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

"""Unit tests for Phase 1.5 multi-platform-per-agent (relay).

Covers the agent half of Shape A (gateway-gateway D-Q1.5b.1 / D-Q1.5c):
  - relay_platform_identities() parsing the GATEWAY_RELAY_PLATFORMS list +
    GATEWAY_RELAY_BOT_IDS keyed map (the cut-over shape — no scalar fallback),
  - relay_bot_username() reading the per-platform username,
  - self_provision_relay() looping one /relay/provision POST per platform under
    one gatewayId + one secret, partial-failure-tolerant,
  - the RelayAdapter stamping the per-frame egress platform on outbound from the
    chat's inbound source.platform.

The connector HTTP is monkeypatched; the cross-repo E2E exercises the real path.
