Without `computeItemKey`, Virtuoso uses index-based keys so React reuses DOM nodes across pages, causing `<img>` elements to briefly flash old media before loading new sources.
Removed the newer threads banner and refresh button from catalog and board
footers. Deleted newer_threads_available translation key from all languages.
Defer useReplies to hover-only in CatalogPost. Memo CatalogRow and Post. Remove useWindowWidth and autoUpdate from CatalogPost. Replace display:none with opacity for images. Add width/height to img tags in catalog-row and comment-media. Use Virtuoso for all rendering paths (infinite, finite, pagination). Optimize filteredComments with Set lookup. Add Vite manual chunks for markdown, virtuoso, floating-ui.
FeedCacheContainer now always renders since Virtuoso is used for all feed modes (infinite scroll and pagination). Feed routes are always rendered by FeedCacheContainer; route elements are null. Outlet only renders for thread, pending, and modqueue routes. Removed clearFeeds effect. Modals lazy-loaded with Suspense fallback=null for bundle splitting.
Add static blotter snapshot, route /blotter, compact board blotter (Hide/Show All).
Include yarn blotter tooling and AGENTS rules so every changelog version has a
release line. 4chan-style table UI, subplebbit→board and plebchan→5chan in messages.
Split useReplies in post-desktop.tsx and post-mobile.tsx into preview/full modes so board cards avoid full REPLIES_PER_PAGE fetches by default. Added replies-preview-utils.ts and switched mobile backlinks to use precomputed directRepliesByParentCid map instead of per-reply useReplies.
Backend retention now keeps only recent posts, making the time filter UI
and newerThan filtering obsolete. Deleted use-time-filter hook, canonical
multiboard routes only, removed footer suggestions, dropped i18n keys.
Use useBoardFeedPageSize and useDirectoryByAddress so catalog respects
directory postsPerPage, caps feed to guiPostsPerPage * 10 in non-infinite
mode, and conditionally renders Virtuoso based on enableInfiniteScroll.
Updated Android/Electron upload paths to fail deterministically and report consistent stage details, while removing unsafe stage casting and path/package mismatches. This keeps postimages automation behavior intact and makes failures easier to diagnose.
