coinosv3.git/tools/feed-video-aspect-test.js, branch master

Feed videos before they play: the picture fills the box with only the play button and size (no seek bar or sound button until playing); hovering the cover no longer paints it over with the app's button grey; upright phone clips (stored sideways with a quarter-turn matrix) paint upright, v1 size caches dropped; a clip the probe found HEVC switches to the copy before fetching the original

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

Rebuildable caches move from localStorage to IndexedDB (cache-store.js)

2026-10-07T14:24:33Z

localStorage is ~5M characters per site whatever the device, and a phone had filled it. Profiles, faceless list, reports, follow packs, profile pages, relay lists, the moderation baseline, community directory, link previews, video sizes/probes and search profiles (~3M on that phone) now live in IndexedDB, which shares the site's disk allowance (GBs). cacheStorage keeps localStorage's string API: reads from memory, coalesced write-behind, flushed on hide. Copies migrate on open and are removed once written. Boot waits for it (max 3s) beside the Ark store; caches read at construction re-merge on ready; an early write can't replace the stored copy. A copy an older build writes to localStorage later moves in on first ask. Wallet wipes reach it; private mode stays on localStorage. Read markers, drafts, follows, note threads and sync outboxes stay in localStorage on purpose (cross-tab consistency, early server-rendered seeding). Also asks navigator.storage.persist().

The feed you were on is remembered per wallet; new ones start on Popular

2026-10-02T21:46:32Z

It was one device-wide key, so a new account opened on whatever the last one was reading (#gardenstr: the starter feed has the same id in every account). Now keyed by the wallet, re-read when a wallet opens (the feature outlives a sign-out), Popular when nothing is remembered, and the old device-wide key is dropped. A feed opened from a link stays put. Co-Authored-By: Claude Opus 5.5 Claude-Session: https://claude.ai/code/session_01Dmcrt9KyNDKVWFKnb8BREo

Pictures paint with the page: column-sized copies, and CORS that works

2026-10-02T17:09:28Z

Measured in the live tab (screencast frames): back from a profile, the feed's text was on screen ~200ms before its photo. The was loaded and complete on the first frame — a 3024px, 12-megapixel original that Chrome re-decodes whenever the page is rebuilt. - Post photos wider than the column at 2x are painted from an 1100px WebP copy made once (fetch, createImageBitmap, OffscreenCanvas) and kept in Cache Storage; it decodes in a few ms, decoding=sync, inside the same frame as the text. GIFs and small pictures keep the original; the lightbox opens the original. Profile banners use the same copies, warmed on prefetch. - corsFetch: primal's CDN caches its no-Origin answer without Vary: Origin, so a CORS fetch after the got that header-less copy and failed — which had written blossom.primal.net, m.primal.net and coinos.io off as 'no CORS', so their avatars never got local thumbnails and painted late from the originals. A refusal is now retried once past the cache before a host is blamed; the old list is dropped (nocors-v2). - DM list: the unread dot sits centred at the row's end, like the communities' below, instead of beside the time. - Balance card gear: the icon alone, no circle.

Tall videos fill the column with no side bars, up to the screen's height

A video in the feed paints at its own shape, not a 16:9 frame with black bands beside a portrait clip.

2026-10-01T01:36:29Z

The shape comes from the post's imeta dim when it gives one (Amethyst, Primal and others publish it), else from the clip's metadata fetched while the row warms (3 s cap), and is remembered on the device. The box is as wide as the column, never taller than 75vh; an unknown shape keeps 16:9. tools/feed-video-aspect-test.js: 3:4 and 16:9 clips measured ahead, a 9:16 one shaped by imeta alone (its file served too late to probe), a broken one.
