Plan updated with the alknet-tty findings: the drainer pattern (single ordered writer) makes outbound chunk-boundary parsing sound; TestStdinSink's try_send→Full→Pending is the inbound backpressure precedent; OQ-01(a) now cites the reference. Task graph (taskgraph-validated, 17 tasks, 6 generations, no cycles): - tasks/server/: core-types, auth, healthz-decoy, adapter - tasks/gateway/: dispatch, routes, publish - tasks/websocket/: byte-adapter (research POC), upgrade-session, overlay-ops - tasks/adapters/: from-openapi, from-jsonschema, to-openapi, from-wss, mcp - tasks/client/: http-host - tasks/infra/: integration-suite (phase 4) Critical path runs through server core → adapter → WS session → overlay tests → integration suite. High-risk tasks are the three WS tasks, de-risked by the ws-byte-adapter POC blocking upgrade-session.

Description
Implement the WS upgrade handler per ADR-067/websocket.md, production
shape: axum route at /alk/channels; bearer auth on the upgrade
request (401 without token); upgrade → adapt the WS stream with the
byte-adapter (ws-byte-adapter) → Connection::from_bidi(ws_stream, b"alk/channels") → run the channels accept path: alkcall
ChannelsAdapter in-line demux with the install_channel_zero hook
constructing channel 0's CallConnection (identity attached) and
running Dispatcher::run_loop_single_stream. Text messages rejected
(WS close 1002). Overlay-only session construction mirrors the alknet
upgrade.rs::run_ws_session shape but through the channels machinery.
Acceptance Criteria
- Upgrade route wired into HttpAdapter's router (reserved-path collision rule respected)
- End-to-end test: WS client (tokio-tungstenite or axum test client) → upgrade → chunk-framed call.requested on channel 0 → response received
- Browser-style test: services/list via channel 0, AccessControl-filtered
- Disconnect mid-call: pending requests failed, overlay dropped, no hang
- 16 MiB chunk split/reassembly test carried over from the POC
