- Socks5ChannelSession::connect: open_channel(OP_SOCKS5_OPEN, {},
SOCKS5_ALPN) then the forked client typestate's use_stream path
over the channel BiStream (POC #1's fit); post-reply the session
is the raw byte pipe (0 B framing)
- Target construction via ToTargetAddr: IP-string forms parse to IP
targets, domain form passes through unresolved (ADR-012)
- split() borrowed halves (SplitPipe) / into_inner() owned pipe
(TakenInner — the session rides along as the teardown owner);
channel_id() for correlation
- Teardown ownership (alktunnels ADR-005 posture): Drop sync-reaps
the adopted entry (teardown_channel is sync; Drop cannot await) +
the pipe drop EOFs the producer pump structurally; close() is the
graceful path (write-half shutdown, then reap); the in-stream
refusal tears the channel down in connect (teardown-at-birth —
no phantom channel); no Clone (compile_fail doctest)
- Error surface: open failures are the typed SocksOpenError reasons
(ADR-049 §4); a refused target is the RFC reply code through
SocksSessionError::Rfc (consumer.md §Error surface)
- Harness: the consumer-side topology (wire_consumer_side[_with] —
the consumer dials with a real ChannelClient; the producer accepts
with the real registration) + witnessing_echo_dial; the
allow(dead_code) attr rides the alktunnels harness posture
- tests/consumer-connect.rs: 9 e2e tests — echo round-trip + CF-006
witness, target forms at the dial seam (ADR-012), refused dial →
typed RFC error + no phantom channel, FORBIDDEN open → typed open
error + no session, drop teardown + connection health, half-close
EOF semantics, into_inner pairing, Send shape
