A practical walkthrough of merging multiple GitHub repositories into a single new one while preserving full git history, tags, and releases. The author uses `git subtree` to bring both repos' commit histories into a unified repo under separate package directories, then writes a Bash script using the GitHub CLI to migrate all releases with namespaced tags. A notable gotcha: `git subtree add` fails with an opaque 'ambiguous HEAD' error on repos with no initial commit, solved by creating an empty commit first.
