onemessagebus-agent

The agent profile over the onemessagebus core: the vocabulary the agent stack shares, declared once here and re-exported by every consumer.

• Source::{Agentgraph, Vcs, Pipeline} — the three producers, and the envelope version each writes against (pipeline 2, the others 1).
• Phase::{Development, Integrate, Review, Release} — the reserved top-level dimension, omitted from the wire when absent.
• Labels — run_id, round, node, step, member, persona, plus a flattened map of free-form extras.
• Envelope, EventFilter, Matcher, Emitter, Reader, Merge — the core's generic types over this vocabulary, serializing to the bytes oneagentgraph, onevcs and onepipeline write today.
• registry() — every schema the stack registers: agent.event-envelope at [2, 1], agent.reply-envelope at [3, 2], and the artifact reference, the filter and the labels (agent.artifact-ref, agent.event-filter, agent.labels) at 1.

use onemessagebus_agent::{Emitter, Labels, Phase, Source};
use serde_json::Map;

let emitter = Emitter::new("s-1", Source::Vcs, Box::new(std::io::stdout()))
    .with_labels(Labels { run_id: Some("R".into()), ..Labels::default() })
    .with_dimensions(Phase::Development.into());
let envelope = emitter.emit("push", Map::new());
assert_eq!(envelope.v, 1);
