### Category of the issue

No applicable update found.

### Brief description of your issue

Version 0.4.0 of `Nirosoftware.SerialFlow` was merged via #398571 on 2026-07-06 (labels: Azure-Pipeline-Passed, Validation-Completed, Moderator-Approved, Publish-Pipeline-Succeeded; wingetbot posted "Publish pipeline succeeded for this Pull Request"). Four days later the community source still does not serve 0.4.0 — `winget show --versions` lists only 0.1.1 and a versioned install fails, even immediately after `winget source update`.

The 0.4.0 manifests are present in master under `manifests/n/Nirosoftware/SerialFlow/0.4.0` and are structurally identical to the indexed 0.1.1 manifests (only version/URL/SHA256 differ). There are no revert commits touching this path and no related issues that I could find. The installer is a signed portable exe (Azure Trusted Signing); the InstallerSha256 matches the published release asset.

I'm the publisher. It looks like the version was dropped somewhere between the publish pipeline and the served index — could you check why 0.4.0 was never indexed (or delisted post-publish), and restore it?

### Steps to reproduce

1. `winget source update`
2. `winget show --id Nirosoftware.SerialFlow --exact --versions --accept-source-agreements`
3. `winget install --id Nirosoftware.SerialFlow --exact --version 0.4.0 --accept-source-agreements --accept-package-agreements`

### Actual behavior

Step 2 lists only:

```
Version
-------
0.1.1
```

Step 3 fails with `No version found matching: 0.4.0`.

### Expected behavior

0.4.0 is listed and installable (it was merged, validated, moderator-approved, and the publish pipeline reported success on 2026-07-06, #398571).

### Environment

```
winget v1.29.280
Windows 10/11 x64 (default winget community source)
Package: Nirosoftware.SerialFlow 0.4.0, merged in #398571
```

Start with the manifests in manifests/n/Nirosoftware/SerialFlow/0.4.0 and the publish result from pull request #398571. Reproduce with winget source update, winget show --id Nirosoftware.SerialFlow --exact --versions, and the versioned install command; done means version 0.4.0 is listed and installable from the community source.
