- Replace on_worker_connected() post-hoc call with WorkerConnectedCallback
that fires inside CallAdapter::handle(). handle() blocks until disconnect
— there is no 'after handle accepts' point for the assembly layer to
hook into. The callback carries both on_connected (from_call + attach_peer)
and on_disconnected (detach_peer + drop channels).
- Add CallAdapter::with_worker_connected_callback(callback) builder method.
- Consolidate duplicate WorkerConnectedCallback struct definitions.
- Fix channel role: 'channel proxying' → 'channel management'. The hub
tracks channels; it does not proxy streams. What the caller does with
the resulting channel is the assembly layer's business.
- Resolve OQ-54: callback is the committed design. Update OQ file and
open-questions.md table.
Three ADRs addressing gaps surfaced by the first hub consumer (alkapi):
- ADR-067: Aggregated peer-env wiring — Dispatcher::with_aggregated_env hook
so compose_root_env reads a shared PeerCompositeEnv across all calls,
not a fresh per-call one. The hub-defining gap (alkapi OQ-08 / G.1).
- ADR-068: PeerCompositeEnv::peer_operations override — adds
list_operation_names() to OperationEnv, overrides on OverlayOperationEnv
and PeerCompositeEnv. Fixes services/list-peers returning empty operation
lists for non-local peers (alkapi G.6).
- ADR-069: from_call is a manual free function, not auto-wired — reverses
the aspirational OQ-27 resolution to match the implementation. Cleans
the 'v1 default' hedging language in ADR-017 and client-and-adapters.md
(alkapi G.4).
New crate spec: alknet-hub — reusable hub pattern (aggregated env,
connection lifecycle, worker supervision with backoff, service discovery).
Spec fixes: builder API drift (with_local/with_local_streaming separation),
ScopedOperationEnv → ScopedPeerEnv type name, OQ count 51→54.
Three new OQs: OQ-52 (wait_for_close), OQ-53 (backoff defaults),
OQ-54 (inbound hook placement).
