Successful Response
Bad request — malformed input or failed validation.
Resource not found, or hidden for tenant-enumeration safety (the caller lacks permission to know whether the resource exists).
Conflict — the current resource state does not allow this operation (e.g. assessment already started, email already in use).
Semantic validation failure — request shape was valid but contents were not.
Too many requests — rate limited. Retry after the window resets.
Internal server error — unexpected failure.
