tibet-cortex 0.2.0

TIBET Cortex — Zero-trust AI knowledge processing. JIS-gated, Airlock-protected, TIBET-audited.

TIBET Cortex (Python)

Zero-trust AI knowledge processing. Data that protects itself.

Python client for the TIBET Cortex framework. For production use with memory-level security guarantees (mlock, zeroize), use the Rust crates.

Install

pip install tibet-cortex

Quick Start

JIS — Multi-Dimensional Access Control

from cortex import JisClaim, JisPolicy, JisGate

# Partner in strategy, EU, clearance 3
claim = JisClaim(
    actor="[e-mail]",
    clearance=3,
    role="partner",
    department="strategy",
    geo=["NL", "DE"],
)

# M&A document policy
policy = JisPolicy(
    min_clearance=3,
    allowed_roles=["partner"],
    allowed_departments=["strategy"],
    allowed_geos=["NL", "DE", "FR"],
)

verdict = JisGate.evaluate(claim, policy)
print(f"Access: {verdict.allowed}")  # True

# Intern tries same document
intern = JisClaim(actor="[e-mail]", clearance=1, role="intern")
verdict = JisGate.evaluate(intern, policy)
print(f"Access: {verdict.allowed}")  # False
print(f"Reasons: {[d.reason.value for d in verdict.denials]}")
# ['clearance_too_low', 'role_not_allowed', 'department_not_allowed', 'geo_restricted']

Envelope — JIS-Gated Data

from cortex import Envelope, EnvelopeBlock

env = Envelope(id="doc_001")
env.add_block(EnvelopeBlock.new_embedding(b"vector data"))
env.add_block(EnvelopeBlock.new_content(b"M&A strategy for client X", jis_level=3))

# Everyone can search (embedding is JIS 0)
assert env.embedding() is not None

# Only clearance 3+ can read content
assert env.content(accessor_jis_level=1) is None
assert env.content(accessor_jis_level=3) is not None

Airlock — Controlled Processing

from cortex import Airlock

airlock = Airlock()

result, session = airlock.process(
    data=b"sensitive document",
    actor="[e-mail]",
    jis_level=2,
    callback=lambda plaintext: len(plaintext),
)

print(f"Result: {result}")
print(f"Duration: {session.duration_ms:.2f}ms")
print(f"Actor: {session.actor}")

Audit — Blackbox-met-Window

from cortex import AuditTrail

trail = AuditTrail(".cortex/audit.json")
trail.record_session(session, query_hash="sha256:abc", response_hash="sha256:def")

stats = trail.stats()
print(f"Queries: {stats['total_queries']}")
print(f"Chain intact: {stats['chain_intact']}")

Architecture

STORE     TBZ envelopes + JIS levels
GATE      Multi-dimensional JIS claims (role × dept × time × geo)
AIRLOCK   Zero plaintext lifetime (mlock + zeroize in Rust)
AUDIT     Blackbox-met-window trail (WHO/WHEN, not WHAT)
TIBET     Immutable provenance chain
