collection member policy is not set for collection '%s'

Error message

collection member policy is not set for collection '%s'

What it means

Returned by validateCollectionConfigMemberOrgsPolicy when a static collection defines no member-org policy. Every private collection must declare which orgs can access the data; the nil check fires before signature-policy validation can run.
