Quartz's RelayUrlNormalizer.isLocalHost strips literal 127.0.0.1 /
localhost / 192.168.* / .local / umbrel out of NIP-17 inbox
(kind:10050) and KeyPackage (kind:10051) relay-list events as a
privacy guard. The marmot harness was binding the loopback relay to
ws://127.0.0.1:8080, so when amy added that URL to its kind:10050 /
kind:10051 events the parser silently dropped it on read — leaving
the harness publishing to Amethyst's PUBLIC default relays
(nos.lol, nostr.mom, …) instead of the local one. Whitenoise (which
only listens on the local socket) never saw amy's KeyPackage,
breaking every Test 01–16 scenario at the first hop.
The DM harness already worked around this by using 127.0.0.2 (still
pure loopback, not on the strip list — see dm-interop-headless.sh:34).
This commit applies the same workaround to the marmot harness:
- Default RELAY_HOST=127.0.0.2 (overridable via env or --host).
- RELAY_URL is now derived from RELAY_HOST + RELAY_PORT.
- New --host flag for parity with the DM harness.
setup.sh's relay config already reads RELAY_HOST when binding
nostr-rs-relay (line 173, address = "${RELAY_HOST:-127.0.0.1}"), so
no other change is needed — the relay binds where amy is trying to
reach it.
