Build failure during the 2026-07-07 “build all packages for x86_64”
private-repo release pass. Same systemic intra-tree dependency gap as
memory/kdstatemachineeditor.md / memory/TOOLING_NOTES.md: depends on
kmime5 (another custom package in this tree) – error: target not
found: kmime5. Not a package-specific defect; not fixed as part of this
pass.
