3c0092eb revert(ai): drop chat() messages type widening from this PR Pulls the @tanstack/ai changes back out — the chat() messages-option widening to accept UIMessage[] is a separate concern from the stream() server-function feature this PR is about. Restores the example's `as any` cast with a comment, drops the @tanstack/ai minor bump from the changeset, and reverts chat/index.ts to its pre-PR state. Also bumps the example adapter to gpt-5.2.

b821f2ed feat(ai-client,ai): narrow stream() callback to UIMessage[] and accept UIMessage[] in chat() Drops the `as any` / `as Array<UIMessage>` casts previously needed when wiring useChat through a TanStack Start server function into chat(). The stream() factory now declares Array<UIMessage> (with a runtime assert matching the ChatClient invariant), and chat()'s messages option accepts UIMessage[] directly alongside ConstrainedModelMessage[] — the runtime already normalised both via convertMessagesToModelMessages.

87dba45b fix(ai-client): filter SSE non-payload fields and drop unterminated trailing buffer Refine the SSE parser so the throw-on-parse-failure behavior doesn't regress on legitimate SSE traffic: - parseSSEChunks now skips SSE comment lines (`:`) and non-data fields (`event:`, `id:`, `retry:`) which proxies and CDNs commonly inject as keepalives. Previously these would have flowed into JSON.parse and thrown, killing otherwise-healthy streams behind any infrastructure that injects SSE control lines. - readStreamLines no longer yields the unterminated trailing buffer at stream end. A non-empty buffer means the connection was cut mid-line, so the content is partial by definition — yielding it would feed truncated JSON to the parser and surface a misleading RUN_ERROR for what is really a transport-layer issue. Warn and discard instead. Bare-line JSON (legacy/raw mode) is still accepted to preserve the existing public behavior covered by the `should handle SSE format without data: prefix` test.

ad3d414f fix(ai-client): use EventType enum in server-function stream tests Type-check was failing on CI because the new server-function and RPC async-iterable test fixtures yielded raw string literals for chunk type, which don't satisfy the EventType enum required by StreamChunk. Switch to the enum and add the required threadId to RUN_FINISHED. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

eb4bbfc5 docs(ai-client): reframe stream() server-function description Lead with what stream() does (typed RPC into useChat), instead of calling a server function "just a fancy/async API endpoint."
