+# Web App: directory browsing de-raced, Project defaults reach new drafts, update dot explained, focused model catalog, "temporary workspace" unified
+
+## Directory browsing no longer mis-navigates under repeated clicks
+
+While a listing was loading, clicking a folder row again in the files panel compounded path segments (`home` → `home/home` → `home/home/home/home`) and stranded the user on "path not found"; the workspace picker could also be silently relocated when a slow directory response landed after a newer one. Listings are now bound to the directory they were fetched for (a double-click recomputes the same target regardless of timing), in-flight navigation disables rows and breadcrumbs, picker requests are sequenced so only the newest response wins (the editable path row included), and the `dir_not_found` server error renders localized copy instead of the raw English message with the malformed path in it.
+
+## Saving Project new-chat defaults resets the new-conversation draft
+
+Opening `/chat/new` once pinned the then-current Agent / workspace / approval mode into the per-user draft cache, and that stale draft shadowed any later change to the Project's new-chat defaults. Saving the defaults now strips the corresponding cached pins — typed-but-unsent text, staged skills and chips survive — and live-reseeds a draft page open in the same tab (its debounced persist would otherwise write the old values right back); other tabs pick the change up on their next visit. The model pin is still released exactly when the default model itself changes, keeping the "switch becomes default" carry-over intact.
+
+## The avatar update dot explains itself
+
+The sidebar avatar's update indicator now names the available release in a hover tooltip and accessible label (the update row's exact wording), and the collapsed icon rail's avatar shows the same indicator — previously the dot was unlabeled and the rail showed nothing. A passive subscriber gap in the version-info cache was fixed along the way so the rail sees results that land while it is mounted.
+
+## Model catalog opens focused on DeepSeek
+
+The models page now expands only the DeepSeek group by default; other vendor groups and user-defined groups start collapsed. While a search query is active, any group holding matches is force-opened (derived, not persisted) so results can never hide inside a collapsed group; expansion state still resets per visit.
+
+## "Temporary workspace" unified
+
+The auto-created session workspace is now consistently called 临时工作区 / "temporary workspace" across the workspace picker, its hints, the schedule form, server/SDK error messages, docs, and the penguin-sdk skill (v19) — replacing the mixed "auto temp directory" wording. Persisted keys, ids and the on-disk `workspaces/tmp-<8hex>` shape are untouched.
