Reviewer's GuideWindows legacy command and script recipes now use explicitly selected interpreters: Windows PowerShell by default, or a preflighted Bash compatibility route when requested. Ninja generation serializes each route safely, with PowerShell encoded commands preserving list state and failure semantics; CI smoke coverage, tests, and documentation establish the v0.1.x contract and v0.2.0 structured-command boundary.

Make Windows legacy recipes invoke powershell.exe regardless of the launching shell, while retaining Git Bash/MSYS2 through an explicit NETSUKE_WINDOWS_SHELL=bash compatibility option. Add a pwsh-launched Windows smoke manifest for scalar, list, script, dependency order, quoting, dollar handling, failure, discovery, and missing-runtime diagnostics. Document the v0.1.x and v0.2.0 boundary.
Assert PowerShell dollar-variable handling and Netsuke failure status in the native Windows smoke manifest. Split POSIX recipe validation so the new interpreter selection remains straightforward to maintain.
Keep host-default Windows PowerShell rendering intact while making POSIX structural tests request RecipeShell::Posix directly. This keeps the compatibility renderer covered on every host.
Preserve the explicit POSIX renderer assertion after the backend-dollar escaping rebase, and keep the property module within Whitaker's size limit.

Microsoft PowerShell about automatic variables LASTEXITCODE value last native program
💡 Result:
The $LASTEXITCODE automatic variable in PowerShell contains the exit code of the last native program or PowerShell script that ran [1][2]. Key details regarding its behavior: General Functionality - It serves as the PowerShell equivalent to the %ERRORLEVEL% environment variable found in cmd.exe [3]. - When a native command (an external executable) is executed, PowerShell updates $LASTEXITCODE with the exit code returned by that program [1][3]. - PowerShell also uses this variable to track the exit status of scripts that explicitly use the exit keyword [1][4]. - Related to this is the $? automatic variable, which contains a Boolean value indicating the success ($true) or failure ($false) of the last operation [3]. For native commands, $? is set to $true if $LASTEXITCODE is 0, and $false if it is any other value [2][5]. Behavior in PowerShell Scripts The value of $LASTEXITCODE when running scripts depends on how they are invoked and whether the exit keyword is used [1][2]: - Using the exit keyword: If a script uses the exit keyword, $LASTEXITCODE is set to the value specified by that keyword [1]. - Direct invocation (e.g.,./Test.ps1 or &./Test.ps1): The value is generally not changed unless the script specifically calls a native command, calls another script that uses the exit keyword, or uses the exit keyword itself [1][2]. - Invocation via pwsh with the -File parameter: - Set to 1 if the script terminates due to an exception [1]. - Set to the value specified by the exit keyword if one is used [1]. - Set to 0 if the script completes successfully [1]. - Invocation via pwsh with the -Command parameter: - Set to 1 if the script terminates due to an exception or if the last command set $? to $false [1]. - Set to 0 if the script completes successfully and the last command set $? to $true [1].

Make PowerShell list status checks fail fast per native command.
RecipeShell::command_list_script checks $LASTEXITCODE only after each complete entry. A later successful native command can overwrite an earlier failure within the same entry, so later entries can run. Align the renderer and the guarantees documented in docs/users-guide.md, docs/v0-1-0-migration-guide.md, and docs/developers-guide.md.

Scope the POSIX-only safety rules.
The Windows PowerShell route skips POSIX command-list validation, but the following safety text describes brace groups, eval, background-job limits, and exec rejection without a POSIX/Bash scope. Mark those rules as applying only to Unix and explicit Bash, then document the PowerShell-specific behaviour separately.

💡 Result:
In Rust, the behavior of a std::process::Command concerning stdout and stderr depends on the method used to execute the process. By default, Command is configured to inherit stdin, stdout, and stderr from the parent process [1][2][3]. When using the status method, the child process inherits these streams by default [4]. If you explicitly configure them using.stdout(Stdio::inherit) or.stderr(Stdio::inherit), the child will continue to inherit from the parent's file descriptors [5][6]. If you were to execute, for example, bash --version, the output would be printed directly to your terminal (or whatever stream the parent is using) because the child's stdout is connected to the same stream as the parent's. Summary of Command behaviors: 1. status: By default, inherits stdout/stderr from the parent [4]. 2. spawn: By default, inherits stdout/stderr from the parent [2]. 3. output: By default, captures stdout and stderr (i.e., they are not inherited but rather collected into the Output struct) [1][4]. To force inheritance even when using methods that might otherwise capture them, you can explicitly call.stdout(Stdio::inherit) and.stderr(Stdio::inherit) on the Command instance [5][6].

Suppress output from the Bash availability probe.
validate_recipe_shell runs bash.exe --version before builds and Ninja tool invocations. Command::status() inherits stdout and stderr, so the version banner becomes unsolicited command output. Redirect both streams to Stdio::null().

to Stdio::null() before calling status(), while preserving the existing error
