 ## Summary
 
-> To be filled on completion
\ No newline at end of file
+> Implemented src/websocket/upgrade.rs: WS upgrade handler at /alknet/call using axum
+> WebSocketUpgrade, bearer auth via shared bearer_auth_middleware (no token → 401),
+> resolved identity stored on CallConnection::new_overlay_only, native EventEnvelope
+> over binary WS messages (no length prefix, text → protocol close 1002), shared
+> Dispatcher::dispatch_requested for call.requested (AccessControl::check gates →
+> FORBIDDEN call.error), Dispatcher::handle_abort for call.aborted, responded/completed/
+> aborted correlated via PendingRequestMap, fail_all_pending on disconnect (ADR-016
+> cascade), bidirectionality via connection-local overlay. Wired /alknet/call route
+> into adapter.rs router. 168 tests pass (incl. round-trip, 401, FORBIDDEN, subscription,
+> disconnect abort, text-close, bidirectional overlay, no-length-prefix). Clippy clean.
