    "error": "",
    "body": "## Symptom\nThe Mac's data volume drops to near zero free space; Finder's storage view and `du` of the home folder don't explain it.\n\n## Cause\nChrome leaves a full code-signing clone of itself on launches under the per-user temporary directory: `$(getconf DARWIN_USER_TEMP_DIR)/../X/com.google.Chrome.code_sign_clone`. Observed: 26 clones, 37 GB apparent (~8 GB real, APFS clones), and growing.\n\n## Fix\n```bash\nD=\"$(getconf DARWIN_USER_TEMP_DIR)/../X/com.google.Chrome.code_sign_clone\"\ndu -sh \"$D\"; ls -lt \"$D\"\n# keep the 2 newest, remove the rest (quit Chrome first)\nls -t \"$D\" | tail -n +3 | while read c; do rm -rf \"$D/$c\"; done\n```\n\n## Verify\n`df -h /System/Volumes/Data` shows the space returned.\n\n## Notes\nCheck this location first in any \"Mac disk suddenly full\" investigation.",
