+## Description
+
+Port the shared types the whole server subsystem hangs off:
+`DecoyConfig` (NotFound/StaticSite/Redirect), `RouterState` (registry,
+identity provider, decoy — with axum `FromRef` impls), and the
+module skeleton for `src/server/`. Ported from
+`/workspace/@alkdev/alknet/crates/alknet-http/src/server/adapter.rs`
+(the type definitions) and `server/mod.rs`.
+
+## Acceptance Criteria
+
+- [ ] `DecoyConfig`, `RouterState` ported with the 6-endpoint reserved-path doc comments
+- [ ] `alkcall::core::auth::IdentityProvider` / `alkcall::registry::registration::OperationRegistry` type paths correct
+- [ ] No comments in code (project convention); doc comments on public API only
+- [ ] `cargo clippy --all-targets -- -D warnings` clean

+## Description
+
+Port `healthz` (`server/healthz.rs` — raw 200 "ok", no auth, no call
+protocol) and the decoy fallback (`server/decoy.rs` — fake nginx-style
+404, static site, or redirect per `DecoyConfig`). Ported from
+`/workspace/@alkdev/alknet/crates/alknet-http/src/server/{healthz,decoy}.rs`.
+Tests: healthz responds without auth; decoy serves all three configs.
+
+## Acceptance Criteria
+
+- [ ] `/healthz` returns 200 text/plain without auth
+- [ ] Decoy fallback for unmatched paths per DecoyConfig (404/static/redirect)
+- [ ] Reserved paths (6 gateway + /healthz + /openapi.json + /mcp + /alk/channels) never hit the decoy
+- [ ] `cargo test` passes

+
+## Description
+
+Targeted POC validating the WS↔byte-stream adapter contract (OQ-01)
+before the production implementation: wrap axum's `WebSocket` as
+`AsyncRead + AsyncWrite` such that alkcall's `ChannelsAdapter` demux
+and mux run over it correctly.
+
+Inbound: axum WS messages → shared bounded buffer → `AsyncRead` drains
+(backpressure via the alknet-tty precedent: try_send → Full → Pending).
+Outbound: `AsyncWrite` accumulates into a pending buffer; a task parses
+outgoing 8-byte chunk headers (verified: header+payload are separate
+writes; channel 0's write_frame is prefix+body separately) and emits
+each complete chunk as one WS binary message; chunks over the WS
+message cap (~1 MiB default) split across messages. Close: WS close →
+transport EOF (REQ-CH-02); `AsyncWrite::shutdown` → zero-length
+sentinel then Close frame (REQ-CH-01).
+
+## Acceptance Criteria
+
+- [ ] POC: adapter + ChannelsAdapter + channel-0 Dispatcher over `tokio::io::DuplexStream` pairs — call round-trip works
+- [ ] POC test: 16 MiB chunk splits across WS messages and reassembles
+- [ ] POC test: interleaved channel writes preserve chunk integrity (no torn chunks)
+- [ ] OQ-01 sub-items (a)-(d) resolved with concrete values, written back into open-questions.md
+- [ ] Findings + go/pivot recommendation recorded in this task's Summary

+
+## Description
+
+Port the connection-local Layer 2 overlay verification from
+`/workspace/@alkdev/alknet/crates/alknet-http/src/websocket/overlay.rs`
+to the channels-over-WS session: a WS client registers ops (via
+call-protocol registration on channel 0), the hub reaches them through
+the live connection handle's `overlay_env()` — not PeerRef. Tests:
+hub→browser call over the same session; overlay ops die on disconnect;
+AccessControl gating on browser ops; bidirectional concurrent calls
+(both sides initiating on channel 0).
+
+## Acceptance Criteria
+
+- [ ] Hub→browser call test passes (browser registered an op, hub invokes it)
+- [ ] Disconnect drops overlay; subsequent reach attempts fail cleanly
+- [ ] Concurrent bidirectional calls don't deadlock or cross-correlate
+- [ ] `cargo test` passes

+
+## 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
+- [ ] `cargo test` passes
