Summary

Brings the Helix fork of Zed up to date with zed-industries/zed HEAD (992f395c3d), absorbing 256 upstream commits over 10 days. Clean merge — only 6 trivial conflicts (5 workflow/deletion + 1 import-block), zero Helix-side signature-drift repairs needed, build green on first attempt, full E2E green for both zed-agent and claude personalities.

This is the first upstream merge since 002029 that required zero "Pre-existing Breakage Repaired" entries.

Changes

  • Merge remote-tracking branch 'upstream/main' (b2993c0b01) — 256 upstream commits including the compaction cluster (built-in /compact slash command, auto_compact setting), d7ac5e6cf4 "Preserve waiting tool call status on updates" (+602 lines), 215ca2fb0b "Typed workspace errors", 116e4bc184 "Inherit source agent without draft content", 27191913e9 "Cumulative token usage", 56b71271c4 "Enable ACP session usage and deletion features", 620ceaaaca "Flush thread content to database on app quit", and a98485809b "Return typed completion errors from Cloud provider" (which deleted crates/language_model/src/model/ entirely).
  • docs(porting): add Merge 002077 entry (256 upstream commits, 0 breakage) (38d4f86809) — new ## Merge 002077 (2026-06-12) section in portingguide.md documenting all 6 conflicts, the auto-merge survival check, and the risks that turned out to be non-issues.

Conflicts resolved

  1. .github/workflows/run_cron_unit_evals.yml, run_unit_evals.ymlgit rm (upstream deletion; Helix doesn't use Zed's CI).
  2. .github/workflows/slack_notify_first_responders.yml--theirs.
  3. crates/language_model/src/model/mod.rs — accept upstream deletion (entire model/ directory removed; CloudModel relocated to language_model_core + language_models/src/provider/cloud.rs). No Helix surface referenced it.
  4. crates/recent_projects/src/dev_container_suggest.rs — kept Helix's use settings::Settings; (Helix suggest_dev_container guard) + upstream's new use std::path::Path; (new parameter type).
  5. crates/title_bar/src/title_bar.rs — import block: kept Helix's cloud_api_types::Plan + cfg-gated external_websocket_sync::{...} AND added upstream's new command_palette_hooks::CommandPaletteFilter.

Helix surface — auto-merge survival check

All Helix critical fixes and load-bearing patches survived the merge cleanly with no manual conflict in any Helix-touched source file (agent.rs, acp_thread.rs, agent_panel.rs, conversation_view.rs, workspace.rs, agent_servers/src/acp.rs, zed/src/main.rs, extensions_ui.rs, feature_flags/src/flags.rs):

Planning-time risks that turned out to be non-issues

  • d7ac5e6cf4 "Preserve waiting tool call status" — auto-merged; PR Restore lost streaming reveal-emit + add e2e Phase 15 cadence test #55 emit site survived.
  • Compaction cluster (~1700 net lines) — auto-merged; no WS payload schema changes (grep "compact\|cumulative_token_usage" crates/external_websocket_sync/ returns nothing).
  • 215ca2fb0b typed workspace errors — auto-merged; Helix surface has zero Workspace::show_error call sites, so the typed-error migration is not needed.
  • 116e4bc184 source-agent inheritance — auto-merged; Fix 1b's first-statement position survives.
  • 620ceaaaca flush-on-quit — auto-merged; no interaction with WS-authoritative store.
  • 56b71271c4 ACP session usage/deletion stabilisation — auto-merged; no Helix AcpConnection override needed.

Validation

  • ./stack build-zed dev: green (8m 14s, 0 errors, 3 unused-import warnings — all in upstream code).
  • Silent-drift sweep (ActiveView / set_active_view / draft_threads / background_threads / selected_agent_type / smol::Timer / non-tuple Stopped / Workspace::show_error in Helix surface / cumulative_token_usage-in-WS / compact-in-WS): all zero hits or only expected matches.
  • E2E zed-agent only: PASSED (full phase suite; store validation 14 interactions / 0 interrupted/cancelled / 4 sessions / response entries isolation PASSED / thread title sync PASSED).
  • E2E zed-agent,claude: PASSED (both personalities green; store validation PASSED).

