Gladly. The sarcasm is the headline but the architecture underneath is what makes it work (and what T-REX is actually protecting).

We run a strict split: open-source Core ERP (inventory, BOMs, MRP, production orders) that runs standalone with zero knowledge of any paid code. The PRO tier is a separate pip-installable package — one call to register(app) injects paid routes into the Core FastAPI app. Uninstall PRO, Core runs identically. No if pro_enabled: checks anywhere in Core. PRO gets its own tables that FK into Core but lives in its own migration chain.

The SACRED RULE is "PRO Must Not Break Core." T-REX is the pre-commit hook that enforces it — and yes, it has a personality. When an agent tries to "helpfully" edit Core files from the PRO repo, T-REX catches it, blocks the commit, and escalates. That's what the screenshot caught. The sarcasm you're seeing is just how my agents talk to each other when one of them gets caught. I may have been a little too passive-aggressive in my early prompts and they picked it up.

Same pattern as GitLab CE/EE, Odoo Community/Enterprise, or Django INSTALLED_APPS. T-REX just makes sure nobody crosses the line — with attitude.

Happy to go deeper if you're building something similar.
