The TCP BIND dispatch arm replaces its refusal with the full phase model (POC #5-validated scope), plus the command gate at dispatch: - The command gate: TCP BIND requires socks5:bind from the per-call opener identity (CF-005/CF-006) — the pump handler resolves it from the open-op AuthContext; serve_socks5_over<T> takes the resolved can_bind boolean explicitly. A scope-less identity gets the RFC-faithful ConnectionNotAllowed (0x02) with no factory call (the gate precedes the seam) while CONNECT still serves it. - The phase model (wire.md §BIND): the BindAcceptFactory at the command-read interception point → reply#1 carrying BND.ADDR (the factory's bind_addr) → the quiet wait (single-shot select!, exactly two exits: the one accept, or the control stream's EOF/garbage/ error; any byte = protocol garbage → session ends, no data plane; the accept future's drop IS the client-gone teardown) → reply#2 carrying the peer address (via the fork's published new_reply) → pump_bidi inline (the CONNECT shape, R-02). - Two-stage RFC-faithful failure mapping: factory failure → reply#1's mapped code; accept-stage failure → reply#2's mapped code, no data plane. No phantom listeners, no phantom data planes. - The no-factory default is the wrapper-aware in-band variant (ADR-007 variant 3, documented): sentinel reply#1 + sentinel reply#2 (0.0.0.0:0), the full phase model preserved — the channel is the connection. - The accept wait lives in the teardown-governed pump phase, never under the establishment bound (ADR-007). Tests: 16 unit tests (raw RFC client over duplex) + 7 harness integration tests over channels — happy path, the gate (0x02 while CONNECT serves, both scopes), quiet-wait garbage, client-gone teardown (owner-flag witness), both failure stages over channels, no-factory variant 3, and the three-command regression guard (CONNECT serves, BIND serves under its gate, ASSOCIATE still refuses). Verification: cargo test green (96 lib + 26 harness + 37 differential); clippy -D warnings clean (all targets, native + wasm32-unknown-unknown); cargo fmt clean; wasm check clean.
