The 2026 development

Microsoft presented a coding model intended to run directly on PCs.

The governance gap

Local execution reduces data exposure but not action risk. A local agent still writes files, runs builds and can reach the network, and the user may have less monitoring than a server deployment.

Where CAIN-42 fits: Moat 6 — Adversarial Trust Engine

Core question: Can CAIN break its own guarantees? Continuous attack, mutation and red-team testing of the controls themselves.

Apply the same guard locally: a scoped sandbox, an allowlist of tools, no inherited secrets, and a signed local record. Local is a deployment mode, not a trust exemption.

How the wiring works

  1. Run the model and tools in a local sandbox.
  2. Restrict filesystem and network access to the task.
  3. Keep secrets out of the model context.
  4. Write a local signed record of the run.

What is real today

LIBRARY Production code and tests exist in this repository; there is no hosted route for this exact use.

The sandbox and guard are real on this host. No Microsoft model or PC hardware is involved.

Component in this repositoryWhat the module says it is
cain/isolation/sandbox.pyHardened Execution Isolation Fabric — Evolution 6: Project Sovereign Isolation.
keystone/guard.pyFix-safety checks: the fix may repair the defect, but it may not break the code around it.
keystone/sandbox.pyRun a module's tests inside a bubblewrap sandbox: no network, read-only system, only its own files, time-boxed.
cain/landlock_sandbox.pyLandlock filesystem (and optional TCP) restriction for processes CAIN launches -- Sovereign Evolution 3.

Descriptions are the first line of each module's own docstring, read without importing it. A module path is a pointer into this repository, not a hosted endpoint. Its existence is checked by the test suite; its status for this use is the label above.