Test plan

  • ./stack build-zed dev (green)
  • E2E zed-agent (green)
  • E2E zed-agent,claude (green — both personalities)
  • Silent-drift sweep (all clean)
  • Helix sandbox-versions.txt ZED_COMMIT bumped to the new merge HEAD (38d4f86809) in companion helixml/helix PR

The regression introduced in zed-industries#53453 where selecting a remote branch from
the branch picker checked out the remote tracking ref directly, leaving
the repository in detached HEAD state. Instead of creating a local
branch that set the remote branch as it's upstream.

The fix was reverting the old checks we did before zed-industries#53452 was merged to
figure out if the branch was valid, remote only, local, or local without
the upstream set. Depending on the type of reference it is Zed will
check it out, or create/set the branch with remote tracking to its
upstream branch.

I also added a regression test to prevent this from happening again in
the future

## Context

When the "Switch branch" picker is opened from the git commit modal and
the user presses Enter, a `\n` character was inserted into the input
instead of confirming the branch selection.

The `"GitCommit > Editor"` keymap context bound `enter` to
`editor::Newline`. This context matches *any* `Editor` descended from
`GitCommit` in the element tree, including the single-line search editor
inside the branch picker popover. Because a context-path binding is more
specific than the global `enter: menu::Confirm` binding, it took
precedence and the picker never received the confirm action.

The commit message editor uses `EditorMode::AutoHeight` (reported in key
context as `mode == auto_height`); the picker's search editor uses
`EditorMode::SingleLine`. Narrowing the context to `"GitCommit > Editor
&& mode == auto_height"` restricts the `editor::Newline` binding to the
commit message editor only. Single-line editors inside the same modal
now fall through to the global `enter: menu::Confirm`, which correctly
confirms the selection.

Closes zed-industries#58022

## How to Review

Three identical one-line changes, one per platform keymap
(`default-linux.json`, `default-macos.json`, `default-windows.json`):

- `"GitCommit > Editor"` → `"GitCommit > Editor && mode == auto_height"`

Closes [zed-industries#58343](<zed-industries#58343>)

This crash happened because Helix paste restored selection using the raw
clipboard text length, but buffer edits normalize CRLF line endings to
LF before inserting. When pasting CRLF text at or near EOF, the restored
selection could extend past the normalized snapshot length and panic in
`MutableSelectionsCollection::select_ranges`. The fix normalizes the
text before measuring it for selection restoration and adds regression
coverage for CRLF paste in Helix mode.

## Summary

This PR fixes horizontal jumping of the IME candidate window during text
composition.

On the shared `selected_bounds` path used by Windows, the candidate
window no longer follows the preedit caret character-by-character.
Instead, it anchors to the start of the current visual line, which keeps
the candidate window stable while typing.

Linux Wayland uses a different IME positioning path, so it was not
affected by the original implementation in this PR. This PR now also
includes a Wayland-specific adjustment so that Wayland uses the same
visual-line anchoring behavior.

## Changes

1. **Shared / Windows path**
Updated `selected_bounds` in `crates/gpui/src/platform.rs` to use a
visual-line-aware anchor for preedit text.

This removes the distracting horizontal movement of the candidate window
while typing and keeps the anchor aligned with the active visual line.

2. **Linux Wayland path**
Updated the Wayland IME area calculation in
`crates/gpui_linux/src/linux/wayland/window.rs` to use the same
visual-line-start anchoring strategy for preedit text.

This brings Linux Wayland in line with the Windows behavior while
preserving Wayland's platform-specific IME handling.

## Notes

I had previously tried a separate Wayland-specific fix in
5d0c968, but later reverted it in
8cfe7a2 because the behavior was not
good enough and it regressed the original positioning behavior.

The current Wayland implementation is a new, simpler approach that keeps
the original behavior intact while also removing horizontal
candidate-window jumping.

…ries#58346)

This centralizes some repeated logic across `cloud_api_client`, to map
generic request failures (`ConnectionFailed`, 401s) to errors and read
response bodies, handling failures there too.

Closes CLO-759.

Release Notes:

This change adds metrics for evaluating editable context collectors and
the collectors themselves:

- `cursor excerpt`: small area around the cursor.
- `current-file`: the full file that contains the cursor.
- `edit-history`: excerpts around edit history edits.
- `edit-history-file`: full files referenced by the edit history.
- `git-log`: files related to the cursor file according to recent git
co-change history.
- `oracle-file`: full files referenced by the expected patches. This is
an oracle/evaluation-only source because it uses the target patch.

