# Completed Steps
- 2026-09-21: rewrote `script/test` to the canonical pattern (30s timeout,
`-race -cover`, quiet-first with verbose-on-failure rerun) and fixed the
process-global logger data race it surfaced (#67)
- 2026-09-21: added the canonical `.editorconfig`, made `.gitignore` cover
secrets, OS, editor, and Go artifacts, and removed the dead Drone CI
references from `.gitignore` and `bin/gitrev.sh` (#72)
