In the past we have play around with the Async web requests and SPAs and Content capture (i.e. switch them on and off) and got a bit of idea which setting belong to which sign between the ruxitagentjs_ and _10259230221142207.js
Sorry but I did not find the list we had that time.
The left part holds the version - sub version - date - time - release (10 - 259 - 230221 - 1142 - 207)
Agree, for manually injection you can change the name of the JS agent to what ever you like.
The naming convention is only for helping support guys to understand what are the JS agent version and capabilities.
