In `update_git_repositories`, a `.git` path outside the worktree root
can occur legitimately when `.git` is a gitfile (as in linked worktrees
and submodules) pointing to a directory in the parent repo. Previously
this triggered a `debug_panic!`, crashing debug builds.
Now we skip the path with a `debug_assert!` that it is indeed a file
(not a directory), so a genuine `.git` directory outside the worktree
root would still be caught in debug builds.
(No release notes because this is extremely hard to encounter until
https://github.com/zed-industries/zed/pull/53215 lands)

When toggling fast mode, the setting is now written to `settings.json`
under `agent.default_model.speed`, so new threads start with the same
speed. This follows the same pattern as `enable_thinking` and `effort`.
The `speed` field uses the existing `Speed` enum (`"fast"` /
`"standard"`) rather than a boolean, to leave room for future speed
tiers.
Example settings:
```json
{
"agent": {
"default_model": {
"provider": "zed.dev",
"model": "claude-sonnet-4",
"speed": "fast"
}
}
}

### Summary
Fixes duplicated Prompts/context in ACP threads after sending a message,
as reported in #53201.
### Root Cause
The thread already inserts the user prompt optimistically at send time.
If an ACP server also echoes UserMessageChunk updates for the same
prompt, the same content is appended again, which can duplicate rendered
context sections.
### Fix
Ignore echoed UserMessageChunk updates while a turn is actively running,
so user prompt content is not appended twice.
### Validation
- Reproduced with OpenCode ACP flow from the issue.
- Confirmed duplication appears after send (not in the input box).
- Confirmed duplicate Prompts/context no longer appears with the fix.

A couple of restore project group/workspaces functions weren't filtering
out project groups with empty paths, leading to an empty being shown in
the recent projects picker. This is the problem this PR solves:

Follow up to https://github.com/zed-industries/zed/pull/53283. That PR
replaced _where_ focus goes — from "always the center pane" to "the
saved element." But it didn't fix _when_ focus moves — it still moves
every time the sidebar closes, unconditionally. The problem is the saved
focus can be wrong... it's saved when the sidebar opens, but then it can
go to somewhere else after. An example:
1. Open sidebar → save focus (center pane), focus sidebar
2. Open agent panel from sidebar → focus moves to agent panel
3. Close sidebar → restore saved focus → **focuses center pane** (that's
what was saved in step 1, not the agent panel)
Effectively, this would still cause the agent panel to auto-dismiss.
This PR fixes it by no moving focus at all if the sidebar doesn't have
it. If the user already moved focus to the agent panel, there's nothing
to "restore".

tree-sitter query compilation (used to set up language grammars) is a
significant bottleneck in test setup. Profiling showed rust_lang()
creation taking ~270ms per test in dev builds, with nearly all time
spent in tree-sitter's query compiler.
With opt-level = 3, this drops to ~63ms locally — a 4x speedup on that
step. Across hundreds of tests that create language grammars (vim,
editor, collab, etc.), this ought to save substantial CI time.

I believe this PR makes the whole message editor more solid against
these cases because we're relying on `flex_basis` now to set the
max-width, which runs before we do any editor mode calculations. Tested
this a bunch and it seems to be pretty stable.

Commit eaf14d028a changed SvgRenderer::new() to eagerly deep-clone the
system font database and enrich it with bundled fonts at construction
time. Since every #[gpui::test] creates a TestAppContext →
App::new_app() → SvgRenderer::new(), and nextest runs each test in its
own process, this added ~2-3s of overhead to every GPUI-based test (~132
minutes total across the full suite).
Move the expensive work (deep-clone + load_bundled_fonts +
fix_generic_font_families) into a OnceLock inside the font resolver
closure, so it only executes on the first actual SVG render. Tests that
never render SVGs thus do not need to load the fonts which in itself can
be fairly expensive.
This also bumps the opt-level for crane lift and some other wasmtime
crates, as only wasmtime isn't really sufficient

Release Notes:
- persist draft messages in ai thread when a new thread is created so we

Question:
need some guidance on how to persist a thread when the `draft_prompt` is
present but the message is unsent because currently having a draft
prompt in the agent input box and thenmaking a new agent thread copies
the prompt over to the new thread(changes from this pr) but on going
back to the old thread new thread is destroyed
This PR adjusts how project group removal works in the sidebar to be
project group aware. Removal is now a batched operation, and supports a
contextually appropriate fallback active workspace fallback. In the
process of removing this, I had to chase down and fix other broken code:
- Removes the "move to new window" actions
- Changed the sidebar to store things in "most recently added" order
- The recent project UI was still using workspaces, instead of project
groups
- Adjusted the archive command to use the new APIs to remove the
workspace associated with that worktree (cc: @rtfeldman)
- The property tests where still using indexes and workspaces instead of
project groups

After a user creates successfully creates a new git worktree we reset

This PR adds spreadsheet-style independently resizable columns (dragging
changes total table width) and fixes scrolling issues in variable list
mode.
