📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoff
Non-blocking: the fallback heap resolver differs from the canonical helper.
The canonical resolveHeapSizeMb handles the argv percentage and the env percentage in separate branches. If the argv percentage is valid, it is the only percentage used. The fallback handles them together with argvPercentage ?? envPercentage. The results match for valid values.
The fallbacks do differ from the canonical helper in two other ways:
fallbackFindEqualsFlagValuehas no guard against an empty--max-memoryvalue, butfallbackParsePositiveIntegerMbreturnsnullfor it. This matches the canonical helper.- The canonical helper takes
availableBytesandmemorySourcesas inputs. The fallback ignores them. This is acceptable for a launcher-only fallback.
No change is needed. The comment at Lines 17-24 already says the fallbacks must stay in sync. Consider a test that runs both implementations on the same inputs and compares the results. That test would catch future drift.

Node.js fs.symlinkSync Windows omitted type target directory junction privilege requirements documentation
💡 Result:
On current Node.js docs (v26.5.1), `fs.symlinkSync(target, path[, type])` defaults `type` to `null`. On Windows, `null` tells Node to detect the target: it uses `'dir'` or `'file'` if the target exists, and defaults to `'file'` if it does not. So an existing directory target should be detected as a directory; omitting `type` does **not** select a junction. ([nodejs.org](https://nodejs.org/download/release/v26.5.1/docs/api/fs.html))
To explicitly create a junction, pass `'junction'`. Junction targets must be directories; Node normalizes the target to an absolute path. ([nodejs.org](https://nodejs.org/download/release/v26.5.1/docs/api/fs.html))
The Node.js documentation cited here does not specify Windows privilege requirements. It establishes the `type` behavior and path rules, but not whether a particular Windows configuration requires elevation or Developer Mode.

site:learn.microsoft.com Windows symbolic link privilege CreateSymbolicLink junction directory symlink Developer Mode
💡 Result:
Windows distinguishes **symbolic links** from **directory junctions**:
- **Symbolic link:** `CreateSymbolicLink` can create file or directory links. Ordinarily, creating one requires the **Create symbolic links** user right (`SeCreateSymbolicLinkPrivilege`). The API’s `SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE` flag permits creation without an elevated process; Microsoft notes Developer Mode is required for this flag in UWP, but not under MSIX. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows/win32/api/WinBase/nf-winbase-createsymboliclinka?utm_source=openai))
- **Junction:** A directory-to-directory link implemented as a reparse point. It is distinct from a symbolic link; `mklink /J` creates one. The cited Microsoft documentation does not establish that junction creation requires the symbolic-link privilege or Developer Mode. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows/win32/fileio/hard-links-and-junctions?utm_source=openai))
**Bottom line:** Developer Mode is not a blanket requirement for Windows symbolic links. For an unprivileged symbolic link, use the API flag; for a directory junction, use `mklink /J`. The Developer Mode caveat in the API docs specifically names UWP. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows/win32/api/WinBase/nf-winbase-createsymboliclinka?utm_source=openai))

Use a junction and guard the build prerequisite.
On Windows, omitting the symlinkSync type creates a directory symbolic link when dist exists. Creating that link normally requires the symbolic-link privilege. Use a junction instead.
The direct focused-test command does not build dist first, and the launcher exits when dist/cli.mjs is absent. Add a clear prerequisite check. The main CI and release workflows build before running tests, so this is not a CI ordering failure.
