  MUJ428 LLC operates the MUJ428 Trust Layer ("VERIFY BEFORE ACT"), a machine-native trust preflight
  service for autonomous agents: an agent POSTs the consequential action it is about to take (PAY, BUY,
  DELEGATE, TRUST, ACCEPT, APPROVE, WRITE, RELEASE, COMMIT, PROPOSE) and receives an ALLOW / VERIFY /
  REQUIRE_VERIFICATION / DENY decision plus a portable Trust Receipt v1.3, while the caller keeps
  execution authority and MUJ428 never moves funds. The first 1,000 qualifying decisions per caller_ref
  are free with no account, key or wallet; paid continuation and the evidence-signal, reputation-check,
  milestone-attestation, trust-report and transaction-assurance services are settled in USDC on Base
  (eip155:8453) through x402. The same surface is published as a 24-operation OpenAPI 3.1 REST facade
  hosted on Supabase edge functions, a remote Streamable-HTTP MCP server listed in the official MCP
  registry, an A2A agent card with a Trust Reflex extension, an RFC 9727 api-catalog, an llms.txt,
  AGENTS.md and a tarball-distributed JavaScript client, all discoverable from agents.muj428.com.

    Agent2Agent surface: an agent card served from https://agents.muj428.com/.well-known/agent-card.json
    (name "MUJ428 Trust Reflex", version 1.8.3, provider MUJ428 LLC) declaring eleven skills — agent rescue
    beacon, trust reflex, evidence signal, reputation check, milestone attestation, trust report, transaction
    assurance, payment-plan discovery, agent router, heartbeat and trust requests — and two capability
    extensions (the MUJ428 Trust Kernel v1.0 and the Trust Reflex extension at https://agents.muj428.com/extensions/trust-reflex/v1,
    which adds a trust/evaluate JSON-RPC method activated with the A2A-Extensions header). supportedInterfaces
    names a JSONRPC binding at https://agents.muj428.com/a2a, which answers JSON-RPC 2.0 (an un-activated
    request returns -32600 asking for the extension header). The card omits protocolVersion and a top-level
    url, so it grades flavored against A2A 1.0.0. A canonical production copy with per-skill endpoints
    is also served at https://wepmhfjzckclvywolrek.supabase.co/functions/v1/trust-layer/.well-known/agent-card.json.
