The wire records of the fleet model service, chat memory snapshots, and usage entries: plain Java with no framework type, in the package the space names them by, so a Spring AI peer and a Micronaut LangChain4j peer serve each other's model calls, resume each other's conversations, and sum usage as one fleet. Golden CBOR vectors pin the bytes. A standalone project both agentspaces-springai and agentspaces-micronaut depend on.

The fleet through LangChain4j's extension points on any JVM host: the fleet's AgentCards as a ToolProvider, discovery and data tools, a take lease renewed per model round-trip and carried across threads, chat memory in a replicated space, ...

The fleet through LangChain4j's extension points on Micronaut: the fleet's AgentCards as a ToolProvider applied to every AiService, discovery and data tools, a take lease renewed per model round-trip, chat memory in a replicated space, ...

Fleet-backed implementations of Spring AI's extension points, with one auto-configuration per feature: fleet tools, discovery and data tools, crash-safe LLM workers, FleetChatModel and ModelServer, a Spring AI embedder for semantic ...
