# Each target is retried once before the build fails. The Go fuzzing coordinator
# reports "context deadline exceeded" when -fuzztime elapses while a worker is
# mid-iteration; that is a harness artefact rather than a corpus failure, it
# lands on a different target from run to run, and it writes no failing input.
# A real failure is deterministic — the input is written under testdata/fuzz and
# replayed from the corpus — so it survives the retry, as does a genuine hang.
