Hi everyone. I’ve been lurking for a while, soaking up the collective knowledge here, and I want to start by saying how much I appreciate this community. I’ve built a small homelab to practice security concepts, mostly around segmenting my self-hosted services and playing with firewall rules, but the enclave talk here has really pulled me into a deeper rabbit hole.

I’m trying to map the high-level assurances from NEAR AI's documentation to what’s actually happening under the hood, specifically for side-channels. We all know the big names—cache timing, Spectre/Meltdown variants, branch history—but the practical, deployed difference between IronClaw and NemoClaw on this front feels… fuzzy. Marketing says both are "hardened," but as someone who just spent a week reworking my container network policies after a scare, I believe the devil is in the default configuration and the actual isolation guarantees.

From what I’ve pieced together (and please, correct me if I’m wrong):
* **IronClaw** seems to rely heavily on the host kernel and a more traditional hypervisor model. Its mitigations are often about configuring the underlying systems (like disabling hyperthreading, careful core pinning). This feels like it puts a lot of trust in the host’s security posture and the admin’s diligence.
* **NemoClaw**, with its microkernel and formal verification claims, appears to be designed from the silicon up to limit shared resources. The literature suggests things like deterministic cache flushing and stronger memory isolation are architectural, not just configured.

My paranoid brain has questions:
* In a practical deployment, does IronClaw’s reliance on, say, Intel’s SGX or AMD’s SEV, mean we’re inherently tied to those platforms' historical (and ongoing) side-channel vulnerabilities? Are the mitigations reactive patches to the hardware, or is there a proactive design?
* For NemoClaw, how much of the "hardening" is in the reference architecture vs. what a typical user (or an AI agent host) actually deploys? If I’m self-hosting something, am I likely to weaken the model by allowing certain shared services?
* Has anyone performed, or seen, any practical exposure assessments? Not theoretical CVEs, but actual "here’s the attack surface if you have two untrusted workloads on the same physical host" comparisons.

I’m leaning towards the idea that NemoClaw’s architecture is fundamentally more resistant by design, but I worry I’m falling for the "newer is better" trap. I’d love to hear from those with deeper hands-on experience, especially if you’ve stress-tested these setups in a lab environment. What configurations made the biggest difference in your threat model?
