The test suite spawns the grep binary inside per-test temporary directories (via uutests). With a relative LLVM_PROFILE_FILE, each subprocess wrote its .profraw into that tempdir, which gets deleted when the test ends, so the binary executing the src/ code left no coverage data and grcov reported every line as a miss (0%). Anchoring the path to the workspace root makes the profraw files survive, raising reported coverage from 0% to ~96%.
