The 2026 development
V7 described a Context Graph combining active context with retrievable organisational history.
The governance gap
A shared graph is a shared attack surface. One poisoned edge can influence every workflow that traverses it, and a tenant boundary that exists only in the query layer is not a boundary.
Where CAIN-42 fits: Moat 3 — Trust Graph
Core question: How is everything connected? Entities, resources, delegations and effects as a graph that can be traversed and audited.
Make the graph tenant-scoped and evidence-typed: every edge names its source, author and confidence class. Traversal cannot cross a tenant, and a node without provenance cannot become a premise.
How the wiring works
- Store nodes and edges with tenant, source and fact class.
- Filter traversal by tenant and purpose at the storage layer.
- Flag contradictions instead of silently choosing a winner.
- Record which subgraph supported each decision.
What is real today
LIBRARY Production code and tests exist in this repository; there is no hosted route for this exact use.
Graph and tenant-isolation primitives exist. No V7 implementation or customer graph is involved.
| Component in this repository | What the module says it is |
|---|---|
cain/causality/graph.py | CAIN CAUSALITY — Causal Event Graph (Prompt CAUSALITY, Phase 3). |
cain/runtime/passport.py | CAIN Sovereign — Agent Capability Passport (Prompt 7, Phase 8). |
cain/trustnet | Package directory: antisibil.py, attacks.py, benchmarks.py, bilateral.py |
cain/argus/memory_firewall.py | CAIN ARGUS — memory-to-authority firewall (Prompt 14, section 12). |
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.

What this page is not. CAIN-42 is not affiliated with, endorsed by, integrated into, or shipped with the organisation named in the 2026 item. The item is public context; the page describes how CAIN-42 would govern that class of capability. No page here claims a customer, a partnership, a certification, a patent, or a production integration. Prices are proposals. Built by a three-person team.
