The crate's core task (implementation/core-producer-connect): the producer half of src/producer.rs per producer.md, adapted to the crate's seam types and the alkcall 0.8.0 establishment surface. - The session-gate establisher (`socks5_session_establisher`): validates/records the opener identity (the CF-005/CF-006 seam, ADR-005) via the optional `identity_witness` probe (the alktunnels posture); returns `Establishment::default()` — no plan payload (the dial happens post-establishment; POC #1's wire note). - The pump handler (`make_socks5_pump_handler`): `accept_bi()` → the forked typestate over the `BiStream` (`accept_no_auth → read_command`) → dispatch. CONNECT: the dial seam (`DialFn`, ADR-004) at the command-read interception point; success: `reply_success(sentinel)` then `pump_bidi` awaited inline (R-02 — the JoinHandle tracks the data-plane lifetime). Refusal: `reply_error` with the mapped RFC code — no phantom data plane. - The ASSOCIATE/BIND arms land as RFC-faithful refusals (`CommandNotSupported`) — the pre-vertical posture (ADR-008); the dispatch skeleton + registration signature carry the seam parameters from day one so the associate/bind tasks swap the arms without touching the registration shape. - `register_socks5_openable`: spec + establisher + pump via `register_openable_with_establisher` (`timeout: None` = the 10s default), scope-gated `socks5:open`. Missing callbacks = those commands refuse RFC-faithfully, never a panic. - `serve_socks5_over<T>`: the substrate-free protocol entry (the POC shape), directly testable without channels; the builder (`Socks5Producer::builder()`) is the spec'd assembly shape. - Tests: 11 in-module (substrate-free duplex-driven — round-trip + half-close teardown, refusal mapping per variant, missing-dial refusal, ASSOCIATE/BIND arms, dispatch guard, establisher witness, builder shape) + 5 harness integration (end-to-end CONNECT echo with the identity witness, dial refusal 0x05 with no phantom data plane, scope-class refusal 0x02, ASSOCIATE/BIND refusals with CONNECT still serving, repeated CONNECTs on one registration). The harness retargeted to the real producer (`RegisterMode:: Producer`); the minimal stand-in is a harness-internal helper. Verification: cargo test 87+19+37 green; clippy --all-targets -D warnings clean; fmt clean; wasm check + wasm clippy clean; cargo doc clean; --all-features green.
