hermes-agent/tests/gateway/relay/test_relay_policy_send.py

"""Unit tests for the gateway-side relay relevance-policy declaration (Phase 6 ζ).

Covers gateway.relay.relay_relevance_policy() (the projection of the agent's
mention-gating / free-response / allow-bots config into the connector's generic
vocabulary) and send_relay_policy() (the boot-time POST to /relay/policy). The
connector HTTP POST is monkeypatched; the cross-repo E2E (connector repo,
gateway_policy_driver.py) exercises the real route. These prove the PROJECTION
mapping, the auth/skip logic, and the fail-soft boot behaviour.
