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
- Run the model and tools in a local sandbox.
- Restrict filesystem and network access to the task.
- Keep secrets out of the model context.
- 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 repository | What the module says it is |
|---|---|
cain/isolation/sandbox.py | Hardened Execution Isolation Fabric — Evolution 6: Project Sovereign Isolation. |
keystone/guard.py | Fix-safety checks: the fix may repair the defect, but it may not break the code around it. |
keystone/sandbox.py | Run a module's tests inside a bubblewrap sandbox: no network, read-only system, only its own files, time-boxed. |
cain/landlock_sandbox.py | Landlock 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.
