  "summary": "This PR updates ArgsManager to parse options that appear after non-option arguments (subcommands and positional parameters) using GNU-style conventions. Unrecognized options following a command now produce errors instead of being silently swallowed into the command's positional arguments, and the '--' separator is supported to terminate option parsing. Additionally, bitcoin-cli and bitcoin-tx are updated to consume the pre-filtered arguments from ArgsManager.",
  "problem": "In existing code, any argument following the first non-option argument was treated verbatim as a positional command argument. Consequently, trailing options such as -rpcwallet were silently ignored, potentially sending commands to the wrong wallet or triggering unexpected RPC errors when misspelled options were absorbed as positional values.",
