Many teams now allow AI systems to draft customer-facing messages across support, CRM, and billing workflows.

This introduces a specific failure mode: AI can generate text that constitutes an irreversible business commitment (refunds, credits, billing changes, contractual promises).

Once emitted, the commitment exists. Detection after delivery is irrelevant.

This project implements a hard authority boundary.

Model -------- AI systems propose messages. They do not decide whether those messages are allowed to commit the company.

A gateway enforces that decision.

AI drafts message ↓ Authority Gateway ↓ Send | Block → Approval

Behavior --------- For each outbound message:

Inspect text for commitment signals

Classify outcome as reversible or irreversible

If reversible → allow

If irreversible → block and require explicit approval

Log decision and evidence

No attempt is made to assess advice quality, intent, or correctness. Only enforceability is considered.

API surface ------------ /v1/messages/send Enforces authority on outbound messages

/v1/support/messages/decide Decision-only endpoint for support systems Returns structured reasons and a safe fallback reply

Properties ---------- Deterministic enforcement

Idempotent execution

Explicit approval for irreversible actions

No reliance on prompt discipline or training hygiene

No agent autonomy

This is a sandbox implementation to test whether a narrow authority layer is useful in practice.

Feedback welcome from teams already routing AI-generated messages into real customer workflows.
