 # MokoSuite NPO
 Nonprofit management for MokoSuite. Layer 2 add-on (requires CRM).
 
+## [Unreleased]
+### Fixed
+- Installer no longer shows the "license / next-steps" success message when a bundled child extension failed to install. The package `postflight` now verifies every child declared in the manifest actually landed in `#__extensions` and shows an honest error instead. Fails open so a transient glitch never fakes a failure.
+
 ## Features
 - Donor management with giving levels
 - Donation tracking with fund allocation
