-# Rust coding guidelines
-
-* Prioritize code correctness and clarity. Speed and efficiency are secondary priorities unless otherwise specified.
-* Do not write organizational or comments that summarize the code. Comments should only be written in order to explain "why" the code is written in some way in the case there is a reason that is tricky / non-obvious.
-* Prefer implementing functionality in existing files unless it is a new logical component. Avoid creating many small files.
-* Avoid using functions that panic like `unwrap()`, instead use mechanisms like `?` to propagate errors.
-* Be careful with operations like indexing which may panic if the indexes are out of bounds.
-* Never silently discard errors with `let _ =` on fallible operations. Always handle errors appropriately:
-  - Propagate errors with `?` when the calling function should handle them
-  - Use `.log_err()` or similar when you need to ignore errors but want visibility
-  - Use explicit error handling with `match` or `if let Err(...)` when you need custom logic
-  - Example: avoid `let _ = client.request(...).await?;` - use `client.request(...).await?;` instead
-* When implementing async operations that may fail, ensure errors propagate to the UI layer so users get meaningful feedback.
-* Never create files with `mod.rs` paths - prefer `src/some_module.rs` instead of `src/some_module/mod.rs`.
-* When creating new crates, prefer specifying the library root path in `Cargo.toml` using `[lib] path = "...rs"` instead of the default `lib.rs`, to maintain consistent and descriptive naming (e.g., `gpui.rs` or `main.rs`).
-* Avoid creative additions unless explicitly requested
-* Use full words for variable names (no abbreviations like "q" for "queue")
-* Use variable shadowing to scope clones in async contexts for clarity, minimizing the lifetime of borrowed references.
-  Example:
-  ```rust
-  executor.spawn({
-      let task_ran = task_ran.clone();
-      async move {
-          *task_ran.borrow_mut() = true;
-      }
-  });
-  ```
-
-# Timers in tests
-
-* In GPUI tests, prefer GPUI executor timers over `smol::Timer::after(...)` when you need timeouts, delays, or to drive `run_until_parked()`:
-  - Use `cx.background_executor().timer(duration).await` (or `cx.background_executor.timer(duration).await` in `TestAppContext`) so the work is scheduled on GPUI's dispatcher.
-  - Avoid `smol::Timer::after(...)` for test timeouts when you rely on `run_until_parked()`, because it may not be tracked by GPUI's scheduler and can lead to "nothing left to run" when pumping.
-
-# GPUI
-
-GPUI is a UI framework which also provides primitives for state and concurrency management.
-
-## Context
-
-Context types allow interaction with global state, windows, entities, and system services. They are typically passed to functions as the argument named `cx`. When a function takes callbacks they come after the `cx` parameter.
-
-* `App` is the root context type, providing access to global state and read and update of entities.
-* `Context<T>` is provided when updating an `Entity<T>`. This context dereferences into `App`, so functions which take `&App` can also take `&Context<T>`.
-* `AsyncApp` and `AsyncWindowContext` are provided by `cx.spawn` and `cx.spawn_in`. These can be held across await points.
-
-## `Window`
-
-`Window` provides access to the state of an application window. It is passed to functions as an argument named `window` and comes before `cx` when present. It is used for managing focus, dispatching actions, directly drawing, getting user input state, etc.
-
-## Entities
-
-An `Entity<T>` is a handle to state of type `T`. With `thing: Entity<T>`:
-
-* `thing.entity_id()` returns `EntityId`
-* `thing.downgrade()` returns `WeakEntity<T>`
-* `thing.read(cx: &App)` returns `&T`.
-* `thing.read_with(cx, |thing: &T, cx: &App| ...)` returns the closure's return value.
-* `thing.update(cx, |thing: &mut T, cx: &mut Context<T>| ...)` allows the closure to mutate the state, and provides a `Context<T>` for interacting with the entity. It returns the closure's return value.
