Hey all. I've been running a nano-claw agent on my home server for a few weeks now, and I keep seeing references to Spectre and side channels in the docs. It feels like a black box, so I tried to get a practical grip on it.

I built a simple comparison of three enclave runtimes (SGX, SEV, and Keystone) against Spectre v1 and v2. I'm not a hardware expert, so I focused on what the runtimes *claim* to mitigate and what's left to the software (like my agent). My findings:

* SGX seems to have the strongest hardware-level claims for cache timing isolation.
* SEV's mitigation leans heavily on the hypervisor and kernel patches.
* Keystone, being newer, has interesting software-defined approaches but feels more DIY.

My main question: for those running in production, how much do you actually worry about this layer? Are the default IronClaw agent builds considered safe "out of the box" against these CPU-level attacks, or is there extra hardening we should do? The docs mention "NEAR AI's current mitigations" but I'd love a plain-English summary. 😅

I can share my test setup if anyone's interested—it's just some basic Python scripts using the `perf` events, nothing fancy.
