Entry point for the estate: understands a request, consults the specialists that can settle it, composes one answer. LangGraph 1.2.11, a2a-sdk 1.1.2, both current as of August 2026. It holds no data, and the realm is what enforces that rather than the prompt. classic-models-agent-assistant is granted two optional scopes — one per specialist, plus the inference endpoint — and every domain audience it could request comes back Invalid scopes. An injection that succeeds here finds no path to a domain because there is none. "No scopes at all" was too absolute: the agent has to reason, and inference is not a domain. The two-hop token chain was the heaviest unproven thing in the design and it holds: sub stays the end user through all four hops, so their own roles apply at the far end and the MCP server filters tool discovery for the right human. azp names the last agent, not the first — Keycloak accepts actor_token and emits no act claim, so an orchestrator's identity survives only in the traces. Verified end to end: a routed question answered from the specialist's data; a question outside every remit refused rather than answered from memory; and a write proposed through the orchestrator, held by the specialist in input-required, relayed here unchanged, approved by the user through the same conversation, and written. The orchestrator never owns that decision. The graph is plan → delegate → plan, tools described by what a specialist decides rather than what it holds, delegations in one step run concurrently and capped at eight counted in calls. Rebuilt per turn, because its tools carry the user's token. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# The agent's Keycloak client secret, and nothing else. It comes from the same

# vault-keycloak rather than a store of the agents' own: this value is a
