glm-5.2 762d9c7bd2 docs(architecture): remove removed-thing remnants from spec docs
Spec docs should describe WHAT IS, not WHAT WAS. ADRs and OQ files are
historical records by design and are left alone; the ADR-index Status
column records ADR status (stable fact). What changed in the specs:

- API code blocks no longer list removed methods. ChannelClient::connect_quic
  (channel-client.md) and CallClient::connect (client-and-adapters.md) are
  gone from the impl blocks; surrounding prose describes the current
  from_connection / spawn_dispatch primary + AlknetClient dial shape.
- Amendment (ADR-093): stream_types field is removed blockquotes dropped
  from channel-client.md and channel-operations.md (the code already
  reflects the current state).
- Historical is-removed / reversed-by / amended-by prose rewritten to
  current state across channels crate, call crate, hub, tls, core,
  endpoint, client READMEs, and the top-level README/overview.
- Dropped the EndpointError — removed subsection from endpoint/README.md
  (the type doesn't exist anymore, so it shouldn't have a subsection).
- Replaced stale connect() references in flow descriptions with the dial
  (in AlknetClient) since connect() is no longer a method.
- Removed strikethrough ADR-028 / from_jsonschema-clause rows from
  client-and-adapters.md and operation-registry.md ADR tables.
- Rewrote the ADR-066 update blockquote in operation-registry.md to
  describe FromJsonSchema's current shape.

alknet-core

Shared types, auth, config, and identity for ALPN-based protocol dispatch. Every handler crate depends on alknet-core for ProtocolHandler, Connection, AuthContext, IdentityProvider, and config types. The endpoint (AlknetEndpoint, HandlerRegistry) lives in alknet-endpoint (ADR-083 Amendment 2026-07-15); core does not carry the accept-loop runner or its transport deps (quinn, iroh, rcgen, rustls-acme). Connection::from_quinn / from_iroh are in core's types.rs as shared constructors (gated on core's quinn / iroh features).

ConnectionCredentials and RemoteIdentity live in alknet-core (per ADR-091) — the transport-level credential bundle consumed by the dial (alknet-client) and by server-side transport construction. There is no call-protocol credential bundle; auth_token is a per-request payload field on call.requested, not a transport credential.

Applicable ADRs

ADR Title Relevance
001 ALPN-Based Protocol Dispatch Core architectural model
002 ProtocolHandler Trait The trait every handler implements
003 Crate Decomposition alknet-core's position in the crate graph
004 Auth as Shared Core IdentityProvider in core
006 ALPN String Convention ALPN format, one-ALPN-per-connection
007 BiStream Type Definition Connection, BiStream trait, SendStream, RecvStream
009 One-Way Door Framework Decision classification
010 ALPN Router and Endpoint HandlerRegistry, accept loop — endpoint extracted to alknet-endpoint per ADR-083 Am. 2026-07-15
011 AuthContext Structure AuthContext fields and resolution flow
015 Privilege Model and Authority Context Per-request identity on OperationContext; admin scope for config reload
030 PeerEntry and Identity.id Decoupling authorized_fingerprints → peers: Vec<PeerEntry>; Identity.id = peer_id (stable)
031 CredentialStore Repo Trait Second repo trait in core; InMemoryCredentialStore default adapter
033 Storage Boundary and Repo/Adapter Pattern Core defines traits + in-memory defaults; persistence adapters are separate crates
065 Connection::from_stream — Generic Single-Stream Connections from_stream/from_bidi accept any AsyncRead + AsyncWrite; yield-once accept_bi contract; unblocks TCP+TLS, SSH channels, WebTransport, wasm
070 BidiStreamSource Trait — Open Connection for Extension Connection holds Box<dyn BidiStreamSource>; QUIC/iroh/stream wrap crate-private impls; from_source is the public constructor for downstream crates that implement the trait (channels, future transports)
083 Endpoint as accept-loop runner + crate extraction The endpoint is extracted from core into alknet-endpoint; core loses quinn/iroh/rcgen/rustls-acme deps; Connection::from_quinn/from_iroh stay in core as shared constructors

Relevant Open Questions

OQ Title Status Relevance
OQ-04 Dynamic handler registration resolved (start static) HandlerRegistry is immutable at startup (now in alknet-endpoint)
OQ-05 Multi-connectivity endpoint resolved (quinn + iroh) AlknetEndpoint supports both, both feature-gated (now in alknet-endpoint)
OQ-11 Handler-level auth resolution observability resolved Handlers store resolved identity on Connection; two identity scopes (connection-level for observability, per-request for ACL)
OQ-33 PeerId — logical id vs crypto identity resolved by ADR-030 PeerId = Identity.id = PeerEntry.peer_id (stable across key rotation)
OQ-34 Persistent peer registry (storage boundary) resolved by ADR-030+031+033 Core defines repo traits + in-memory defaults; persistence adapters are separate crates
OQ-35 API key asymmetry dissolved PeerEntry supports multiple credential paths; ApiKeyEntry is for tokens that ARE the identity
OQ-36 Concrete persistence adapter shapes resolved by ADR-035 Read-sync / write-async split (IdentityStore); SQLite adapter caches in memory, honker NOTIFY for no-restart cache invalidation; alknet-store-sqlite crate
OQ-37 X.509 outgoing-only case resolved by ADR-034 Three remote roles (public X.509 endpoint, transport relay, hub); PeerEntry asymmetry correct; client-side verifier by PeerEntry presence (CA vs fingerprint pin)
OQ-55 AlknetClient / Client Establishment Extraction resolved by ADR-089 The native dial seam is extracted as alknet-client — the client-side analogue of AlknetEndpoint (now in alknet-endpoint). Three dial methods (QUIC + TCP+TLS via TlsClientConfig, iroh via key).

Key Design Principles

  1. One trait, one dispatch point: ProtocolHandler is the only abstraction handlers implement. No StreamInterface/MessageInterface split.
  2. ALPN does the routing: The endpoint (in alknet-endpoint) dispatches by ALPN string. No byte-peeking, no ListenerConfig enum.
  3. Handlers own their wire format: Each handler manages its own protocol parsing. alknet-core provides the Connection, not the framing.
  4. Auth is hybrid: The endpoint provides what it can (TLS-level auth). Handlers complete what they need. AuthContext may be partial.
  5. WASM door preserved: BiStream is a trait, Connection is an opaque type. Core types don't assume tokio or quinn in public APIs.
