Requirements Verification Report

Last reviewed: 2026-07-29 Status: Partially stale — see ⚠️ annotations below

Original Requirements (From User)

Description: Add delegation functionality for markets.

Requirements:

  1. Handle delegation requests
  2. Track delegation status
  3. Manage delegated permissions
  4. Support delegation revocation
  5. Provide delegation queries

Acceptance Criteria:

  1. Requests are handled
  2. Status is tracked
  3. Permissions are managed
  4. Revocation works
  5. Queries work

Technical Details:

  • Files: contracts/MarketDelegation.sol, test/MarketDelegation.t.sol
  • Libraries: OpenZeppelin

Implementation Verification

✅ Requirement 1: Handle Delegation Requests

Implementation:

  • ✅ requestDelegation() function implemented
  • ✅ Validates delegatee address (non-zero, not self)
  • ✅ Generates unique delegation IDs
  • ✅ Supports market-specific delegations (marketId parameter)
  • ✅ Supports global delegations (marketId = 0)
  • ✅ Supports time-limited delegations (duration parameter)
  • ✅ Enforces maximum delegations per delegator (100)
  • ✅ Enforces maximum duration (365 days)
  • ✅ Emits DelegationRequested event
  • ✅ Uses OpenZeppelin ReentrancyGuard

Status: ✅ FULLY IMPLEMENTED

✅ Requirement 2: Track Delegation Status

Implementation:

  • ✅ DelegationStatus enum with 4 states (PENDING, ACTIVE, REVOKED, EXPIRED)
  • ✅ activateDelegation() — transitions PENDING → ACTIVE
  • ✅ revokeDelegation() — transitions to REVOKED
  • ✅ Automatic EXPIRED status for time-limited delegations
  • ✅ getDelegationStatus() query function
  • ✅ isDelegationActive() query function
  • ✅ Status change events emitted
  • ✅ Active delegation counter maintained

Status: ✅ FULLY IMPLEMENTED

✅ Requirement 3: Manage Delegated Permissions

Implementation:

  • ✅ Permission enum with 5 types (TRADE, CREATE_MARKET, RESOLVE_MARKET, MANAGE_LIQUIDITY, ADMIN)
  • ✅ grantPermission() — single permission
  • ✅ grantPermissions() — batch operations
  • ✅ revokePermission() function
  • ✅ Permission grant tracking with timestamps
  • ✅ Prevents duplicate permission grants
  • ✅ Automatic permission revocation when delegation is revoked
  • ✅ Permission events emitted

Status: ✅ FULLY IMPLEMENTED

✅ Requirement 4: Support Delegation Revocation

Implementation:

  • ✅ revokeDelegation() implemented
  • ✅ Works for both PENDING and ACTIVE delegations
  • ✅ Automatically revokes all granted permissions
  • ✅ Updates status to REVOKED
  • ✅ Records revocation timestamp
  • ✅ Decrements active delegation counter
  • ✅ Emits DelegationRevoked event
  • ✅ Admin expireDelegation() for emergency control

Status: ✅ FULLY IMPLEMENTED

✅ Requirement 5: Provide Delegation Queries

Implementation:

  • ✅ getDelegation() — returns full delegation details
  • ✅ getDelegationStatus() — returns current status
  • ✅ isDelegationActive() — checks if active
  • ✅ hasPermission() — checks specific permission
  • ✅ getGrantedPermissions() — lists all permissions
  • ✅ getDelegationsByDelegator() — lists delegator's delegations
  • ✅ getDelegationsByDelegatee() — lists delegatee's delegations
  • ✅ getDelegationsByMarket() — lists market-specific delegations
  • ✅ getDelegationStats() — returns statistics
  • ✅ getTotalDelegations() — returns total count
  • ✅ getActiveDelegations() — returns active count

Status: ✅ FULLY IMPLEMENTED (11 query functions)

Acceptance Criteria Verification

✅ 1. Requests are handled — VERIFIED

✅ 2. Status is tracked — VERIFIED

✅ 3. Permissions are managed — VERIFIED

✅ 4. Revocation works — VERIFIED

✅ 5. Queries work — VERIFIED

Technical Details Verification

Files

File Expected Actual Status
contracts/MarketDelegation.sol ✅ Required ✅ Present (460 lines) ✅ VERIFIED
test/MarketDelegation.t.sol ✅ Required ⚠️ Not found ⚠️ STALE

⚠️ Stale claim (issue #610): The original report stated test/MarketDelegation.t.sol (650+ lines, 45 tests) was created and verified. As of 2026-07-29, this file does not exist in the repository. The corresponding test suite claims below are therefore unverified. test/VoteDelegation.t.sol exists (covers VoteDelegation.sol) but does not cover MarketDelegation.sol.

Libraries

  • ✅ OpenZeppelin Ownable — confirmed in MarketDelegation.sol
  • ✅ OpenZeppelin ReentrancyGuard — confirmed in MarketDelegation.sol

Code Quality Checks

✅ Security (verified against MarketDelegation.sol)

  • ✅ ReentrancyGuard on all state-changing functions
  • ✅ Access control (only delegators manage their own delegations)
  • ✅ Input validation (zero address, self-delegation)
  • ✅ Maximum limits enforced
  • ✅ Custom errors for gas efficiency

✅ Best Practices (verified)

  • ✅ Solidity 0.8.20
  • ✅ NatSpec documentation
  • ✅ Event emission for all state changes

Test Coverage

⚠️ Stale section (issue #610): The following test coverage claims were reported as verified but test/MarketDelegation.t.sol is absent from the repository. All sub-claims marked ⚠️ below are unverified until the test file is restored or recreated.

Category Claimed count Verified
Delegation Request Tests 7 ⚠️ Unverified (test file missing)
Delegation Activation Tests 6 ⚠️ Unverified (test file missing)
Delegation Revocation Tests 5 ⚠️ Unverified (test file missing)
Permission Management Tests 9 ⚠️ Unverified (test file missing)
Query Function Tests 7 ⚠️ Unverified (test file missing)
Expiration Tests 2 ⚠️ Unverified (test file missing)
Admin Function Tests 2 ⚠️ Unverified (test file missing)
Integration Tests 3 ⚠️ Unverified (test file missing)
Total 45+ ⚠️ Unverified

Alignment with Original Requirements

Original Requirement Implementation Status
Handle delegation requests requestDelegation() with full validation ✅ MATCHES
Track delegation status 4-state system with transitions ✅ MATCHES
Manage delegated permissions 5 permission types with grant/revoke ✅ MATCHES
Support delegation revocation revokeDelegation() with cleanup ✅ MATCHES
Provide delegation queries 11 query functions ✅ EXCEEDS

Contract alignment: ✅ 100% ALIGNED Test coverage: ⚠️ UNVERIFIED — test/MarketDelegation.t.sol is missing

Final Verdict

Criterion Status
Contract implemented ✅ contracts/MarketDelegation.sol present and complete
Test suite present ⚠️ test/MarketDelegation.t.sol not found — stale claim
OpenZeppelin used ✅ Confirmed
Security review ✅ Passed (contract-level)
CI / forge test ⚠️ Cannot be confirmed without test file

Action required: Restore or recreate test/MarketDelegation.t.sol to make the test coverage claims current.
