When to run it

• After luban setup, before doing anything else
• When a new tool you expect to be there (e.g., clang-tidy) fails to launch
• When migrating to a new machine — confirms your <data>/<cache>/<state>/<config> resolution is sane

Reading the output

• ✓ green check + path = installed and resolvable
• · grey dot + (not found) = not installed, or installed but not on this shell's PATH
• ✗ red cross = something's actively wrong (e.g., installed.json is corrupt)

If a tool shows (not found) but installed.json lists it: open a fresh shell after luban env --user, or call <data>\env\activate.cmd.
