  "message": "Replace most usages of SyscallCache with the weaker XattrProvider. SyscallCache is unsafe to use with files that may change over the course of the build, like outputs and files in external repositories. The weaker XattrProvider type helps to ensure that a stale cached value is not used.\n\nAlso thread SyscallCache through to IncludeParser.\n\nFilesystemValueChecker is still using SyscallCache on outputs/external repository files. It will be fixed in a follow-up.\n\nPiperOrigin-RevId: 433254855\n",
