ABS Core v4.3.3 -- Non-Repudiation as a Service

Non-Repudiation as a Service (NRaaS)

The only governance engine that produces legally admissible, cryptographic proof of every AI agent decision -- before execution, not after.

What Makes ABS Core Different

ABS Core is not an observability tool. It is not a prompt filter.

It is a non-repudiation layer that sits between AI agents and the tools they call. Every action is intercepted, evaluated against policies, cryptographically signed, and recorded in an immutable hash chain -- all with a 1.2ms median kernel latency.

The engine runs entirely on your infrastructure. Your data never leaves. Your keys never leave. Your governance never stops -- even without internet.

Performance

The Three Pillars

Core Capabilities

• Fail-closed enforcement -- DENY is the default. ALLOW requires proof.
• Ed25519 sovereign identity -- Each agent has a cryptographic keypair. Every action is signed.
• SHA-256 hash chain -- Immutable, append-only ledger. Tampering is mathematically detectable.
• RFC 3161 timestamping -- Independent temporal proof from a trusted authority. Admissible in court.
• NIST AI RMF mapping -- 19 controls mapped 1:1 to SovereignAuditRecord fields.
• License-aware governance -- Each record includes license_status (FULL / AUDIT_ONLY / GRACE_PERIOD) for audit traceability.
• 100% on-premise -- Engine, keys, ledger, and policies run on your server. Zero telemetry. Zero cloud dependency.
• SI-002: Ecosystem Invariant -- The Octagon pillars are a unified body. Amputation, transplantation, or moving projects from the root ecosystem is blocked by hardware-level policy.

Quick Start

npx @oconnector/mcp-gateway init

Then configure your MCP client to route through the ABS Core gateway:

{
  "mcpServers": {
    "abs-governance": {
      "command": "npx",
      "args": ["@oconnector/mcp-gateway", "watch"]
    }
  }
}

Every tool call is now intercepted, evaluated, and recorded.
