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

  1. Store nodes and edges with tenant, source and fact class.
  2. Filter traversal by tenant and purpose at the storage layer.
  3. Flag contradictions instead of silently choosing a winner.
  4. 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 repositoryWhat the module says it is
cain/causality/graph.pyCAIN CAUSALITY — Causal Event Graph (Prompt CAUSALITY, Phase 3).
cain/runtime/passport.pyCAIN Sovereign — Agent Capability Passport (Prompt 7, Phase 8).
cain/trustnetPackage directory: antisibil.py, attacks.py, benchmarks.py, bilateral.py
cain/argus/memory_firewall.pyCAIN 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.
