This section details on the original issue you should resolve

<issue_title>Events Page</issue_title>
<issue_description>So that people can view details of a specific Event
I want an Event web page
Unlike today where events only appear on an InterestGroup web page

Requirements:

• A new URL is available at /interest-group-short-name/event-short-name
• The web page uses the same or very similar styling as the /interest-group-short-name url. This includes the link to the interest group calendar and image for the event
• The event web page shows event's title, start and end times, location, and event notes</issue_description>

@copilot examine main and use its implementation of Event notes

@copilot examine main and use its implementation of Event notes

Done in dbd148c. Split the combined UpdateEventAddShortAndNotes migration into two separate migrations matching main's pattern:

• AddNotesToEvent — identical to main's implementation (just the notes field)
• AddShortToEvent — new migration for the URL slug field needed by this PR

Just putting it on record here. This is garbage. Copilot doesn’t understand Vapor routes so it didn’t include them. It literally tried to cast a string like "hangin-at-andytown" to a UUID init. I asked it to create an event page but it didn’t think to ask or clarify if the event page should be linked to from anywhere. (I admit I messed up the requirement spec, but COME ON.)

Anyway. I don’t have any faith in this PR. Debating on closing it as unacceptable but first I have to waste time seeing if there’s anything salvageable from this.

It doesn’t understand Fluent, either. So, it can’t handle relations properly.

I’m not mad. I’m just disappointed. This is why people hate Microslop.

And, yeah, Claude’s models are also to blame.
