Adds confirm-before-sent: a payment is not shown as "sent" until the relay
actually confirms receipt. If the path is slow or a send doesn't land, you now
see a clear "not confirmed — retry" instead of a false "sent" that quietly loses
the payment.
Routing is unchanged from prior builds: all wallet nostr traffic — slatepacks,
payment requests, identity, discovery, goblin.st name + relay lookups — rides
the mixnet; the grin node and price/fiat lookups stay direct.
Connect reliability, measured before release:
- Cold start: the wallet races two mixnet entry-gateway connects and takes the
first up, so a dead random draw no longer costs the full timeout (dead-round
rate drops from p to p^2; verified across 30 cold trials).
- Dead exits are condemned in ~10s instead of ~32s (fresh-tunnel probe budget
5s x 2 rounds, 4.2x margin over the worst measured healthy probe), removing
the 50-70s worst-case connects. Established-tunnel keepalive unchanged.
- "Connecting relays..." clears in ~2-4s after saving the relay list (the
Connected flag now tracks the real relay-up signal instead of waiting on a
30s catch-up fetch); identity publishes are time-boxed; the onboarding
Claim button un-gates equally sooner.
- Gateway-race and probe timings are now visible in [timing] logs.
Also: the update banner shows Goblin build numbers (not the inherited 0.3.6),
and the nip44 crate is consumed from crates.io (v0.3.0) - no sibling checkout
needed to build.
Bugfix: the mixnet exit-liveness probe now races two stable targets over two
rounds instead of a single one-shot 1.1.1.1 connect, so a healthy tunnel is no
longer false-condemned and reselected forever. Fixes the intermittent
Connecting to Nym hangs that could take minutes or never resolve (verified:
15/15 cold starts connected, zero hangs).
Also: the Android versionCode/versionName now track the Goblin build number
(were frozen at GRIM's 5 / "0.3.6"), so the OS detects upgrades correctly.
Bugfix: the default and fallback messaging relay moved from relay.goblin.st
(being retired) to relay.floonet.dev, so new installs and reconnects use the
live relay. Built-in relay fallback list updated to match.
Floonet scoped Nym exit on the money-path relay (dial a relay operator's
co-located exit over a MixnetStream, TLS end to end, no public DNS; anchor +
fallback, never pin-only), NIP-44 v3 gift wraps (G4), mix-DNS, localization,
GUI polish. Verified end to end: two wallets complete a real gift-wrapped Grin
payment over relay.goblin.st, finalized + posted on mainnet.
