- command_roundtrip: structure-aware (via arbitrary crate) Command
encode → parse → equal. Symmetric to cobs_roundtrip.
- cobs_decoder_multi_frame: chunked feeding with arbitrary split sizes;
asserts bounded payload and that command count never exceeds sentinel
count.
- cobs_chunk_invariant: same stream through two decoders (chunked vs
all-at-once) must produce the same command sequence.
Adds test-fuzz-long recipe (600s per target, ~1h 10m total) for CI
cron / pre-release. All seven targets smoke-tested at 100k runs each
with zero findings.
Four libFuzzer targets:
- parse_command: Command::from_bytes never panics; bounded payload.
- parse_radio_config: RadioConfig::from_bytes never panics.
- cobs_decoder_feed: CobsDecoder::feed is panic-free across arbitrary
byte streams split into arbitrary chunks.
- cobs_roundtrip: structure-aware (via arbitrary crate) Response →
cobs_encode_response → ucobs::decode yields identical raw bytes.
All four smoke-tested at 50k runs each with no findings. Intended CI
cadence is a weekly cron with a larger time budget; per-PR would be
expensive. Requires nightly + cargo-fuzz.
