Typed client + types for the arcadia integration registry (on arcadia-llm-gateway).
One createIntegrationsApi(client, mode) factory serves both surfaces:
- operator → /api/v1/integrations* (any scope, scope filters)
- tenant → /api/v1/me/integrations* (scope forced server-side)
Plus shared types (Integration/Credential/UsageEntry/*Input/TestVerdict) and
display helpers (formatUsd, credentialHealth). Consumed by arcadia-admin and
arcadia-console as a sibling lib via vite/tsconfig aliases (no build step).
Secrets are write-only; the rich panels stay per-app.
