Hey - I've found 1 issue, and left some high level feedback:

• The replace github.com/enbility/eebus-go => ../eebus-go entry in go.mod hardcodes a local path and will break consumers/CI that don’t have that directory layout; consider removing it or gating it behind a local-only config.
• The enbility dependencies are now pinned to pseudo-versions with future timestamps; double-check that these are intentional release candidates rather than local or temporary builds before merging.

**issue (bug_risk):** Local replace directive will break consumers who don’t have ../eebus-go.

This hardcodes your local directory structure into go.mod and will fail for others or in CI where `../eebus-go` isn’t present. If it’s only needed for local development, keep it out of the committed go.mod (e.g., via a local GOWORK/GOFLAGS setup or another local-only config).
