Assistant responses are now stored as structured output items on message.output, with message.content left empty. The action payload built in chatActionHandler still sent message.content only, so action functions received assistant messages with an empty content property. Derive the content from the structured output via getOutputText, falling back to message.content, matching how the rest of Chat.svelte resolves assistant text.
Fixes#26672
When a chat is started from the home page, the URL is switched to /c/{id} with
history.replaceState, so the Chat component is never remounted and chatIdProp
stays empty for the lifetime of that view. Both websocket recovery paths,
handleSocketConnect and the chat:active fallback, are gated on chatIdProp and
therefore never run for these chats. After any websocket drop during a response
(mobile backgrounding, VPN or IP change, wake from sleep) the completed response
is never fetched and the chat stays stuck in a loading state until a manual page
refresh. Chats opened directly via /c/{id} recover fine, which is why the bug
only reproduces reliably on freshly started chats.
Gate both recovery paths on the chatId store instead, which is set for every
persisted chat, and let loadChat fall back to it so the recovery reload also
works when chatIdProp is empty. Chats opened via /c/{id} behave exactly as
before and temporary chats stay excluded.
The same gate likely explains the remaining reports in #26315.
Fixes#26844
A chat created in place (new chat -> first message) keeps chatIdProp
undefined because the URL is swapped via history.replaceState without a
remount, so none of the chatIdProp-gated updateLastReadAt paths fire and
the chat is never persisted with a last_read_at. Starting another new
chat via initNewChat reset $chatId without marking the outgoing chat
read, so on refresh updated_at > last_read_at (NULL) and the chat shows
as unread in the sidebar.
Mark the outgoing chat read in initNewChat, mirroring navigateHandler.
