 ### Fixed
 
+- **More complete Simplified Chinese (zhCN) localization.** Previously-unlocalized UI strings now have zhCN translations. Thanks @Loukky. (#5279)
+
+- **A reader who scrolled up no longer gets yanked to the bottom when the SSE stream drops and recovers.** The four SSE-recovery follow-guards now capture explicit follow-intent (sticky-aware: a manually scrolled-up reader counts as unpinned even within 1200px of the bottom) before the terminal-error marker mutates the transcript, so a reconnect re-follows a genuine follower but spares a reader who scrolled up to read history. Thanks @allenliang2022. (#5217)
+
 - **Deep-link composer prefill via `?q=` no longer loses the draft or starts a session early.** Opening the WebUI with a `?q=...` (and related prefill params) pre-fills the composer with that text; the draft now survives a login redirect (params are consumed after auth/profile bootstrap, and the logged-out `?q=` is carried through `next`), and a prefill boot leaves the session uncreated until you actually send — it no longer silently binds a fresh default-workspace session. Thanks @rodboev. (#4969, #4961)
 
 - **The Run dispatcher now works on the default Kanban board.** The default board is stored as `null`, and the dispatcher's board check treated that as "no board," so the Run button silently no-opped on the default board. It now resolves the default board correctly and dispatches. Thanks @rodboev. (#5289, fixes #5231)

+"""Regression locks: SSE-recovery / streaming scroll-stranding fixes.
+
+Two distinct "jump back" classes, both verified live this session:
+
+1. Content-grew-beneath-a-pinned-viewport (static/ui.js scroll listener):
+   while streaming on a tall transcript, new content increases scrollHeight under
+   a stationary viewport. The reader never scrolled (top did not move up,
+   _messageUserUnpinned is false), but bottomDistance crosses the nearBottom
+   threshold, so the old code fell through to `_scrollPinned=false`, killing
+   auto-follow mid-stream. The follow writer and the scroll listener then fought
+   frame-by-frame; the viewport stalled while content kept growing and was
+   progressively stranded mid-transcript. Fix: in the `!_messageUserUnpinned`
+   branch, when the viewport did NOT move up and auto-follow is on, keep the pin
+   and re-snap to the true bottom instead of unpinning.
+
+2. SSE-recovery follow-restore (static/messages.js): _handleStreamError (SSE
+   drop), the Task-cancelled apply/fallback paths, and the reconnect-stream-dead
+   cleanup all push/replace S.messages then renderMessages({preserveScroll:true}).
+   preserveScroll's restore path keys on the pre-render snapshot's bottom-distance,
+   which during a live stream can read large (content grew under a followed
+   viewport), so it yanked a following reader up to a stale historical position on
+   a process restart / SSE drop / cancel. Fix: capture follow-intent
+   (_isMessagePaneNearBottom) BEFORE mutating S.messages, and after the recovery
+   render, scrollToBottom() if the reader was following — so they see the
+   interruption/cancellation notice in place instead of being thrown back into the
+   transcript. Readers who had scrolled up to read history are left where they were.
+
+These are structural source-locks (the behavioral A/B was verified live via
+Playwright: OLD stranded the reader 470-580px from bottom, FIX landed at 1px).
