GEPHYRA (γέφυρα, "bridge") — the living bridge / Toll Booth of Truth for AI agents.

Every router/gateway/bridge in history forwards bytes without caring whether they're true. GEPHYRA is the first bridge that inspects the truth of what crosses it in real time and stamps a tamper-evident receipt. It is the deployable surface of Mneme: Mneme is the brain; GEPHYRA is the face the agent world plugs into.

A single crossing runs through truth-customs, composing Mneme's organs:

1. IMMUNE — injection/collusion is quarantined (never crosses).
2. TOLL — the sender's honesty band sets scrutiny.
3. TRUTH-CUSTOMS — Mneme's 7-layer ACGV verifies the claim; a refuted claim is corrected before delivery (plus a deterministic arithmetic backstop).
4. CONSCIENCE — an overconfident claim gets a nudge back to the sender.
5. BLACK BOX — the crossing is recorded as a signed, chained frame.
6. STAMP — an Ed25519 NOTARY receipt that anyone verifies offline.

Resilient by design: every organ degrades gracefully; the bridge never throws and never drops traffic (truth engine down ⇒ crosses flagged UNVERIFIED).

Use

npx @mneme-ai/gephyra serve --port 17742
# POST /cross  {"claim":"...","fromAgent":"grok"}  → truth-customs + signed crossing
# GET  /status                                       → crossings + hallucinations caught

import { startServer, crossBridge, gephyra } from "@mneme-ai/gephyra";

const bridge = await startServer({ port: 17742 });

const r = await crossBridge(process.cwd(),
  { claim: "the body has 400 blood vessels", fromAgent: "grok" },
  { verify: gephyra.apoptosisTruthCustoms(process.cwd()) },
);
// r.disposition: "CORRECTED" — r.deliveredClaim is the fixed claim; r.receipt verifies offline

The truth-customs engine lives in @mneme-ai/core; this package re-exports it and adds the deployable HTTP server + the gephyra bin.
