Score colour shows how many signals stand behind it, never how good it is: amber, three or more; dimmer amber, two; grey, one. The Evidence column names them.

Stars, forks and last commit are as GitHub reported them when Armory last read each repository: for most, 2 Sep 2026 or later. A repository may have changed since.
