License question: reusing memory-core (and the kibitzer recall persona) in an open-source app with paid credits

[leetae9yu]

Hi, thanks for building oh-my-openagent. I use it daily and the memory system is a big part of why.

I'm building an assistant app for university students that works with their LMS (courses, assignments, deadlines). I plan to publish the app's source code as open source, and run a hosted version where users buy usage credits to cover model costs.

I would like to reuse the memory logic from this repo, mainly packages/memory-core (including the recall flow and src/recall/assets/kibitzer-persona.md).

As I read LICENSE.md, everything outside third-party components is under the Sustainable Use License 1.0. packages/memory-core has no separate license file, and its package.json has no license field. Under SUL-1.0, distribution is allowed only free of charge for non-commercial purposes, so I don't think a credit-based hosted service could include this code as it is.

My questions:

1. Is my reading right that packages/memory-core is covered by SUL-1.0, not by MIT like senpi?
2. Would you consider granting permission, or a separate license (for example MIT or a commercial license), for using memory-core in an open-source app that charges for usage credits? If there are terms, I'm happy to hear them.
3. If neither is possible, is it acceptable to write my own implementation that follows the same general design ideas (memory blocks, recall, consent handling) without copying code or prompt text?

I'll keep all license and copyright notices and mark any modifications, whatever the answer is. Thank you!

A clarification on how the app would make money, since it affects the "commercial" question:

• Paid credits would only cover services I run on the user's behalf, such as speech-to-text (STT) for lecture recordings.
• The rest of the app, including the course and assignment management features, would be mostly free, or users would sign in with their own accounts through OAuth and use their own model access.

The whole app, including any part that uses memory-core, will be fully open source, with its source code public.

So the memory logic itself would not be sold or charged for directly, but it would ship inside an app that has paid STT credits. I'd like to know whether that setup is acceptable under the license, or what you would need from me.
