Biome was failing CI on migrations/meta/0261_snapshot.json. Also settle assistant streaming/tool flags when SSE ends without a terminal frame, without clobbering Stop's finalized content. Co-authored-by: Cursor <cursoragent@cursor.com>
Auto-format the sim package for CI lint:check, and repair the Anthropic streaming tool-loop payload after an unsafe delete-to-undefined rewrite. Co-authored-by: Cursor <cursoragent@cursor.com>
…journal test Treat AbortError from reader.cancel as a cancelled pump result so soft-complete retains answerText. Point the workspace storage migration journal assertion at 0261_chat_include_thinking. Co-authored-by: Cursor <cursoragent@cursor.com>
Ignore terminal SSE error frames after the user aborts so "Client cancelled request" cannot overwrite "Response stopped by user". Co-authored-by: Cursor <cursoragent@cursor.com>
… scroll Add left-to-right shimmer on live thinking label/body, keep scroll working by shimmering an inner node, and follow the answer only while near the bottom. Co-authored-by: Cursor <cursoragent@cursor.com>
…ts only Abort the agent stream pump when the projected HTTP body is cancelled so provider work does not continue after disconnect. Limit AbortError soft-success to Agent blocks so Function/HTTP cancels still fail in logs. Co-authored-by: Cursor <cursoragent@cursor.com>
Paused chat runs with Include thinking enabled were dropping the flag when serializing the pause snapshot, so resume always rebuilt streams without thinking/tool SSE frames. Co-authored-by: Cursor <cursoragent@cursor.com>
Persist pump answerText onto the streaming execution before throwing on timeout, and carry that partial content into the failed block output so logs match what the client already saw. Co-authored-by: Cursor <cursoragent@cursor.com>
Match thinking UX: open while tools run, collapse when finished, and keep the panel open only if the user manually reopens it. Co-authored-by: Cursor <cursoragent@cursor.com>
Clear agentStreamActive and settle running tool chips when blocks error, timeouts cancel runs, or execution ends without stream:done so the output panel does not stay on live Thinking/Using tools chrome. Co-authored-by: Cursor <cursoragent@cursor.com>

Pause can interrupt a tool loop without tool end events; settling those chips as success incorrectly showed unfinished tools as complete. Co-authored-by: Cursor <cursoragent@cursor.com>
