Basic chat implementation

This is not yet a real time chat implementation, but it works.

The chat creator is an actor that can create new chats.

A chat is an entity that offers the affordance of creating a participation.

A participation is like an invite link that's associated with a name.

Anyone who has a participation URL can submit messages under that name.

I've also changed some various things in the actor framework.

It's still a work in progress and this is the first real feature
that involves multiple participants and so on.

The next thing to add is real-time updates which I'm still thinking about.

I'll write about that in a note.

+This chat system reimagines how people can communicate online by building entirely on capability-based security principles instead of traditional user accounts. When someone creates a chat room, they receive a special URL that grants them the power to create "participations." Each participation manifests as a unique URL that enables sending messages under a specific name in that chat.
+
+The system works through simple URL sharing rather than accounts and passwords. To add someone to a chat, the creator generates a participation URL for a chosen name and shares it through any preferred channel. Anyone with that URL can then send messages appearing under that name, and if multiple people have the same URL, they'll all appear as that participant. This eliminates the need for user authentication while maintaining a clean way to manage who can speak and under what names.
+
+The design extends naturally to delegation of capabilities. Chat creators can generate delegate URLs that grant others limited power to create new participations. These delegate capabilities can be constrained in various ways - allowing someone to add only a specific number of participants, create temporary participations that expire, or add participants matching certain name patterns. All security and permissions are embedded in the URLs themselves, eliminating the need for complex role management systems.
+
+This approach aligns with REST architectural principles and capability-based security models, where possessing a URL grants specific, well-defined powers that can be delegated and constrained flexibly. The result is a simple yet powerful system where chat participation and management happen entirely through sharing and using capability URLs, making it easy to understand and use while maintaining fine-grained control over permissions.

 The actor management system raises some interesting questions too. Currently, when we start the server, it launches several actors with specific capabilities. We need to carefully consider whether to duplicate these across all instances or have certain specialized nodes. While redundancy is important - if one server goes down, you want others to pick up the slack - there might be cases where you want certain services to run on specific nodes only.
 
-For the clustering implementation, I'm considering using a [[Message Bus]] approach, possibly MQTT or NATS. Since we're working within a trusted cluster on an internal network, we can be a bit more relaxed about security (no need for certificates and TLS). One machine could run as a hub, or perhaps one per region, which might be simpler than managing peer-to-peer connections. This needs to tie into our handling of names, permanence, and [[Actor Identity]], possibly through a multiplexed actor system.

+## ugh field report
+
+I wonder what it is about the system that makes me so reluctant to do real time stuff you know with Web sockets and live updating HTML stuff it just feels like somehow horrible and I'm not exactly sure why.
+
+Some of it is just injury that it's hard to do anything so I'm reluctant to get into the weeds maybe I should have a little nap.

+## simple chat session
+
+So I started implementing some kind of simple chat session avoidance thingy and I'm wondering how to do it like OK I click chat and I get a thing with a text box but now I want to invite somebody like I wanna invite my brother to chat with me that means I want to be able to maybe like type his name into a form and then click create participant or invite participant or maybe there should not be ascend prompt and the chat itself that should be something you get when you join and you join as a user name you join as
