Date: Tue, 12 May 2026 14:27:39 +0300 Subject: [PATCH 02/15] feat(desktop): wire NWC wallet operations and AccountManager integration - Wire AccountManager.setNwcConnection() and clearNwcConnection() into wallet column for persistent connect/disconnect - Implement NwcPaymentHandler.getBalance() via NIP-47 get_balance RPC - Implement NwcPaymentHandler.makeInvoice() via NIP-47 make_invoice RPC - Add generic waitForGenericResponse() helper for NWC RPC operations - Auto-fetch balance on wallet column load via LaunchedEffect - Wire receive screen to generate real invoices via NWC - All wallet column

Selection + +**Goal:** Only fetch metadata for visible notes + 10-item buffer. + +**Tasks:** +- [ ] Replace the existing `LaunchedEffect(feedState, subscriptionsCoordinator)` in `FeedScreen.kt:354` with a viewport-aware version using `snapshotFlow` +- [ ] Use `lazyListState.layoutInfo.visibleItemsInfo` inside `snapshotFlow` (NOT in composition — avoids per-frame recomposition) +- [ ] Buffer ±10 items with `coerceIn(0, list.lastIndex)` to prevent IndexOutOfBounds +- [ ] Debounce at 500ms via `.debounce(500)` +- [ ] Use `collectLatest` to cancel stale fetches when scroll position changes +

+ subscriptionsCoordinator.loadMetadataBatched(authors) + // Also load reactions for visible notes + subscriptionsCoordinator.loadMetadataForNotes(viewportNotes) + } + } +} +``` + +**Key insights:** +- `snapshotFlow` reads layout info outside composition → zero recomposition cost +- `collectLatest` cancels in-flight `loadMetadataBatched` when scroll changes +- `distinctUntilChanged` skips if same indices visible after debounce +- `feedNotes` captured in `LaunchedEffect` key ensures re-launch when feed data changes + +**Files:** +- `desktopApp/.../ui/FeedScreen.kt` — replace metadata LaunchedEffect + +### Phase 2: Batched Author Subscription + +**Goal:** One relay subscription per batch instead of N individual ones. + +**Tasks:** +- [ ] Add `loadMetadataBatched(pubkeys)` to `FeedMetadataCoordinator` +- [ ] Bypass rate limiter — subscribe directly via `client.subscribe()` +- [ ] Single `Filter(kind:0, authors:pubkeys, limit:pubkeys.size)` sent to index relays +- [ ] Close subscription after EOSE from all relays (one-shot fetch) +- [ ] 5-second timeout to prevent hanging on slow relays +- [ ] Deduplicate against `queuedPubkeys` to avoid double-fetch with background path + +**Implementation pattern (relay-client + nostr-expert):** + +```kotlin +// In FeedMetadataCoordinator — follows ChessRelayFetchHelper pattern +fun loadMetadataBatched(pubkeys: List, timeoutMs: Long

insights (nostr-expert):** +- Kind 0 is replaceable — relay returns one event per pubkey, bulk lookup is efficient +- 100 authors per filter is safe for index relays (purplepag.es, profiles.nostr1.com) +- CLOSE after EOSE — transient viewport set doesn't need live updates +- No `since` on cold load — relay returns latest replaceable event regardless +- Pattern matches existing

Fast wallet responses (like get_balance) would arrive before the subscription was active, causing timeouts. Fix: subscribe first via onSubscribed callback in waitForGenericResponse, then publish. The original payInvoice wasn't affected because Lightning routing takes long enough for the subscription to be ready.

This could hang or throw. + +### H3: AES Key Regenerated Between Sessions (MEDIUM-LOW) + +The `accounts.json.enc` encryption key is stored in keychain under `account-metadata-key`. If H2 applies (keychain write fails), a NEW AES key is generated on each app launch.

This means `currentAccount()` returns null -> "No saved account". + +### H4: `cachedMetadata` Race Between Concurrent Coroutines (LOW) + +`DesktopAccountStorage.cachedMetadata` is a plain `var` with no synchronization.
