Basically. There are miscellaneous uses, like IdP expressions that use `runScript()`, and I use it in my EtherNet/IP driver for communication event handling.

Any scripting where the origin call is inside a project strictly uses that project's inheritance chain for its library scripts. Arrange for "SA" to also inherit from "P". 🤷‍♂️

For more complex situations, consider something like this:

> Put all of the logic in project library scripts, in the "universe" project at the root of your hierarchy, if you must. Then, in leaf projects, use one-line calls to the appropriate logic from event scripts and message handlers. (I don't agree with your desire, but this is what you must do to achieve it.) I recommend you not put all your scripts (eggs) in one inheritable project (basket). I recommend a hierarchy something like this: universe ├bg\_common │├gsp │├background1 │├background2 │└we…

For compatibility with v7.9 upgrades, the gateway scripting project is the only project that can be both inheritable and have runnable library functions. (Though it otherwise doesn't run.)
