+# MS22 Phase 1: DB-Centric Multi-User Agent Architecture
+
+## Design Principles
+
+1. **2 env vars to bootstrap** — `DATABASE_URL` + `MOSAIC_SECRET_KEY`
+2. **DB-centric config** — All runtime config in Postgres, managed via WebUI
+3. **Mosaic is the gatekeeper** — Users authenticate to Mosaic, never to OpenClaw directly
+4. **Per-user agent isolation** — Each user gets their own OpenClaw container(s) with their own credentials
+5. **Onboarding-first** — Breakglass user + wizard on first boot
+6. **Generic product** — No hardcoded names, models, providers, or endpoints
+
+## Architecture Overview

+
+## Container Lifecycle
+
+### User containers (on-demand)
+
+1. User logs in → Mosaic checks `UserContainer` table
+2. No running container → Mosaic calls Docker API to create one
+3. Injects user's encrypted API keys via config endpoint
+4. Routes chat requests to user's container
+5. Idle timeout (configurable, default 30min) → scale to zero
+6. State volume persists (sessions, memory, auth tokens)
+7. Next request → container restarts, picks up state from volume
+
+### System containers (always-on, optional)
+
+- Admin-provisioned for system tasks (monitoring, scheduled jobs)
+- Use admin-configured shared API keys
+- Not tied to any user
+
+## Auth Layers
+
+| Flow                            | Method                                                                 |
+| ------------------------------- | ---------------------------------------------------------------------- |
+| User → Mosaic WebUI             | Breakglass (local) or OIDC (configured in settings)                    |
+| Mosaic API → OpenClaw container | Bearer token (auto-generated per container, stored encrypted in DB)    |
+| OpenClaw → LLM providers        | User's own API keys (delivered via config endpoint, decrypted from DB) |
+| Admin → System settings         | RBAC (admin role required)                                             |
+| Internal config endpoint        | Bearer token (container authenticates to fetch its config)             |
+
+## Database Schema
+
+### System Tables

+
+```prisma

+  id              String    @id @default(cuid())
+  userId          String    @unique
+  containerId     String?   // Docker container ID (null = not running)

+
+```prisma

+  id             String  @id @default(cuid())
+  userId         String  @unique
+  primaryModel   String?           // user's preferred model
+  fallbackModels Json    @default("[]")
+  personality    String?           // custom SOUL.md content
+  providerId     String?           // default provider for this user
+  createdAt      DateTime @default(now())
+  updatedAt      DateTime @updatedAt
+}
+```
+
+## Internal Config Endpoint
+
+`GET /api/internal/agent-config/:containerType/:id`
+
+- Auth: Bearer token (container's own gateway token)
+- Returns: Complete `openclaw.json` generated from DB
+- For user containers: includes user's providers, model prefs, personality
+- For system containers: includes admin provider config
+
+Response assembles openclaw.json dynamically:
+
+```json
+{
+  "gateway": { "mode": "local", "port": 18789, "bind": "lan", "auth": { "mode": "token" } ... },
+  "agents": { "defaults": { "model": { "primary": "<from UserAgentConfig>" } } },
+  "models": { "providers": { "<from LlmProvider rows>": { ... } } }
+}
+```
+
+## Container Lifecycle Manager
+
+NestJS service that manages Docker containers:
+
+```typescript
+class ContainerLifecycleService {
+  // Create and start a user's OpenClaw container
+  async ensureRunning(userId: string): Promise<{ url: string; token: string }>;
+
+  // Stop idle containers (called by cron/scheduler)
+  async reapIdle(): Promise<number>;
+
+  // Stop a specific user's container
+  async stop(userId: string): Promise<void>;
+
+  // Health check all running containers
+  async healthCheckAll(): Promise<HealthStatus[]>;
+
+  // Restart container with updated config
+  async restart(userId: string): Promise<void>;
+}
+```
+
+Uses Docker Engine API (`/var/run/docker.sock` or TCP) via `dockerode` npm package.
+
+## Onboarding Wizard
+
+### First-Boot Detection
+
+- API checks: `SystemConfig.get("onboarding.completed")` → null = first boot
+- WebUI redirects to `/onboarding` if not completed
+
+### Steps
+
+**Step 1: Create Breakglass Admin**
+
+- Username + password → bcrypt → `BreakglassUser` table
+- This user always works, even if OIDC is misconfigured
+
+**Step 2: Configure Authentication (optional)**
+
+- OIDC: provider URL, client ID, client secret → encrypted in `SystemConfig`
+- Skip = breakglass-only auth (can add OIDC later in settings)
+
+**Step 3: Add Your First LLM Provider**
+
+- Pick type → enter API key/endpoint → test connection → save to `LlmProvider`
+- This becomes the admin's default provider
+
+**Step 4: System Agents (optional)**
+
+- Configure always-on system agents for monitoring/ops
+- Or skip — users can just use their own personal agents
+
+**Step 5: Complete**
+
+- Sets `SystemConfig("onboarding.completed") = true`
+- Redirects to dashboard
+
+### Post-Onboarding: User Self-Service
+
+- Each user adds their own LLM providers in profile settings
+- Each user configures their preferred model, personality
+- First chat request triggers container creation
+
+## Docker Compose (final)
+
+```yaml
+services:
+  mosaic-api:
+    image: mosaic/api:latest
+    environment:
+      DATABASE_URL: ${DATABASE_URL}
+      MOSAIC_SECRET_KEY: ${MOSAIC_SECRET_KEY}
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock # Docker API access
+    networks:
+      - internal
+
+  mosaic-web:
+    image: mosaic/web:latest
+    environment:

