Two federated-room bugs surfaced by the desktop build:
1. markAsRead only sent one unthreaded receipt at the main-timeline tail. With
threadSupport enabled, thread replies leave the main timeline, so a reply
newer than that tail was never covered — its per-thread notification count
(which the room dot sums) lingered, so the unread dot never cleared even
after reading. It also early-returned when the main timeline was already
read. Now also send a threaded receipt at each unread thread's latest reply.
2. useAvatarDecoration never cached non-404 failures, so every avatar mount
re-requested io.lotus.avatar_decoration for federated users whose homeserver
403s/502s the field — a refetch storm that spammed the console and hammered
our homeserver's federation. Now cache definitive rejections (400/403/404)
and give up after ~2 transient (429/5xx) attempts per session.
Gates: tsc/eslint/prettier clean, build OK, 665 tests.

Avatar decorations: useAvatarDecoration cached ALL profile-field fetch
failures as "no decoration" permanently for the session. The member list
and timeline mount many avatars at once, so one rate-limited (429) burst
would wipe everyone's decoration until a full reload. Now only a genuine
404 (field unset) is cached; transient errors retry on the next mount.
Saved Messages panel — full redesign to match the canonical MembersDrawer:
- co-located BookmarksPanel.css.ts: toRem(266) + max-width:750px full-screen
media query, replacing the old position:absolute/zIndex:100 mobile "modal"
that had no backdrop or escape
- variant="Background" header; room avatars on each item (was a generic hash)
- priority tokens replace all raw opacity hacks; 3px borderLeft accent removed
- Escape-to-close; multi-line preview is now a proper folds Button (N38)
Media Gallery (N12): moved fixed positioning + width into MediaGallery.css.ts
using toRem(320) + a full-screen media query; border/header use config tokens;
added Escape-to-close on the panel (previously only the lightbox handled it).
Presence (SettingsTab / useUserPresence):
- N16: wrap presence-dot trigger in TooltipProvider; replace undefined
--bg-surface with color.Background.Container
- N17: add escapeDeactivates + isKeyForward/isKeyBackward to the FocusTrap
- N19: align reader labels (usePresenceLabel) to the setter vocabulary
(Online/Idle/Offline) so a chosen status matches the tooltip others see

256×256 APNG overlays from avatardecoration.com (open CORS CDN).
Stored in the user's Matrix profile as io.lotus.avatar_decoration via
MSC4133 so all Lotus Chat users see each other's decorations.
- avatarDecorations.ts: curated catalog of 110 original-IP decorations
across 9 categories (Gaming, Cyber, Space, Fantasy, Elements,
Japanese, Nature, Spooky, Cozy)
- useAvatarDecoration: per-user profile fetch with module-level cache
and in-flight deduplication so concurrent renders for the same userId
share one HTTP request
- AvatarDecoration: position:relative wrapper that overlays the APNG
8px beyond the avatar on all sides; renders nothing when no decoration
is set (zero cost for undecorated users)
- ProfileDecoration: scrollable grid picker in Settings → Profile,
grouped by category with live preview; Save button appears only when
the selection differs from what's saved
- Applied at all five avatar display sites: message timeline, members
drawer, knock list, @mention autocomplete, notifications inbox
