• contract_checks: SourceEntityId preserves numeric and raw label forms; sortDiagnostics() applies the fixed file/line/keyword/entity/code tuple with stable discovery-order ties; Status owns sorted diagnostics and optional failure category; Result<T> owns either a value or failed status and rejects both failed value access and construction from an OK status.

• contract_checks: Vector accepts zero size, owns contiguous doubles, deep-copies, leaves moved-from objects empty and usable, checks every index, and rejects dot/axpy mismatches; Matrix accepts zero dimensions, owns row-major contiguous doubles, deep-copies, leaves moved-from objects empty and usable, checks every index, and rejects GEMV/GEMM mismatches. 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. Windows tests stage the package-resolved oneMKL/OpenMP runtime before post-build discovery because the exact shell does not assume oneAPI in PATH.

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: ParsedInput records the absolute lexically normalized source path and exact binary-byte FNV-1a identity formatted as fnv1a64: plus 16 lowercase hexadecimal digits. Keyword and parameter names alone become ASCII uppercase; parameter values, data label lexemes, empty and trailing data fields, and each keyword originalLine preserve source spelling. Comments and blanks remain excluded while physical 1-based file line accounting is retained. Unreadable file, empty keyword, and orphan data return categorized input diagnostics. No keyword allowlist, wrapper/nesting, numeric conversion, B31/B33, or output-request decision exists in this Step. The read-only legacy input parses as 30 keyword blocks with exact identity fnv1a64:04543464cc970405, unchanged bytes, and unchanged modification time.

• 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. B31, transforms, nested/dependent assembly semantics, second step, NLGEOM, unknown keywords, and *DLOAD fail; no distributed-load Domain object, B31 alias, multi-step path, or transform fallback exists.

• 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.

• contract_checks: AnalysisModel stores one non-owning const Domain* plus stable EntityIndex vectors only. All Domain elements are active in stable internal order; reachable material and section IDs are deduplicated by an ascending internal-index scan; boundary/load IDs are the sole step's vector positions. domain() and step() preserve exact address identity, and the tests verify semantic storage addresses and values remain unchanged. Missing and multiple steps return categorized invalid-model-cardinality and unsupported-multiple-step diagnostics. No equation numbering, constraint propagation, multi-step activation, or numeric analysis state was added.

• contract_checks: full DOFs follow stable node index and exact component order [UX,UY,UZ,URX,URY,URZ]; free equations and constrained DOFs are ascending full-index mappings. Case-insensitive node-set and direct source-label targets expand deterministically; equal overlap is retained once, while different values return conflicting-boundary-condition at the conflicting row's source location. prescribedValues() has the same size/order as constrainedDofs() and preserves zero and nonzero values.
• contract_checks: each active B33 definition has one 12-entry scatter in endpoint/component order. The full-space CSR pattern has 19 row offsets and 252 sorted-unique structural columns for the two-element chain fixture. Stable free/constrained maps reconstruct the full vector without adding an API absent from the exact ledger. Node and element records remain unchanged and contain no equation IDs; no penalty, MPC, RBE, or sparse numeric storage was added.
