# Software

Archive vendor or third-party software related to supported USB meter models here.

Recommended contents:

- Android applications
- PC software packages
- extracted binaries or installers when legally safe to preserve
- companion notes about supported models, versions, and observed protocol hints

Current status:

- Android applications imported from the `UM24` archive
- Android application imported from the `TC66` archive
- PC software archives inspected locally but intentionally excluded from the repository because they are bulky and unlikely to be used by the current app
- font file from the archive intentionally not imported for now because it does not appear device-specific

Working note:

- some imported software artifacts appear branded at the RuiDeng family level rather than clearly tied to a single model
- until deeper reverse engineering confirms scope, treat them as potentially relevant to `UM24C`, `UM25C`, and `UM34C`
- the `TC66` archive also contains TC66-specific software artifacts that should be treated as a separate line unless overlap is later confirmed

Retention note:

- prefer keeping software artifacts that are small enough to clone comfortably and directly useful for protocol or workflow analysis
- keep metadata notes for larger archives even when the archive itself stays out of git
- for now, that means Android artifacts stay in-repo, while PC software stays documented but untracked
