+## 작업
+
+1. `MITC4-DOF-001..003` tests를 먼저 작성한다.
+2. 기존 node DOF order `[ux,uy,uz,urx,ury,urz]`를 유지한다.
+3. B33 12-entry scatter를 보존하면서 shell four-node/source-order 24-entry typed
+   scatter와 sorted unique sparse pattern을 `DofManager` 단독 소유로 추가한다.
+4. Free/constrained numbering과 no/mixed/all constraint, nonzero prescribed value
+   round trip을 shell-sized system에서 검증한다.
+5. All-constrained `0x0 Kff`가 valid하도록 existing constraint behavior를 보존한다.
+
+## Acceptance Criteria
+
+```powershell
+$requiredBuildPaths=@("C:/git/googletest","C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl","C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb","C:/Program Files/HDF_Group/HDF5/2.1.1/cmake")
+foreach($p in $requiredBuildPaths){if(-not(Test-Path -LiteralPath $p)){throw "Missing $p"}}
+cmake --fresh -S . -B .harness/build -G "Visual Studio 18 2026" -A x64 `
+  "-DFESA_GTEST_SOURCE_DIR=C:/git/googletest" `

+```
+
+Current 12-entry-only behavior의 expected RED 뒤 minimal GREEN. 이후:
+
+```powershell
+cmake --build .harness/build --config Debug --target fesa_unit_tests
+ctest --test-dir .harness/build -C Debug -R "DofManager|EssentialConstraints|DomainModel" --output-on-failure
+cmake --build .harness/build --config Debug
+ctest --test-dir .harness/build -C Debug --show-only=json-v1
+ctest --test-dir .harness/build -C Debug --output-on-failure
+```
+
+## 검증 및 상태 갱신
+
+RED/VERIFY evidence를 기록하고 current Step의 Codex-owned fields만 갱신한다.
+
+## 금지사항
+
+- Node/Element에 equation id를 저장하지 마라.
+- Load/constraint ownership이나 sparse reduction을 이동하지 마라.
+- 기존 B33 scatter behavior를 제거하지 마라.
+- 직접 commit/hook 실행 또는 reference/upstream 변경을 하지 마라.
