🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR adds a new FedRamp boolean feature flag (fedramp-gov-region, default false) that is currently a no-op. The change follows the established FlagKey pattern precisely: the flag is registered in activePasswordManagerFlags, wired into both when branches in FeatureFlagListItems.kt (preserving exhaustiveness), given a non-localized debug-menu string, and covered by updates to both existing tests. No security, correctness, or breaking-change concerns identified.

Code Review Details

No blocking findings.

Minor (non-blocking): the KDoc for FedRamp reads "theFedRAMP feature" (missing space) in core/src/main/kotlin/com/bitwarden/core/data/manager/model/FlagKey.kt:175. Cosmetic only.
