Suggestion: Decoding user-provided hex with expect will panic on invalid input (odd-length or non-hex characters), causing an abrupt crash instead of a normal CLI error path. Replace this with explicit error handling that prints a friendly message to stderr and exits with a controlled non-zero status. [logic error]
Severity Level: Major ⚠️
- ❌ `codec decode` crashes on malformed hex input.
- ⚠️ CLI users see panic/backtrace instead of clear error.
- ⚠️ Developer tool less robust for manual testing flows.Steps of Reproduction ✅
1. Build and run the CLI with the decode subcommand, e.g. `cargo run --package
byteport-cli -- codec decode abc` (entrypoint `main` in
`crates/byteport-cli/src/main.rs:104-119` uses clap to parse this into `Command::Codec {
action: CodecAction::Decode { hex: "abc".into() } }`).
2. `main` dispatches to `run_codec` (`crates/byteport-cli/src/main.rs:121-135`), which
matches on `CodecAction::Decode { hex }` at line 130 and executes `let decoded =
codec.decode(hex.as_bytes()).expect("decode should succeed");` at line 131.
3. `WireCodecAdapter::decode` implementation in
`crates/byteport-transport/src/ports/codec.rs:79-103` checks `if input.len() % 2 != 0` at
line 90 and returns `Err(io::Error::new(io::ErrorKind::InvalidData, "hex input length must
be even"))` for odd-length input like `"abc"`, and similarly returns `Err` for invalid
characters in `parse_hex_nibble` at lines 118-127.
4. The `Err` from `codec.decode` is unwrapped via `.expect("decode should succeed")` at
`main.rs:131`, causing the process to panic with the message `"decode should succeed"`
instead of printing a user-friendly error and exiting with a controlled non-zero status.

Suggestion: The transport ping flow claims to send and receive, but it never calls recv; it only dumps the internal TX buffer via take_tx, which bypasses the transport receive contract. Use recv (with prepared RX data if needed) so the command actually exercises the receive path it advertises. [incomplete implementation]
Severity Level: Major ⚠️
- ⚠️ `transport ping` never exercises the `recv` path.
- ⚠️ CLI help promises receive semantics not actually used.
- ⚠️ Developer transport adapter receive logic untested via CLI.Steps of Reproduction ✅
1. Run the transport ping subcommand, e.g. `cargo run --package byteport-cli -- transport
ping hello`, which clap parses into `Command::Transport { action: TransportAction::Ping {
data: "hello".into() } }` via `main` in `crates/byteport-cli/src/main.rs:104-119`.
2. `main` dispatches to `run_transport` (`crates/byteport-cli/src/main.rs:137-148`), which
creates a `WireTransportAdapter` and calls
`transport.connect("memory://pipe").expect("connect");` at lines 138-139.
3. In the `TransportAction::Ping { data }` branch at lines 141-146, the code calls `let
sent = transport.send(data.as_bytes()).expect("send");` at line 142 and prints `"Sent
{sent} bytes"`, then calls `let echoed = transport.take_tx();` at line 144 and prints
`"Echo (tx buffer): ..."` at line 145; there is no call to `transport.recv(...)` anywhere
in this function.
4. The `Transport` trait and `WireTransportAdapter` implementation in
`crates/byteport-transport/src/ports/transport.rs:3-17` and `114-151` define a proper
`recv` method backed by an `rx` buffer (with `push_rx` helper at lines 103-106 to seed
data), but `run_transport` never invokes `recv`, so the advertised behavior "Connect,
send, and receive through an in-memory wire transport." (doc comment on
`TransportAction::Ping` at `main.rs:78-83`, used as help text by clap) is not actually
exercised: the ping command only inspects the internal TX buffer via `take_tx`.

Summary
Lift recovered tools CLI crate (
byteport-cli) into a PR branch, providing a developer CLI for codec, transport, UI, and upload operations via thebyteport-transportcrate.Context
This is the final step of E4 (lift recovered tools CLI to branch + open PR), following E3 which recovered the
byteport-clicrate from stash-1. The crate exercises allbyteport-transportport abstractions (codec, wire transport, terminal UI, mock UI, S3 upload) through aclap-based command-line interface.Changes
crates/byteport-cli/— new crate with aclapCLI binary supporting 4 subcommand families:codec encode/decode— hex encode/decode viaWireCodecAdaptertransport ping— in-memory wire transport send/receive viaWireTransportAdapterui view/prompt— terminal UI view rendering + mock prompt flowupload— S3 upload instruction generation viaS3UploadTransportCargo.toml— addedcrates/byteport-clito workspace membersREADME.md— added work-state header sectionCargo.lock— updated for workspace changesTesting
