iroh uses RFC 7250 raw Ed25519 public keys for TLS instead of X.509
certificates. rustls already supports this. This means the quinn
endpoint can also use raw public keys — same key-based identity model
as iroh, but with direct QUIC over UDP. X.509 is optional, needed
only for domain-facing identity (browser/WebTransport clients).
Update StaticConfig with TlsIdentity enum (X509, RawKey, SelfSigned)
and add iroh_relay field. Remove 'iroh deferred' language — iroh is
a first-class connectivity mode.
iroh's Endpoint natively supports ALPN negotiation and set_alpns(). Our
HandlerRegistry dispatches exactly like iroh's own ProtocolMap/Router
pattern, but shared across both quinn and iroh connection sources. We
use iroh::Endpoint directly (not iroh::Router) because our HandlerRegistry
and AuthContext are shared across sources.
Correct the conflation of quinn/TLS/iroh as interchangeable transports.
They are complementary connectivity modes serving different deployment
contexts: quinn (public IP + TLS), iroh (NAT traversal via relay), TCP
(handler-specific, not core). Clarify that TLS cert = network identity,
not auth identity. Map stealth mode to HTTP handler on standard ALPNs
instead of byte-peeking. Resolve OQ-05 as one-way door. SendStream/
RecvStream now use internal enum dispatch for both quinn and iroh
streams.
