through both *BOUNDARY and *CLOAD. It requires input-category unresolved-reference with exact keyword, entity identity 1, and original data-row file/line location.
  • RED-build: cmake --build .harness/build --config Debug --target fesa_tests exited 0 after registering the two regression paths.
  • RED-test: ctest --test-dir .harness/build -C Debug -R "InpDomainMapping.RejectsUnsupportedAndInvalidPortfolio" --output-on-failure exited 8. The test failed at same-token-boundary because result.hasValue() was true instead of the required structured failure.
  • fix: target resolution computes both name-matched node sets and numeric direct-node candidates before returning either. Multiple candidates within an interpretation or one valid candidate from each interpretation use the existing input/unresolved-reference ambiguity contract; unique set-only and direct-only paths remain unchanged.
  • GREEN: the targeted build exited 0 and ctest --test-dir .harness/build -C Debug -R InpDomainMapping --output-on-failure exited 0 with 5/5 passed.
  • VERIFY: approved explicit-dependency MSVC x64 configure and full Debug build exited 0; discovery found 19 tests including all five mapper names; full CTest passed 19/19. Backend/upward/core-upward/distributed-load/unapproved nu scans were 0, exactly five mapper tests remained, git diff --check exited 0, and reference diff/status were clean.
  • deferred_scope: the separate known-but-misplaced keyword diagnostic Minor was deliberately not changed in this fix round. No phase-index change and no commit were made.

  • green_triage: the first implementation build passed and the first focused run was 9/10. The single failure was isolated to a large-coordinate test fixture whose requested equality rounded to a represented length above the threshold.

Root numerical review — Fix Round 1

  • scope: all three Important findings addressed in src/fesa/elements/euler_beam_3d.cpp and the existing exact T16 tests; the two Minor findings were intentionally not changed in this round.
  • defect_RED: after adding finite-positive derived-overflow, derived-underflow, and length-scaled-underflow fixtures to existing T16-BEAM-007, ctest --test-dir .harness/build -C Debug -R EulerBeam3D.RejectsInvalidGeometryAndProperties --output-on-failure exited 8. All three invalid fixtures were accepted; the diagnostic path observed respectively a nonfinite stiffness with maximum inf, an all-zero stiffness, and a stiffness with a required bending coefficient underflowed to zero.
  • defect_GREEN: cmake --build .harness/build --config Debug --target fesa_tests exited 0 and the same focused CTest exited 0 with 1/1 passed. create() now requires derived EA, GJ, EIy, EIz and all ten distinct positive length-scaled axial/torsion/bending block magnitudes to be finite and strictly positive. This rejects arithmetic overflow/underflow as invalid-beam-property without a conditioning threshold.
  • invariant_hardening: production normalizedMatrixError now returns infinite error for any nonfinite operand, difference, scale, or quotient, so the two-point/closed-form 1e-12 invariant fails closed.
  • analytical_hardening: every nonzero reference in existing T16-BEAM-006 now checks abs(actual-reference)/abs(reference) <= 1e-9; only the explicitly zero free-end resultants retain an absolute check. This evidence-only change was expected to remain GREEN and its focused test passed without a production correction.
  • convergence_hardening: existing T16-BEAM-005 directly assembles aligned 1/2/4-element [v,rz] cantilever systems from public localStiffness() and localEquivalentLoad() only. It checks each exact signed constant transverse element load, solves a test-only dense reduced system, and uses independent five-point integration of interior cubic-Hermite displacement error against the quartic uniform-load solution. Both refinements are monotone and each observed order is 4 within 1e-8. No DLOAD, parser, Domain, or production assembly support was introduced. This evidence-only change was expected to remain GREEN and the T16-005/T16-006 focused run passed 2/2.

  • contract_checks: ParallelFor, SerialParallelFor, and TbbParallelFor expose only std::size_t and std::function in the public header. oneTBB headers/types remain private to parallel_for.cpp, and the normalized Fesa::TBB dependency is private to fesa_solver.
  • contract_checks: both implementations execute [0,count) exactly once and make count==0 a no-op. Deterministic result ordering is caller-owned: bodies write only their index-addressed slot, and this adapter performs no global sparse write, COO/CSR reduction, mutex, or atomic accumulation.
  • contract_checks: serial and oneTBB execution preserve the original body exception type and message. oneTBB cancellation may allow already-running indexed work to finish; callers receive the rethrown exception and must not infer a deterministic partial-completion count.
  • contract_checks: the adapter uses oneTBB's default caller-scoped scheduler; it creates no process-wide thread setting, global_control, or task arena, and does not override later MKL/TBB oversubscription coordination.

