New project: OOXML Behavioral Intelligence — behavioral spec research

Hi Open XML SDK team,

I am launching an open research initiative to document real-world OOXML behavior — the gap between the ECMA/ISO specification and what Office actually does. The project covers differential testing, compatibility case databases, and future AI-assisted discovery.

As the technical authority on OOXML, your guidance would be invaluable — even just pointing us at known edge cases or undocumented behaviors worth documenting.

Open to feedback or a brief discussion.

Start by reviewing the linked ooxml-behavioral-intelligence repository and the issue's request for guidance on real-world OOXML behavior. The issue does not name files, tests, or an entry point in Open-XML-SDK; completion would require an agreed scope and a documented response or set of relevant edge cases.
