Surviving Mutations Analysis

ReviewerPaymentV1 (1 survivor):

  • Mutation 21: Dust calculation edge case in fee distribution
  • Status: Low risk, test coverage adequate for main paths

AbbababaResolverV1 (11 survivors):

  • Mutations 1, 4, 5, 10, 11, 13, 14, 15, 22, 24, 26: OpenZeppelin initializer internals
  • Status: These are framework functions (__AccessControl_init, __UUPSUpgradeable_init) that are difficult to test directly
  • Risk: Low — framework code is battle-tested

Fuzz Testing Results

Bug Fixes

CI Pipeline Fixes

4 test failures fixed that were causing CI to fail:

  1. Token Support Test: Error message mismatch

    • "Not supported""Token not supported"
  2. Fee Calculations Test: Wrong function name

    • escrow.finalizeEscrow()escrow.finalizeRelease()
  3. Split Resolution Test: Wrong status enum

    • Expected 4 (Refunded) → 6 (Resolved)
  4. Cancellation Fees Test: Wrong test logic

    • Test tried to cancel after delivery (invalid)
    • Fixed to cancel after grace period as buyer
