…PI audit Removes props and slots that v15 types still declared but nothing read: MessageList's messages, hasMore, jumpToLatestMessage, loadingMoreNewer and messageLimit, VirtualizedMessageList's messages, CustomClasses.chatContainer, ComponentContext.LoadingErrorIndicator, the channel-list-inner SCSS rules and commented-out ChannelUnreadUiState leftovers. Restores behavior lost in the move to stream-chat v10: - MessageList shows its loading indicator while an older page loads - ChannelNavigation carries the str-chat theme scope and customClasses.channelList - channel-detail DM and pinned-message actions open via workspace navigation - the reply-count button honors Message.openThread - the gallery header renders a MessageTimestamp override - navigation without a provider warns once per operation Exports useIsCooldownActive and useMessagePaginator from the package root.
…he review fixes A nested `.str-chat` on ChannelNavigation reset the token overrides an app sets on the ChatView root and matched app CSS written for `.str-chat` roots (the tutorial's channel list grew to half the row). ChatView now provides an internal theme-scope context; ChannelNavigation applies `str-chat <theme>` only without one, and a bare ChannelList brings a `display: contents` scope. - MessageList raises the older-page indicator only when a tailward page can load - MessageTimestamp throws again without a `message` prop or a MessageProvider
Marks the removals in this branch as breaking for semantic-release. BREAKING CHANGE: `MessageList` no longer accepts `messages`, `hasMore`, `jumpToLatestMessage`, `loadingMoreNewer` or `messageLimit`, and `VirtualizedMessageList` no longer accepts `messages`; the lists render and paginate the message paginator. `CustomClasses.chatContainer` and the `ComponentContext.LoadingErrorIndicator` slot are removed. Inside `ChatView` the channel list no longer renders its own `str-chat <theme>` scope. See ai-docs/v15-breaking-changes.md (BC-019, BC-046, BC-047, BC-073, BC-074).

Use the selected item message for metadata fallbacks.
If item.message belongs to a different message than MessageContext.message, an item without createdAt or user receives the surrounding message's timestamp and sender. The timestamp override then receives item.message, so the header can show conflicting metadata. Derive both fallbacks from item.message ?? message, while preserving explicit item.createdAt and item.user values.

Guard the Windows emoji check during server rendering.
When Chat renders on a server with useImageFlagEmojisOnWindows enabled, ChannelNavigation can call useImageFlagEmojisOnWindowsClass. The shared hook then reads navigator.userAgent, which throws when navigator is unavailable.

Announce older-page loading to screen readers.
The default IconLoading renders with aria-hidden="true", so this branch does not announce the older-page load. Pass decorative={false}, role="status", and localized loading text to the default LoadingIndicator, or wrap it in an equivalent live region.

Goal
The v14 -> v15 breaking-changes audit (#3327) found public surface on master that v15 still declared but nothing read, plus a few v14 behaviors lost in the move to stream-chat v10. This PR removes the dead surface and restores the behaviors the maintainers wanted kept. One audit item was left out on purpose: porting the v14 fix #3305 (
b470bef37).Stacked PR: this targets
docs/v15-migration-guides-alignment(the guides PR), which is stacked on #3327. Merge those first; this PR's diff only makes sense on top of them.Implementation details
Dead surface removed:
MessageList:messages,hasMore,jumpToLatestMessage,loadingMoreNewer,messageLimit.VirtualizedMessageList:messages. Both lists render and paginate the message paginator; these props were typed but never read.CustomClasses.chatContainer, andchatContainerClassinuseChannelContainerClasses(nostr-chat__containerelement exists in v15).ComponentContext.LoadingErrorIndicatorslot. No SDK component rendered it; theLoadingErrorIndicatorcomponent is still exported..str-chat__channel-list-inner/__mainSCSS rules, the commented-outChannelUnreadUiStateleftovers, and a stalepaginator.next()JSDoc.ChannelListnow callstoTailinstead of the deprecatednext; they are the same function.Exports:
useIsCooldownActive(named in the migration guide) anduseMessagePaginator(named in AGENTS.md and #3237) are now reachable from the package root.Behaviors restored:
MessageListshows theLoadingIndicatorwhile an older page loads. Before, it showed only when theloadingMoreprop was passed.loadingMore={false}hides it. The indicator turns on only when a tailward page can actually load, so it no longer flashes during a jump or a newer-page load.ThemeScopeContextis provided byChatView. OutsideChatView,ChannelNavigation's root rendersstr-chat <theme>, and a bareChannelListwraps itself in adisplay: contentsscope element. InsideChatViewno nested.str-chatis added, because a nested one would reset token overrides set on theChatViewroot, and the bundled examples'.str-chatsizing rules would match the list.customClasses.channelListis applied again.useWorkspaceNavigation().openChannel, so a customWorkspaceNavigationProviderreceives them (before, they worked only insideChatView). With no navigation provider at all, each operation logs a one-time console warning;defaultWorkspaceNavigationitself stays silent.Message.openThreadagain, by falling back to the message'shandleOpenThread.ComponentContext.MessageTimestampoverride for items that carry their message.GalleryItem.messageis new, andModalGalleryand the channel-detail media view fill it.MessageTimestamprenders from itsmessageprop outside aMessageProvider, and still throws without the prop and the provider.Docs:

MessageListno longer acceptsmessages,hasMore,jumpToLatestMessage,loadingMoreNewerormessageLimit, andVirtualizedMessageListno longer acceptsmessages; the lists render and paginate the message paginator.CustomClasses.chatContainerand theComponentContext.LoadingErrorIndicatorslot are removed. InsideChatViewthe channel list no longer renders its ownstr-chat <theme>scope. See ai-docs/v15-breaking-changes.md (BC-019, BC-046, BC-047, BC-073, BC-074).Verification:

The ai-chatbot example build was not verified: it hung locally in a sandboxed environment. The theme-scope change was not checked visually in a browser.UI Changes
No intended visual change inside
ChatView. OutsideChatView, the channel list picks up the design tokens again, as in v14. TheMessageListloading indicator now appears while older messages load. No screenshots: the examples need Stream credentials to run.Summary by CodeRabbit
