Updating to 2026.3.0-latest has broken my plugin again.

Can anyone help explain what is wrong?

I see this error in the F12 console in Chrome:

```plaintext
app.js:73 Failed to load plugin discourse-directoryopus from https://resource.dopus.com/assets/js/plugins/discourse-directoryopus_main-iafcdugp.digested.js Error: [PLUGIN discourse-directoryopus] Compile error: RollupError: discourse/plugins/discourse-directoryopus/virtual:entrypoint:main (60:12): Duplicate export "discourse$templates$connectors$user __card__ post __names$directoryopus__ link __status__ card$$__module"
    at discourse-directoryopus_main-iafcdugp.digested.js:1:7

```

I think that points back to this file:

> <https://github.com/LeoDavidson/discourse-directoryopus/blob/master/assets/javascripts/discourse/templates/connectors/user-card-post-names/directoryopus-link-status-card.js.es6>

But that hasn’t changed in years, and only exports one thing.

looks like it may be related to this?

> Over the last few months, we’ve been working on a new build system for plugin JavaScript code. This will bring plugins up-to-date with the changes we made to the theme build system back in July 2025, which lean on more modern browser technologies and JS build tooling. This change is largely backwards-compatible. Most plugin authors won’t need to do anything. tadaBenefits As well as the behind-the-scenes modernization, this change will bring a number of functional benefits to Discourse devel…
