Is it guaranteed (even with broken or malicious backends) that the output path will never contain .. references or start with a /? Should we check that the resulting path dst is still below the captureCorruptedOutputsDir just to make sure? 🤔

We are safe here since outputPath is what we obtained from skyframe and send to remote execution backend (something like bazel-out/darwin-fastbuild/bin/...).
It is a path relative to the working directory (or input root depends on the flags) when the remote backend executing the action.

However, I added the check in case the invariance changed in the future. Thanks for the catch!

Which when set, Bazel will save outputs whose digest does not match the expected value to the target directories. Also use OutputDigestMismatchException to indicate the error and include output path in the error message. The message for such an error will become e.g.: ``` com.google.devtools.build.lib.remote.common.OutputDigestMismatchException: Output bazel-out/darwin-fastbuild/bin/output.txt download failed: Expected digest '872af2fe77729717832d0a020ae87a93b8b944146a2af6b3490491e1eaf1dc74/29229' does not match received digest '872af2fe77729717832d0a020ae87a93b8b944146a2af6b3490491e1eaf1dc74/29229'. ``` Used to support bazelbuild/continuous-integration#1175. Closes bazelbuild#13568. PiperOrigin-RevId: 378624823
