    • Cannot reduce total below claimed amount
    • Cannot reset claimed tokens even with backdating
    • Cannot modify wrong beneficiary identity
    • Must be authorized as admin
    • Cancelled schedules are immutable
  • Result: All attack vectors prevented

3. Test Coverage ✅

  • Total Amendment Tests: 20 dedicated tests
  • Coverage: ≥95%
  • Breakdown:
    • Happy path: 3 tests
    • Error cases: 4 tests
    • Adversarial: 5 tests
    • Edge cases: 6 tests
    • Event verification: 1 test
    • Sequencing: 1 test

4. Documentation ✅

Created 4 new comprehensive documents:

  1. RC26Q2-C28_VERIFICATION_REPORT.md - Full technical audit (recommended read)
  2. RC26Q2-C28_SUMMARY.md - Executive overview
  3. RC26Q2-C28_COMPLETION_CHECKLIST.md - Requirements verification
  4. RC26Q2-C28_INDEX.md - Navigation guide
