# Pull Request Template
## Description
Extends account-level feature flags by adding a second bigint bitset
column, `feature_flags_ext_2`, while preserving the existing
`flag_shih_tzu` feature check and enable/disable APIs. Existing flags
continue to live on `feature_flags`; future flags can opt into the
extension column through `config/features.yml` metadata.
