Expand description

Bitcoin Core GetBlockScriptFlags (validation.cpp): start from SCRIPT_VERIFY_P2SH | SCRIPT_VERIFY_WITNESS | SCRIPT_VERIFY_TAPROOT, replace with the script-flag exception entry when present, then OR buried deployments (BIP66, BIP65, CSV, BIP147-at-SegWit). Same block-level bitmask is passed to script checks for every non-coinbase transaction.

This is not the Orange Paper ยง5.2.6 piecewise GetBlockScriptFlags (exception vs per-tx CalculateScriptFlags); use get_block_script_flags for that formulation. connect_block uses this function for mainnet consensus parity with Bitcoin Core.
