Merge the architecture audit refactors and follow-up UX fixes: remove release notes from generated LLM context, keep author edit controls delete-only, stabilize board refresh rendering, and address review feedback for role loading, refresh holds, moderation actions, and P2P stats polling.
* fix(thread update): refresh stale reply caches
Evict the current thread comment and known reply-page cache entries before manual refresh so stale local data does not keep replies hidden. Also defer broader multiboard suggestion feeds until the current /all time window is exhausted to reduce renderer pressure.
* fix(thread update): evict alternate reply page caches
* fix(board): hide stale time-window suggestions
* fix(board): prevent transient no threads state
* fix(board): scope raw thread fallback by sort
* fix(board): keep flash table loading during feed sync
Accessibility/semantics pass aligned with React Doctor: role-based spans/divs become real buttons, role=status becomes <output>, modals use native <dialog>, author/peer flags render as <img>, and embed/challenge iframes are sandboxed. Includes review follow-ups: correct button chrome/centering/themed dialog colors and focus rings, the missing aria-label i18n keys (all languages), the Yandex image-search URL, clearer .bso setup steps, a keyboard-accessible image-search dropdown, and removal of the post-edit ('comment edited') display (mod edits unchanged).
Apply the asymmetric viewport buffer that already fixed mobile to desktop
multiboard feeds, and trim per-post mount cost so remounts during scroll-up
are cheaper:
- Desktop multiboard buffer goes from {600,600} to {1200,2400} (top-heavy),
matching the mobile pattern from 99c0bbfac so items stay mounted longer
when scrolling back up
- Cache feed post height estimate by CID in pretext-height-estimates so
remounts skip the Pretext text-measurement work
- Memoize CommentMedia and switch its expanded-media-store reads to atomic
selectors so it stops rerendering on unrelated store changes
- Memoize useCommentMediaInfo return so its reference is stable for memo
comparators downstream
- Stop useFetchGifFirstFrame from forcing an extra render on every post
mount by bailing out of equivalent setState calls
- Extract PendingModerationActions out of PostInfo so the two
usePublishCommentModeration calls only run on the post page when
mod-approval is actually pending, not on every feed item
Board browsing, catalog filtering, post publishing, and reply publishing had little or no honest whole-repo coverage, which let route-level regressions and duplicated form side effects slip through. This pass adds targeted tests for those user flows and fixes the duplicate `PostFormTable` mounting bug they exposed.
