The wallet routed its ENTIRE relay.floonet.dev session (own identity, recipient
lookups, profile, catch-up, subscribe, publish) through the scoped Nym exit,
saturating its metered free-tier bandwidth so a payment gift-wrap arrived
minutes late or dropped — while nostr-sdk falsely reported "sent" (it returns on
the local mixnet-stream write, not a relay OK). Root cause was contention: ~97%
of the exit's relay bytes were non-payment overhead.
Split the nostr service into two clients:
- money client (Nym scoped exit): kind-1059 slatepacks + gift-wrap
subscribe/catch-up + recipient resolution — NIP-05 name lookup (already
mixnet via the HTTP tunnel) and the kind-10050 DM-relay lookup (moved here;
it's private payment-target resolution, and cheap). Relays kept, not dropped.
- general client (clearnet): own identity (0/10002/10050), discovery, the fat
kind-0 profile/avatar, general subs, and catch-up of non-1059.
Plus confirm-before-sent: a payment publish is not reported "sent" until a real
relay OK read-back confirms it — a slow/failed exit now surfaces as a retryable
error instead of silent money loss.
Runtime-verified: a normal session puts 0 bytes on the scoped exit (all
clearnet); a kind-1059 slatepack rides the exit and lands on relay.floonet.dev
(exit read-back + independent clearnet oracle). Exit non-payment overhead
dropped from ~50 KiB in / 164 KiB out per session to ~0.
Adds E2E test harnesses (wallet::e2e::funded_e2e_pay,
examples/nostr_split_measure, an exit publish repro in streamexit tests).
Names never affect the avatar anymore: claimed and anonymous identities
render identically (picture or pubkey-seeded gradient). Drops
gradient_avatar_ringed/name_ring/is_named and the ringed rows in the
avatar_ring example sheet.
Fire a separate high-importance system notification when an incoming
payment request (Invoice1 -> SurfaceRequest) is ingested over nostr,
mirroring the existing received-payment notification (id=2). Fail-open on
a missing JNI handle; fires once per not-yet-seen slate. No-op off Android.
Also add examples/tunnel_measure.rs, a dev harness for measuring the Nym
read tunnel (cold connect + warm per-fetch latency over the real transport).
Money path:
- Scoped, unbonded Nym exit for the money-path relay: the wallet dials a
relay operator's co-located exit over a MixnetStream (src/nym/streamexit.rs)
which pipes to its one relay; hostname-validated TLS end to end, no public
DNS. Anchor + fallback (never pin-only): any exit failure degrades to the
smolmix tunnel. relay.goblin.st's exit address is pinned in the relay pool
(src/nostr/pool.rs) and the maintainer gist so it bootstraps offline.
- STREAM_SETTLE bridges the open-before-accept gap so the first TLS byte is
not dropped into a stalled handshake.
- Verified end to end: two wallets complete a real gift-wrapped Grin payment
through relay.goblin.st over the exit, finalized + posted on mainnet
(src/wallet/e2e.rs, ignored live test).
Encryption:
- Adopt NIP-44 v3 for the NIP-17 gift-wrap path (G4): src/nostr/wrapv3.rs,
nip44 path dep; v3<->v3 and v3->v2 interop.
Also: mix-DNS (src/nym/dns.rs), full localization pass, GUI polish,
avatar-ring example, Android icon/script updates, GRIM deviation notes,
xrelay + connect-timing tests.