-* `thing.update_in(cx, |thing: &mut T, window: &mut Window, cx: &mut Context<T>| ...)` takes a `AsyncWindowContext` or `VisualTestContext`. It's the same as `update` while also providing the `Window`.
-
-Within the closures, the inner `cx` provided to the closure must be used instead of the outer `cx` to avoid issues with multiple borrows.
-
-Trying to update an entity while it's already being updated must be avoided as this will cause a panic.
-
-When  `read_with`, `update`, or `update_in` are used with an async context, the closure's return value is wrapped in an `anyhow::Result`.
-
-`WeakEntity<T>` is a weak handle. It has `read_with`, `update`, and `update_in` methods that work the same, but always return an `anyhow::Result` so that they can fail if the entity no longer exists. This can be useful to avoid memory leaks - if entities have mutually recursive handles to each other they will never be dropped.
-
-## Concurrency
-
-All use of entities and UI rendering occurs on a single foreground thread.
-
-`cx.spawn(async move |cx| ...)` runs an async closure on the foreground thread. Within the closure, `cx` is an async context like `AsyncApp` or `AsyncWindowContext`.
-
-When the outer cx is a `Context<T>`, the use of `spawn` instead looks like `cx.spawn(async move |handle, cx| ...)`, where `handle: WeakEntity<T>`.
-
-To do work on other threads, `cx.background_spawn(async move { ... })` is used. Often this background task is awaited on by a foreground task which uses the results to update state.
-
-Both `cx.spawn` and `cx.background_spawn` return a `Task<R>`, which is a future that can be awaited upon. If this task is dropped, then its work is cancelled. To prevent this one of the following must be done:
-
-* Awaiting the task in some other async context.
-* Detaching the task via `task.detach()` or `task.detach_and_log_err(cx)`, allowing it to run indefinitely.
-* Storing the task in a field, if the work should be halted when the struct is dropped.
-
-A task which doesn't do anything but provide a value can be created with `Task::ready(value)`.
-
-## Elements
-
-The `Render` trait is used to render some state into an element tree that is laid out using flexbox layout. An `Entity<T>` where `T` implements `Render` is sometimes called a "view".
-
-Example:
-
-```
-struct TextWithBorder(SharedString);
-
-impl Render for TextWithBorder {
-    fn render(&mut self, _window: &mut Window, _cx: &mut Context<Self>) -> impl IntoElement {
-        div().border_1().child(self.0.clone())
-    }
-}
-```
-
-Since `impl IntoElement for SharedString` exists, it can be used as an argument to `child`. `SharedString` is used to avoid copying strings, and is either an `&'static str` or `Arc<str>`.
-
-UI components that are constructed just to be turned into elements can instead implement the `RenderOnce` trait, which is similar to `Render`, but its `render` method takes ownership of `self`. Types that implement this trait can use `#[derive(IntoElement)]` to use them directly as children.
-
-The style methods on elements are similar to those used by Tailwind CSS.
-
-If some attributes or children of an element tree are conditional, `.when(condition, |this| ...)` can be used to run the closure only when `condition` is true. Similarly, `.when_some(option, |this, value| ...)` runs the closure when the `Option` has a value.
-
-## Input events
-
-Input event handlers can be registered on an element via methods like `.on_click(|event, window, cx: &mut App| ...)`.
-
-Often event handlers will want to update the entity that's in the current `Context<T>`. The `cx.listener` method provides this - its use looks like `.on_click(cx.listener(|this: &mut T, event, window, cx: &mut Context<T>| ...)`.
-
-## Actions
-
-Actions are dispatched via user keyboard interaction or in code via `window.dispatch_action(SomeAction.boxed_clone(), cx)` or `focus_handle.dispatch_action(&SomeAction, window, cx)`.
-
-Actions with no data defined with the `actions!(some_namespace, [SomeAction, AnotherAction])` macro call. Otherwise the `Action` derive macro is used. Doc comments on actions are displayed to the user.
-
-Action handlers can be registered on an element via the event handler `.on_action(|action, window, cx| ...)`. Like other event handlers, this is often used with `cx.listener`.
