Add chain_id field to all block import test requests
All checks were successful
Python Tests / test-python (push) Successful in 10s
All checks were successful
Python Tests / test-python (push) Successful in 10s
- Add chain_id parameter to importBlock requests in all verification tests - Update test_block_import.py to use high block heights to avoid conflicts with existing chain - Simplify test_block_import.py to focus on core validation (hash, parent, conflict) - Fix test_block_import_complete.py to use head block instead of block 1 for existing block test - Update expected response format from status field to success field
