 The `bx` will build just the Terminal package, critically, populating the `CascadiaPackage.build.appxrecipe` file. Once that's been built, then the `DeployAppRecipe.exe` command can be used to deploy a loose layout in the same way that Visual Studio does.

 be even better, as a way of making the meaning of the "list of actions" more
 obvious.
 
-When we're parsing `actions`, we'll make three passes:
-* The first pass will scan the list for objects with an `id` property. We'll
+We will then restructure `defaults.json`, and also users' settings files (via `fixUpUserSettings`), in the following manner:
+* Instead of each `command` json block containing both the `action` (along with additional arguments) and the `keys`, these will now be split up -
+    * There will now be one json block for just the `command`/`action`, which will also contain the `id`. These json blocks will be in their own list called `actions`.
+    * There will be another json block for the `keys`, which will refer to the action to be invoked by `id`. These json blocks will be in their own list called `keybindings`.
+
+For example, let's take a look at the `split pane right` action in `defaults.json` as we currently have it:
+
+`"actions": [..., { "command": { "action": "splitPane", "split": "right" }, "keys": "alt+shift+plus" }, ...]`
+
+This will now become:
+
+`"actions": [..., { "command": { "action": "splitPane", "split": "right" }, "id": "Terminal.SplitPaneRight" }, ...]`
+
+`"keybindings": [..., { "keys": "alt+shift+plus", "id": "Terminal.SplitPaneRight" }, ...]`
+
+Here is how we will parse settings file and construct the relevant settings model objects:
+* We will first scan the `actions` list. We'll
   attempt to parse those entries into `ActionAndArgs` which we'll store in the
-  global `id->ActionAndArgs` map. If any entry doesn't have an `id` set, we'll
-  skip it in this phase. If an entry doesn't have a `command` set, we'll ignore
-  it in this pass.
-* The second pass will scan for _keybindings_. Any entries with `keys` set will
-  create a `KeyChord->ActionAndArgs` entry in the keybindings map. If the entry
-  has an `id` set, then we'll simply re-use the action we've already parsed for
-  the `id`, from the action map. If there isn't an `id`, then we'll parse the
-  action manually at this time. Entries without a `keys` set will be ignored in
-  this pass.
-* The final pass will be to generate _commands_. Similar to the keybindings
-  pass, we'll attempt to lookup actions for entries with an `id` set. If there
-  isn't an `id`, then we'll parse the action manually at this time. We'll then
-  get the name for the entry, either from the `name` property if it's set, or
-  the action's `GenerateName` method.
+  global `id->ActionAndArgs` map. All actions defined in `defaults.json` must have an `id` specified, and all actions provided by fragments must also have `id`s. Any actions from the defaults or fragments that do not provide `id`s will be ignored. As for user-specified commands, if no `id` is set, we will auto-generate one for that command based on the action and any additional arguments. For example, the `split pane right` command above might result in an autogenerated id `User.SplitPaneRight`.
+    * Note: this step is also where we will generate _commands_. We will use the name provided in the entry if it's set or the action's `GenerateName` method.
+* Next we will scan the `keybindings` list. These entries will
+  create a `KeyChord->ActionAndArgs` entry in the keybindings map. Since these objects should all contain an `id`, we will simply use the `id->ActionAndArgs` map we created in the previous step. Any object with `keys` set but no `id` will be ignored.

+
+# Console Allocation Policy
+
+## Abstract
+
+Due to the design of the console subsystem on Windows as it has existed since Windows 95, every application that is
+stamped with the `IMAGE_SUBSYSTEM_WINDOWS_CUI` subsystem in its PE header will be allocated a console by kernel32.
+
+Any application that is stamped `IMAGE_SUBSYSTEM_WINDOWS_GUI` will not automatically be allocated a console.
+
+This has worked fine for many years: when you double-click a console application in your GUI shell, it is allocated a
+console.  When you run a GUI application from your console shell, it is **not** allocated a console. The shell will
+**not** wait for it to exit before returning you to a prompt.
+
+There is a large class of applications that do not fit neatly into this mold. Take Python, Ruby, Perl, Lua, or even
+VBScript: These languages are not relegated to running in a console session; they can be used to write fully-fledged GUI
+applications like any other language.
