build.js was an esbuild-based build script from the pre-Vite era (March 2026).
It is not referenced by package.json, CI, or any config. Vite is used for
both sync and rmo builds. Also dropped pkgs.esbuild from flake.nix devShell.
TomTom was added Feb 2026 for routing but was never imported outside
its own directory. Stadia Maps is now the geocoding and tile provider.
No references in go.mod, go.sum, or any Go file.
"I'd like you to take a look at the project nidus-sync. It has been developed over the past 6 months and had several different architectural approaches that have evolved over time. The git history may be especially useful to see the
evolution. Write up a report of what you understand has happend, with approximate timelines. This should go in HISTORY.md. Determine which changes are incomplete - libraries or approaches that are no longer preferred, but not fully
removed yet. Create another file, CLEANUP.md, which lists out cleanup
efforts that should be done to completely remove these older,
less-preferred parts of the code."
