Month 2025-10: Delivered IPP flow corrections and configuration consolidation for 18F/identity-idp to improve reliability and onboarding experience. Implemented gating fix to prevent navigation to the Choose ID Type step after IPP initiation and consolidated IPP-related environment variables for consistent enabling across environments. Added tests validating IPP eligibility/opt-in behavior and updated tests/views to reflect the consolidated config. These changes reduce user friction, lower risk of misconfiguration, and strengthen IPP-related compliance checks.
