Verify it in your browser

Your browser downloads the bundle's SHA256SUMS manifest and the file(s) behind this page, hashes them with SHA-256 locally (WebCrypto), and compares. A match shows the record you are reading is the published one; it does not by itself prove who published it (see the signed claims registry and the bundle verifier for that).

Known limitations

• An in-process TESTED library; not hosted, not a deployed network. The directory and marketplace are local registries, not a public exchange.
• CAIN is NOT a bank, custodian or financial regulator. Escrow and settlement govern CONDITIONS only; units are SYNTHETIC and there is no payment rail or real money.
• CAIN-MSDP is an experimental CAIN protocol; there is no external adoption and it is not an industry standard.
• A2A/MCP integration is exercised via reference adapters; no external protocol support is claimed.
• Reputation, performance and quality graphs are evidence views built from in-process events; there are no real reviews, customers or market data.
• Dispute and arbitration are machine infrastructure layers; they are not legal advice, not arbitration and not a substitute for courts.
• The governance warranty covers governance conditions only; it is not universal safety and no insurance or underwriting exists.
• Moat and product maps are technical foundations only; no market moat, revenue or adoption is claimed.
• Mutation self-testing runs each mutant against the bench subset that exercises the mutated component.
• Scale rows reuse the E33 synthetic in-process benchmark; the exchange layer adds a 200-service discovery row.
• No third party has independently verified anything in this bundle.

The bundle's own README

CAIN-42 Evolution 36 -- Machine Agency Exchange Fabric#

A governed machine agency exchange: services are discovered, verified, negotiated with, contracted, hired and transacted with, and every consequential step still passes the deterministic kernel and E8. No economic object is authority. CAIN is not a bank, custodian or regulator; settlement units are SYNTHETIC. Verify with verify_e36.py.txt (see REPRODUCTION.md). Status: TESTED library, pre-production.
