Dashboard from schema

A host needs to create events and see who’s coming. In Kumiko that UI is derived from the entity schema — screen definitions from chapter 6, rendered by the admin shell.

The host dashboard: the event list, rendered from the entity

Screens are data, not code

Section titled “Screens are data, not code”

An entityList or entityEdit screen is a plain object: which entity, which columns, which form layout. No component, no state, no fetch — the framework supplies all of it:

export const eventEditScreen: EntityEditScreenDefinition = {
  id: "event-edit",
  type: "entityEdit",
  entity: "event",
  layout: {
    sections: [
      { title: "showpony:section.event-basics", columns: 2,
        fields: [{ field: "title", span: 2 }, "slug", "startsAt", "location", "guestLimit"] },
      { title: "showpony:section.event-details", columns: 1, fields: ["description"] },
    ],
  },
};
— from src/features/show-pony/feature.ts
The auto-generated event form, with sections and typed fields
Editing an existing event — row click opens the same form, filled

The guest list is the same mechanism on rsvp:

The guest list, the anonymous RSVPs collected per host

Two accounts, two stories

Section titled “Two accounts, two stories”

Show Pony seeds two logins on the apex — on purpose they are not the same kind of user:

AccountWhoTenant membershipWorkspace
[email protected]Mira (demo host)demo — Admin + TenantAdminEvents only
[email protected]Platform operator_platform — User (login anchor only)Platform only

Why not put sysadmin on the demo tenant?

Section titled “Why not put sysadmin on the demo tenant?”

Early demos gave the operator a membership on demo so login had a tenant context. That leaked into the product UX:

  • Sysadmin appeared on Mira’s Team screen as a tenant admin.
  • The Events workspace showed up (because access.admin includes SystemAdmin).
  • Operators thought they were “also a host” instead of running the platform.

Fix (publicstatus pattern):

  1. Internal tenant _platform — membership anchor for login, not a customer subdomain.
  2. Global role SystemAdmin — tenants, users, audit, jobs.
  3. Host workspace uses tenant roles only (TenantAdmin, Admin) — not the global access.admin preset that includes SystemAdmin.
const HOST_WORKSPACE_ROLES = access.roles("TenantAdmin", "Admin");


r.workspace({
  id: "host",
  access: { roles: HOST_WORKSPACE_ROLES },
  // ...
});
r.workspace({
  id: "platform",
  access: { roles: access.systemAdmin },
  // ...
});
— from src/features/app-shell/feature.ts

Sysadmin seed (dev + prod):

await seedAdmin(db, {
  email: "[email protected]",
  globalRoles: ["SystemAdmin"],
  memberships: [{
    tenantId: PLATFORM_TENANT.id,
    tenantKey: "_platform",
    roles: ["User"],
  }],
});
— from bin/server.ts · bin/demo-tenants.ts

Fresh installs get this from boot seed (bin/server.ts / bin/main.ts + bin/demo-tenants.ts). No extra migration files needed for new clones.

Platform operator overview after logging in as sysadmin

Log in as sysadmin → you land in Platform (tenants, users, audit). Log in as Mira → Events only. Same apex URL, different story.

Guest PII on the list is covered in chapter 14.

Text, separate from the schema

Section titled “Text, separate from the schema”

Labels come from chapter 2 (src/features/show-pony/i18n/keys.ts). Here you only define which columns and sections appear — the framework resolves the strings.

Browser entry

Section titled “Browser entry”

createKumikoApp with the shell and client features — three lines:

createKumikoApp({
  shell: AppShell,
  clientFeatures: [emailPasswordClient(), showPonyClient],
});
— from src/client-admin.tsx

emailPasswordClient() adds the login gate and session on top of the admin bundle.