+    networks:
+      - internal
+
+  # System agent (optional, admin-provisioned)
+  # mosaic-system:
+  #   image: alpine/openclaw:latest
+  #   ... (managed by ContainerLifecycleService)
+
+  # User containers are NOT in this file —
+  # they are dynamically created by ContainerLifecycleService
+  # via the Docker API at runtime.
+
+networks:
+  internal:
+    driver: overlay
+
+volumes:
+  postgres-data:
+```
+
+Note: User OpenClaw containers are **not** defined in docker-compose. They are
+created dynamically by the `ContainerLifecycleService` when users start chatting.
+
+## Entrypoint (for dynamically created containers)
+
+```sh
+#!/bin/sh
+set -e
+: "${MOSAIC_API_URL:?required}"
+: "${AGENT_TOKEN:?required}"
+: "${AGENT_ID:?required}"
+
+# Fetch config from Mosaic API
+curl -sf "${MOSAIC_API_URL}/api/internal/agent-config/${AGENT_ID}" \
+  -H "Authorization: Bearer ${AGENT_TOKEN}" \
+  -o /tmp/openclaw.json
+
+export OPENCLAW_CONFIG_PATH=/tmp/openclaw.json
+exec openclaw gateway run --bind lan --auth token
+```
+
+Container env vars (injected by ContainerLifecycleService):
+
+- `MOSAIC_API_URL` — internal API URL
+- `AGENT_TOKEN` — this container's bearer token (from DB)
+- `AGENT_ID` — container ID for config lookup
+
+## Config Update Strategy
+
+When a user changes settings (model, provider, personality):
+
+1. Mosaic API updates DB
+2. API calls `ContainerLifecycleService.restart(userId)`
+3. Container restarts, fetches fresh config from API
+4. OpenClaw gateway starts with new config
+5. State volume preserves sessions/memory across restarts

+## Open Questions (Resolved)
+
+1. ~~Config updates → restart?~~ **Yes.** Mosaic restarts the container, fresh config on boot.
+2. ~~CLI alternative for breakglass?~~ **Yes.** Both WebUI wizard and CLI (`mosaic admin create-breakglass`).
+3. ~~Config cache TTL?~~ **Yes.** Config fetched once at startup, changes trigger restart.
+
+## Security Isolation Model
+
+### Core Principle: ZERO cross-user access
+
+Every user is fully sandboxed. No exceptions.
+
+### Container Isolation
+
+- Each user gets their **own** OpenClaw container (separate process, PID namespace)
+- Each container has its **own** Docker volume (sessions, memory, workspace)
+- Containers run on an **internal-only** Docker network — no external exposure
+- Users NEVER talk to OpenClaw directly — Mosaic proxies all requests
+- Container gateway tokens are unique per-user and single-purpose
+
+### Data Isolation (enforced at API + DB level)
+
+| Data             | Isolation                 | Enforcement                                                                       |
+| ---------------- | ------------------------- | --------------------------------------------------------------------------------- |
+| LLM API keys     | Per-user, encrypted       | `LlmProvider.userId` — all queries scoped by authenticated user                   |
+| Chat history     | Per-user container volume | Separate Docker volume per user, not shared                                       |
+| Agent memory     | Per-user container volume | Separate Docker volume per user                                                   |
+| Agent config     | Per-user                  | `UserAgentConfig.userId` — scoped queries                                         |
+| Container access | Per-user                  | `UserContainer.userId` — Mosaic validates user owns the container before proxying |
+
+### API Enforcement
+
+- **All user-facing endpoints** include `WHERE userId = authenticatedUser.id`
+- **No admin endpoint** exposes another user's API keys (even to admins)
+- **Chat proxy** validates: authenticated user → owns target container → forwards request
+- **Config endpoint** validates: container token matches the container requesting config
+- **Provider CRUD** is fully user-scoped — User A cannot list, read, or modify User B's providers
+
+### What admins CAN see
+
+- Container status (running/stopped) — not contents
+- User list and roles
+- System-level config (OIDC, system agents)
+- Aggregate usage metrics (not individual conversations)
+
+### What admins CANNOT see
+
+- Other users' API keys (encrypted, no decrypt endpoint)
+- Other users' chat history (in container volumes, not in Mosaic DB)
+- Other users' agent memory/workspace contents
+
+### Future: Team Workspaces (NOT in scope)
+
+Team/shared workspaces are a potential future feature where users opt-in to
+shared agent contexts. This requires explicit consent, shared-key management,
+and a different isolation model. **Not designed here. Not built now.**
+
+### Attack Surface Notes
+
+- Docker socket access (`/var/run/docker.sock`) is required by Mosaic API for container management. This is a privileged operation — the Mosaic API container must be trusted.
+- `MOSAIC_SECRET_KEY` is the root of trust for encryption. Rotation requires re-encrypting all secrets in DB.
+- Container-to-container communication is blocked by default (no shared network between user containers unless explicitly configured).
