The wire protocol is re-specified as DongLoRa Protocol v2 (see PROTOCOL.md). Every type_id, tag-correlation rule, and field layout is incompatible with 0.1.0.
* Add PROTOCOL.md as the normative spec for the v2 wire format.
* Replace framing.rs with a streaming FrameDecoder that emits (type_id, tag, payload) triples on each COBS-delimited, CRC-checked frame.
* Split the single-file lib.rs into dedicated modules: frame, commands, events, errors, modulation, info, crc, chip_id. Re-exports preserve convenience imports at the crate root.
* Replace RadioConfig / Bandwidth with a Modulation enum covering LoRa, FSK/GFSK, LR-FHSS, and FLRC, each with its own typed parameter struct.
* Add TxFlags, RxOrigin, SetConfigResult, OkPayload to model v2 response shapes, and RadioChipId for GET_INFO.
* Rewrite fuzz corpus: replace the 4 cobs_* / command_roundtrip targets with decoder_feed, frame_roundtrip, lora_config_roundtrip, and parse_device_message; drop parse_radio_config.
* Expand proptest and mutation-killer coverage for the new wire shape.
* Rewrite canonical-byte test vectors against the v2 spec.
- Cargo.toml: add documentation and readme fields; expand the exclude
list so deny.toml, justfile, mise.toml, .github, .jj, fuzz, and any
cargo-mutants output never ship in the published tarball.
- README: badges, install snippet for both feature shapes, testing
matrix.
- CHANGELOG.md: keep-a-changelog skeleton with a 0.1.0 entry.
- Revert framing.rs let-chain back to nested if-let so the published
MSRV holds at the edition-2024 floor (1.85). Behaviour unchanged.
cargo publish --dry-run packages cleanly.
Ten properties covering: RadioConfig roundtrip and validate/resolve
determinism; no-panic on arbitrary bytes for both Command::from_bytes
and RadioConfig::from_bytes; bounded-capacity for Transmit payloads
(guards the heapless::Vec size); Command roundtrip via a test-only
encoder (the library only decodes commands); COBS reversibility; and
two streaming CobsDecoder properties (no-panic on random byte streams
with random chunk boundaries, and a full encode→feed→decode roundtrip).
Adds Clone to Command and Response — benign public-API expansion that
unblocks proptest's Just strategy.
Imports CobsDecoder and cobs_encode_response from firmware's
src/host/framing.rs, adjusted so the defmt::warn on encode overflow is
gated on the crate's defmt feature rather than an unconditional import.
The route_command helper stays in firmware — it depends on embassy
channels, which have no business in a transport-agnostic crate.
Copied src/protocol.rs from firmware verbatim, added crate-level #![no_std],
migrated the defmt::Format derive gate from cfg_attr(not(test), ...) to
cfg_attr(feature = "defmt", ...) so host-side (no-default-features) builds
compile cleanly. Tests unchanged; all 35 pass.
Firmware still owns the file for now — the re-export swap lands in a
follow-up firmware commit to keep each change standalone.
