🔴 Critical cli/uninstall.ts:198
The delayed cleanup can delete the wrong directory when runtimeDir contains %NAME%: cmd.exe expands that sequence inside the quoted /c command using the inherited NAME value, so the path passed to rmdir differs from the planned path. Escape % before interpolating runtimeDir (or avoid the shell).

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Handle asynchronous NodeChildProcess.spawn startup errors.
NodeChildProcess is imported from node:child_process. Effect.try does not catch a startup failure emitted through the child’s asynchronous "error" event. The code registers no listener, unrefs the child, and reports success without waiting for startup. The uninstall can leave runtimeDir in place while reporting success. Wait for "spawn" or "error" before reporting success, and map "error" to CliUninstallError.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
Do not interpolate runtimeDir into the cmd.exe command.
--base-dir and T3CODE_HOME reach resolveBaseDir, which only trims and resolves the input. When runtimeDir exists, the Windows branch inserts it into /c after confirmation or --yes. cmd.exe expands %NAME% inside double quotes. A valid directory containing %NAME% can therefore make rmdir delete a different runtime tree. A literal & remains protected by the quotes, but an expansion that supplies a quote can alter command execution.
Pass runtimeDir as opaque data to a detached helper that uses a filesystem API. Do not place the path in the /c command text.

Uninstalling through a symlinked --base-dir skips service.uninstall while still deleting the corresponding runtime directory, leaving the registered service pointing at a removed runtime and broken on its next restart. path.resolve only normalizes path text, so servesThisHome is false when status.installedBaseDir and input.baseDir differ only by symlink components; compare their filesystem-real paths (with an appropriate fallback for missing paths) before deciding whether to uninstall the service.

When ComSpec is unavailable or denied, spawn() emits an asynchronous error event that is unhandled, terminating Node after the service and launcher have already been removed and leaving runtimeDir intact. Effect.try only catches synchronous throws here, so it cannot provide the promised cleanup error handling. Attach an error listener and bridge that event into the Effect failure before returning.

The scheduled Windows cleanup fails when t3.exe is launched from inside <home>/runtime, because the detached cmd.exe inherits that working directory and rmdir cannot remove a directory currently in use by a process. Set the child’s cwd to input.baseDir (outside runtimeDir) before scheduling removal.

Removes what the install script and t3 service install left behind: the background service, the launcher on PATH, and every downloaded version. Shows the plan and asks once; userdata is always kept. Only a launcher that points into this home's runtime tree is removed, so a plain copy of the executable or another install's launcher is left alone. On Windows the runtime tree is deleted by a detached shell after t3 exits, since the executable cannot unlink itself there. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
