Every implementation returned an empty stream and nothing consumed it. Inbound arrives as OperatorMessage through HTTP/ACP, so the port is an outbound-only sink over the event log. Fixes tinyhumansai#1958
EventLog::subscribe still returns BoxStream. The test doubles in runtime/channel_tests.rs inherited that import from the parent module until ChannelAdapter::inbound was removed. Import it in the test file instead of putting the unused stream type back on the adapter.

crates/opencompany-core/src/openhuman/channel.rs:6
- Here,
messagesis broader than the documentedOperatorMessageroutes: this adapter is also used for email output, whose inbound path isInboxStore/WebhookReceived. Clarify that only operator chat usesOperatorMessage, or this module doc misstates how inbound email reaches the runtime.
//! Inbound delivery is not this port's job (issue #1958): messages arrive as
//! `CompanyEvent::OperatorMessage` through HTTP and ACP routes. openhuman-core's
//! `/events` schema is upstream-unstable and drives no control flow here.
crates/opencompany-core/src/ports/channel.rs:6
- This rustdoc now implies that all inbound messages are delivered as
OperatorMessagethrough the two operator routes, but email ingress is handled byInboxStoreand emitsWebhookReceived(and other integrations have their own paths). Please scope this wording to operator chat or mention the separate ingress paths; otherwise readers may look for non-operator inbound traffic in the wrong event variant.
//! Inbound messages do not flow through this trait. They arrive as
//! `CompanyEvent::OperatorMessage` through the HTTP chat route and the ACP
//! `session/prompt` route. The trait is an outbound-only sink over the event
//! log (issue #1958).
crates/opencompany-core/src/ports/channel.rs:17
InboundMessageremains a publicports::typesitem (and is re-exported byports::*) even though this removal leaves only its definition as an in-tree reference. That leaves an obsolete inbound-channel payload in the public surface after removing the corresponding trait method; remove or explicitly deprecate it as part of the API migration.
/// Outbound-only: there is no inbound stream. Operator and ACP messages
/// enter through the event log, not this port.
docs/spec/runtime/ports-cognition.md:217
- This backing-mechanism claim is inaccurate for the current implementations:
OperatorChannelbuffers in memory andOpenHumanChannelAdaptersends over JSON-RPC, while only some adapters use the event log. Keep the new contract outbound-only without saying every adapter is an event-log sink.
stream returned empty; the port is an outbound-only sink over the event log.
docs/spec/runtime/ports-cognition.md:217
- These lines make the same overbroad claim in the normative contract.
CompanyEvent::OperatorMessageis only for operator chat; email is filed intoInboxStoreand drivesWebhookReceived. Narrow this sentence so the port contract does not document a false universal ingress path.
Inbound messages do **not** flow through this trait (issue #1958). They
arrive as `CompanyEvent::OperatorMessage` through the HTTP chat route and
the ACP `session/prompt` route. Every implementation of the old `inbound()`
stream returned empty; the port is an outbound-only sink over the event log.

…tion note, deprecate InboundMessage - ports-cognition.md: remove 'in and out' from opening description (thread 2); split ingress section into route-specific bullets (OperatorMessage for chat, WebhookReceived for email/webhooks); drop the inaccurate 'event-log sink' characterisation (OperatorChannel/DeskChannel use the log, OpenHuman uses JSON-RPC); add explicit API migration note. - ports/channel.rs: narrow module doc to not claim all inbound is OperatorMessage; add API migration note for downstream implementers (thread 1); fix trait doc to not say messages 'enter through the event log'. - openhuman/channel.rs: clarify that this adapter covers email channels whose inbound path is InboxStore/WebhookReceived, not OperatorMessage. - ports/types.rs: mark InboundMessage #[deprecated(since="0.2.4")] — the trait method that consumed it is gone; retained to avoid a second API break.

Document the email ingress path separately.
The text maps both email and webhooks to CompanyEvent::WebhookReceived. The PR objective identifies InboxStore as a route-specific ingress path. Update this text to document InboxStore for email and CompanyEvent::WebhookReceived for webhooks, so downstream implementers do not use the wrong ingress API.

Preserve compatibility for ChannelAdapter implementors
ChannelAdapter is a public trait, and removing inbound() breaks every downstream implementation that still defines it as well as callers that invoke it. Stating that the break is intentional does not provide a migration path or prevent existing dependants from failing to compile. Retain a deprecated compatibility method, or make this an explicit major-version API break with the corresponding release and migration path.

Summary
Removes the dead
ChannelAdapter::inbound()method and its empty-streamimplementations across all channel adapters. Every in-tree implementation
returned
Box::pin(stream::empty())and nothing consumed the stream;the trait was describing a data flow the system has never had.
Inbound messages reach the runtime through route-specific paths:
CompanyEvent::OperatorMessagevia the HTTP chatroute and the ACP
session/promptroute.InboxStoreand driveCompanyEvent::WebhookReceived.ChannelAdapteris now an honest outbound-only sink.Fixes #1958
API Or Behavior Changes
Source-compatibility break for downstream
ChannelAdapterimplementers.The
inbound()method has been removed from the trait. Any out-of-treeimplementation must remove its
inbound()method; there is no replacementbecause the method was dead.
InboundMessage(inports::types) is retained to avoid a second public APIbreak. It is marked
#[deprecated(since = "0.2.4")]— downstream code shouldstop referencing it. Inbound messages arrive through
CompanyEventvariants,not this type.
No runtime behavior changes; all
inbound()implementations returned an emptystream and nothing called them.
