Add ERC: Zero-Knowledge Compliance Oracle

[DROOdotFOO]

This PR submits a new ERC ERC-8262: Zero-Knowledge Compliance Oracle.

Summary

A standard interface for on-chain verification of regulatory compliance (AML, sanctions screening, anti-structuring) using zero-knowledge proofs. Users generate proofs client-side that attest to compliance with jurisdiction-specific thresholds without revealing transaction amounts, counterparty identities, or screening details. No trusted third party or TEE is required.

Discussion

Forum thread (per EIP-1): https://ethereum-magicians.org/t/erc-zero-knowledge-compliance-oracle/28543

Scope

• Nine proof types (six unsigned + two single-signer + one M-of-N multi-signer), each backed by a separate ZK circuit with its own verification key
• IZKPVerifier (per-proof-type routing, batch verification, version history) and IZKPOracle (attestation submission, expiry, retroactive lookup) interfaces
• Jurisdiction configuration (EU AMLD6, US BSA, UK MLR, Singapore) with published thresholds in basis points
• Public input validation registries (config hash, merkle root, credential root, reporting threshold) to prevent context-spoofing replay
• Explicit trust-tier model in Rationale documenting what the standard does not prove (self-attested vs. provider-attested vs. credential-attested signals)

EIP-1 compliance

• Frontmatter complete (title, description, author, discussions-to, status, type, category, created, requires: 165)
• Sections in canonical order (Abstract → Motivation → Specification → Rationale → Backwards Compatibility → Test Cases → Reference Implementation → Security Considerations → Copyright)
• Cross-references use ./eip-N.md form
• All MUST/SHOULD/MAY usage follows RFC 2119
• markdownlint, codespell pass locally
• eipw passes locally with zero errors
• CC0 license

Notes for editors

• ERC-8262 self-claimed (next available above currently-claimed open-PR range). Happy to renumber if it collides with an in-flight assignment.

ERCs are application layer standards. They are not for product promotion or marketing purposes.
Recommend removing Xochi project name from the ERC.