**What changed:**
- Adds `ResizableColumnsState` struct for independently resizable
columns (spreadsheet-style)
- Adds `ColumnWidthConfig::Resizable` variant for spreadsheet mode
- Adds `DraggedResizableColumn` drag payload type
- Adds `ResizableHeaderInfo` for double-click-to-reset functionality
- Adds `render_resize_handles_resizable` function for resize handles
rendering
- Adds horizontal scroll handle to `TableInteractionState`
- Adds `.on_drag_move::<DraggedResizableColumn>` handler to Table for
drag resizing
**Bug fixes:**
- Fixed missing vertical scrollbar in variable list mode
- Fixed half-broken scrolling in variable list mode (added
.measure_all() to make scrollbar aware of the height of the table)
- Moved vertical scrollbar to be pinned at the right side of the pane
with table — previously it was attached to the table content and was
pushed off-screen when table content was too wide
**API addition:**
```rust
// New variant added:
pub enum ColumnWidthConfig {
Static { widths: StaticColumnWidths, table_width: Option<DefiniteLength> },
Redistributable { entity: Entity<RedistributableColumnsState>, table_width: Option<DefiniteLength> },
Resizable(Entity<ResizableColumnsState>), // NEW: spreadsheet-style
}
```
**Callers updated:**
- csv_preview: Changed from `ColumnWidthConfig::redistributable()` to
use new resizable mode
- git_graph: Added `resizable_info` parameter
**Context:**
This is part 3 of a 3-PR series improving data table column width
handling:
1. [#51059](https://github.com/zed-industries/zed/pull/51059) - Extract
modules into separate files (mechanical change)
2. [#51120](https://github.com/zed-industries/zed/pull/51120) -
Introduce width config enum for redistributable column widths (API
rework)
3. **This PR**: Add independently resizable columns + fix variable list
scrolling (new feature + bug fixes)
The series builds on previously merged infrastructure:
- [#46341](https://github.com/zed-industries/zed/pull/46341) - Data
table dynamic column support
- [#46190](https://github.com/zed-industries/zed/pull/46190) - Variable
row height mode for data tables
Primary beneficiary: CSV preview feature
([#48207](https://github.com/zed-industries/zed/pull/48207))
This work is based on the [original draft PR
#44344](https://github.com/zed-industries/zed/pull/44344), decomposed
into reviewable pieces.

The "Hover Popover → Delay" setting item had its json_path set to
"hover_popover_enabled" (copy-paste error from the item above it),
introduced in #40739. This caused:
- "Copy Link" generating a wrong zed://settings/hover_popover_enabled
URL
- #hover_popover_delay filter returning no results in settings search
- Telemetry reporting delay changes as hover_popover_enabled
The pick/write closures were always correct, so the setting itself
functioned normally.
after the fix, filter works correctly

When a subagent was spawned while the parent had runtime-modified
settings (fast mode, thinking, etc.), the subagent would start with
defaults from `AgentSettings` instead of inheriting the parent's current
values.
This adds `inherit_parent_settings` as a single place in
`Thread::new_subagent` that copies all runtime-mutable settings from the
parent:
- `speed`
- `thinking_enabled`
- `thinking_effort`
- `summarization_model`
- `profile_id`
These are the same properties that `set_*` methods already propagate to
`running_subagents` — this fix ensures they're also inherited at
creation time.

Closes #ISSUE
Release Notes:
- Fixed a bug where a cleverly crafted directory name could lead to
remote code execution
This PR adjust the name of the worktree within the agent panel: we
display `main` if you're in the main worktree and then the worktree name
when in a linked one. Additionally, I also took the opportunity to fix
something that confused me in the general worktree picker: for the list
item that represented the main worktree, we were using the current
checked out branch name for that item's name. I think that's a bit
incorrect, given the _name_ of that worktree isn't the name of the
branch you have active at that moment. For now, I'm using simply `main`
as the worktree name. Lastly, also added a little blue check icon in the
worktree _and branch_ picker to highlight which worktree/branch is
currently active.

### Summary
Keep the prompt editor’s max-width centering, but move the footer
controls out of the same flexible wrapper as the full-height editor and
add `min_h_0()` shrink guards so the editor no longer overlaps the
footer in zoomed/full-screen mode.

When filtering themes with a query that matches nothing (e.g., "zzz"),
`show_selected_theme` returned `None` and overwrote `selected_theme`.
Clearing the filter then lost track of the previous selection and
defaulted to index 0.
The fix only updates `selected_theme` when `show_selected_theme` returns
`Some`. Same change in both the theme selector and the icon theme
selector.
## Context
When `update_matches` runs a filter that yields zero results,
`show_selected_theme` returns `None`. The old code unconditionally
assigned that back to `selected_theme`, wiping out the previous
selection. When the user clears the filter, the selector falls into the
`query.is_empty() && selected_theme.is_none()` branch and resets to
index 0 instead of restoring the original pick.

## How to review
The fix is the same one-line change in two files:
1. `crates/theme_selector/src/theme_selector.rs` — line 458
2. `crates/theme_selector/src/icon_theme_selector.rs` — line 272
The rest is test infrastructure:
3. `crates/theme/src/registry.rs` — `register_test_themes` /
`register_test_icon_themes` helpers
4. Tests in both selector files covering the empty filter → clear filter
flow

## Release notes
- Fixed theme selector losing the selected theme after filtering with a
query that matches nothing and then clearing the filter.
Before, every creation of `AnchorSeekTarget` called
`MultiBufferSnapshot::buffer_for_path`, which seeks the excerpts sum
tree. Now we avoid that by
- looking up the buffer snapshot for the anchor's buffer in the
`buffers` map (keyed by `BufferId`)
- handling the case where the anchor's buffer doesn't exist at the
original path key with a separate `AnchorSeekTarget::Missing` variant
We also added a separate optimization to `AnchorSeekTarget::cmp`, to
skip the full `PathKey` comparison when the cursor's `PathKeyIndex` is
the same as the anchor's. This should help with singleton multibuffers.

Closes#39532
## Summary
Move the long-running agent "generating" spinner into a dedicated
`GeneratingSpinner` view.
Previously, the generating state rendered `SpinnerLabel` inline as part
of the full thread view. This change keeps the same spinner styling, but
isolates it into its own small view so the animation no longer needs to
live directly inside the larger thread UI subtree while the agent is
running.