Individual collectors can be enabled by passing a comma-separated list
like this: `ep context --type=edit-history,current-file`. There's also a
preset, `--type=editable`, which will enable all collectors except
oracle.

This change also adds the
`.prompt_input.related_files[0].excerpts[0].context_source` field.

Editable context is only accessible via ep-cli for now.

Following up on zed-industries#57644 by @cameron1024, this PR updates `merman` to
v0.6.

With merman 0.6's new raster-safe SVG pipeline, Zed can move generic
`usvg`/`resvg` cleanup passes out of this crate and rely on merman for
them instead.

**What's moved to merman:**
- `foreignObject` fallback text generation
- Unsupported CSS cleanup
- Invalid SVG attribute cleanup

**What's kept in Zed:**
- Theme CSS injection and accent color assignment
- Zed-specific fallback overlay handling

**Integration note:**
In merman v0.6, fallback overlay groups are marked with
`data-merman-foreignobject="fallback"` and preserve source classes like
`node` or `section-*`, so host CSS can still style fallback text. This
PR updates Zed's accent tracker to check for this marker, ensuring
fallback overlays are not treated as real layout nodes.

I also added a render-stage test for the new contract: the SVG output
from `render_mermaid` is already raster-safe before Zed-specific
post-processing runs.

Closes AI-286

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.

The parser stores emitted byte offsets between partial tool-call parses.
Because partial JSON can be repaired differently as more bytes arrive, a
byte offset that was valid in an earlier string can land inside a
multibyte character in a later string. We now normalize those offsets
with `find_char_boundary` before slicing.

Added property tests covering boundary-sensitive write/edit streaming
sequences to prevent regressions.

Very often, I'd wake up, to which point there's a new Nightly release
out, and the update button would be stuck in the "Downloading..." step.
It'd only immediately change its state to "Restart" once I quit the app

callback to trigger a re-render.

## Summary

Exposes the existing recursive pane-size reset as a command-palette
action, so it can be invoked outside of vim mode.

The center pane grid's sizes can already be evened out by
double-clicking a divider, or via `vim::ResetPaneSizes` (`ctrl-w =`)
when vim mode is on, but there is no general action for it — so users
not in vim mode have no discoverable way to undo a drifted split layout
in one step.

## How it works

`workspace::ResetPaneSizes` (palette: "workspace: reset pane sizes")
calls the existing `Workspace::reset_pane_sizes`, which resets every
`PaneAxis` in the center pane group to equal flexes, recursing into
nested splits. The split structure is preserved — no panes are added,
removed, or rearranged, only their sizes are equalized. This is the same
path the vim `ctrl-w =` binding and the divider double-click already
use.

## Out of scope

- Docks (left/right/bottom panels) — they keep their existing `Reset
Active Dock Size` / `Reset Open Docks Size` actions.
- The terminal panel's internal splits — it is a separate panel, not
part of the center pane group.
- No default keybinding (palette-only); vim users keep `ctrl-w =`.

## Testing

Added `test_reset_pane_sizes`: builds a nested split (a horizontal axis
of three panes whose last child is a vertical split), skews every axis's
flexes, dispatches the action, and asserts every axis returns to uniform
sizes.

Release Notes:

- Added a `workspace: reset pane sizes` command that equalizes the sizes
of all panes in the center group
## Summary
- add an editor action for selecting the contents of the innermost
enclosing bracket pair

This PR fixes some cases where scrolling is choppy due to a user
inputting a scroll event while a list state is going through a
remeasure. Currently, the list state would ignore the user's scroll and
fall back to the pending scroll position, this PR fixes this by rebasing
the pending scroll onto the user's new scroll position.

…ies#58981)

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.

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
We recently changed this given some new models (e.g., Fable) don't allow
turning thinking off. In those cases, we are not rendering the split
button anymore, but we should still display the thinking icon, so they
look a bit more consistent.

