Functional Requirements

Requirement 1: Min/Max Duration Set at Init

  • initialize() accepts min_duration parameter
  • initialize() accepts max_duration parameter
  • Values are stored in instance storage
  • Values persist across calls
  • Defaults are sensible (60, 2,592,000)

Requirement 2: create_proposal Rejects Out-of-Range Durations

  • Validation logic implemented
  • Rejects duration < min_duration
  • Rejects duration > max_duration
  • Accepts duration == min_duration
  • Accepts duration == max_duration
  • Returns InvalidDurationRange error
  • Error code is 21

Requirement 3: Limits Stored in Contract Config Storage

  • Uses DataKey enum variants
  • Stored in instance storage
  • Singleton configuration pattern
  • Efficient access (loaded with instance)
  • Proper key isolation

Bonus: Admin Can Update Limits

  • update_duration_limits() function exists
  • Admin-only access control
  • Respects contract pause state
  • Emits event for transparency
  • Allows dynamic adjustment

Error Handling

  • InvalidDurationRange error properly defined
  • NotAdmin error used in update_duration_limits
  • ContractPaused error checked in update_duration_limits
  • All error paths tested
  • Error messages are clear

Event Emission

  • duration_limits_updated event defined
  • Event emitted on successful update
  • Event includes min_duration
  • Event includes max_duration
  • Event uses correct topic

Documentation

  • IMPLEMENTATION_SUMMARY.md created
  • DURATION_LIMITS_TECHNICAL_REFERENCE.md created
  • DURATION_LIMITS_INTEGRATION_GUIDE.md created
  • CODE_CHANGES_DETAILED.md created
  • CHANGES_SUMMARY.md created
  • VERIFICATION_CHECKLIST.md created
  • Code comments are comprehensive
  • Function documentation is complete
  • Error documentation is accurate

Backward Compatibility

  • Breaking change identified (initialize signature)
  • Migration path documented
  • Other functions remain compatible
  • Existing proposals unaffected
  • Voting logic unchanged

Security Review

  • Admin authentication required for updates
  • Pause state respected
  • No integer overflow risks
  • Proper key isolation
  • No reentrancy risks
  • Input validation present

Performance

  • Instance storage used (efficient)
  • Minimal storage overhead (16 bytes)
  • No unnecessary reads/writes
  • Caching benefits from instance storage
  • Event emission is efficient

Testing Verification

Unit Tests to Implement

Duration Validation Tests

  • Test duration == min_duration (valid)
  • Test duration == max_duration (valid)
  • Test duration < min_duration (invalid)
  • Test duration > max_duration (invalid)
  • Test duration = 0 (invalid)
  • Test duration = u64::MAX (likely invalid)

Initialization Tests

  • Test initialize stores min_duration
  • Test initialize stores max_duration
  • Test initialize with various values
  • Test initialize can only be called once
  • Test initialize requires admin auth

Update Duration Limits Tests

  • Test admin can update limits
  • Test non-admin cannot update
  • Test update respects pause state
  • Test update emits event
  • Test new limits apply to next proposal
  • Test existing proposals unaffected

Query Tests

  • Test min_duration() returns correct value
  • Test max_duration() returns correct value
  • Test queries work after initialization
  • Test queries work after update
  • Test queries never revert

Integration Tests

  • Test full workflow with duration limits
  • Test multiple proposals with different durations
  • Test limit updates between proposals
  • Test error handling for invalid durations
  • Test event emission

Manual Testing Checklist

  • Deploy to testnet
  • Initialize with test values
  • Query limits to verify storage
  • Create proposal with valid duration
  • Attempt proposal with invalid duration (should fail)
  • Update limits as admin
  • Verify new limits apply
  • Attempt update as non-admin (should fail)
  • Pause contract and attempt update (should fail)
  • Unpause and retry update (should succeed)
  • Monitor event emission
