On Linux with client-side decorations, opening the workspace sidebar
squared off the window corners on the sidebar's side while the rest of
the window stayed rounded:

/>
Previously, `client_side_decorations` took a `border_radius_tiling`
override that `MultiWorkspace` used to deliberately square the window
shape on the sidebar's side, since the sidebar painted a square
background that would otherwise poke out past the rounded window border.
The title bar and status bar already skip rounding their corners on the
sidebar side, implying the sidebar is expected to own those window
corners — it just never rounded them.
This PR makes the sidebar round its outer corners the same way the title
bar and status bar do (including overlapping the 1px window border on
untiled edges to avoid a transparent gap in the rounded corners), and
removes the now-unneeded `border_radius_tiling` parameter so the window
border and backdrop round purely based on actual tiling state.
Only applies when the window uses client-side decorations, so macOS and
Windows are unaffected.
Fixes#54724
Release Notes:
- Fixed square window corners on the sidebar side of client-decorated
(Linux) windows when the workspace sidebar is open.

Recently, we introduced the ability to pick, from the plus icon button
in a project's header in the sidebar, which of the currently loaded
worktree you'd like to create a new thread on. This PR extends this
ability by allowing you to _create_ a new worktree from there as well.
Turned out this just felt like a natural move after playing around with
the change internally; we had a good amount of internal asks for this.
What's exposed in the menu is exactly the same options available in the
worktree picker, following the same display rules.

/>
Release Notes:
- Agent: Enabled creating a new worktree from the sidebar's "new thread"
icon button.
This fixes archive cleanup for agent threads so Zed only removes
worktrees it explicitly created, rather than treating every linked
worktree under the configured managed directory as safe to delete. When
Zed creates a worktree, it now records it in the local database along
with the creation time of the worktree's git metadata directory
(`.git/worktrees/<name>/`). Archive planning requires that record, and
right before deleting anything, Zed re-stats the directory and compares
creation times: if the worktree was removed and recreated outside Zed
(or the time can't be read at all), deletion is skipped and the stale
record is dropped. Every failure mode fails safe by leaving the
directory untouched.
For remote (SSH) projects, the stat runs on the remote host via a new
`GitWorktreeCreatedAt` request. Worktrees created by a different Zed
install (another release channel, or another machine connecting to the
same host) have no record in the local database and are therefore never
auto-archived, which is the intended conservative behavior.
Closes https://github.com/zed-industries/zed/issues/57155
Closes AI-352
Release Notes:
- Fixed archiving an agent thread incorrectly deleting manually-created
git worktrees.
Closes AI-404
This PR fixes a flicker that was happening when clicking on an empty
draft thread item in the sidebar, given we were going through the whole
regular activation flow despite the thread already being active. So, the
fix here was just extracting a boolean so we can identify whether the
thread is active in the workspace and if so, not doing nothing in the
on_click handler of the thread item.
Release Notes:
- Sidebar: Fixed a flicker when clicking on an empty draft thread.
Sometimes, landing in the archive view at first, particularly after
importing ACP threads, can be confusing as there's not an immediately
available "create new thread" button users can click on.
Release Notes:
- N/A
On transparent or blurred window backgrounds, several agent panel
surfaces and
the multibuffer header rendered drop shadows and fade gradients that
have no
opaque surface to blend into, so they showed up as dark halos or colored
patches:
- agent message boxes and the activity bar (drop shadows)
- diff-hunk Reject/Keep controls (drop shadow)
- the diff review pane (double-painted `editor_background`)
- agent thread-list rows, the conversation title edit affordance, and
sidebar
project headers (fade gradient)
- the multibuffer buffer header (`editor_subheader_background` + sticky
shadow)
These are skipped when `window_background_appearance` isn't `Opaque`.
Opaque
windows are unchanged; on transparent windows the elements stay
delineated by
their borders and truncate text with an ellipsis instead of fading.

This PR hides the chevron and removes hover styles from the project
header when there is an active search, given groups can't be collapsed
while that's happening. We could allow it, but I think it's not super
worth it; this feels like like a pragmatic move.
Release Notes:
- Sidebar: Fixed a bug where affordances to collapse the project header
would appear when searching.
- Improve icon colors and gradient overlay
- Fix a bug where the plus icon button as visible in the sticky header
despite the menu being closed
- Made menu positining consistent between the plus/ellipsis menu
- Other small spacing/wording tweaks

Terminal thread title prefixes now strip surrounding brackets before
condensing leading dots, so bracketed ellipsis prefixes render with the
same ellipsis icon as unbracketed prefixes.
Release Notes:
- Improved terminal thread icons for bracketed ellipsis title prefixes
Similar treatment to the ellipsis menu, where we keep the icon button
that triggers the menu visible, so we know where the menu is anchored
to. This was missing from a recent PR where we improved the drafts UX.