+
+Because their interpreters are console subsystem applications, however, any user double-clicking a shortcut to a Python
+or Perl application will be presented with a console window that the language runtime may choose to garbage collect, or
+may choose not to.
+
+If the runtime chooses to hide the window, there will still be a brief period during which that window is visible. It is
+inescapable.
+
+Likewise, any user running that GUI application from a console shell will see their shell hang until the application
+terminates.
+
+All of these scripting languages worked around this by shipping two binaries each, identical in every way expect in
+their subsystem fields. python/pythonw, perl/perlw, ruby/rubyw, wscript/cscript.
+
+PowerShell[^1] is waiting to deal with this problem because they don't necessarily want to ship a `pwshw.exe` for all
+of their GUI-only authors. Every additional `*w` version of an application is an additional maintenance burden and
+source of cognitive overhead[^2] for users.
+
+On the other side, you have mostly-GUI applications that want to print output to a console **if there is one
+connected**.
+
+These applications are still primarily GUI-driven, but they might support arguments like `/?` or `--help`. They only
+need a console when they need to print out some text. Sometimes they'll allocate their own console (which opens a new
+window) to display in, and sometimes they'll reattach to the originating console. VSCode does the latter, and so when
+you run `code` from CMD, and then `exit` CMD, your console window sticks around because VSCode is still attached to it.
+It will never print anything, and your only option is to close it.
+
+There's another risk in reattaching, too. Given that the shell decides whether to wait based on the subsystem
+field, GUI subsystem applications that reattach to their owning consoles *just to print some text* end up stomping on
+the output of any shell that doesn't wait for them:
+
+```
+C:\> application --help
+
+application - the interesting application
+C:\> Usage: application [OPTIONS] ...
+```
+
+> _(the prompt is interleaved with the output)_
+
+## Solution Design
+
+I propose that we introduce a fusion manifest field, **consoleAllocationPolicy**, with the following values:
+
+* _absent_
+* `detached`
+
+This field allows an application to disable the automatic allocation of a console, regardless of the [process creation flags]
+passed to [`CreateProcess`] and its subsystem value.
+
+It would look (roughly) like this:
+
+```xml
+<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
+<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
+  <application>
+    <windowsSettings>
+      <consoleAllocationPolicy xmlns="http://schemas.microsoft.com/SMI/2024/WindowsSettings">detached</consoleAllocationPolicy>
+    </windowsSettings>
+  </application>
+</assembly>
+```
+
+The effects of this field will only apply to binaries in the `IMAGE_SUBSYSTEM_WINDOWS_CUI` subsystem, as it pertains to
+the particulars of their console allocation.
+
+**All console inheritance will proceed as normal.** Since this field takes effect only in the absence of console
+inheritance, CUI applications will still be able to run inside an existing console session.
+
+| policy     | behavior                                                                                                            |
+| -          | -                                                                                                                   |
+| _absent_   | _default behavior_                                                                                                  |
+| `detached` | The new process is not attached to a console session (similar to `DETACHED_PROCESS`) unless one was inherited.      |
+
+An application that specifies the `detached` allocation policy will _not_ present a console window when launched by
+Explorer, Task Scheduler, etc.
+
+### Interaction with existing APIs
+
+[`CreateProcess`] supports a number of [process creation flags] that dictate how a spawned application will behave with
+regards to console allocation:
+
+* `DETACHED_PROCESS`: No console inheritance, no console host spawned for the new process.
+* `CREATE_NEW_CONSOLE`: No console inheritance, new console host **is** spawned for the new process.
+* `CREATE_NO_WINDOW`: No console inheritance, new console host **is** spawned for the new process.
+    * this is the same as `CREATE_NEW_CONSOLE`, except that the first connection packet specifies that the window should
+      be invisible
+
+Due to the design of [`CreateProcess`] and `ShellExecute`, this specification recommends that an allocation policy of
+`detached` _override_ the inclusion of `CREATE_NEW_CONSOLE` in the `dwFlags` parameter to [`CreateProcess`].
+
+> **Note**
+> `ShellExecute` passes `CREATE_NEW_CONSOLE` _by default_ on all invocations. This impacts our ability to resolve the
+> conflicts between these two APIs--`detached` policy and `CREATE_NEW_CONSOLE`--without auditing every call site in
+> every Windows application that calls `ShellExecute` on a console application. Doing so is infeasible.
