Add 18 integration tests in crates/alknet-tty-local/tests/ exercising the full stack (LocalTtyBackend + TtyAdapter::drive_session over tokio::io::duplex, real commands), validating the two crates work together through the TtyBackend trait seam. Tests live in alknet-tty-local (not alknet-tty) per the feature-gate deviation: the cyclic dependency alknet-tty → alknet-tty-local → alknet-tty prevents alknet-tty from depending on alknet-tty-local, so the integration tests live in the crate that depends on both. Unix-only tests (signal, process-group) use #[cfg(unix)]. PTY mode (8): happy path echo, interactive cat round-trip, resize, SIGINT signal, process-group signal (REQ-TTY-02), stdin EOF sentinel, cancel cleanup (ADR-056), exit-chunk-is-last (ADR-055). Pipe mode (6): happy path echo, separate stderr, SIGTERM signal, cancel cleanup, resize no-op, stdout chunk + sentinel. Negotiation errors (5): unknown_backend, malformed_negotiation (bad JSON, carriage != raw, empty cmd), allocate_failed (nonexistent binary). A shared test harness (tests/common/mod.rs) provides the client-side wire protocol helpers: write_negotiation, write_chunk, write_control, try_read_chunk, read_chunk_timeout, read_error_frame (asserts the 0x00 first-byte framing-disambiguation invariant), read_until_exit, assert_no_more_chunks, close_write_half, plus spawn_session which wires drive_session over a duplex pair with a test identity carrying tty:open. Verification: cargo test -p alknet-tty-local (42 tests pass), cargo clippy -p alknet-tty-local -- -D warnings (clean), cargo fmt --check -p alknet-tty-local (clean).
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
