Two related fixes for the "switching agent mid-thread loses context"
issue:
1. LLM-context fix
The system prompt now includes a PRIOR HAND-OFF block whenever the
current conversation has been touched by more than one agent. It
lists the prior personas (name + role) and tells the new agent:
"Earlier turns were produced by other personas. Read them as
context, but answer in your own voice as the current persona."
Without this, switching from Atlas (Operator) to Pythia (Researcher)
left Pythia answering as if she'd produced Atlas's prior turns.
Tracked via two-trigger useEffect:
- On agent change with messages already in the thread, the prior
agent gets locked into history.
- On stream finish, the current active agent gets added (it just
produced a turn).
Cleared with the conversation.
2. UI-attribution fix
Each assistant turn now records which agent produced it
(messageAgents map: index -> Agent). The row signature in
MessageRow now reads that stamped agent rather than always echoing
the currently-active one. Switching agents mid-thread no longer
retroactively re-attributes prior responses.
Both maps are wiped by Clear conversation alongside the live snapshot
and initialLive ref, so a fresh thread starts truly fresh.

Arcadia Admin
Admin webapp for arcadia-core — the multi-tenant Phoenix backend. Built on the Crema design system with the Skyrise theme and started from the Vibespace starter.
Surfaces tenant management, user/role administration, billing, audit logs, storage configs, scheduled tasks, feature flags, and platform monitoring on top of arcadia's /api/v1 and /admin/* endpoints.
Quick start
npm install
npm run dev
Open http://localhost:5173. The app talks to arcadia at http://localhost:4000 by default; override with VITE_ARCADIA_URL in .env.local.
To use it for real:
- Have arcadia running locally (see
../reference/arcadia-app/DEV_SETUP.md). - Visit
/loginand sign in with admin credentials. In dev seeds:admin@example.com/AdminP@ssw0rd(tenantdefault).
Configuration
| Env var | Default | Purpose |
|---|---|---|
VITE_ARCADIA_URL |
http://localhost:4000 |
Base URL of arcadia-core. |
VITE_ARCADIA_TENANT |
default |
Tenant id sent as X-Tenant-ID. Override per-deployment. |
What's in here
App shell
app/components/layout/app-shell.tsx — left rail + appbar + avatar dropdown. Brand identity in app/lib/identity.ts (name: "Arcadia Admin", icon: Shield). The shell is template code, not a lib — fork it freely as admin features are added.
Arcadia client + auth UI
@crema/arcadia-client— typed HTTP client (generic + openapi-fetch-backedclient.typed), Phoenix Channels realtime, error normalization. Mounted at the root via<ArcadiaProvider>.@crema/arcadia-auth-ui— login / signup / password reset / 2FA forms, themed via Skyrise tokens. The/loginroute renders<LoginForm>.
Skyrise theme
lib-theme-skyrise — premium AI-first glass: iridescent body, frosted-glass surfaces, vivid text, Apple-spring motion. Default 18px root.
Surface tints (body[data-surface="snow|stone|sage|slate"]) and dark mode (html.dark) work out of the box via the existing pickers in the appbar.
Command bus
@crema/action-bus — every interactive element has data-action="<id>" so admin flows can be scripted, e2e-tested, or driven by an LLM through a single bus. See docs/AI_FIRST.md.

Conventions
- Brand strings, not literals. Use
useBrand().name— never hardcode "Arcadia Admin". [data-action="<id>"]on every interactive element. Naming:nav-*,appbar-*,tenants-*,users-*,audit-*, etc.- Tokens, not values.
bg-card,text-foreground,var(--primary)— never hex. - Lib edits commit to each lib's own repo.
git statushere only shows app-level changes.
