Adds end-to-end NIP-87 support so users can pick mints from the
network instead of having to know URLs upfront, and can publicly
endorse mints they use.
Discovery (commons + amethyst)
* commons/.../CashuMintDirectoryFilterAssembler — subscribes to
kind:38172 cashu mint announcements and kind:38000 cashu-scoped
recommendations (#k=["38172"]) on a configurable relay set.
Fedimint announcements (38173) are intentionally excluded — this
feeds the Cashu mint picker only.
* RelaySubscriptionsCoordinator.cashuMintDirectory — singleton
assembler reachable as Amethyst.instance.sources.cashuMintDirectory.
Indexing state (amethyst/model)
* CashuMintDirectoryState — account-scoped index of announcements +
recommendations. Reactive: backfills from LocalCache.notes on
first observer and listens to LocalCache.live.newEventBundles for
incremental updates. The relay subscription only runs while at
least one picker is on screen (ref-counted open()/close()).
* Ranking: follows-recommendations DESC, then total recommendations
DESC, then URL ASC. Dedup'd by (recommender, mint URL) so a
single recommender can't inflate counts by re-posting.
* CashuMintDirectoryEntry — display model with URL, latest
announcement, total and follows-recommendation counts.
Publishing recommendations (CashuWalletOps)
* recommendMint(mintUrl, dTag?, review) — publishes kind:38000 with
both the `a`-tag (pointing at the mint's announcement by
kind:pubkey:dTag) and a `u`-tag with the raw URL so older clients
indexing by URL still pick it up.
UI integration
* MintPickerSheet — ModalBottomSheet with search field + scrollable
list. Each row shows the mint name (parsed from the announcement
content) or URL, with badge chips for "from people you follow"
and total recommendation counts. The "Add" button writes the URL
back to the caller's mints list; already-added URLs show "Added"
instead.
* AddCashuWalletScreen gets a "Browse" button next to the Mints
section header that opens the picker. Selected mints are still
Verify-able via the existing ping; users can still paste manually
if they want.
* CashuWalletScreen's mint list gets a thumb-up icon button per
mint that fires viewModel.recommendMint(url) — best-effort,
silent failure (logged via Log.w("CashuWallet")).
Wiring
* cashuMintDirectoryFilterAssembler factory plumbs through Account →
AccountCacheState → AppModules. The mock test AccountViewModel
constructions in AccountViewModel.kt are updated to pass a fresh
assembler.
playDebug + fdroidDebug compile clean. 24/24 jvm tests still passing.
