+- `LOG_LEVEL=BASIC` (and the `BASIC`-gated output under `DEBUG`) emitted nothing. `main` set the local `flagLog` from `LOG_LEVEL` but only ever assigned `log.Debug`, never `log.Basic`, so the package-level `Basic` flag stayed `false` and every `log.Basicf(...)` call was silently swallowed. `log.Basic` is now set from `flagLog`, restoring the progress/affected-package logging on stderr while the JSON result stays on stdout.
