# Software

Host tools and apps (diagnostics, configuration, test rigs), one folder per
tool, for example `software/diag/` with its own README and pyproject.toml or
Cargo.toml.

Versions: CalVer per tool, tagged `software/<tool>/YYYY.MM.MICRO` (for
example `software/diag/2026.10.0`: month without a leading zero, MICRO
counting that month's releases from 0). Each tool folder has its own
`CHANGELOG.md`, and its README says which firmware MAJOR versions it talks to.