+
+### Application impact
+
+An application that opts into the `detached` console allocation policy will **not** be allocated a console unless one is
+inherited. This presents an issue for applications like PowerShell that do want a console window when they are launched
+directly.
+
+Applications in this category can call `AllocConsole()` early in their startup to get fine-grained control over when a
+console is presented.
+
+The call to `AllocConsole()` will fail safely if the application has already inherited a console handle. It will succeed
+if the application does not currently have a console handle.
+
+> **Note**
+> **Backwards Compatibility**: The behavior of `AllocConsole()` is not changing in response to this specification;
+> therefore, applications that intend to run on older versions of Windows that do not support console allocation
+> policies, which call `AllocConsole()`, will continue to behave normally.
+
+### New APIs
+
+Because a console-subsystem application may still want fine-grained control over when and how its console window is
+spawned, we propose the inclusion of a new API, `AllocConsoleWithOptions(PALLOC_CONSOLE_OPTIONS)`.
+
+#### `AllocConsoleWithOptions`
+
+```c++
+// Console Allocation Modes
+typedef enum ALLOC_CONSOLE_MODE {
+    ALLOC_CONSOLE_MODE_DEFAULT    = 0,
+    ALLOC_CONSOLE_MODE_NEW_WINDOW = 1,
+    ALLOC_CONSOLE_MODE_NO_WINDOW  = 2
+} ALLOC_CONSOLE_MODE;
+
+typedef enum ALLOC_CONSOLE_RESULT {
+    ALLOC_CONSOLE_RESULT_NO_CONSOLE       = 0,
+    ALLOC_CONSOLE_RESULT_NEW_CONSOLE      = 1,
+    ALLOC_CONSOLE_RESULT_EXISTING_CONSOLE = 2
+} ALLOC_CONSOLE_RESULT, *PALLOC_CONSOLE_RESULT;
+
+typedef
+struct ALLOC_CONSOLE_OPTIONS
+{
+    ALLOC_CONSOLE_MODE mode;
+    BOOL useShowWindow;
+    WORD showWindow;
+} ALLOC_CONSOLE_OPTIONS, *PALLOC_CONSOLE_OPTIONS;
+
+WINBASEAPI
+HRESULT
+WINAPI
+AllocConsoleWithOptions(_In_opt_ PALLOC_CONSOLE_OPTIONS allocOptions, _Out_opt_ PALLOC_CONSOLE_RESULT result);
+```
+
+**AllocConsoleWithOptions** affords an application control over how and when it begins a console session.
+
+> [!NOTE]
+> Unlike `AllocConsole`, `AllocConsoleWithOptions` without a mode (`ALLOC_CONSOLE_MODE_DEFAULT`) will only allocate a console if one was
+> requested during `CreateProcess`.
+>
+> To override this behavior, pass one of `ALLOC_CONSOLE_MODE_NEW_WINDOW` (which is equivalent to being spawned with
+> `CREATE_NEW_WINDOW`) or `ALLOC_CONSOLE_MODE_NO_WINDOW` (which is equivalent to being spawned with `CREATE_NO_CONSOLE`.)
+
+##### Parameters
+
+**allocOptions**: A pointer to a `ALLOC_CONSOLE_OPTIONS`.
+
+**result**: An optional out pointer, which will be populated with a member of the `ALLOC_CONSOLE_RESULT` enum.
+
+##### `ALLOC_CONSOLE_OPTIONS`
+
+###### Members
+
+**mode**: See the table below for the descriptions of the available modes.
+
+**useShowWindow**: Specifies whether the value in `showWindow` should be used.
+
+**showWindow**: If `useShowWindow` is set, specifies the ["show command"] used to display your
+console window.
+
+###### Return Value
+
+`AllocConsoleWithOptions` will return `S_OK` and populate `result` to indicate whether--and how--a console session was
+created.
+
+`AllocConsoleWithOptions` will return a failing `HRESULT` if the request could not be completed.
