Traffic Light system for Programs - Proven - Unproven/Rev change - Quarantined

Hi Could a traffic light system be implemented to see what level a program is at. currently I would just do this through naming convention of the program but this could end up me having multiple programs that aren't necessary.

Green - Proven, Up-to current revision

Amber - Un-Proven / Revision Change needed

Red - Unproven Program / Quarantined