-
-## Notify
-
-When a view's state has changed in a way that may affect its rendering, it should call `cx.notify()`. This will cause the view to be rerendered. It will also cause any observe callbacks registered for the entity with `cx.observe` to be called.
-
-## Entity events
-
-While updating an entity (`cx: Context<T>`), it can emit an event using `cx.emit(event)`. Entities register which events they can emit by declaring `impl EventEmittor<EventType> for EntityType {}`.
-
-Other entities can then register a callback to handle these events by doing `cx.subscribe(other_entity, |this, other_entity, event, cx| ...)`. This will return a `Subscription` which deregisters the callback when dropped.  Typically `cx.subscribe` happens when creating a new entity and the subscriptions are stored in a `_subscriptions: Vec<Subscription>` field.
-
-## Recent API changes
-
-GPUI has had some changes to its APIs. Always write code using the new APIs:
-
-* `spawn` methods now take async closures (`AsyncFn`), and so should be called like `cx.spawn(async move |cx| ...)`.
-* Use `Entity<T>`. This replaces `Model<T>` and `View<T>` which no longer exist and should NEVER be used.
-* Use `App` references. This replaces `AppContext` which no longer exists and should NEVER be used.
-* Use `Context<T>` references. This replaces `ModelContext<T>` which no longer exists and should NEVER be used.
-* `Window` is now passed around explicitly. The new interface adds a `Window` reference parameter to some methods, and adds some new "*_in" methods for plumbing `Window`. The old types `WindowContext` and `ViewContext<T>` should NEVER be used.

+## Problem
+
+PR #44810 causes Zed to hang on startup on Linux/Windows, but works fine on Mac.
+
+From PR comment by @yara-blue and @localcc:
+> "With it applied zed hangs without ever responding when you open it"
+
+## What Was Cleaned Up
+
+Removed unrelated changes that were accidentally committed:
+- `ConfiguredApiCard`, `InstructionListItem`, `api_key.rs` (UI components)
+- Debug instrumentation in `terminal_tool.rs`, `capability_granter.rs`, `wasm_host/wit/since_v0_8_0.rs`, `lsp_store.rs`
+- Planning docs (`.rules`, `PLAN.md`, old `STATUS.md`)
+
+Kept `language_registry.rs` changes as they may be relevant to debugging.
+
+## Analysis So Far
+
+### Code paths verified as correct:
+
+1. **Priority queue algorithm** - The weighted random selection in `crates/gpui/src/queue.rs` is mathematically sound. When the last non-empty queue is checked, the probability is always 100%.
+
+2. **`async_task::Task` implements `Unpin`** - So `Pin::new(task).poll(cx)` is valid.
+
+3. **`parking::Parker` semantics** - If `unpark()` is called before `park()`, the `park()` returns immediately. This is correct.
+
+4. **Waker creation** - `waker_fn` with `Unparker` (which is `Clone + Send + Sync`) should work correctly.
+
+5. **`PlatformScheduler::block` implementation** - Identical logic to the old `block_internal` for production builds.
+
+### The blocking flow:
+
+1. Task spawned → runnable scheduled → sent to priority queue
+2. Background thread waiting on condvar in `PriorityQueueReceiver::recv()`
+3. `send()` pushes to queue and calls `condvar.notify_one()`
+4. Background thread wakes, pops item, runs runnable
+5. When task completes, `async_task` wakes the registered waker
+6. Waker calls `unparker.unpark()`
+7. `parker.park()` returns
+8. Future is polled again, returns `Ready`
+
+### Files involved:
+
+- `crates/gpui/src/platform_scheduler.rs` - `PlatformScheduler::block()` implementation
+- `crates/gpui/src/executor.rs` - `BackgroundExecutor::block()` wraps futures
+- `crates/gpui/src/queue.rs` - Priority queue with `parking_lot::Condvar`
+- `crates/gpui/src/platform/linux/dispatcher.rs` - Background thread pool
+- `crates/scheduler/src/executor.rs` - `scheduler::BackgroundExecutor::spawn_with_priority`
+
+## What to investigate next
+
+### 1. Verify background threads are actually running
+
+Add logging at the start of background worker threads in `LinuxDispatcher::new()`:
+```rust
+.spawn(move || {
+    log::info!("[LinuxDispatcher] background worker {} started", i);
+    for runnable in receiver.iter() {
+        // ...