+
+###### Modes
+
+|             Mode                | Description                                                                                                                    |
+|:-------------------------------:| ------------------------------------------------------------------------------------------------------------------------------ |
+| `ALLOC_CONSOLE_MODE_DEFAULT`    | Allocate a console session if (and how) one was requested by the parent process.                                               |
+| `ALLOC_CONSOLE_MODE_NEW_WINDOW` | Allocate a console session with a window, even if this process was created with `CREATE_NO_CONSOLE` or `DETACHED_PROCESS`.     |
+| `ALLOC_CONSOLE_MODE_NO_WINDOW`  | Allocate a console session _without_ a window, even if this process was created with `CREATE_NEW_WINDOW` or `DETACHED_PROCESS` |
+
+###### Notes
+
+Applications seeking backwards compatibility are encouraged to delay-load `AllocConsoleWithOptions` or check for its presence in
+the `api-ms-win-core-console-l1` APISet.
+
+## Inspiration
+
+Fusion manifest entries are used to make application-scoped decisions like this all the time, like `longPathAware` and
+`heapType`.
+
+CUI applications that can spawn a UI (or GUI applications that can print to a console) are commonplace on other
+platforms because there is no subsystem differentiation.
+
+## UI/UX Design
+
+There is no UI for this feature.
+
+## Capabilities
+
+### Accessibility
+
+This should have no impact on accessibility.
+
+### Security
+
+One reviewer brought up the potential for a malicious actor to spawn an endless stream of headless daemon processes.
+
+This proposal in no way changes the facilities available to malicious people for causing harm: they could have simply
+used `IMAGE_SUBSYSTEM_WINDOWS_GUI` and not presented a UI--an option that has been available to them for 35 years.
+
+### Reliability
+
+This should have no impact on reliability.
+
+### Compatibility
+
+An existing application opting into **detached** may constitute a breaking change, but the scope of the breakage is
+restricted to that application and is expected to be managed by the application.
+
+All behavioral changes are opt-in.
+
+> **EXAMPLE**: If Python updates python.exe to specify an allocation policy of **detached**, graphical python applications
+> will become double-click runnable from the graphical shell without spawning a console window. _However_, console-based
+> python applications will no longer spawn a console window when double-clicked from the graphical shell.
+>
+> In addition, if python.exe specifies **detached**, Console APIs will fail until a console is allocated.
+
+Python could work around this by calling [`AllocConsole`] or [new API `AllocConsoleWithOptions`](#allocconsolewithoptions)
+if it can be detected that console I/O is required.
+
+#### Downlevel
+
+On downlevel versions of Windows that do not understand (or expect) this manifest field, applications will allocate
+consoles as specified by their image subsystem (described in the [abstract](#abstract) above).
+
+### Performance, Power, and Efficiency
+
+This should have no impact on performance, power or efficiency.
+
+## Potential Issues
+
+### Shell Hang
+
+I am **not** proposing a change in how shells determine whether to wait for an application before returning to a prompt.
+This means that a console subsystem application that intends to primarily present a UI but occasionally print text to a
+console (therefore choosing the **detached** allocation policy) will cause the shell to "hang" and wait for it to
+exit.
+
+The decision to pause/wait is made entirely in the calling shell, and the console subsystem cannot influence that
+decision.
+
+Because the vast majority of shells on Windows "hang" by calling `WaitFor...Object` with a HANDLE to the spawned
+process, an application that wants to be a "hybrid" CUI/GUI application will be forced to spawn a separate process to
+detach from the shell and then terminate its main process.
+
+This is very similar to the forking model seen in many POSIX-compliant operating systems.
+
+### Launching interactively from Explorer, Task Scheduler, etc.
+
+Applications like PowerShell may wish to retain automatic console allocation, and **detached** would be unsuitable for
+them. If PowerShell specifies the `detached` console allocation policy, launching `pwsh.exe` from File Explorer it will
+no longer spawn a console. This would almost certainly break PowerShell for all users.
+
+Such applications can use `AllocConsole()` early in their startup.
+
+At the same time, PowerShell wants `-WindowStyle Hidden` to suppress the console _before it's created_.
+
+Applications in this category can use `AllocConsoleWithOptions()` to specify additional information about the new console window.
+
+PowerShell, and any other shell that wishes to maintain interactive launch from the graphical shell, can start in
+**detached** mode and then allocate a console as necessary. Therefore:
+
+* PowerShell will set `<consoleAllocationPolicy>detached</consoleAllocationPolicy>`
+* On startup, it will process its commandline arguments.
