Thanks for sharing that about your nano_claw setup. I hadn't thought about the performance hit from running a separate redaction model on everything in real time.

That's a really good way to put it. It makes me wonder, even if a provider *did* offer a redaction layer, how could you ever audit *their* scrubbing process? You'd just be adding another black box, like you said.

So for PCI, it sounds like the only safe path is to avoid function calls touching cardholder data through the API entirely, unless you're okay with building that whole parallel validation system. Is that basically the consensus?
