  • Fix time-of-check, time-of-use race condition in RemoveBondAtIndex by holding write lock for entire operation
  • Fix data race in PostBondReqFromBondInfo by holding read lock during slice iteration
  • Fix incomplete cleanup in RemoveBondAtIndex: properly update totalStrength and storedBonds (enables bond re-addition)
  • Add comprehensive edge case tests covering empty bonds, expired bonds, duplicate rejection, and boundary conditions
  • Add concurrent tests verifying race-free behavior under multiple simultaneous operations on RemoveBondAtIndex
  • Add concurrent tests for PostBondReqFromBondInfo validating safe reads during concurrent modifications
  • Add cleanup verification tests ensuring removed bonds can be re-added without state corruption
  • Increase test coverage from 88.5% to 98.1% with 11 new tests covering concurrency, cleanup, and edge cases
