# Activate a model checkpoint

> Requires `onboarding_admin` + CSRF. Returns 404 if the given checkpoint version does not exist. Marks that checkpoint version active (deactivating all others); if the tenant has an existing dataset, enqueues a `materialize_insights` job for its latest version (idempotency key `materialize-activation:{tenant_id}:{dataset_id}:{checkpoint_version}`) so the console has fresh collections to show and sets `client_visible` on the matching `insight_collections` rows. Also sets `share_onboarding_outputs` on the tenant's `control.tenants` row, flips tenant lifecycle state to `review`, and writes a `control.audit_log` row (`checkpoint_activated`).

  title: CL MVP Product API
  description: >-
    The Causeloop MVP Product API is a deliberately small, explicitly
    allowlisted HTTP surface: `services/api/product_app.py` enumerates every one
    of the 44 published (method, path) operations drawn from seven routers, and
    only those operations are mounted onto this app -- everything else defined
    in the underlying routers (and the entire legacy research surface in
    `services/api/main.py`) is not exposed here. Staff (employee) and
    tenant-user sessions are separate cookie-based principals with no shared
    session table; mutating requests are protected by a double-submit CSRF
    cookie/header pair. See `/api-reference/authentication` for session and CSRF
    details, and `/api-reference/errors-and-conventions` for shared error shapes
    and status-code conventions.
