Set IRIS_CHAT_SAME_HOST_HASHTREE=1 to let the logged-in Chat FIPS endpoint discover authenticated hashtree.blob/1 providers over fixed loopback UDP. Chat's local cache, one composite FIPS provider route, and its configured Blossom sources share the canonical hash-verifying BlobRouter. Provider misses, failures, or exit leave the other routes available, while attachment writes remain application-owned and unchanged.

Process-level integration tests may set IRIS_CHAT_FIPS_LOCAL_RENDEZVOUS_ADDR to an isolated non-zero IPv4 loopback address. Normal application runs leave it unset and use the fixed FIPS same-host rendezvous address.

Multi-device sync uses the independent Osiris and LNVPS FIPS WebSocket seeds by default. Set IRIS_FIPS_WEBSOCKET_SEED_URLS to replace them with a comma-separated list of explicit wss://.../fips URLs, or set it to an empty value for an isolated run. These are authenticated FIPS physical peers; ordinary Nostr message servers remain Nostr event and discovery/signaling relays and do not carry FIPS packets. Signed update notices use the shared nostr-pubsub path over both connected FIPS peers and configured message servers.

Primary development is on hashtree: https://git.iris.to/#/npub1399g0q2gtwjcglyjcg3jw3rcllqhm375pwases5hkvqa56aqe5wsz2eaap/iris-chat-rs
