The package postflight showed the "License Key Required" / next-steps
message even when a bundled child extension failed to sub-install
(Joomla only logs those failures). Add a fail-open manifest verifier
(missingChildExtensions) that confirms every declared child landed in
#__extensions and enqueues an error + returns before the license path
when any are missing. Fails open so a transient glitch never fakes a
failure.