This PR adds a right-click menu to thread items in the sidebar. A big
motivation for this addition was surfacing the "regenerate thread title"
action. And because this action and the "open thread as markdown" action
previously only worked on the already-loaded agent panel, there was a
load of plumbing needed to make that work even for threads in workspaces
that haven't been loaded, mostly using the thread metadata store. At the
end of the day, the title regeneration feature is only possible for the
Zed agent, so this is gated from external agents. But I believe it's now
in a slightly nicer spot due to some refactors to better expose the
state in which the title regeneration can fall into.
Release Notes:
- Agent: Added a right-click menu to thread items in the sidebar,
allowing to regenerate a thread title, rename a thread title, open the
thread as markdown, and archive it.

channels_with_threads opened a fresh SQLite connection per

Run the per-channel checks on a background thread and cache the

Closes AI-351
This PR builds on top of
https://github.com/zed-industries/zed/pull/57692 by improving the draft
threads UX in the context of worktrees. If you have more than one
worktree loaded for a given group, clicking on the plus button will now
display a menu allowing you to choose for which worktree you'd like to
open a new thread in. This felt particularly relevant in the case of
discarding a draft within a worktree when that was the only thread item
for that worktree, making it hard to come back to it.
Added some extra stuff in here as well with regards to better draft
management. Most notably, if you created a new thread and then typed
something, this draft thread would show a timestamp that's relative to
the creation time of the thread. However, if you moments later deleted
the draft content and then typed something up again, the timestamp would
be stuck in the creation time. That felt wrong because by erasing the
content you effectively reset the draft. So, this branch makes it so, in
this context, the timestamp would be reset to now.
Release Notes:
- Agents: Added improvements for the draft thread UX particularly in the
context of worktrees, allowing to choose for which worktree to open a
thread in when the group contains more than one.

This PR makes sure an empty draft thread is reflected in the sidebar by
an empty thread item. The main goal of this change is to make the
existence of the drafts feature more intuitive and clear. We don't only
display the draft item now when moving away from it, but rather whenever
you're focused on it.
Release Notes:
- Agent: Improved the UX of the draft feature by always displaying a
corresponding thread item in the sidebar, even if the thread was still
empty.

The threads sidebar rebuilds its `Vec<ListEntry>` from scratch on events
that touch thread/sidebar state (status changes, title generation, new
live info, sending a message, etc.). It previously called
`ListState::reset` after every rebuild, which rewrote every list item to
`Unmeasured`. On the next render frame, the sticky project header had no
measured bounds for the next project header.
The sticky project header uses `ListState::bounds_for_item` for the next
project header to compute how far it should be pushed off screen. When
those measurements were missing, it temporarily fell back to `top_offset
= 0`, snapped fully into view for one frame, then popped back once the
list was remeasured.
Fix: preserve list measurements for entries whose identity and layout
shape did not change. `EntryShape` captures each entry's identity plus
height-affecting project-header flags. `update_entries` snapshots the
old shapes, rebuilds contents, then splices only the changed shape range
into `ListState`. Unchanged items keep their measured bounds, so the
sticky header remains in its pushed-off position across same-shape
updates.
This also adds a regression test that renders a two-project sidebar,
scrolls into the sticky-header push-off state, performs a same-shape
thread metadata update, and verifies the next header's measured bounds
are preserved.
Closes AI-196
Release Notes:

down through the ellipsis menu.
Closes AI-285
Similar to how we display whether there are running threads or a thread
waiting for permission in the collapsed version of the project's header
in the sidebar, I was missing the "unread" state from being shown. I had
to change the approach here as to how we extract this information
because the previous method was relying on observing the state of the
list entries within the sidebar at every `rebuild_contents` run, and
given there aren't any list entires when the project is collapsed, it
wouldn't work.
Release Notes:
- Agent: Added the notification indicator on collapsed project headers
in the sidebar when a thread completes.

If we have empty drafts, they don't show up in the UI, so you can't get
rid of them. But they currently blocked worktree archival. Which is
particularly troublesome with terminal agents in a few cases.
This should hopefully solve the issue for terminals, but I think I need
to do a follow-up to investigate what happens when the last draft is
closed.

Right now the recent project picker has different confirm behavior
depending on if a user had open their sidebar in their current Zed
session. If the sidebar had been open the recent project picker adds the
selected project to the multi workspace and makes it the active
workspace, without removing anything. If the sidebar hadn't been open
the recent project picker would replace the active workspace within the
multi workspace.
This caused confusion because the same UX flow had two different
outcomes depending on Zed's state that wasn't obvious to users. This PR
mitigates this by always adding the project to the window while AI
features are enabled. Future follow ups will include the ability to
disable the sidebar, but that's blocked on the agent panel not having a
way to view active threads currently.
This also caused issues in the parallel agents workflow because
replacing a workspace would drop the workspace, thus causing any
terminal processes or threads to be dropped as well.