+    }
+})
+```
+
+### 2. Verify tasks are being dispatched
+
+Add logging in `PlatformScheduler::schedule_background_with_priority`:
+```rust
+fn schedule_background_with_priority(&self, runnable: Runnable<RunnableMeta>, priority: Priority) {
+    log::info!("[PlatformScheduler] dispatching task priority={:?}", priority);
+    self.dispatcher.dispatch(runnable, priority);
+}
+```
+
+### 3. Verify the priority queue send/receive
+
+In `crates/gpui/src/queue.rs`, add logging to `send()` and `recv()`:
+```rust
+fn send(&self, priority: Priority, item: T) -> Result<(), SendError<T>> {
+    // ...
+    self.condvar.notify_one();
+    log::debug!("[PriorityQueue] sent item, notified condvar");
+    Ok(())
+}
+
+fn recv(&self) -> Result<...> {
+    log::debug!("[PriorityQueue] recv() waiting...");
+    while queues.is_empty() {
+        self.condvar.wait(&mut queues);
+    }
+    log::debug!("[PriorityQueue] recv() got item");
+    // ...
+}
+```
+
+### 4. Check timing of dispatcher creation vs task spawning
+
+Trace when `LinuxDispatcher::new()` is called vs when the first `spawn()` happens. If tasks are spawned before background threads are ready, they might be lost.
+
+### 5. Check for platform-specific differences in `parking` or `parking_lot`
+
+The `parking` crate (used for `Parker`/`Unparker`) and `parking_lot` (used for `Condvar` in the priority queue) may have platform-specific behavior. Check their GitHub issues for Linux-specific bugs.
+
+### 6. Verify the startup sequence
+
+The hang happens during startup. Key calls in `crates/zed/src/main.rs`:
+```rust
+// Line ~292: Tasks spawned BEFORE app.run()
+let system_id = app.background_executor().spawn(system_id());
+let installation_id = app.background_executor().spawn(installation_id());
+let session = app.background_executor().spawn(Session::new(session_id.clone()));
+
+// Line ~513-515: Inside app.run() callback, these BLOCK waiting for the tasks
+let system_id = cx.background_executor().block(system_id).ok();
+let installation_id = cx.background_executor().block(installation_id).ok();
+let session = cx.background_executor().block(session);
+```
+
+If background threads aren't running yet when `block()` is called, or if the tasks never got dispatched, it will hang forever.
+
+## Hypotheses to test
+
+1. **Background threads not started yet** - Race condition where tasks are dispatched before threads are listening on the queue.
+
+2. **Condvar notification lost** - `notify_one()` called but no thread was waiting yet, and subsequent waits miss it.
+
+3. **Platform-specific parking behavior** - `parking::Parker` or `parking_lot::Condvar` behaves differently on Linux.
+
+4. **Priority queue never releases items** - Something in the weighted random selection is wrong on Linux (different RNG behavior?).
+
+## Running tests
+
+To get logs, set `RUST_LOG=info` or `RUST_LOG=debug` when running Zed.
+
+For the extension_host test hang (separate issue):
+```bash
+cargo test -p extension_host extension_store_test::test_extension_store_with_test_extension -- --nocapture
+```
+
+## Key commits
+
+- `5b07e2b242` - "WIP: scheduler integration debugging" - This accidentally added unrelated UI components
+- `d8ebd8101f` - "WIP: scheduler integration debugging + agent terminal diagnostics" - Added debug instrumentation (now removed)
