name: Fuzz

# Short-duration fuzz run: weekly schedule + manual dispatch. Each target
# runs for 5 minutes with the committed seed corpus. For longer hunts, run
# locally: `cargo +nightly fuzz run <target> -- -max_total_time=1800`.
#
# We deliberately do NOT fuzz on every push -- runs are too long for that.

  schedule:
    # Mondays 04:15 UTC.
