The public API and SPI: the Space interface and template DSL, leases, entry records, the advertisement family, and the extension points implementations plug into. Applications program against this module; implementation modules stay swappable.

Testing utilities shared by all modules and by applications: a mutable TestClock, the SimNetwork deterministic in-memory transport fabric with partition control, and common test fixtures.

Layer 0 of the spec: Ed25519 peer identity with keystore persistence, PeerID derivation, message signing and verification, and advertisement signing.

Layer 1 of the spec: signed CBOR wire envelopes, peer nodes with per-group runtimes, leased membership with SWIM-style ping and indirect ping-req, the two-channel gossip bus (rumor plus anti-entropy), and the TCP reference transport.

Layer 3 of the spec: the AgentSpace tuple space. Ships LocalSpace, a complete single-JVM implementation of the Space API with leases and notifications, plus the delta-CRDT core (OR-Set entry state, LWW lease registers) on which the ...

Layer 2 of the spec: the signature-verifying, TTL-evicting advertisement cache fed by gossip, local-first find, and hop-budgeted remote queries.

The framework-neutral annotation model and binder: @SpaceTake, @SpaceNotify, and @BidFunction on plain objects, virtual-thread worker loops with crash-equals-lease-lapse semantics, and automatic AgentCards generated from annotations and ...

The OidcAuthorizer (security remediation plan §6): privileged-operation authorization deferred to JWT scopes minted by the organization's identity provider, validated with Nimbus JOSE+JWT against a cached JWKS. Optional: fleets on the ...

Layer 4 of the spec: the capability-service runtime (publish, refresh, and discover CapabilityAdvertisements) and the shipped capabilities: push-sum aggregate, vote, the ordered-log (Raft) coordinator behind ORDERED takes, ...

Translates AgentSpaces AgentCards to A2A agent cards and serves them over HTTP, so A2A clients can discover a fleet's agents through one gateway.

The fleet console as a served surface: a read-only observability peer presenting membership, discovery, and space state over HTTP. A HAL+JSON API (application/hal+json links, Spring HATEOAS compatible), a Server-Sent Events activity ...
