openfoam+stella: 5-MOAD scan; openfoam-0002 CWE-407, stella CLEAN
openfoam-0002: CFCFaceToCellStencil::calcCellStencil allGlobalFaces dedup
uses findIndex() O(G) linear scan inside nested forAll(cells)*forAll(faces)
loop. Developer left comment "Note:should use hashset?" — confirmed defect.
Fix: labelHashSet seen replaces findIndex, 77x op-count speedup at C=2000/F=12.
stella: all 5 MOADs CLEAN. BreakpointMap uses unordered_map O(1); TrapArray
uses std::array<uInt8,0x10000> O(1); single-threaded, no credentials, no
thread-local identity, no thundering herd.
