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 `POST /publish` per ADR-068: NDJSON request body (each line =
|
|
one published chunk) dispatched through `invoke_sink()` (alkcall
|
|
ADR-046); handler's final ResponseEnvelope → 200 JSON or mapped error
|
|
status. Resolve OQ-02 during this task: first line carries
|
|
`{ "operation": "/{service}/{op}", "chunk": {...} }` (subsequent lines
|
|
`chunk`-only); terminal errors are plain HTTP status + JSON body (not
|
|
an NDJSON line). Client disconnect drops the body stream → sink
|
|
cancelled (PublishStream sees EOF). Non-Pub target → 400
|
|
INVALID_OPERATION_TYPE. Tests: multi-chunk publish round-trip against a
|
|
SinkHandler over DuplexStream, early-disconnect, error mapping.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] /publish wired; OQ-02 convention implemented and documented in ADR-068
|
|
- [ ] Sink round-trip test (3+ chunks → final envelope)
|
|
- [ ] Disconnect mid-stream cancels the handler (no hang)
|
|
- [ ] to_openapi gateway doc gains /publish; gateway `info.version` minor bump
|
|
- [ ] `cargo test` passes