+* If `-WindowStyle Hidden` is **not** present (the default case), it can:
+   * `AllocConsole()` or `AllocConsoleWithOptions(NULL)`
+   * Either of these APIs will present a console window (or not) based on the flags passed through `STARTUPINFO` during
+     [`CreateProcess`].
+* If `-WindowStyle Hidden` is present, it can:
+   * `AllocConsoleWithOptions(&alloc)` where `alloc.mode` specifies `ALLOC_CONSOLE_MODE_HIDDEN`
+
+## Future considerations
+
+We're introducing a new manifest field today -- what if we want to introduce more? Should we have a `consoleSettings`
+manifest block?
+
+Are there other allocation policies we need to consider?
+
+## Resources
+
+### Rejected Solutions
+
+- A new PE subsystem, `IMAGE_SUBSYSTEM_WINDOWS_HYBRID`
+    - it would behave like **inheritOnly**
+    - relies on shells to update and check for this
+    - checking a subsystem doesn't work right with app execution aliases[^3]
+        - This is not a new problem, but it digs the hole a little deeper.
+    - requires standardization outside of Microsoft because the PE format is a dependency of the UEFI specification[^4]
+    - requires coordination between tooling teams both within and without Microsoft (regarding any tool that operates on
+      or produces PE files)
+
+- An exported symbol that shells can check for to determine whether to wait for the attached process to exit
+    - relies on shells to update and check for this
+    - cracking an executable to look for symbols is probably the last thing shells want to do
+        - we could provide an API to determine whether to wait or return?
+    - fragile, somewhat silly, exporting symbols from EXEs is annoying and uncommon
+
+An earlier version of this specification offered the **always** allocation policy, with the following behaviors:
+
+> **STRUCK FROM SPECIFICATION**
+>
+> * A GUI subsystem application would always get a console window.
+> * A command-line shell would not wait for it to exit before returning a prompt.
+
+It was cut because a GUI application that wants a console window can simply attach to an existing console session or
+allocate a new one. We found no compelling use case that would require the forced allocation of a console session
+outside of the application's code.
+
+An earlier version of this specification offered the **inheritOnly** allocation policy, instead of the finer-grained
+**hidden** and **detached** policies. We deemed it insufficient for PowerShell's use case because any application
+launched by an **inheritOnly** PowerShell would immediately force the uncontrolled allocation of a console window.
+
+> **STRUCK FROM SPECIFICATION**
+>
+> The move to **hidden** allows PowerShell to offer a fully-fledged console connection that can be itself inherited by a
+> downstream application.
+
+#### Additional allocation policies
+
+An earlier revision of this specification suggested two allocation policies:
+
+> **STRUCK FROM SPECIFICATION**
+>
+> **hidden** is intended to be used by console applications that want finer-grained control over the visibility of their
+> console windows, but that still need a console host to service console APIs. This includes most scripting language
+> interpreters.
+>
+> **detached** is intended to be used by primarily graphical applications that would like to operate against a console _if
+> one is present_ but do not mind its absence. This includes any graphical tool with a `--help` or `/?` argument.
+
+The `hidden` policy was rejected due to an incompatibility with modern console hosting, as `hidden` would require an
+application to interact with the console window via `GetConsoleWindow()` and explicitly show it.
+
+> **STRUCK FROM SPECIFICATION**
+>
+> ##### ShowWindow and ConPTY
+>
+> The pseudoconsole creates a hidden window to service `GetConsoleWindow()`, and it can be trivially shown using
+> `ShowWindow`. If we recommend that applications `ShowWindow` on startup, we will need to guard the pseudoconsole's
+> pseudo-window from being shown.

+
+Abstract:
+- Definitions for types that are used for "scroll marks" and shell integration
+  in the buffer.
+- Scroll marks are identified by the existence of "ScrollbarData" on a ROW in the buffer.
+- Shell integration will then also markup the buffer with special
+  TextAttributes, to identify regions of text as the Prompt, the Command, the
+  Output, etc.
+- MarkExtents are used to abstract away those regions of text, so a caller
+  doesn't need to iterate over the buffer themselves.
