Browser tests: public relays answered in the page, never reached

2026-10-07T19:02:51Z

A suite run let ~90 throwaway test wallets subscribe and publish on public relays from one home address, and nos.lol and relay.damus.io banned it. tools/puppeteer.js wraps puppeteer-core: every socket to a non-local host gets an in-page stand-in relay (EVENT -> OK, REQ -> EOSE). Tests that read real content launch with { relays: 'read' } (real reads, publishes answered in place); feed-live, chat-layout and cordn-ui launch with { relays: 'live' }. LIVE_RELAYS=read|1|host,... overrides per run. profile-key-qr: measure the QR again if a repaint swapped it out. Co-Authored-By: Claude Opus 5.5

Feed tests: open the Feed from the bottom nav, on Following

2026-10-07T15:34:45Z

The feed left the chat home for a bottom-nav tab, and a wallet with no feed remembered opens on Popular, so these tests click the Feed tab and seed Following as the wallet's last feed. Also brought up to date: - feed-live: the pill lands on the oldest new post; arrivals at the top go in above the first post (held still), not behind the pill; scroll up a screen at a time (one jump lands before the windowed rows are back) - feed-custom: only the feeds' chips are counted (not All/Images/…); the follows box is not the first checkbox any more; the last feed is remembered across a reload; the pack shows in the feed's editor (the chat home no longer lists the feed) - feed-follow: Feed tab + Following chip instead of the messages-home row; the feed opens at ten posts (tall ones, so a page doesn't fill the screen) - moderation: nos.lol is a local stand-in (a relay that won't connect held the mute list back past the checks) Co-Authored-By: Claude Opus 5.5

Feed: the foot says when older posts are loading, and when there are none left.

Feed: only the rows near the viewport are in the DOM, however far you scroll.

2026-09-26T14:31:09Z

A long scroll left hundreds of rows mounted, and every repaint (a zap count, a profile landing, the thirty-second sync) rebuilt and diffed all of them — the slowdown deep in the feed. Rows beyond two and a half screens either side of the viewport are now replaced by a spacer at their measured height, so the page keeps its length (scrollbar, Back, arrival anchoring behave as before) while a repaint touches a few dozen rows. After svelte-virtual-list: measure after paint, estimate unmeasured rows at the running average, hold the reader's row still when a measurement corrects an estimate. Applies to the profile notes list too. Tests: feed-window-dom (120 posts, 27,800px page, 12–24 rows mounted, anchor held, spacers both sides); feed-live looks at the top after scrolling up; the moderation test's stub relay no longer lets real posts in.
