Zach Kelling 961c42e204 feat: add FHE example apps for all Pars PIPs

- data-seal: Verifiable Data Integrity Seal (PIP-0010/LP-0535)
  FHE-encrypted tamper-proof sealing with Public/ZK/Private modes,
  batch sealing, homomorphic verification

- content-provenance: AI & Media Content Provenance (PIP-0011/LP-7110)
  Model manifests, output attestation via homomorphic comparison,
  media derivation DAGs

- encrypted-crdt: Encrypted CRDT (PIP-0013/LP-6500)
  LWW-Register with FHE values, OR-Set with tag-based add/remove,
  Lamport timestamp conflict resolution, deterministic merge

- shadow-governance: Shadow Government Protocol (PIP-7010)
  Anonymous ministries, encrypted voting with homomorphic tallying,
  nullifier-based anti-fraud, quorum enforcement

Each example includes Solidity contracts, Hardhat tests, CLI tasks,
and README linking to corresponding PIP and LP specifications.

Shadow Governance - Anonymous Parallel Government

FHE-encrypted anonymous governance protocol for shadow government operations.

Implements: PIP-7010 / Shadow Government Protocol for pars.vote

Features

Shadow Ministries: Parallel government departments monitoring real governance
Anonymous Proposals: Submit proposals without revealing identity
Encrypted Voting: FHE-encrypted ballots — homomorphic tallying without decrypting individual votes
Nullifier-based Anti-Fraud: Prevent double-voting without linking votes to identities
Quorum Enforcement: Configurable quorum requirements

How It Works

Admin creates shadow ministries (Education, Health, Economy, etc.)
Anyone submits proposals tied to a ministry
Participants vote with encrypted ballots using unique nullifiers
After the voting period, tally decrypts aggregate counts (not individual votes)
Finalization checks quorum and majority to pass/reject

Anonymity Guarantees

Vote privacy: Individual votes are FHE-encrypted; only the aggregate is decrypted
Voter unlinkability: Nullifier = hash(secret || proposalId) — cannot link voter to vote
Proposal anonymity: Proposals can be submitted via relay/mixer for full anonymity

Quick Start

npm install
npx hardhat compile
npx hardhat test

# Deploy
npx hardhat task:deploy-gov

# Create a ministry
# (done programmatically in deploy or via admin functions)

# Create a proposal
npx hardhat task:propose --contract <addr> --content "Reform education" --ministry <id>

# Vote anonymously
npx hardhat task:vote --contract <addr> --proposal 0 --choice yes --secret "my-secret"

# Tally after voting period
npx hardhat task:tally --contract <addr> --proposal 0

# List ministries
npx hardhat task:list-ministries --contract <addr>

Go implementation: github.com/luxfi/fhe/cmd/vote — Boolean-circuit encrypted voting
Pars voting app: pars.vote — Production deployment
PIP-0012: Encrypted Voting protocol
LP-6500: fheCRDT Architecture
