  "message": "perf: move BuildHasher leaf functions after RandomState code for I-cache locality\n\nThe _with_hasher leaf functions (~600 lines) were interleaved between\nthe hot RandomState functions, polluting the instruction cache for the\ndefault path. Move all BuildHasherHashValue trait/impls and _with_hasher\nleaf functions to the end of the file (after create_hashes_with_hasher,\nbefore tests) so the hot default path stays tightly packed.\n\nCo-Authored-By: Claude Opus 4.6 \u003cnoreply@anthropic.com\u003e\n",
