Task 1.2: Append-only rendering for notifications page
- Extracted buildNotificationRow(item) helper from renderNotifications()
- Added prependNotificationRow(item) with sorted insertion by created_at
- addNotificationFromEvent uses prepend when DOM has children
Task 1.3: Fix notification document.click listener leak
- Removed per-row document.addEventListener('click') that leaked on every render
- Added single delegated click listener in main() using .notif-menu-panel class
- Menu panels still close when clicking outside .notif-right
Task 1.4: Cap posts[] and postIds with rolling eviction
- Added MAX_STORED_POSTS=500 constant to feed.html and post.html
- Added prunePostsArray() that sorts, slices, rebuilds postIds/renderedPostIds
- Called in upsertFeedPost/upsertPost with +50 batch threshold
- post.html skips pruning in event mode
Task 1.5: Cap notificationsById/unreadNotificationsById with periodic pruning
- Added MAX_STORED_NOTIFICATIONS=500, MAX_POST_IMAGE_CACHE=200
- Added pruneNotificationMaps() that prunes both Maps and LRU-caps postImageCache
- Called in addNotificationFromEvent, hydrateNotificationsFromCache/Relays
Updated plan checklist marking all Phase 1 tasks complete.
prependPostCard() now inserts posts in the correct sorted position within
the existing DOM instead of falling back to a full renderFeed() rebuild
when a post is older than the first visible post. This handles relays
that deliver events out of order without wiping the feed.
Also fixed a race condition in fetchFeedWindow: the fire-and-forget
ndkFetchEvents callback was calling renderFeed() after bootstrap
completed, which wiped prepended live posts and caused concurrent
rebuild races. Now it only calls renderFeed() if the feed hasn't been
rendered yet (renderedPostIds.size === 0).
Same prependPostCard sorted-insert fix applied to post.html.
Split renderFeed() into full rebuild + prependPostCard() on both feed.html
and post.html. New live events now prepend a single card at the top of the
feed without rebuilding existing cards, eliminating O(n) DOM rebuilds on
every incoming event. DOM is trimmed to displayCount on overflow with
renderedPostIds kept in sync. Full rebuild path preserved for See More,
mute removal, bootstrap completion, and event mode.
Also added implementation checklist to plans/long-running-memory-bloat-fix.md.
Phase 1 (ndk-worker.js): Add warmOutbox, setRelayEventLogging, and getDiscoveredRelays RPC handlers. Gate broadcastRelayEvent and logRelayEvent IndexedDB writes behind relayEventLoggingEnabled flag (default off). trackRelayRead/trackRelayWrite left ungated to preserve footer activity carrots.
Phase 2 (init-ndk.mjs): Add warmOutbox, setRelayEventLogging, and getDiscoveredRelays page API exports with proper request/response wiring and timeouts.
Phase 3 (feed.html): Pre-warm outbox tracker via warmOutbox() before bootstrapFeedPosts and fetchFeedWindow calls so NDK routes author-based subscriptions to follows' write relays before short-lived fetchEvents EOSE.
Phase 4 (relays.html): Add 'Show connection history' sidenav toggle (sidenavRowToggle pattern from feed.html), gate ndkRelayEvent listener and DB loading behind connectionHistoryEnabled flag, switch live event stream to incremental DOM appending, sync state on init/beforeunload.
