Summary

Implements the Governance Engine for VeriSphere (Task 7.2) with full proposal lifecycle management, voting logic, quorum enforcement, and execution authority pattern.

Changes

contracts/GovernanceHub.sol (82 lines)

  • Proposal struct with id, proposer, description, deadline, votes, execution state
  • createProposal() - Create proposals with configurable voting duration
  • vote() - Cast votes with duplicate vote prevention
  • executeProposal() - Execute proposals after deadline with quorum check
  • Quorum enforcement via constructor parameter
  • Execution authority pattern with onlyExecutionAuthority modifier

contracts/GovernanceEngine.sol (139 lines)

  • Extended voting contract with vote delegation
  • delegate() - Delegate voting power with loop detection
  • winningProposal() / winnerName() - Calculate and retrieve winner
  • addProposal() - Chairperson can add new proposals
  • ReentrancyGuard on vote and delegate functions
  • Proper event emissions for all state changes

Security Features

  • ReentrancyGuard prevents reentrancy attacks on voting functions
  • Access control via onlyExecutionAuthority, onlyChairperson, onlyOwner
  • Input validation with require statements on all public functions
  • Delegation loop detection prevents infinite delegation chains
  • Time-based voting periods with deadline enforcement

Tests

Added comprehensive Hardhat test suite with 30+ test cases:

test/GovernanceHub.test.js

  • Deployment and initialization
  • Proposal creation and validation
  • Vote casting and duplicate prevention
  • Deadline enforcement
  • Quorum requirements
  • Execution authority access control

test/GovernanceEngine.test.js

  • Voting mechanics
  • Delegation chains
  • Loop detection
  • Winner calculation
  • Chairperson management
  • ReentrancyGuard verification

Run tests:

npm install
npm test

Closes #192
