 - Multi-tenancy: each server instance serves one tenant (configured via `CAMELEER_TENANT_ID`, default: `"default"`). Environments (dev/staging/prod) are first-class — agents send `environmentId` at registration and in heartbeats. JWT carries `env` claim for environment persistence across token refresh. PostgreSQL isolated via schema-per-tenant (`?currentSchema=tenant_{id}`). ClickHouse shared DB with `tenant_id` + `environment` columns, partitioned by `(tenant_id, toYYYYMM(timestamp))`.
 - Storage: PostgreSQL for RBAC, config, and audit; ClickHouse for all observability data (executions, search, logs, metrics, stats, diagrams). ClickHouse schema migrations in `clickhouse/*.sql`, run idempotently on startup by `ClickHouseSchemaInitializer`. Use `IF NOT EXISTS` for CREATE and ADD PROJECTION.
 - Logging: ClickHouse JDBC set to INFO (`com.clickhouse`), HTTP client to WARN (`org.apache.hc.client5`) in application.yml
-- Security: JWT auth with RBAC (AGENT/VIEWER/OPERATOR/ADMIN roles), Ed25519 config signing (key derived deterministically from JWT secret via HMAC-SHA256), bootstrap token for registration. CORS: `CAMELEER_CORS_ALLOWED_ORIGINS` (comma-separated) overrides `CAMELEER_UI_ORIGIN` for multi-origin setups (e.g., reverse proxy). UI role gating: Admin sidebar/routes hidden for non-ADMIN; diagram toolbar and route control hidden for VIEWER; App Config is a per-app main tab (read-only for VIEWER, editable for OPERATOR+). Role helpers: `useIsAdmin()`, `useCanControl()` in `auth-store.ts`. Route guard: `RequireAdmin` in `auth/RequireAdmin.tsx`.

 - OIDC: Optional external identity provider support (token exchange pattern). Configured via admin API/UI, stored in database (`server_config` table). Configurable `userIdClaim` (default `sub`) determines which id_token claim is used as the user identifier. Resource server mode: accepts external access tokens (Logto M2M) via JWKS validation when `CAMELEER_OIDC_ISSUER_URI` is set. `CAMELEER_OIDC_JWK_SET_URI` overrides JWKS discovery for container networking. `CAMELEER_OIDC_TLS_SKIP_VERIFY=true` disables TLS cert verification for OIDC calls (self-signed CAs). Scope-based role mapping (case-insensitive): `admin`/`server:admin` → ADMIN, `operator`/`server:operator` → OPERATOR, `viewer`/`server:viewer` → VIEWER. SSO: when OIDC enabled, UI auto-redirects to provider with `prompt=none` for silent sign-in; falls back to `/login?local` on `login_required`, retries without `prompt=none` on `consent_required`. Auto-signup provisions new OIDC users with default roles. System roles synced on every OIDC login (revocations propagate on next login); group memberships are never touched. Supports ES384, ES256, RS256.
 - User persistence: PostgreSQL `users` table, admin CRUD at `/api/v1/admin/users`
 - Usage analytics: ClickHouse `usage_events` table tracks authenticated UI requests, flushed every 5s
