The to_mcp test helper full_registry_with_ops always registered ops
with HandlerKind::Once(make_echo_handler()) regardless of op_type.
When the search_returns_access_control_filtered_ops_excluding_subscriptions
test passed OperationType::Subscription for "events/stream", the
registry's kind validation (tightened in commit 9c81129, ADR-049)
rejected it with "handler kind mismatch: Subscription requires
HandlerKind::Stream (got HandlerKind::Once)" — panicking in
register().unwrap() before the test could run.
This was a pre-existing test-helper bug (predates Phase 6; verified by
stashing Phase 6 and reproducing on the develop baseline) but it
blocked Phase 9's 'Done when' criterion (cargo test -p alknet-http
passes).
Fix: added a handler_kind_for(op_type) helper that branches on op_type
(HandlerKind::Stream(make_echo_streaming_handler()) for Subscription,
HandlerKind::Once(make_echo_handler()) for Query/Mutation) and used
it in both register loops of full_registry_with_ops. The streaming
echo handler yields the input back as a single call.responded frame —
sufficient because the test only verifies that the MCP search tool
*excludes* Subscription ops from its listing; it never invokes the
handler.
Result: cargo test --workspace --all-features is fully green (1008
tests, 0 failures). Phase 9's 'Done when' criterion is met. The
findings doc's Phase 9 entry is updated to record the fix.
Closes Phase 9.
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
