Conventions satisfied, `cargo doc` clean, no actively-wrong comments,
producer/consumer naming consistent in the call/registry docs.
P-10 — `pump_sink` matched the string literals "call.published",
"call.completed", "call.aborted" (dispatch.rs) instead of the
EVENT_PUBLISHED / EVENT_COMPLETED / EVENT_ABORTED constants the rest
of the file imports. Replaced with the constants — pure refactor
hazard, no behavior change.
C-20 remainder — the wrong "SAFETY:" comment at from_call.rs:271
marked no `unsafe` block and was factually wrong (described a `'static`
return that isn't what `derive_alpn_from_op_name` does — it returns
`Option<String>`; the leak happens in `leak_alpn`). Reworded to a
plain note about the `'static` lifetime requirement. Also reworded
the abort-cancels claims in the `pump_sink` and `pump_stream` doc
comments (dispatch.rs): both claimed `call.aborted` "cancels the task
and drops the handler future" — the handler is actually `join!`-ed to
completion and not yet cancelled (the abort-cancels-Pub mechanism is
review 001 Unit 9). Trimmed step-numbered narration comments in
adapter.rs / client.rs that restated what the code does, keeping the
ordering-constraint and REQ-CH comments. The big reassembly.rs
deliberation landed with Unit 4; this finishes the remainder.
C-09 — fixed the 2 remaining `cargo doc` warnings (was 4; the
register_openable links were fixed in Unit 3):
- `unresolved link to default_policy` (operations.rs:50) — the
[`default_policy`] intra-doc link resolves to
super::policy::default_policy; used the full path.
- `env is both a module and a macro` (channels/mod.rs:30) — the
[`env`] link collided with the std `env!` macro; qualified as
[`self::env`].
`cargo doc --no-deps` now emits 0 warnings.
C-22 remainder — removed the filler `PhantomData` test at client.rs
(`let _ = std::marker::PhantomData::<ChannelClient>;` — asserts
nothing). The env.rs tautology was already removed in Unit 3.
C-24 — replaced "client→server streaming" with "producer→consumer
streaming" in call-protocol.md, operation-registry.md, README.md, and
open-questions.md (4 occurrences). Per AGENTS.md §8 the convention is
producer/consumer, not server/client. The remaining "client→server"
references in channels ADRs 034/037 are in stream_type table contexts
that Unit 10 (C-26) will handle as part of the spec-doc renumbering.
P-11 — amended ADR-046 §3's SinkHandler type so the stream item type
matches §6. §3 declared `Pin<Box<dyn Stream<Item = Value> + Send>>`;
§6 declared `Pin<Box<dyn Stream<Item = Result<Value, CallError>> +
Send>>`. The code uses §6's shape uniformly (registration.rs:32-40,
aliased as PublishStream). §3's text and the Door-type section are
amended to match §6; the Door-type section already marked the concrete
stream item type a two-way-door detail, so this is a text correction,
not a design change. Added an amendment note dated 2026-08-13.
Verification:
- cargo test --lib → 449 passed, 0 failed (was 450; -1 removed filler test)
- cargo clippy --all-targets -- -D warnings → clean
- cargo fmt --check → clean
- cargo doc --no-deps → 0 warnings (was 2)
The call protocol had Subscription (server→client streaming) but lacked
the directional complement: client→server streaming, where the initiator
produces a stream and the responder's handler consumes it. This gap was
inherited from the @alkdev/pubsub EventEnvelope prior art, which has
subscribe but no wire-level publish.
ADR-046 adds the Pub primitive:
- OperationType::Pub (client→server streaming)
- OperationType::Subscription renamed to Sub (wire: "subscription" → "sub")
- SinkHandler type + HandlerKind::Sink variant
- PublishStream type alias (Stream<Item = Result<Value, CallError>>)
- OperationRegistry::invoke_sink() dispatch path
- call.published wire event (sixth event type, additive)
- OperationSpec.publish_schema (Option<Value>, validates per-chunk input)
- DispatchResult::Sink + SinkDispatch (handler future + chunk channel)
- Dispatcher::pump_sink (feeds call.published chunks from wire to handler)
- CallConnection::publish() / publish_with_payload() client methods
- from_call sink forwarding handler (make_sink_forwarding_handler)
- make_sink_handler() helper
Fan-out/broker (one producer, N consumers, topic matching) is deferred to
the channels session — the call protocol is point-to-point; the broker is
a routing concern that sits above it. The Pub primitive is the
load-bearing piece the broker will compose on.
