Break the tty spec set (docs/architecture/crates/tty/) into atomic,
dependency-ordered tasks across two crates:
alknet-tty (lean core, depends on alknet-core only — ADR-057):
- crate-init, wire-codec, control-messages, negotiation, backend-trait,
adapter, review-tty
alknet-tty-local (sibling, portable_pty + libc — ADR-054):
- crate-init, pty-mode, pipe-mode, backend-impl, review-tty-local
integration:
- local-feature-reexport, integration-test, review-tty-final
Three review checkpoints at critical points: after the core crate (before
the local backend builds on the one-way-door TtyBackend trait — ADR-053),
after the local backend (validating REQ-TTY-01/02 and ADR-056), and a final
merge-readiness review. The high-risk tasks (backend-trait, adapter,
pty-mode) are flagged; the ADR-056 kill-on-Drop guard the POC lacked is
called out in both pty-mode and pipe-mode.
Validated with taskgraph: 115 tasks, no cycles, 10-generation parallel
structure with 3-way parallelism after crate-init and 2-way after the
backend trait.
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
