Add alknet-core architecture specs in docs/architecture/crates/core/ with focused subdocuments for core types, endpoint, auth, and config. Write ADR-010 (ALPN Router and Endpoint) defining AlknetEndpoint, HandlerRegistry, accept loop, and graceful shutdown. Write ADR-011 (AuthContext Structure) defining AuthContext fields, immutability in handle(), and IdentityProvider injection pattern. Resolve OQ-04 (static registration), OQ-12 (file paths only for v1). Add OQ-11 (auth observability). Fix remaining alknet-secret references to alknet-vault across ADRs 003/004/005/009.

Relevant Open Questions
| OQ | Title | Status | Relevance |
|---|---|---|---|
| OQ-04 | Dynamic handler registration | resolved (start static) | HandlerRegistry is immutable at startup |
| OQ-05 | Multi-transport endpoint | open (start with quinn) | AlknetEndpoint uses quinn directly |
| OQ-11 | AuthContext resolution completeness | open | How handlers signal auth completion |
Key Design Principles
- One trait, one dispatch point:
ProtocolHandleris the only abstraction handlers implement. No StreamInterface/MessageInterface split. - ALPN does the routing: The endpoint dispatches by ALPN string. No byte-peeking, no ListenerConfig enum.
- Handlers own their wire format: Each handler manages its own protocol parsing. alknet-core provides the Connection, not the framing.
- Auth is hybrid: The endpoint provides what it can (TLS-level auth). Handlers complete what they need. AuthContext may be partial.
- WASM door preserved: BiStream is a trait, Connection is an opaque type. Core types don't assume tokio or quinn in public APIs.