Release Notes:

- N/A
Audited the AI documentation against the implementation

## Changes

- **tool-permissions**: `skill` tool patterns match the absolute
`SKILL.md` path, not the skill name (fixed the table, example pattern,
and added a clarifying note).
- **external-agents**: Gemini CLI receives Zed's Google AI key when no
env key is set; extension-provided agents are deprecated in favor of the
ACP registry.
- **inline-assistant**: alternatives run alongside the inline assistant
model (not just the default model); fixed a broken anchor and
`gpt-4-mini` → `gpt-5-mini` model id typos.
- **mcp**: corrected the extensions menu item name ("Install New
Servers…"), the remote server `url` example, and removed the nonexistent
`thinking` tool from the profile example.
- **agent-panel**: "New From Summary" lives in the New Thread menu;
corrected the `@`-mention type list (no "instruction files"; added Fetch
and Branch Diff).
- **use-api-access**: DeepSeek default `api_url` includes `/v1`.
- **skills**: folder name is a convention not a requirement; long
descriptions warn rather than fail (measured in bytes); hidden skills
are also `@`-mentionable; dropped the unenforced consecutive-hyphen
rule; reconciled the no-remote-registry note with GitHub import.
- **edit-prediction**: `alt-tab` and `alt-l` are bound across platforms;
predictions are throttled rather than fired on every keystroke.
- **getting-started, windows-and-projects, parallel-agents**: Panel
Layout lives in the title-bar user menu, with
`workspace::UseAgenticLayout`/`UseClassicLayout` action references.

Release Notes:

- N/A

When the agent panel's thread is empty, the toolbar no longer shows the
labeled agent dropdown on the far left. Instead, it uses the same layout
as an active thread: a stable plus icon button on the far right, and the
left slot displays a muted "New {agent} Thread" placeholder title —
matching the sidebar's draft thread item. As soon as you type into the
message editor, the title shows your prompt text instead, reusing the
sidebar's draft label truncation logic.

Release Notes:

- Improved the agent panel's empty-state toolbar to show a "New {agent}
Thread" placeholder title (or your draft prompt as you type), with a
stable new-thread button on the right.

This PR fixes an issue where font properties like bolds and italics
would be lost when falling back to a fallback font.

The problem we identified was that when loading the fallback fonts, we
were just loading them by name. This meant that when the original font
had a different font weight (e.g., bold) or style applied to it this
would not cascade to the fallback font.

To reproduce the problem, we used the following text in a Markdown file:

```md
**한글 bold**
```

With the following font configuration in Zed:

```json
"buffer_font_family": "Victor Mono",
"buffer_font_fallbacks": [
  "D2Coding"
]
```

The fonts can be obtained from their respective locations:

- [Victor Mono](https://rubjo.github.io/victor-mono/)
- [D2Coding](https://github.com/naver/d2codingfont)

This change is motivated by user feedback where we saw some confusion
where they didn't know that you could create either a worktree or branch
through simply typing in their respective picker's editor. Hopefully,
this new placeholder in each of them will help communicate that.

Release Notes:

- Improved placeholder copywriting in both the branch and worktree
pickers to communicate it's possible to type-to-create each.

## Context

GPUI API change only: 
  - added `.alpha(a: f32)` method to `RGBA`
  - added `.opacity(factor: f32)` method to `RGBA`
  - added documentation for both new methods
  - added test coverage for both methods
  
These implementations already exist for the `HSLA` struct and were
missing for `RGBA`.

> [!NOTE]
> In my opinion, a trait implementation could be beneficial here. Let me
know what you think about that idea before I end up making unwanted
changes.

## How to Review

Just added the new methods, including documentation and test coverage.

I asked Claude Fable 5 to review our macOS process spawning layer, and
it found two notable bugs:

- We didn't mark stdio descriptors as inherited when the `Inherit`
option was passed. This means they would be closed in the child due to
`POSIX_SPAWN_DEFAULT_CLOEXEC`. Now we correctly mark them as inherited.
- Child processes were inheriting Rust's default `SIG_IGN` disposition
for `SIGPIPE`. `std::process::Command` resets the disposition to
`SIG_DFL` for children, and this PR makes us do that too, with a
regression test.

Opening a new git worktree of a repository that has a dev container
configuration re-prompted you to reopen in a dev container, even after
you'd clicked "Don't Show Again" in another worktree of the same repo.
The dismissal was keyed on each worktree's own absolute path, so sibling
worktrees never saw the stored choice.

This keys the dismissal on the repository's common Git directory
instead, which is shared across all linked git worktrees of the same
repo, so dismissing in one worktree now suppresses the prompt in the
others. Projects that aren't Git repositories fall back to the worktree
path as before.

