Author	SHA1	Message	Date
Mohamed Boudra	e39f914a82	test(app): match the turn collapse reply by its last streamed chunk Back-to-back text chunks from the mock stream merge into one message depending on delivery timing, so the final reply and the folded message count vary run to run.	2026-10-24 08:28:49 +02:00
Mohamed Boudra	953b448774	test(app): seed e2e settings fields without assuming an empty settings blob The e2e page fixture now stores a chat display before specs run, so seeds that skipped whenever any settings blob existed never wrote their own field.

Mohamed Boudra Ready Waishnav Shreyan Dey Sebastian Parfitt	4b90b754c0	feat(app): fold finished agent turns behind a summary line Long agent turns bury the answer under intermediate messages, thoughts and tool calls. A new Chat display preference (Full / Collapse tool calls / Collapse turns) replaces the tool call detail level. Collapse turns folds everything a finished turn did before its final message into one summary line under the prompt; opening it shows those rows inline behind the same indent rail that expanded tool call groups now use. Expanded turns stay real timeline rows so virtualization, chat find and scroll-to-message keep working; find and outline jumps open the turn that holds their target. Opening or closing a turn stops following output so the summary stays under the pointer. Collapse turns is the default for new installs only. Existing settings were materialized on first launch, so stored blobs without the new field map from the legacy tool call detail level and otherwise stay on Full.

Stephen ZhouandClaude Opus 5.5	632a7f8859	fix(app): keep live workspace rows when a late creation snapshot arrives (#7758 ) A workspace.create.response carries the descriptor captured at provision time but is sent after the initial agent starts. A pin or title change made in between reaches the app first as a live update; the late response then replaced that row with the older snapshot, so a new pin vanished from the sidebar until the next directory update. Creation and progress snapshots now only seed rows the replica has not received; existing rows stay owned by directory updates. Archive rollback still restores a row that was removed.
