# rc.12 probe — agents Context Graph as distributed phonebook
# (PR #700 / feat/chain-agents-cg-phonebook, commits 499c60e9 +
# 1c99a88c + 5c3a77c7 + 1d9842aa).
#
# The new behaviour:
#   * Each node publishes its profile (agentUri + dkg:multiaddr +
#     dkg:lastSeen) into the `agents` Context Graph at startup,
#     then re-publishes on a 5 min heartbeat (AGENT_PROFILE_HEARTBEAT_MS,
#     overridable via config.network.agentProfileHeartbeatMs).
#   * PeerResolver routes dial-fallback lookups through agents-CG when
#     DHT misses (replaces the V9 RFC-04 stub).
#
# This probe verifies:
#   1. The `agents` context graph is reachable on node 1's API;
#   2. node 1's own profile lives in agents-CG with at least one
#      `dkg:multiaddr` triple (i.e. publishProfile fired);
#   3. /api/profile on every node returns a record (agent registered);
#   4. Querying node 2's agent profile from node 1's API surfaces it
#      via the phonebook (cross-node visibility).
