The logic is using bazel Runfiles API per Jon's suggestion. One of the scenarios used by the fuzzing framework is to place the binary and its runfiles into a folder, resulting in a directory layout like this: [temp dir] fuzzer fuzzer.runfiles/ Tested: bazel test -c opt explorer/fuzzing:explorer_fuzzer bazel build -c opt explorer/fuzzing:explorer_fuzzer + run the binary from various locations
