A consistency review of the alknet-http specs found two classes of
issues: internal contradictions from the mid-spec pivot (the to_openapi
gateway pattern landed in prose but not in cross-references), and a
systematic client→server assumption that only holds for the OpenAPI/MCP
case leaking into the WebTransport architecture.
Class 1 (internal contradictions):
- C1: to_openapi was half-refactored — body described the ADR-042
gateway pattern but the decisions table and ADR-036 still said
'paths mirror /{service}/{op}'. ADR-036's to_openapi clause is now
amended as superseded by ADR-042; the stale decisions row and README
Principle 2 are fixed.
- C2: the axum Router route list didn't include the 5 gateway endpoints
(/search, /schema, /call, /batch, /subscribe). Added them; clarified
/openapi.json as the gateway description doc; added gateway paths to
the decoy exclusion list.
- C3: ADR-034 §5 still talked about the 'h3/WebTransport deferral
bucket' that ADR-038 eliminated. Amended §5/Consequences/References
to drop the deferral framing (the auth-model decision stands; only
the 'when' wording was stale).
Class 2 (one-way direction assumption):
- C4/C5/C6: the WebTransport specs framed the session as browser→hub
one-way, when the call protocol is bidirectional and WebTransport is
a general ALPN transport substrate. New ADR-043 reframes WebTransport
as a bidirectional ALPN transport substrate (call protocol is the
first/canonical target; needs no WASM parser), names the call
protocol's bidirectionality over WebTransport sessions, and states
the inbound no-PeerId connection-local overlay as the mirror of
ADR-034 §2. webtransport.md is updated to reflect this framing;
ADR-040 is repositioned (not superseded) as the substrate's non-call-
ALPN mechanism.
- C7: the HTTP/1.1+HTTP/2 surface's one-directionality is now named as
a lossy consequence of HTTP request/response; WebTransport is named
as the surface that restores the bidirectional call model.
- C8: overview.md acknowledges the from/to direction model is
OpenAPI/MCP-specific, not a call-protocol property.
A review subagent pass on ADR-043 + webtransport.md found no critical
issues; warnings W1-W3 (residual browser-as-subject framing, ADR-009
rationale in spec, opening abstract tone) and suggestions S2/S4/S5
were addressed.
