ADR-027 resolves the architectural gap surfaced when ACME integration
became a concrete target:
1. TlsIdentity::Acme variant — static config data (domains, cache_dir,
directory, contact) with async AcmeState constructed at endpoint
setup via two-phase TlsSetup (not stuffed into the Clone-able enum).
2. TlsIdentity::RawKey decoupled from the iroh feature — uses
Ed25519SecretKey (alknet-core-owned wrapper over ed25519_dalek)
instead of iroh::SecretKey. Raw-key TLS identity (RFC 7250, the
default for most alknet nodes) now works in quinn-only builds.
iroh transport converts via SecretKey::from_bytes.
3. ACME feature-gated behind new acme feature (rustls-acme optional
dep). Non-ACME builds don't compile it.
4. dispatch_quinn guard for acme-tls/1 challenge connections — TLS-ALPN-01
is handled at the rustls cert resolver layer during the handshake;
the guard closes challenge connections gracefully instead of logging
a misleading "no handler" warning.
Research confirmed QUIC (quinn) handles ACME challenges differently than
TCP (reverse-proxy): quinn gives no ClientHello peek hook, but the
challenge is fully answered at the cert resolution step before the
connection surfaces to the application. No handler registration needed.
Spec updates: config.md, endpoint.md, open-questions.md (OQ-12),
overview.md + README.md (ADR index), ADR-010 (cross-ref).
Tasks: core/rawkey-decouple-from-iroh (gen 1, no deps),
core/acme-integration (gen 2, depends on rawkey). Graph: 36 tasks.
Governance (Tier 2):
- Advance ADR-022 and ADR-023 from Proposed to Accepted (specs already
depend on their types as source of truth)
- Amend ADR-015: mark Decision 3 and Assumption 6 as superseded by ADR-022;
update handler_identity type to CompositionAuthority
- Amend ADR-002: note handle() signature revised by ADR-007 (BiStream → Connection)
- Amend ADR-004: note 'enrich/replace' AuthContext language superseded by
ADR-011's immutability model; update to describe set_identity on Connection
- Update main README ADR table to show ADR-022/023 as Accepted
Spec-ADR consistency (Tier 3):
- Add abort_policy: AbortPolicy field to OperationContext struct (ADR-016
Decision 6 mandated this but the spec omitted it)
- Define AbortPolicy enum (AbortDependents | ContinueRunning) with Default impl
- Add abort_policy to build_root_context and LocalOperationEnv::invoke()
- Define the OperationEnv trait explicitly with invoke() and
invoke_with_policy() methods (was referenced as 'must remain a trait'
but never defined)
- Specify From<StreamError> for HandlerError impl with exact variant mapping
- Add Connection::from_quinn() / from_iroh() constructors (was referenced
as Connection::new() but never defined)
- Remove undefined CertAuthorityEntry placeholder from AuthPolicy v1 (will
be added additively when alknet-ssh lands)
- Fix config.md key-differences table: rate limits are in DynamicConfig,
not StaticConfig
Mechanical fixes (Tier 1):
- overview.md: 'closes the QUIC stream' → 'closes the connection' (stale
from pre-ADR-007 model)
- overview.md: OQ-04 entry updated from stale 'defer to implementation'
to 'resolved: static at startup'
- mnemonic-derivation.md: remove duplicate helper functions block (incomplete
first copy, complete second copy)
- ADR-003: add iroh (feature-gated) to alknet-core dependency list, added
by ADR-010
- ADR-021: fix ambiguous 'W1 drift issue from the vault review' cross-reference
- ADR-022: rephrase FromCall 'leaf locally' to 'leaf in the local registry'
- ADR-017: add error_schemas to from_call mirror list and services/schema
step (inconsistency with ADR-023)
- ADR-016: fix self-referential citation ('ADR-016 Assumption 5' → 'Assumption 5')
- Add ScopedOperationEnv::empty(), allows(), new() and
CompositionAuthority::none(), new() impl blocks (referenced but undefined)
- Add call.completed clarification for non-subscription calls
- Add services/schema leading-slash normalization note
- Crate README ADR tables: add missing ADR-013 (call), ADR-015 (core),
ADR-006 + ADR-010 (vault)
- Vault README: add consolidated 'Known Source Drift' table tracking all
four drift items (OsRng, unwrap, CURRENT_KEY_VERSION, spawn bug) in one
place, including the two previously missing from README
- Rewrite OQ-12: separate two distinct TLS identity use cases (RFC 7250
raw keys as default for P2P, X.509 for domain-hosted/browsers) instead
of conflating them as 'file paths now, ACME later'. ACME is a proven
pattern from the reverse-proxy project, not speculative future work.
- Resolve OQ-13 and OQ-14: remove 'Phase 1' framing from core crate
specs. /{service}/{op} is the correct design for alknet-call, not a
simplification. Batch as correlated call.requested events is the correct
protocol design. Core crates need to be done right from the start.
- Add ADR-013: Rust as canonical implementation language. TypeScript
@alkdev/operations is a reference that informed the design, not a
parallel implementation. The only JS use case is browser SDK adaptation.
Five reasons: memory safety, LLM competence, supply chain attacks,
performance, browser-only JS.
- Add alknet-agent crate to the crate graph (depends on alknet-call, not
alknet-core). Agent service uses call protocol client for tool dispatch
and vault/derive for provider keys — no env vars for secrets. ALPN
alknet/agent added to the registry.
- Add OQ-15: call protocol client and adapter contract. alknet-call needs
both server (CallAdapter) and client (remote invocation over QUIC), plus
the adapter traits (from_*, to_*) that enable composition.
- Clarify alknet-napi as thin NAPI projection layer, not business logic.
- Fix bugs: ProtocolController → ProtocolHandler typo, OperationEnv
invoke() path format inconsistency, RateLimitConfig comment confusion.
- Update endpoint.md TLS section: comprehensive identity model comparison
table, RFC 7250 as default mode, ACME as proven pattern.
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.
