Major additions:
* :proto (KMP submodule) — in-house stateful protocol replacing AG-UI.
Agent owns conversation transcript; Conversation.events(after) is a live,
replay-free stream; backfill via Conversation.getMessages(after, offset, limit).
Each Event carries an Instant date for client-side resume tracking.
Sealed hierarchies (Content/Message/Event/AgentEvent) annotated @Serializable
with snake_case @SerialName JSON discriminators so the wire format is
decoupled from Kotlin class names.
* :server (JVM, Ktor 3.1.3) — REST+SSE facade for Agent.
Public entry: Route.agentikAgent(agent, path = "/agentik").
Endpoints: create/list/get/patch/delete conversations, POST messages (202),
POST interrupt, GET messages, GET conversation events (SSE),
GET agent events (SSE), GET /health. Custom Instant serializer for
kotlin.time.Instant registered contextually on agentikJson (ISO-8601,
ignoreUnknownKeys=true, explicitNulls=false).
* :client (JVM, Ktor HTTP Client + CIO) — mirror of :server returning
a pw.binom.agentik.proto.Agent backed by HTTP calls. Custom SSE parser
since ktor-client-sse is not on the 3.1.3 client classpath.
* standalone — EchoProtoAgent (in-memory Agent for :proto), EchoAgent
(existing AG-UI echo), both mounted on the same Netty embedded server
on port 8080 (/agui and /agentik); A2A stays on its own CIO engine on
8081. EchoProtoAgent smoke-tested end-to-end against :server: all 11
endpoints, including live SSE delivery of StartResponse/AppendText/End
event triplets and Agent-level Created/Deleted events.
Design notes pinned in:
* agentik/IRC-QUESTIONS.md — closed 13-item checklist for the upcoming
:irc-server transport (channel = conversation, CTCP for structural
events, draft/chathistory for backfill, ImageStore side-channel, etc).
* docs/ARCHITECTURE.md — overall layout snapshot.
