operation-registry.md: - OperationSpec gains resource_id_path: Option<String> (JSON pointer into the input for runtime-spawned resource ID extraction) - AccessControl::check signature updated: consults an OwnershipProvider for dynamic resource ownership; falls back to static Identity.resources when no provider is wired (backward compatible) - Dispatch flow updated: step 3 extracts resource_id via spec.resource_id_path before the ACL check - Added composition + dynamic ownership interaction (ADR-050 §4d): two orthogonal checks, ADR-015/022 unchanged - Design Decisions table + Open Questions + References updated auth.md: - New 'Ownership Provider and Store (ADR-050)' section: OwnershipProvider (sync read trait) + OwnershipStore (async write trait) + InMemoryOwnershipStore default adapter; fourth instance of the repo/adapter pattern (ADR-033) - How it integrates with AccessControl::check - Access pattern: proxy-only (spawner owns, proxy to share, teardown revokes; no grant mechanism in core) - Per-node ownership (no cross-node propagation in the base model) - Resource-scoped ACLs table gains the dynamic ownership path - Design Decisions table + Open Questions updated

| 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 | Endpoint, HandlerRegistry, accept loop |
| 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 |
Relevant Open Questions
| OQ | Title | Status | Relevance |
|---|---|---|---|
| OQ-04 | Dynamic handler registration | resolved (start static) | HandlerRegistry is immutable at startup |
| OQ-05 | Multi-connectivity endpoint | resolved (quinn + iroh) | AlknetEndpoint supports both, both feature-gated |
| 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 | 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) |
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.
