Three tasks implementing ADR-027:
1. core/rawkey-decouple-from-iroh: TlsIdentity::RawKey now uses
Ed25519SecretKey (alknet-core-owned wrapper over ed25519_dalek)
instead of iroh::SecretKey. RawKeyCertResolver and Ed25519SigningKey
un-gated from #[cfg(all(quinn, iroh))] to #[cfg(quinn)] only.
Quinn-only builds (default) now support RFC 7250 raw-key identity.
iroh transport converts via iroh::SecretKey::from_bytes.
2. core/endpoint-request-client-cert: replaced with_no_client_auth()
with AcceptAnyCertVerifier — a custom ClientCertVerifier that
requests client certs but doesn't require them or verify against
a CA. alknet's identity model is fingerprint-based (the
authorized_fingerprints set is the trust anchor), not PKI-based.
Peer certs are extracted at the TLS layer for fingerprinting;
peers without certs connect normally.
3. core/acme-integration: TlsIdentity::Acme variant (domains,
cache_dir, directory, contact) + AcmeDirectory enum. TlsSetup
two-phase construction: synchronous for X509/RawKey/SelfSigned,
async for Acme (spawns AcmeState event loop, builds ServerConfig
with ResolvesServerCertAcme). acme-tls/1 ALPN added when ACME is
active; dispatch_quinn guard closes challenge connections
gracefully (challenge is TLS-layer-handled). acme feature gate
keeps rustls-acme out of non-ACME builds.
Workspace: build/test/clippy green across all 3 feature configs
(quinn-only, quinn+iroh, quinn+acme, all-features). 331 tests, 0
failures, 0 warnings.
W1 (call/protocol/abort-cascade-wiring): wire AbortCascade into
CallAdapter handle_stream for EVENT_ABORTED. Cascades with
AbortPolicy::AbortDependents, aborts root, no descendant frames on
wire (ADR-016 Decision 2). Two integration tests added.
W2 (core/endpoint-client-fingerprint): extract TLS client cert
fingerprint in dispatch_quinn (SHA256:<hex> of leaf cert DER via
peer_identity) and dispatch_iroh (ed25519:<hex> of peer NodeId).
Fingerprint format documented in auth.md. Server config change
(with_no_client_auth → request-but-don't-require) deferred to new
follow-up task core/endpoint-request-client-cert.
W3 (vault/mnemonic-debug-redaction): replace Mnemonic derive(Debug)
with manual redacting impl (phrase: "[REDACTED]"). Seed confirmed
no Debug impl. Redaction test added.
W4 (core/auth-apikey-resources): Option B — drop entry.resources from
spec. External identities (token/fingerprint) grant scopes only;
resource-scoped ACLs are composition-internal (ADR-015/022). auth.md
corrected + limitation documented. Two tests confirm empty resources.
review-post-impl-fixes: all 4 verified, workspace green (326 tests,
0 failures, 0 clippy warnings). Review #004 status → resolved.
Graph: 34 tasks, 12 gens.
