-## Open questions for the migration plan
+## Resolved questions
 
-- **Phase 6 `accept_bi` semantics:** does `accept_bi()` on a
-  `from_bidi` connection yield the single bidi stream directly usable
-  as `AsyncRead+AsyncWrite`, or does it need a wrapper? Needs
-  verification against the `BidiStreamSource` impl for `from_bidi`
-  in `types.rs`.
+- **Phase 6 `accept_bi` semantics:** **Resolved.**
+  `StreamBidiStreamSource::accept_bi` yields the `(SendStream,
+  RecvStream)` pair once; the streams are already
+  `AsyncRead`/`AsyncWrite` adapters. The `QuicStream` wrapper is
+  redundant — delete it. The `BidiStreamSource` trait has a unified
+  intent; all three impls (quinn, iroh, stream) collapse into adapters
+  with the same shape. See Phase 6 above.
+- **Integration test home:** **Resolved.** The dial + take-over
+  composition test moves to `alknet-client/tests/` with a minimal echo
+  `ProtocolHandler` on a test ALPN — no `alknet-call` dependency, no
+  circular path. The call-protocol-specific tests stay in
+  `alknet-call` (rewritten to use `spawn_dispatch` + loopback
+  `Connection`). See Phase 5 / open questions above.
 - **Workspace `Cargo.toml`:** the three new crates need to be added to
-  the workspace member list. Trivial but worth noting.
-- **Integration tests (`tests/two_node_call.rs`):** the one integration
-  test file (331 lines, 2 tests) calls `client.connect()` twice and
-  builds its own raw quinn server (`build_raw_quinn_server`, lines
-  58-94 — hand-rolled rustls + quinn server config, no
-  `AlknetEndpoint`). Both tests (`call_round_trips_over_quic_loopback`
-  and `from_call_discovers_and_forwards_over_quic_loopback`) need the
-  `connect` path replaced with `AlknetClient::dial_quic` +
-  `spawn_dispatch`. The server side (`build_raw_quinn_server`) should
-  eventually use `AlknetEndpoint` + `TlsServerConfig`, but that's a
-  larger rewrite — for Phase 5, the minimal fix is to replace just the
-  client `connect` call with the dial + take-over composition. The
-  server-side raw quinn setup can stay (it's a test helper, not
-  production code). This integration test will need
-  `alknet-call` to dev-depend on `alknet-client` (or the test moves to
-  `alknet-client`'s own integration tests). The cleaner option: move
-  `two_node_call.rs` to `alknet-client/tests/` once `alknet-client`
-  exists (Phase 3), since it's testing the dial + take-over
-  composition, not just the protocol.
