fuzz:
name: fuzz smoke (60s per target)
# Fuzz is expensive (~10 minutes for 10 targets x 60s) and rarely
# surfaces regressions that block a PR. Run only on pushes to main
# so PR cycle time stays short; main still gets the post-merge sweep.
name: fuzz smoke (15s per target)
# Fuzz is gated to main pushes to keep PR cycle time short, and each
# target runs for 15s instead of 60s so post-merge runs finish in
# ~3 min instead of ~10. Smoke runs catch crashes from the existing
# seed corpus; longer campaigns are better done locally or on a
# dedicated schedule when needed.
