  "message": "[JSC][Temporal] Add pure C++ core layer: Rounding, ISOArithmetic, InstantCore, CalendarArithmetic\nhttps://bugs.webkit.org/show_bug.cgi?id\u003d314432\nrdar://176580834\n\nReviewed by Yusuke Suzuki.\n\nThe Temporal spec algorithms were previously inlined throughout the JS\nwrapper layer (TemporalDuration.cpp, TemporalPlainDate.cpp, etc.),\ntightly coupling spec math with JSGlobalObject* and JSValue. This patch\nextracts them into a pure C++ core layer under runtime/temporal/core/\nwith no JS VM types, enabling:\n- C++ unit testing without a JS engine (TemporalCoreTest.cpp, ~200\n  tests mirroring temporal_rs v0.2.3 test suite)\n- Spec step annotations and temporal_rs cross-references in every\n  function body for reviewer traceability\n- Cleaner separation between spec algorithm and JS binding layers\n\nCallers in TemporalDuration.cpp, TemporalPlainTime.cpp,\nTemporalPlainDate.cpp, ISO8601.cpp, etc. are updated to call the\nTemporalCore:: qualified names.\n\nTests: Source/JavaScriptCore/API/tests/TemporalCoreTest\nCanonical link: https://commits.webkit.org/312935@main\n",
