  "message": "Reorder fields in `QuicCryptoNegotiatedParameters` to reduce its size from 360B to 352B (go/memory-cy).\n\nAs part of go/memory-cy, this CL reorders the fields of `quic::QuicCryptoNegotiatedParameters` to reduce its size from 360B to 352B. For single allocations, this drops the TCMalloc size class from 448B to 352B, saving ~498.0 GiB of fleet RAM.\n\nTo ensure no GCU regressions, we checked field-level `heapaccessz_all_loads` profiles and confirmed that hot fields are not split or displaced across 64-byte cache lines. We will also monitor for any GCU regressions with `gwp-cl-impact`.\n\nEDIT_CATEGORY: CATEGORY_TYPE_FIELD_REORDERING\nFULLY_QUALIFIED_TYPE_NAME: quic::QuicCryptoNegotiatedParameters\n#gwp-cl-impact\n\nTested:\n    Local presubmit tests failed.\n    Some test failures are present; the CL author decided to mail\nPiperOrigin-RevId: 991092377\n",
