I need scripts to run on github webhooks just as bad as you do. But this one-size-fits-all "lets make scripts but in yaml" shit has got to go.

Yaml acts as the "purely ci details". Script logic goes in... SCRIPTS!

Every CI/CD engine has a million different 'input' layers - environment variables, repo variables, workflows from various branches, maybe the git commit object. Oftentimes your scripts will have the ability to jam more variables into the 'input' layer for later scripts - such as in the case of the github environment variables. UNFORTUNATELY, it's never clear WHICH input layers are available to WHICH parts of the script. "Oh, no, you can't use outputs from this script to as arguments for something in our yaml, because the yaml is calculated first." Well thanks, Mr Nadella, I'll just torch my entire pipeline and start over.

My form of dynamic ci materializes all variables into logged and exam-able ci code. Hidden ci assembly magic was one of the first things I got rid of because life triggered