Closes AI-357

Release Notes:

- Fixed the "Reopen in Dev Container" suggestion re-appearing in new git
worktrees after choosing "Don't Show Again"
Replaces the verbose struct-literal construction of `gpui::BoxShadow`
with a builder API:

- `BoxShadow::new(offset_x, offset_y, color)` takes the required fields,
with arguments ordered to match the CSS `box-shadow` property.
- `.blur_radius(_)`, `.spread_radius(_)`, and `.inset()` set the
optional fields.

All in-tree call sites are migrated, including the Tailwind-style
`shadow_xs`..`shadow_2xl` helpers in `gpui_macros`, the `ElevationIndex`
shadows in `ui`, and various widgets across `editor`, `workspace`,
`agent_ui`, and `ai_onboarding`. The fields on `BoxShadow` remain
public, so external code using struct-literal construction continues to
work.

…d-industries#59140)

Mermaid diagrams with long node labels rendered as an unreadable jumble:
each label was painted as one long line over a box sized for wrapped
text, overflowing into neighboring nodes. With this change, labels wrap
to the box width the layout computed.

**Root cause:** mermaid's default `htmlLabels: true` makes merman emit
labels as HTML inside `<foreignObject>`, which resvg cannot rasterize.
merman's resvg-safe pipeline replaces each one with a single-line
`<text>` fallback that only honors explicit `<br>` breaks, so
soft-wrapped labels collapse onto one long line — while the node boxes
were laid out for the wrapped text.

**Fix:** disable HTML labels in the site config (both the top-level key,
which merman reads for node labels, and `flowchart.htmlLabels`, which it
reads for edge labels). merman then emits native SVG `<text>`/`<tspan>`
labels wrapped to the same measured width the layout used, and the
foreignObject fallback never runs for these diagrams.

One behavior preserved deliberately: a literal `\n` in label text used
to become a line break as a side effect of the foreignObject fallback
(`fallback.rs` converts `\n` when flattening HTML labels).
`render_mermaid` now normalizes `\n` to `<br/>` before rendering so the
native path keeps that behavior; the existing
`backslash_n_converted_to_line_break` test covers it.

Side effect: class diagram member text also switches from the lossy
fallback to native SVG text; the accent-class test was updated
accordingly (accent classes now land directly on `text`/`tspan`
elements).

Verified with `cargo nextest run -p mermaid_render`, `-p markdown`,
`script/clippy -p mermaid_render`, and `cargo fmt --check`.

Release Notes:

- Fixed mermaid diagram labels overflowing and overlapping nodes when
long labels wrap

# Objective

Give a bit more structure to contributors so that each (potentially new)
contributor doesn't have to come up with their own structure on-the-fly.

## Solution

Update the PR template to include sections for describing

- what the PR is trying to achieve
- how it decided to achieve the goal
- how reviewers can test the work
- demos of the new functionality

## Testing

I used the PR template for this PR, so reviewers can evaluate if they
think the structure is useful.

## Summary

Block / column selection (Shift+Ctrl+drag on Linux, Shift+Cmd+drag on
macOS) anchored its rectangle on a single byte column applied to every
row in the dragged range. On a row whose text contained a multi-byte
character before that column (for example `ã`), the same byte offset
mapped to a different visual `x`, so the per-row cursor drifted off the
column.

`select_columns` now anchors the rectangle in `x` pixels via
`x_for_display_point` and resolves each row's byte column with
`display_column_for_x` — the same pair of helpers already used by
vertical cursor motion and Vim VisualBlock.

## Before / After

**Before** — cursor on the `ã` row drifts one column to the left:

<img width="1068" height="366" alt="image"
src="https://github.com/user-attachments/assets/0559ef89-852e-40f3-9d43-f5f44277f99e"
/>


**After** — rectangle stays visually aligned across rows:

<img width="866" height="408" alt="image"
src="https://github.com/user-attachments/assets/bce13c1a-1ddb-4fd6-8216-2c0e902f6668"
/>


## Test plan

- `cargo test -p editor test_columnar_selection_with_multibyte_chars`
(new regression test covers the buggy case past the `ã` byte boundary,
plus a control case where old and new logic agree).
- Manual: Shift+Ctrl+drag down a five-line buffer where row 3 contains
`ã` — selection rectangle stays aligned (see screenshots).
- Manual: Shift+Alt+drag (`FromSelection` branch) over the same buffer —
same result.
- Manual: drag past EOL on the `ã` row — each row extends to its own EOL
with no panic.

Release Notes:

- Fixed misalignment of column selection on rows that contain multi-byte
characters
