# Seeds

Curated, read-only, and small: the sizes where part arithmetic goes wrong.
Boundaries (the 5 MiB floor, the 5 GiB part ceiling, the 5 TiB object ceiling,
exactly 10,000 parts), the off-by-ones on either side of each, and the two
shapes that divide differently: an object that divides evenly into parts and one
that leaves a remainder.

They are NOT the corpus. Run the fuzzer with the corpus first and these second:

    cargo +nightly fuzz run plan fuzz/corpus/plan fuzz/seeds/plan -- -max_total_time=1800

libFuzzer writes new inputs into the FIRST directory only, so this arrangement
keeps the curated set curated and lets `fuzz/corpus/` grow.