Step 17 Review Fix Round 1 — atomic test evidence

  • classification: test-evidence reliability hardening; no production defect was observed or corrected.
  • baseline_GREEN: before changing the test, ctest --test-dir .harness/build -C Debug -R ParallelFor --output-on-failure exited 0 with the existing production adapter passing 3/3. Because the review changes only how a test observes duplicate callbacks, no implementation-owned RED was expected or manufactured.
  • reliability_issue: the prior std::vector scalar writes were race-free only if the exact-once contract was already true. A duplicate concurrent callback for one index could write the same non-atomic scalar concurrently, making the negative case undefined instead of a deterministic test failure.
  • correction: T17-PFOR-001 now uses an explicitly initialized atomic zero-count counter and explicitly initialized per-index atomic visit counters. T17-PFOR-002 uses explicitly initialized atomic serial/TBB output slots plus per-index atomic visit counters. All callback increments use fetch_add(1, memory_order_relaxed) and post-execution assertions require every count to equal one, so duplicate same-index callbacks are observed without a data race. Output stores/loads are relaxed atomics because only per-slot observation is required after the blocking adapter returns.
  • scope: only tests/unit/assembly/parallel_for_test.cpp, this cumulative Step 17 section, and the ignored task-17-report.md changed. Production, CMake, the phase index, upstream contracts, and reference artifacts were not modified in this review round; the exact three test names remain unchanged.

  • contract_checks: SparseMatrix is a separate owning CSR type with 0-based row offsets and sorted-unique columns. It validates row-offset shape/range, column range/order/uniqueness, COO dimensions, expected-pattern membership, finite inputs, finite ordered sums, and multiply dimensions. Empty rows and rectangular/zero structural layouts remain valid; every expected slot is emitted even when its exact stored value is zero.
  • contract_checks: COO contributions are stable-sorted by exactly (row,column,elementOrder,localOrder) and duplicates are accumulated in that sequence. The cancellation fixture distinguishes tuple order from incoming vector order, and input permutation retains the same result.
  • contract_checks: SparseAssembler validates model/DOF dimensions, element references, and scatter ownership before work. It invokes the injected ParallelFor once over stable active-element order; each worker writes only its caller-indexed 144-entry row-major local buffer and failure slot. CSR allocation and reduction occur only after the parallel call.
  • contract_checks: the public headers expose no oneTBB, MKL, HDF5, or PARDISO type. SparseMatrix neither includes nor inherits dense Matrix; the math header forward-declares DofManager-owned SparsePattern to avoid a public upward include.
  • generated_evidence: .harness/build/src/fesa/Debug/fesa_solver.lib, .harness/build/tests/Debug/fesa_unit_tests.exe
  • reference_diff: unchanged; git diff --exit-code -- reference/ exit 0
  • handoff: Step 19 can consume canonical full CSR arrays and deterministic matrix-vector multiplication without depending on dense storage, oneTBB, or a solver backend. Step 20 remains solely responsible for PARDISO descriptors, indexing conversion, factorization, and substitution.
  • concerns: none; no implementation, environment, backend, or upstream contract conflict was found.

Step 18 Review Fix Round 1 — evidence artifact scope

  • classification: evidence/artifact-integrity correction only. Production, public headers, tests, CMake, upstream contracts, and phase-index content were not changed by this review fix.
  • reproduced_finding: before correction, git diff --check 59da6c6..HEAD exited 2 with 382 trailing-whitespace findings, all from tracked generated file .harness/step18-discovery.json. The cumulative changed_files list omitted that tracked file while listing ignored scratch file .superpowers/sdd/linear-static-3d-euler-beam/task-18-report.md as though it were tracked.
  • correction: deleted the generated discovery JSON with apply_patch and reconciled changed_files to the exact 10-file combined tracked scope. The ignored scratch report remains supplementary evidence and is not listed as a tracked Step 18 file.
  • phase_index_guard: git hash-object phases/linear-static-3d-euler-beam/index.json was 6808d3a8101f656e978b7e00df6cf1a4ad5f1711 before and after correction.
