Isolation is a business risk language.

Local and cloud parity is not automatic safety.

Too many substrates become an integration tax.

My rule: Fund the boundary equally.

Full written post / accessibility read

Leaders do not need to recite seccomp flags. They do need to know whether an agent shares a host kernel with other workloads or sits in a microVM with its own kernel. That changes blast radius language in an incident.

Local and cloud parity on microVM isolation is a strong product story. It still needs the same substrate review: secrets, network, files, metering, and what residuals you accept.

Every experiment that picks a different sandbox partner adds glue. Useful options can become operational debt. Prefer a short approved substrate list.

If model spend has a line item, substrate review should too. My rule is to security review the substrate equal to model choice and harness choice.

Four-beat scene transcript

1. Isolation is a business risk language.

Leaders do not need to recite seccomp flags. They do need to know whether an agent shares a host kernel with other workloads or sits in a microVM with its own kernel. That changes blast radius language in an incident.

Visual: Shared kernel versus own kernel changes incident blast radius.

2. Parity pitches still need review.

Local and cloud parity on microVM isolation is a strong product story. It still needs the same substrate review: secrets, network, files, metering, and what residuals you accept.

Visual: Local and cloud parity is not automatic safety.

3. Partner menus are portfolios.

Every experiment that picks a different sandbox partner adds glue. Useful options can become operational debt. Prefer a short approved substrate list.

Visual: Too many substrates become an integration tax.

4. Fund the boundary equally.

If model spend has a line item, substrate review should too. My rule is to security review the substrate equal to model choice and harness choice.

Visual: Substrate review beside model spend.
