Because the column is persisted before Ansible's no_log masking is applied,\na user with only read access to a workflow — or, via a regular-expression lookup that bypasses\nthe JSON cross-relation filter guard through the world-readable credential-types endpoint, any\nauthenticated user with no roles — can use the result count as a boolean/count oracle to recover,\ncharacter by character,
