glm-5.3-flash 63dc4b6d06 docs: implementation plan (TTY precedents folded in); task decomposition (17 tasks)

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

Port the dispatch spine from /workspace/@alkdev/alknet/crates/alknet-http/src/gateway/dispatch.rs to alkcall's API: GatewayDispatch::new(registry, identity_provider), invoke() (identity resolve → root OperationContext → OperationRegistry invoke → ResponseEnvelope), and invoke_streaming() (BoxStream<ResponseEnvelope> for Sub ops). The security invariants must hold identically across both: External-only (Internal → NOT_FOUND), AccessControl::check gating, no env-var reads. Port the error mapping (gateway/error.rs) too: CallError → HTTP status per docs/architecture/http-server.md §Error Mapping (NOT_FOUND→404, FORBIDDEN→401/403, INVALID_INPUT→422, TIMEOUT→504, INTERNAL→500, HTTP_<status> passthrough, retryable→Retry-After hint).

Acceptance Criteria

invoke() + invoke_streaming() ported against alkcall dispatch
Error mapping table ported with unit tests per row
Internal ops → 404 before ACL; ACL failure → 401/403 distinction preserved
cargo test passes

Notes

Agent fills during implementation.
