GROUNDING.MD - grounding during software development enforcing agents to follow community-supported domain knowledge

What variant of Codex are you using?

CLI

What feature would you like to see?

We are suggesting Codex "knows" what a GROUNDING.md file is and gives it context priority over AGENTS.md, SKILLS.md, etc. natively. We have demonstrated in other agent scaffolds that system prompt can do this (most of the time), but we would love to get it baked in. There is a preprint "letter" describing it, https://arxiv.org/abs/2604.21744 , but the GROUNDING.md provides an invariant enforcement layer using community-supported domain knowledge, giving users confidence their software isn't breaking any rules (Hard Constraints). When they do attempt to break a HC, the agent stops the user and tells them why not. We see more of these GROUNDING.md files being generated, beyond our proof of principle with proteomics.
